WorksheetsQuestions on On and Off Phenomenon in Parkinson’s Disease
Total questions: 6
Worksheet time: 3mins
What is the on-off phenomenon in Parkinson’s disease?
A consistent improvement in symptoms throughout the day
Fluctuations in motor symptoms due to levodopa’s variable effectiveness
Permanent worsening of motor symptoms over time
A side effect of physiotherapy causing muscle fatigue
Which symptom is most likely to worsen during an “off” period in a PD patient?
Improved stride length during walking
Increased freezing of gait (FOG)
Enhanced balance and coordination
Reduced muscle stiffness
When do “on” periods typically occur in PD patients taking levodopa?
Immediately before a levodopa dose
30–60 minutes after a levodopa dose
Only during physiotherapy sessions
Randomly, unrelated to medication
How can feedforward cueing help manage motor deficits during “off” periods?
It increases levodopa absorption in the brain
It eliminates the need for exercise therapy
It provides external guidance for movement planning
It prevents all motor fluctuations
Why is explicit learning effective for PD patients during “on” periods?
It relies on automatic motor control unaffected by PD
It reduces the need for external cues
It only works in advanced PD stages
It engages cortical areas for conscious movement control
Which exercise strategy is most appropriate for reducing freezing of gait (FOG) in an “off” period?
High-intensity cycling without cues
Uncued complex dance routines
Static stretching without movement
Walking over visual cues like tape lines with verbal prompts
