The effects of Baduanjin on fine motor skills in mild and moderate Parkinson's disease: A randomized controlled trial.

Background: Fine motor impairment is common in Parkinson's disease (PD), which reduces patients' quality of life. There are few suitable targeted treatments. We conducted a clinical trial to determine whether Baduanjin Qigong exercise would increase fine motor skills in PD patients. Methods: Sixty PD patients (Hoehn-Yahr stage 1-4) with hand fine motor impairment were randomly assigned to the Baduanjin group and the physical activity group. Baduanjin group practiced Baduanjin exercise five times weekly for 40 min (warm-up 5 min, Baduanjin 30 min, cool-down 5 min). The usual physical activity groups maintained their habit of usual physical activities. The participants underwent assessments in the "ON" medication state at baseline and 4-week follow-up time points. The Purdue Pegboard Test (PPT) was used as the primary outcome to assess manual dexterity. The secondary outcomes included the Movement Disorders Society-Unified Parkinson's Disease Rating Scale, part III (MDS-UPDRS III), and the Parkinson's disease questionnaire (PDQ-39). Results: The results of PPT revealed the Baduanjin group showed statistically significant improvement in the "non-dominant hand" and "assembly" scores compared to the usual physical activity group (P < 0.05), but with no significant difference in "dominant hand" and "both hands" (P > 0.05). Additionally, the Baduanjin group showed better performance in the PDQ-39 (P < 0.05). Conclusion: Our study concludes that a 4-week Baduanjin exercise is effective in improving fine motor function and quality of life in patients with mild and moderate PD. The results suggest a promising intervention to be implemented in community or home settings for managing fine motor impairment in PD.
