About

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.

Full 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.

---

11 participants in 2 patient groups

TELEYOG'AVC Group

Experimental group

Description:

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.

Treatment:

Other: tele-yoga

Wainting list Group

No Intervention group

Description:

The subjects in the control group will be asked not to change their habits during the entire experimental phase (T0-T1). They will be able to benefit in turn from the tele-yoga program (free of charge), if they wish, once the evaluations in T1 are completed.
