Read by symptom, without quizzes. Cases are fictional teaching scenarios; source films support multiple observations and do not represent the same number of distinct patients or diseases.
Understand the terms first
Separate the disease from its presentation
Clinical parkinsonism requires bradykinesia plus rest tremor or rigidity; Parkinson's disease is one possible cause. Tremor-prominent and gait-prominent presentations describe PD features that can change over time.
Bradykinesia requires slowness plus a progressive change during repetition: smaller or slower movements, or increasing hesitations or halts. Pain and joint problems also need consideration.
His right hand has gradually slowed over two years, making buttons and writing harder. A specialist has diagnosed PD. Today, the relaxed, supported right hand trembles; the tremor briefly reduces when he reaches for an object.
Watch the signs
Start with the complete comparison of two patients identified by the source. Relate the movement condition to the other clinical signs.

The first patient shows upper-limb action tremor during posture, reaching and drawing. The second shows predominantly left-sided rest tremor, a tremor that reappears after adopting a posture, and finger taps that slow and become smaller.
Compare
Compare the task and the accompanying movement signs, not just the amount of shaking. Action tremor can occur in PD; these are individual examples, not a rule that diagnoses every patient.
Document
Describe rest or action, side, changes during repetition and impact on everyday tasks. Record medication timing separately from what the video shows.
Interpret carefully: The diagnoses come from the source clinicians. A short video alone cannot establish a diagnosis or a formal PD motor subtype.
Annotated movement diagram (optional)
Optional 30-second demonstration
The complete observations and nursing explanation are written alongside.
Programmed teaching illustration, not patient footage or a diagnostic test.
When does the tremor appear?
Observe the relaxed, supported limb, then record what changes during reaching or holding an object.
What changes with repetition?
In this case, right finger taps are slow and progressively smaller. Slowness alone does not complete the assessment.
Connect the movement to the history
Symptoms began on the right, and the clinical record documents rigidity. The animation cannot confirm rigidity.
What the pattern suggests
Tremor is currently prominent in someone with established PD. This describes his presentation; hand tremor alone cannot diagnose a new patient or formally assign a motor subtype.
How does essential tremor differ?
Essential tremor typically affects both upper limbs during action. PD can also cause action tremor, and PD can occur without tremor. Consider bradykinesia, the examination and the timeline together.
Nursing priorities
Document the activity, affected side, functional impact and relationship to medication timing.
Check the individual's prescribed medication times. Do not delay doses to fit routine drug rounds, or independently stop or change treatment.
Report new or substantially changed symptoms for assessment by the clinical team.
Handover example
Right-hand tremor is present when relaxed and supported; repeated finger taps become smaller. Record the observation time, last medication dose and changes in tasks such as fastening buttons.
Established essential tremor: an action-tremor comparison
Ms Wong, 64. Fictional case.
She has had bilateral hand tremor for six years and has a specialist diagnosis of essential tremor. Holding a cup, using chopsticks and writing are troublesome. The clinical record does not document parkinsonian bradykinesia or rigidity. Her current concern is spilling drinks.
Watch the signs
Focus on the first patient’s action tremor and its effect on purposeful movement. The full two-patient comparison is available in the rest-tremor case.

Watch the first patient in the JAMA comparison, whose diagnosis is identified as essential tremor. The hands are observed during posture, reaching and drawing.
Compare
Compare the activity conditions within this example. The main rest-tremor case contains the second patient with PD for a broader comparison.
Document
Describe the task, sides affected and functional difficulty. Do not turn a drawing pattern or tremor frequency into a stand-alone diagnosis.
Interpret carefully: This is one patient selected by the source. Action tremor also occurs in PD; the clinical course and other findings still matter.
Name the activity
Describe what happens during posture, reaching and a functional task. A drawing can illustrate the problem but cannot establish its cause.
Compare both sides and the rest condition
Record which limbs are affected and what changes when the hands are supported. Avoid replacing this description with a simple yes-or-no tremor label.
Look beyond tremor
New progressive slowness, smaller repeated movements or other neurological findings need assessment even when an earlier ET diagnosis is recorded.
