How do Parkinson disease and atypical parkinsonism affect mobility?
Parkinsonian movement patterns influence initiation, automaticity, turning and daily participation. The PT’s task is to observe what changes across medication cycles and environments, then match exercise and cueing to functional goals.
Build the clinical picture
Recognize movement patterns without over-diagnosing
Parkinson disease (PD) is typically characterized by bradykinesia with rigidity and/or rest tremor. Slowness with progressive reduction in amplitude during repeated movement, reduced arm swing, small steps, impaired turning and freezing may affect function. Postural instability, cognitive changes, sleep, mood and autonomic symptoms can also matter. A diagnosis is made medically, and a tremor or slow walk alone is not specific to PD.
Atypical parkinsonism such as progressive supranuclear palsy (PSP) can involve early prominent falls, eye-movement difficulties, dysphagia and other features not typical of uncomplicated early PD. New swallowing issues, rapidly changing gait, unexplained falls or other red flags need medical/team follow-up.
Translate motor learning into movement practice
Exercise, task-specific gait and balance training, external cueing, aerobic activity and resistance training can each help address selected limitations. A therapist may trial visual step targets, rhythmic auditory cues or simple movement-amplitude prompts, but the cue must be matched to the person and the task. The original lecture’s ‘25% faster metronome’ is not a universal starting point.
Build toward meaningful activities: standing from a dining chair, turning through a doorway, avoiding freezing at thresholds, carrying items safely or getting into bed. Observe retention and performance both with and without prompts. Dual tasking may be added gradually when safe rather than on every first attempt.
Coordinate medication and functional timing
Ask about usual medication schedule, perceived on/off periods, dizziness/orthostasis, fatigue and cognitive change. Test at consistent and meaningful times when possible. A diagnosis label or Hoehn–Yahr stage does not fully describe falls risk, community endurance or environmental demands.
The 2022 ANPT Parkinson disease clinical practice guideline supports evidence-informed exercise selection. Specialized amplitude-based programs such as LSVT BIG are options for suitable patients, not a universal replacement for individualized, task-specific PT.
At a glance
| PD | Bradykinesia, rigidity and variable automaticity; medication state often matters |
| PSP and other atypical syndromes | Potential early postural instability, ocular/bulbar findings or atypical course |
| PT priority | Function, safe mobility, meaningful movement practice and reassessment |
Clinical reasoning
A patient walks adequately in a clear hallway but freezes while turning into a narrow bathroom. What should you test before merely increasing leg-strength exercises?
Answer: Examine threshold/turning context, cue responsiveness, falls and dual-task demands, motor timing and medication state. Train safe, relevant movement patterns with guarding.
Check your understanding
Why might a patient demonstrate a normal manual muscle grade yet have major difficulty initiating a step?
