Study design (if review, criteria of inclusion for studies)

randomised controlled trial.


40 adults and children. The median age was 22.8 years (range 6.1-51.5 years); 27 patients were female. The cohort comprised 26 adults (aged >16 years), six teenagers and eight children (aged <12 years).


Tai Chi, a low-impact exercise and involves gentle, demanding movements. This study aimed to assess the feasibility, safety and acceptability of learning Tai Chi via an internet-based approach and compared patient-reported outcomes. Participants learnt eight Tai Chi movements; teaching was delivered in eight lessons over 3 months: delivered either via the internet or face-to-face.

Outcome measures

Assessments were at 3-monthly intervals over 9 months. Outcomes included health status, quality of life, sleep, mindfulness and instructor-led questions.

Main results

Feasibility and safety were demonstrated. Participants showed significant improvements in self-reported sleep, cough (both daytime and night-time), stomach ache and breathing. No differences in lung function, health status, quality of life, sleep or mindfulness was shown before or after completing the lessons.

Authors' conclusions

Tai Chi was safe and well tolerated; it was feasible to deliver individual lessons via the internet, reducing concerns regarding cross-infection, and appeared to improve self-reported symptoms.