What the pattern suggests
The history supports an established ET case with functional difficulty from action tremor. ET is a different diagnosis from PD, rather than a PD subtype.
Action tremor does not automatically mean ET
PD may also include postural or kinetic tremor. Classification uses the clinical examination and course, not the size of the tremor or a single drawing.
Nursing priorities
Identify practical problems with eating, drinking, writing and medication handling.
Use the person’s assessed assistance and equipment plan; arrange occupational therapy review when function is affected.
Escalate new movement changes rather than assuming all new symptoms are part of the existing tremor diagnosis.
Handover example
Bilateral hand tremor affects holding a cup and writing. Record activity, side, change at rest and assistance needed; report any newly observed slowing or other neurological signs.
He has established PD and reports that buttons and chopsticks take longer. During an assessed finger-tapping task, the right hand starts slowly and the movements become progressively smaller. The left hand is less affected. The nurse also checks for pain or joint problems affecting the task.
Watch the signs
Watch a complete set of repeated movement tasks before interpreting speed, size and progression.
The people in these source films are not the fictional patients in this case. Watch at normal speed first, then pause to read. Original narration is in English; the observation guide is bilingual.
YouTube loads only when you press play and requires internet. Select Settings → Quality → 720p when available.
Watch the finger taps, hand opening and closing, and forearm rotation. Keep the first and later repetitions in view; note any slowing, smaller movements, hesitation or asymmetry.
Compare
A sequence becoming smaller or slower differs from a movement that is simply slow throughout. The examiner explains what to look for; do not call every demonstrated movement abnormal.
Document
Describe the task, side and visible change across repetitions. Add relevant pain, joint limitation and functional difficulty from the history.
Interpret carefully: This is an examination demonstration, not a score for the fictional case. Observation of slowness alone does not establish PD.
Keep the whole sequence in view
Compare the first movements with later repetitions. Describe size, speed, interruptions and differences between sides.
Distinguish decrement from constant slowness
Movements that progressively shrink or slow provide different information from movements that remain equally slow.
Connect to function and context
Ask what has changed in daily tasks and record medication timing. Check whether discomfort or limited joint movement affects performance.
What the pattern suggests
This fictional pattern illustrates bradykinesia assessment in established PD. A trained clinical assessment is needed; a video is not a rating-scale certification or a new diagnosis.
Slow movement has several possible explanations
Pain, restricted joints and other clinical problems can affect a task. Consider the movement pattern and the wider examination rather than speed alone.
Nursing priorities
Allow time for dressing, eating and communication; document the assistance that is actually needed.
Record the task, side and change across repetitions without inventing a clinical score.
Report a significant change with the medication schedule and functional impact; follow prescribed medication times.
Handover example
Right finger taps are slow and become smaller across the sequence. Record observation time, last prescribed dose, discomfort and the effect on buttons or utensil use.
Established PD: interpreting a rigidity examination
Ms Lau, 71. Fictional case.
She has established PD and describes stiffness during dressing. The specialist record documents increased resistance during passive movement of the right wrist. The nurse notices reduced arm movement but cannot infer the examiner’s tactile findings from appearance alone.
Watch the signs
Watch the assessment method and distinguish what is visible from what the examiner feels.

Watch how the examiner supports and passively moves the limb, with the person relaxed. Notice the difference between a movement performed by the person and one performed by the examiner.
Compare
Visible posture and slow movement do not reveal the resistance felt during a passive joint examination.
Document
When handing over, distinguish your observed movement findings from rigidity documented in a formal examination.
Interpret carefully: Rigidity is a hands-on examination finding. The video explains the method; it cannot let the viewer feel or confirm muscle tone remotely.
Identify who is making the movement
In the demonstration, distinguish the person’s active movement from the examiner’s passive movement of a supported limb.
Know what is not visible
The resistance felt by the examiner is not directly visible. Posture, facial expression and reduced arm swing do not confirm rigidity.
Separate stiffness, pain and function
Record the person’s description, discomfort and activity limitation alongside the formal examination result.
