Tai chi & qigong Gait & freezing Dementia & MCI Balance & falls prevention Sleep Non-motor symptoms

Researchers in China followed 330 people with early-stage, sporadic (non-inherited) Parkinson's disease for an average of 3.5 years. They split them into two groups: 143 people who attended tai chi classes for one hour, twice a week, and 187 people who received standard care but did no structured exercise. Disease progression was formally assessed at the start and at three follow-up points. This is an observational cohort study — participants were not randomly assigned to groups, which means the researchers cannot fully rule out that the tai chi group was, on average, healthier or more motivated from the start. That's an important caution when weighing the results.

The findings were striking across a broad range of symptoms. The tai chi group maintained far better motor function — including walking ability and balance — while the control group declined faster. Cognitive decline was also slower in the tai chi group. Beyond movement, the researchers tracked non-motor symptoms such as sleep quality, autonomic function (urinary and bowel control), and mood. Tai chi practitioners did better on all of these. They also needed lower doses of medication over time and had fewer complications such as dyskinesia (involuntary, uncontrolled movements) and hallucinations.

For someone living with Parkinson's, this is encouraging but not a green light to replace medication or physiotherapy. What makes it notable is the length of follow-up — most previous tai chi studies were short-term. This is the first to show benefits sustained over several years. The authors describe the results as hinting at potential "disease-modifying" effects, meaning tai chi might slow progression itself, not just mask symptoms — but that claim would need a proper randomised controlled trial to confirm. In practical terms: this is solid evidence to bring to your neurologist or physiotherapist as justification for adding tai chi to your care plan, particularly if you are in the early stages of the disease.

What this article adds

Tai chi & qigong
A 3.5-year observational cohort study (143 tai chi practitioners vs 187 non-exercising controls, all early-stage PD) found that twice-weekly 1-hour tai chi classes were associated with slower motor and cognitive decline, better autonomic function, improved sleep, and lower medication doses — the longest follow-up yet for tai chi in PD. The non-randomised design limits certainty, but the breadth and duration of benefits strengthen the case for tai chi as a complement to standard treatment.
Gait & freezing
Over 3.5 years, the tai chi group preserved walking ability and balance significantly better than non-exercising controls, whose motor function — including gait — declined more steeply. This is the longest follow-up data yet linking a movement-based practice to sustained gait outcomes in early-stage PD.
Dementia & MCI
Cognitive decline was measurably slower in the tai chi group than in controls across 3.5 years, adding long-term observational evidence that regular mind-body exercise may help protect against PD-related cognitive deterioration — though a randomised trial is needed to confirm this.
Balance & falls prevention
Balance was a primary outcome in this 3.5-year cohort; tai chi practitioners maintained significantly better balance than the no-exercise group, supporting twice-weekly tai chi as a practical, accessible complement to formal balance rehabilitation for people in the early stages of Parkinson's.
Sleep
Sleep quality was tracked across 3.5 years as part of a broad non-motor assessment; the tai chi group fared better than non-exercising controls, providing some of the longest-duration observational support yet for exercise-based approaches to PD sleep symptoms.
Non-motor symptoms
The study assessed autonomic function — including urinary and bowel control — over 3.5 years and found that tai chi practitioners showed better outcomes on these measures than controls, with fewer complications such as hallucinations and restless leg syndrome, broadening the evidence base for tai chi beyond motor benefits alone.
