Brief Summary

Stroke is a major health problem and can cause long-term disability. Among these sequelae, there are balance and mobility disorders, but also a higher rate of anxiety or depression disorders. This impairments impact activity of daily living, and social reintegration. That why the investigators need to explore options for long-term sustainable interventions that which takes into account the patient as a whole. In particular, regular physical activity is recommended, but it must be adaptable to the patient's impairments. Teaching yoga may be an interesting option. Indeed, yoga is a mind-body practice which become increasingly widespread in the world. Recent studies highlight positive effect of yoga for this population. However, accessibility to yoga classes can be limited by many factors: lack of transportation, lack of available health professionals, confinement requirements... Therefore, it seems relevant to evaluate the effectiveness of yoga delivered through tele-rehabilitation.

The main objective of this study is to evaluate the effectiveness of a tele-yoga program adapted to stroke survivors to improve their functional balance.

The secondary objectives are to evaluate the effectiveness of the adapted tele-yoga program in improving functional mobility, anxiety, depression and reintegration into normal life.

Detailed Description

The investigators will conduct a single-blind randomised controlled trial to study the effectiveness of a tele-yoga programme compared to an inactive control group in improving balance in chronic post-stroke subjects. The primary hypothesis is that yoga is effective in improving balance in chronic post-stroke patients. The secondary hypothesis is that yoga is effective in improving functional mobility, anxiety, depression, and reintegration into normal life.

The experiment will take place in metropolitan France, and the whole experimental procedure (recruitment, evaluation, experimentation) will take place at a distance, via information and communication technologies. The statistical power study indicates that 15 patients per group would be required. Subjects will be randomly assigned to one of the following groupe: the TELEYOG'AVC programme or the inactive control group. The TELEYOG'AVC programme will involve yoga sessions with postural, respiratory, and meditative work delivered by videoconference. This programme includes two 60-minute group sessions per week, for 12 weeks, plus one weekly home-based session (with video support). The control group will be instructed not to change their habits during the 12 weeks of experimentation, then after the final assessment (T1) they will be able to benefit from the TELEYOG'AVC programme if they want. Patients will be assessed before the experiment (T0) and after the 12-week experiment (T1). The assessments will be carried out blind, using a protocol built around the International Classification of Functioning and Disability (ICF). The main criterion is balance, assessed by the Berg balance scale (0-56 point scale). The secondary outcomes will be assessed by: Timed Up and Go Test (timed task in seconds), 5 time-sit-to-stand (timed task in seconds), the activities-specific Balance Confidence Scale - Simplified (questionnaire in %), State-Trait Anxiety Inventory (2 questionnaires out of 80), Beck Depression Inventory (score out of 63), Reintegration to Normal Living Index (score out of 22). Adherence to the programme will be assessed between T0 and T1 by the number of group and individual sessions completed.

Arm && Interventions

Group	Intervention	Description
TELEYOG'AVC Group	tele-yoga	The subjects of the experimental group will be invited to participate in 60-minute tele-yoga sessions, twice a week, for 12 weeks. The sessions will take place via the Zoom videoconference software, in small groups (maximum 5 people) in order to adapt the practice to the possibilities of each subject. In addition, an additional weekly session, independently at home, will be recommended to participants, accompanied by a pre-recorded video support hosted on YouTube.

Primary Outcome Measures

Name	Time	Method
Berg balance scale	Pre-treatment : at three months	This test quantitatively assesses balance in adults. In this 14-item scale, patients are asked to maintain positions and perform movement tasks of varying difficulty. Patients are given a score between 0 and 4 on their ability to respond to dimensions of balance. An overall score can be calculated from a total of 56. The higher the score, the better the balance.

Secondary Outcome Measures

Name	Time	Method
Five Times Sit to Stand	Pre-treatment : at three months	It's a test based on the realization of a functional task: the subject must stand up and sit back down on a chair without armrest. He must perform this task five times in a row, and he is timed to obtain a score in seconds.
Activities-specific Balance Confidence Scale - Simplified	Pre-treatment : at three months	This questionnaire consists of 16 questions that require the patient to rate his or her confidence that he or she will not lose balance while performing the listed activities. For each of the 16 activities, he/she must rate this confidence from 0 (not at all confident) to 3 (very confident). The total score is given as a percentage.
Beck Depression Inventory	Pre-treatment : at three months	This self-administered questionnaire includes 21 items identifying symptoms and attitudes associated with depression. Each item is rated on a severity scale ranging from 0 to 3, with a total score ranging from 0 to 63.
Timed Up and Go Test	Pre-treatment : at three months	It is a test based on the realization of a functional task, where the subject must get up from a chair, walk 3 meters, turn around and return to sit down. The subject is timed during the execution and a score in seconds is established.
State-Trait Anxiety Inventory	Pre-treatment : at three months	t includes two separate (self-administered) scales to assess state anxiety (STAY Form Y-A), and treatment anxiety (STAY Form Y-B). Each of the scales consists of 20 propositions, Scale A to assess how subjects feel in the moment, Scale B to capture how subjects generally feel. Each answer to a proposition of the questionnaire corresponds to a score from 1 to 4: 1 indicating the lowest degree of anxiety, 4 the highest degree. A total score is given out of 80.
Reintegration to Normal Living Index	Pre-treatment : at three months	This questionnaire is composed of 11 declarative statements accompanied by a 3-point rating. The scores of each individual item are added together to obtain a total score ranging from 0 to 22 points, with higher scores indicating worse reintegration.