What the pattern suggests
Rigidity is a clinical examination finding. The video teaches the method and its limits; it does not allow remote confirmation of muscle tone.
A symptom description is not an examination result
A person saying “stiff” may be describing several different experiences. Keep the reported symptom separate from documented rigidity.
Nursing priorities
Document discomfort, dressing difficulty and the assessed support needed.
Use formal examination findings when handing over; perform assessments only within your training and local procedure.
Report new pain, restricted movement or functional deterioration rather than attributing everything to PD.
Handover example
The person reports stiffness during dressing; the specialist documented right-wrist rigidity. Current nursing observations are reduced active arm movement and the assistance needed for dressing.
Established PD: gait features without an observed freeze
Ms Ng, 74. Fictional case.
She has had PD for five years. During supervised mobility, steps are short, the right arm swings less and turning takes several steps. She continues stepping throughout this observation; no stepping block is seen. Her usual walking aid and level of assistance have been individually assessed.
Watch the signs
Keep the whole walk and turn in view. Describe the observed gait before naming the problem.
The people in these source films are not the fictional patients in this case. Watch at normal speed first, then pause to read. Original narration is in English; the observation guide is bilingual.
YouTube loads only when you press play and requires internet. Select Settings → Quality → 720p when available.
Watch both feet and arms throughout the walk and turn. Describe step length, heel contact, arm swing, symmetry and how the person changes direction.
Compare
A short-stepped walk is different from an episode in which stepping briefly cannot continue. Do not call all slow or short steps freezing.
Document
Document the walking situation, turns, observed balance and the assessed assistance needed. Keep observations separate from the falls history.
Interpret carefully: This chapter illustrates gait examination. It does not assign a PD subtype or demonstrate the fictional patient's history.
Keep feet and arms visible
Describe step length, heel contact, arm swing and symmetry throughout the sequence.
Watch the complete turn
Record how direction changes, balance and assistance rather than drawing a conclusion from one still frame.
Say whether stepping actually stops
In this case, stepping remains continuous. Short steps alone do not establish freezing.
What the pattern suggests
The case describes gait changes in established PD. The observed pattern informs mobility support; it does not assign a formal motor subtype or disease stage.
Short steps, freezing and falls are different observations
Describe each separately. A person can have short steps without freezing, and a falls history cannot be reconstructed from one walk.
Nursing priorities
Follow the assessed walking-aid and assistance plan; keep the route clear.
Arrange review of mobility and transfers when function or balance changes.
Record falls, medication timing and the situation; escalate new or substantially worse gait changes.
Handover example
Short steps and reduced right arm swing are observed; turning takes several steps. No stepping block was seen during this observation. Record the assessed support and any separate falls history.
Established PD with prominent gait difficulty and freezing
Ms Ho, 73. Fictional case.
She was diagnosed with PD seven years ago, initially with right-hand slowness and rigidity. Over the past year, starting, turning and passing through narrow doorways have become harder. At times, she wants to walk but briefly cannot take the next step.
Watch the signs
Watch the full patient sequence, including walking, turning, the doorway and floor-stripe cues. Interpret the observed response in the individual context.
The people in these source films are not the fictional patients in this case. Watch at normal speed first, then pause to read. Original narration is in English; the observation guide is bilingual.
YouTube loads only when you press play and requires internet. Select Settings → Quality → 720p when available.
Watch initiation, turning and the doorway. Keep the feet and attempted steps in view, then look at the use of floor-stripe cues and the movement that follows.
Compare
Compare stepping hesitation with forward progress. A stepping block differs from continuous short steps or a voluntary stop; a cueing response in one person is not a promise for everyone.
Document
Record the situation, observed steps, duration and assistance. Obtain medication timing and state from the clinical history; do not infer them from the video. Use cues according to the individual plan.
Interpret carefully: Freezing and wearing-off are related but different phenomena. This film does not instruct viewers to withhold medication, provoke freezing or pull someone forward.
Annotated movement diagram (optional)
Optional 30-second demonstration
The complete observations and nursing explanation are written alongside.
Programmed teaching illustration, not patient footage or a diagnostic test.
