Exercise is part of treatmentStrong evidence
NICE says to consider early referral to a physiotherapist with Parkinson's experience for advice that includes physical activity, and to offer Parkinson's physiotherapy for balance or movement problems; it doesn't name yoga. The American Physical Therapy Association (APTA) strongly recommends community exercise programmes, which in its trials included hatha and power yoga, and found results across types of exercise comparable. The Parkinson's Foundation and the American College of Sports Medicine (ACSM) list balance, agility and multitasking work "such as yoga, tai chi, dance, and boxing" on 2 to 3 days a week.

Anxiety, low mood and quality of lifeEmerging evidence
In 138 people (187 were screened), weekly 90-minute mindfulness yoga for 8 weeks eased anxiety and low mood more than stretching and resistance training, at 8 and 20 weeks, and improved Parkinson's quality of life scores. Easing anxiety and low mood partly explained the gains people noticed in daily life. In 159 people, yoga beat usual care for anxiety, movement and quality of life after 2 months, but only a meditation group also eased low mood and kept its movement and quality of life gains at 6 months.
Pooled trials agree on less anxiety and low mood with yoga. Both large trials were in Hong Kong, and people knew which group they were in, so they could have rated themselves more kindly.

Movement and mobilityEmerging evidence
Across 10 trials (359 people), yoga improved the movement rating scale by about 5.6 points more than control groups, against 2.5 points as the smallest change that matters, and people did the Timed Up and Go walking test about 1.7 seconds faster. Across 14 trials, yoga was safe and well accepted in mild to moderate Parkinson's. Against stretching and strength training, yoga's extra gain in movement was statistically significant but "clinically insignificant".
A 2024 Cochrane review of 154 trials (7,837 people) found that dance, and gait, balance and functional training, probably help movement by a moderate amount, while "mind-body training" might help a little, with low confidence; its summary doesn't say which practices that group includes.

Which exercise is best: no clear winnerMixed evidence
Comparisons of many trials disagree: yoga ranked first for movement or the walking test in some, dance came first for balance in another, and walking and dance came top in a third. The Cochrane review found "little evidence of differences between exercise types", and the APTA found community programmes comparable. Choose what you enjoy and will keep doing.

BalanceMixed evidence
Pooled yoga trials improved balance a little, and a review found tai chi, yoga and strength training all helped balance, tai chi the most. But the APTA found balance results from community exercise conflicting. In 27 people with a fear of falling, balance, walking and freezing scores improved within the yoga group over 8 weeks, but the waiting-list group improved on a balance test too, and only one walking measure differed clearly between the groups. Seated exercise on its own didn't improve balance in older adults, so the standing poses matter.

Falls: not tested for yogaMixed evidence
Exercise probably reduces falls in mild to moderate Parkinson's by 26% (12 trials, 1,456 people, moderate certainty). No controlled yoga trial in Parkinson's has counted falls: the only count is from 17 people who reported 6 falls during an 8-week yoga and occupational therapy programme and 10 in the 8 weeks before it.
Sources 12, 34, 13, 35
FreezingMixed evidence
Freezing scores improved within the yoga group in one 27-person trial, but the difference from the waiting-list group wasn't significant, and no trial has made freezing its main yoga outcome. Parkinson's UK's practical tips are the best guide: turn in a half circle, keep your support close and avoid distractions.

SleepMixed evidence
In a comparison of 16 trials, aerobic exercise improved sleep the most and mind-body exercise ranked lowest, and a review of mindfulness-based exercise found no clear effect on sleep.

Slowing Parkinson's: not shownMixed evidence
No yoga trial has measured whether Parkinson's progresses more slowly; a 160-person trial following people with early Parkinson's for 18 months is recruiting. NICE recommends no treatment as a way of protecting the brain in Parkinson's.

SafetyEmerging evidence
Yoga was safe in the Parkinson's trials: the main trials reported mild, short-lived knee, back or wrist pain and no serious problems. Across 94 yoga trials, side effects were no more common than with usual care or exercise. Published cases of harm cluster around headstand, shoulder stand, lotus and forceful breathing, which beginners are advised to avoid.
