Exercise in Parkinson's Disease

Physical activity in Parkinson's disease does far more than maintain general fitness. Aerobic exercise, strength work and balance training improve walking speed and stride length, reduce rigidity, build strength, and improve balance and gait; challenging, supervised balance work may reduce falls, which are a major cause of injury and loss of confidence. Exercise also helps the non-motor side of the condition, improving mood, sleep, fatigue, constipation and quality of life, and it gives people a sense of control over a condition that can feel unpredictable. There is interest in whether vigorous aerobic exercise can do more than treat symptoms. A phase 2 trial in selected people with early, untreated Parkinson's disease found that high-intensity treadmill training was feasible and may improve motor outcomes, but it was not designed to prove disease modification, which remains unproven and is still being tested. Benefit is seen both early and in established disease, and the least active people have the most to gain, so activity is encouraged from the moment of diagnosis rather than held back until symptoms are advanced.

There is no single best activity, and the most effective programme combines several elements tailored to the person's stage and preferences. Aerobic exercise such as brisk walking, cycling, treadmill work or Nordic walking builds cardiovascular fitness and supports overall fitness and function. Resistance training maintains the muscle strength that slowness and inactivity erode. Balance and agility work, including approaches such as Tai Chi, reduces falls and the fear of falling. Flexibility and stretching help with the stiffness and stooped posture that develop over time. Alongside these, Parkinson's-specific approaches add value: amplitude-focused training, delivered through programmes such as LSVT BIG, retrains the large, deliberate movements that the condition shrinks; cueing strategies use external rhythm and visual targets to overcome slowness and freezing; and dual-task practice rehearses moving while thinking. Many people enjoy and benefit from dance, particularly tango, from Parkinson's-specific group exercise, and from non-contact boxing classes, which combine agility, amplitude and aerobic effort. The activity a person enjoys and will keep doing is the one that helps most, and Parkinson's UK suggests aiming for around two and a half hours of activity a week, pushing to a level that feels like real effort.

Exercise is prescribed with the same structure as for anyone else, with Parkinson's-specific adjustments. Aerobic intensity is guided by a rating of perceived exertion (RPE) and the ability to talk, building towards a moderate to vigorous level; where a person can train safely, higher-intensity aerobic work is well tolerated by many and is introduced gradually with appropriate supervision, with intensity individualised to symptoms, fitness, medication and cardiovascular risk rather than set to a fixed heart-rate target. Timing matters: exercise is usually easier and safer during 'on' periods, when levodopa is working well, so sessions are planned around medication timing. Freezing of gait, where the feet feel glued to the floor, often responds to cueing, such as stepping over lines on the floor, marching to a metronome or a counted rhythm, or focusing attention on a large first step, and these strategies can be built into a home programme. Progression is gradual, and a physiotherapist with Parkinson's expertise can set a safe, motivating and individually tailored plan, drawing on the European Physiotherapy Guideline for Parkinson's Disease.

Exercise in Parkinson's disease is safe and strongly encouraged, but a few issues need attention. Falls are common because of balance impairment, freezing and postural instability, so balance and strength training and attention to the exercise environment are priorities, and supervised or supported activity is sensible for those at higher risk. Orthostatic hypotension, a drop in blood pressure on standing, is frequent and can cause dizziness or fainting. Slow position changes and good hydration are useful initial measures, but recurrent dizziness or near-fainting warrants orthostatic blood pressure measurement, medication review and clinical assessment rather than reassurance alone, and caution is sensible with exercises that involve rapid position change or standing after floor work. Fatigue and, for some, apathy or low motivation can be barriers, and short, regular, enjoyable sessions help more than occasional long ones. Current UK guidance advises that clinicians consider referring people early, around the time of diagnosis, to a physiotherapist with Parkinson's experience for assessment, education and advice including physical activity, and that Parkinson's-specific physiotherapy is offered when balance or motor-function problems develop, including gait difficulty, freezing or falls. Occupational therapy helps with everyday activities, and speech and language therapy addresses the voice and swallowing changes that can accompany the condition. The message is consistent and hopeful: activity started early, adapted sensibly and kept up over time can meaningfully change how a person lives with Parkinson's.

• •Exercise is a core treatment in Parkinson's disease, working alongside medication to improve gait, balance, strength and non-motor symptoms.
• •Vigorous aerobic exercise is feasible in selected people and may improve motor outcomes, but disease modification remains unproven; intensity is individualised, not set to a fixed heart-rate target.
• •Combine aerobic, resistance, balance and flexibility work with amplitude training such as LSVT BIG and cueing for freezing.
• •Plan sessions during 'on' periods when levodopa is working, and aim for about two and a half hours a week.
• •Falls and orthostatic hypotension are key risks; prioritise balance work, and assess recurrent dizziness with lying and standing blood pressure and a medication review.
• •Refer early to a physiotherapist with Parkinson's expertise, and involve occupational therapy and speech and language therapy as needed.