Describe the gait, not just the slowness
In this case, steps are short and turning takes several steps. Record the assistance needed and any falls.
Identify the freezing situation
Starting, turning and narrow doorways are useful contexts to document. Freezing is a brief difficulty initiating or continuing steps.
Check the course and medication timing
Gait problems became prominent after years of PD. Record medication timing, fatigue and distraction; do not automatically label every freeze as wearing-off.
What the pattern suggests
Gait and postural difficulties are now prominent in someone with established PD. This is not a separate, permanent type of PD or a disease stage that can be assigned from an animation.
Freezing is not unique to PD
Freezing can occur at different stages of PD and in other disorders, including PSP. Freezing and wearing-off can be related, but they are not the same phenomenon.
Nursing priorities
First support safe standing, assistance and a clear space. Do not pull the person forward.
Use assessed visual or rhythmic cues according to the individual's physiotherapy or rehabilitation plan. Arrange review of gait, transfers and walking aids.
Record the trigger, episode, falls and medication timing to inform the care plan.
Handover example
Brief stepping blocks occur when turning and near narrow doorways. Record the assessed level of assistance needed, the trigger, medication timing and whether the prescribed cueing strategy helped.
Within three years of her first progressive symptoms considered PSP-related, she has had repeated unexplained falls. A specialist examination documents slow vertical saccades. Recently, she has coughed when drinking and developed a wet-sounding voice after meals.

Hosted here in 720p with original speed and audio. Loads on request; the full source film runs 6:55.
The film presents consented clinical examples across eye movements, postural stability, movement and cognition. Watch the labelled findings rather than assuming every person has the same combination.
Compare
Use the specialist explanation to separate the different signs. The fictional case’s early-falls history is not the history of every person appearing in the source film.
Document
Record the timeline, observed function and formal examination findings separately. Escalate falls and swallowing concerns according to local procedures.
Interpret carefully: For observation only: the film includes specialist head-movement and guarded balance examinations. Do not copy these manoeuvres or provoke a fall. It is a teaching source, not permission to diagnose PSP from a video.
Annotated movement diagram (optional)
Optional 30-second demonstration
The complete observations and nursing explanation are written alongside.
Programmed teaching illustration, not patient footage or a diagnostic test.
Establish the falls timeline
The clue is repeated unprovoked falls within three years of the first progressive PSP-related symptom, rather than one accidental trip. Establish that symptom timeline with the clinical team.
Read the formal eye examination
Vertical saccades are rapid gaze shifts between upper and lower targets. Slowing is documented by a specialist here; arrows or tracking animations cannot confirm it.
Act on swallowing concerns
Coughing with drinks and a wet voice after meals warrant swallowing assessment. These signs are not specific to PSP.
What the pattern suggests
Early recurrent falls combined with vertical eye-movement abnormalities warrant specialist assessment for progressive supranuclear palsy (PSP). PSP is not a PD motor subtype, and these clues alone do not establish the diagnosis.
A characteristic combination, not every presentation
PSP has several presentations, and obvious eye-movement abnormalities may be absent early. Do not perform a shoulder-pull test on a person at high risk of falls simply to reproduce the illustration.
Nursing priorities
Arrange fall prevention and transfer assistance. Report the symptom course, falls history and formal eye findings clearly.
If swallowing is unsafe, stop the current feed, assess breathing and follow local procedures for medical and swallowing assessment. Do not repeatedly offer water to test swallowing.
Swallowing problems can interrupt essential medication. Promptly involve the prescriber and pharmacist in an administration plan; do not independently crush all medicines.
Handover example
Repeated falls occurred within three years of the first progressive symptoms considered PSP-related; the specialist record notes slow vertical saccades. New coughing with drinks and a wet voice have been escalated under the swallowing-safety procedure.
He reports difficulty looking down at steps. A specialist examination documents restricted voluntary vertical gaze and separately assesses the speed of saccades. The team reviews this alongside the wider neurological examination and symptom course. The symptom report alone did not establish PSP.
Watch the signs
Compare eye-movement range with speed; these are separate findings.
The people in these source films are not the fictional patients in this case. Watch at normal speed first, then pause to read. Original narration is in English; the observation guide is bilingual.
Hosted here in 720p with original speed and audio. Loads on request; the full source film runs 6:55.
The source first demonstrates vertical gaze limitation, then slow vertical saccades. Notice that these are labelled as different findings.
Compare
Compare how far the eyes move with how quickly they shift between targets. A delay before movement starts is a different observation again.
Document
Use the specialist’s documented finding: restricted range, slow saccades or both. Add the person’s reported visual difficulty and its functional effect.
Interpret carefully: Watch at normal speed. The film includes specialist head-movement assessment; do not copy the manoeuvre. Eye findings need the full clinical context.
Separate range from speed
A smaller range of eye movement is different from a slow movement between targets. Describe the finding that the source actually demonstrates.
Distinguish saccades from pursuit
Rapid gaze shifts between separate targets are not the same task as following a continuously moving target.
Use the formal examination record
Record whether the specialist described a speed abnormality, limited range or both. Head movement and neck examination require the appropriate clinical assessment.
What the pattern suggests
Vertical eye-movement abnormalities can contribute to assessment for PSP, but their meaning depends on the complete clinical evaluation. These findings are not interchangeable.
Slow saccades are not simply delayed initiation
A delay before moving the eyes is different from a slow movement once it begins. View the source at normal speed; slow playback cannot establish abnormal saccade velocity.
Nursing priorities
Document reported visual difficulty and its effect on safe walking, reading and daily tasks.
Provide mobility support according to the assessed plan and report new changes.
Communicate the formal eye findings and timeline. Do not reproduce specialist head-movement manoeuvres from the video.
Handover example
The person reports difficulty looking down; the specialist record describes restricted vertical gaze. Record the effect on mobility and distinguish the range finding from any documented saccade slowing.
She has a specialist diagnosis of PSP. At times after closing her eyes, she has difficulty initiating reopening, while remaining awake and responding verbally. The team is assessing the eyelid problem and how it affects mobility and communication. The nurse does not infer the precise mechanism from appearance alone.
Watch the signs
Describe the opening difficulty and associated visible features before applying a label.

Hosted here in 720p with original speed and audio. Loads on request; the full source film runs 6:55.
Watch the attempts to reopen the eyelids in the source’s labelled eyelid-opening example. Describe the visible sequence rather than inferring alertness or the underlying mechanism from this excerpt alone.
Compare
Difficulty initiating opening and visible forceful closure are not interchangeable descriptions. The full specialist film gives the wider PSP context.
Document
In a real assessment, record the sequence, duration, responsiveness and functional effect. The fictional case’s verbal responses are history, not something established by this short excerpt.
Interpret carefully: This is a brief but specific sign demonstration, not a complete assessment. It cannot identify the cause of a new eyelid problem in another patient.
Describe the sequence
Record what happened before closure, the attempted reopening and how long the difficulty lasted.
Describe associated features
Note responsiveness and any visible forceful closure, discomfort or other new symptoms without assigning a mechanism.
Connect to safety and function
Identify whether the episodes interfere with seeing the route, reading or communicating.
What the pattern suggests
Eyelid-opening difficulty can be part of a PSP presentation. A specialist assesses the cause; it is not enough to diagnose PSP and is not automatically the same as forceful eyelid closure.
A label should not replace observation
The source discusses eyelid-opening apraxia. Clinical interpretation distinguishes difficulty initiating opening from other eyelid problems; the nursing description should remain specific.
Nursing priorities
Pause mobility and provide the assessed support if the person cannot see the route safely.
Allow time for a response and confirm whether the person is awake and communicating.
Report the pattern and functional effect for clinical assessment; promptly assess a new change in responsiveness.
Handover example
After eyelid closure, reopening is delayed while verbal responses continue. Record the sequence, duration, visible associated signs and the impact on safe mobility.
A pattern warranting specialist review for atypical parkinsonism
Mr Tang, 70. Fictional case.
Within two years of his first progressive symptoms now suspected to be PSP-related, he has had several unexplained falls. A specialist has recorded an abnormal postural response during a guarded examination. The team reviews the falls history, examination and other possible contributors. This is not a nursing instruction to reproduce a pull test.
Watch the signs
Observe the specialist demonstration without reproducing the test. Keep the examination and the falls history separate.

Hosted here in 720p with original speed and audio. Loads on request; the full source film runs 6:55.
The source distinguishes early falls from different postural responses during specialist examination. Notice the clinical labels and the need for guarding.
Compare
A response to a clinician’s examination is not evidence of a multi-year falls history. Interpret the examination and the time course separately before combining them.
Document
Record actual falls, injuries, timing and circumstances. Attribute formal postural findings to the clinician’s examination and communicate the assessed mobility plan.
Interpret carefully: For observation only. Do not reproduce the shoulder-pull tests or provoke loss of balance. These examinations require trained clinicians and appropriate safety arrangements.
Establish the timing
Establish the first progressive PSP-related symptom and when recurrent unprovoked falls began. The timing is not restricted to the first motor symptom. One accidental trip is a different history.
Recognise a specialist assessment
The source may show a guarded postural examination. Observe the finding without copying the manoeuvre in a person at risk of falling.
Keep the differential open
The team must review the circumstances and other contributors. Early falls are a referral clue, not a stand-alone PSP diagnosis.
What the pattern suggests
Repeated unprovoked falls early in the course can be an important PSP clue when combined with the other clinical findings. The immediate nursing priority is safe mobility and escalation.
Falls history and a pull-test result are different
A filmed response to an examiner does not demonstrate a multi-year history of spontaneous falls. Record the history and examination separately.
Nursing priorities
Use the individual falls-prevention and transfer plan, with the assessed assistance and equipment.
Escalate recurrent unexplained falls and any injuries according to local procedure.
Provide a clear symptom and falls timeline to the team; do not provoke a fall to obtain a demonstration.
Handover example
Several unexplained falls occurred within two years of the first progressive symptoms suspected to be PSP-related. A separate specialist examination records an abnormal postural response. Record injuries, circumstances and the current transfer and mobility support plan.
A guide to organising observations, not a complete differential diagnosis or diagnostic tool.
Pattern
Features to consider
Keep in mind
Parkinson's disease (PD)
Bradykinesia plus rest tremor or rigidity establishes parkinsonism. A specialist then considers the history, exclusions and supportive features to determine whether the cause is PD.
The balance of tremor and gait problems can change. The presence or absence of hand tremor alone cannot classify the condition.
Essential tremor (ET)
Typically bilateral upper-limb action tremor. The MDS classification requires at least three years and no other established neurological signs.
ET is not a PD subtype. PD can also cause action tremor, so rest versus action is not an absolute dividing line.
Progressive supranuclear palsy (PSP)
Early recurrent unprovoked falls with slow vertical saccades or other vertical eye-movement abnormalities warrant specialist assessment.
Some PSP presentations lack this early characteristic combination. One fall or eye finding cannot establish a diagnosis.
Multiple system atrophy (MSA)
Prominent autonomic problems, such as urinary dysfunction or orthostatic hypotension, alongside parkinsonism or cerebellar signs need assessment.
PD, medicines and dehydration can cause similar problems. A single low blood-pressure reading cannot diagnose MSA.
Drug-induced parkinsonism
Check the timing of symptoms against newly started or increased medicines, including some dopamine-receptor blockers.
The presentation can also be asymmetric. Refer to the prescriber rather than independently stopping medicines abruptly.
Three checks before handover
Time-sensitive medication Give medicines at individually prescribed times. If oral doses cannot be taken or may be missed, involve the prescriber and pharmacist early.
Mobility and swallowing safety Arrange movement assistance according to the individual assessment. Coughing during meals, wet voice or other swallowing concerns need timely assessment.
A sudden change today Breathing difficulty, acute altered awareness or sudden new focal neurological symptoms need immediate assessment and help under local emergency procedures.
Sources and clinical boundaries
A single sign or animation cannot establish a diagnosis. This material has not received clinical sign-off in Hong Kong. Follow individual prescriptions and your institution's assessment and escalation procedures.
