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, the levels of evidence are limited, and new studies are needed.
Primary objective of the study is to demonstrate the non-inferiority of a therapeutic yoga program, compared to a conventional physical activity program, to improve balance of patients with chronic stroke sequelae.
Secondary objectives are to demonstrate the non-inferiority of the therapeutic yoga program in improving muscle strength and functional mobility, as well as its superiority in improving anxiety, depression, social reintegration and adherence to treatment.
The investigators will conduct a single-blind randomised controlled trial to study the effectiveness of a yoga programme compared to a conventional adapted physical activity programme in improving balance in chronic post-stroke subjects. The primary hypothesis is that yoga is non-inferior to conventional physical activity in improving balance in chronic post-stroke patients. The secondary hypothesis is that yoga is non-inferior to conventional physical activity in improving muscle strength and functional mobility, but superior in improving anxiety, depression, social reintegration and treatment adherence.
The experiment will take place in Normandy (France), at several sites in order to maximise recruitment and minimise travel for participants. The statistical power study indicates that 42 patients per group would be required. Subjects will be randomly assigned to one of the following programmes: the YOG'AVC programme or the FAME programme. The first will involve yoga sessions with postural, respiratory, and meditative work. The second will involve more conventional exercise sessions, based on a Fitness and Mobility Exercise Program (FAME) designed for stroke survivors. Both programmes included two 60-minute group sessions per week, for 12 weeks, plus one weekly home-based session (with video or paper support). Patients will be assessed at three points in the study: before the experiment (T0), after the 12-week experiment (T1), and 3 months later (T2). 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), 6-minute walk test (distance covered in meters), maximum isometric knee extension force with a manual dynamometer (newton), 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 100). Adherence to the programme will be assessed by a logbook, between T0 and T1 by the number of group and individual sessions completed, and between T1 and T2 by the number of self-reported sessions.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Yoga Exercise | Experimental | Subjects in the experimental group will be invited to participate in 60-minute yoga sessions twice a week for 12 weeks. Each session will include postural (asanas), breathing (pranayama), and meditative exercises. They will be adapted to the physical possibilities of the patients with the help of accessories such as chairs, straps, blankets, blocks. One additional session (60 minutes) per week, in autonomy, at home, will be recommended and accompanied by a video support. |
|
| Fitness and mobility exercise | Active Comparator | Subjects in the control group will be invited to participate in more conventional exercise sessions, based on a fitness and mobility exercise (FAME) program, 60-minute per sessions twice a week for 12 weeks. One additional session (60 minutes) per week, in autonomy, at home, will be recommended and accompanied by a video support. The effectiveness of this program has already been demonstrated in previous studies. |

| Physical activity | Other | Both groups will practice a physical activity adapted to their motor skills. They will have two group sessions (maximum 5 people per group) in a face-to-face setting, and one independent session at home supported by a video, each week. These programs last 12 weeks, and will be supervised by the same person, a physiotherapist. |

| Functional Balance | Berg Balance Scale : This test is used to quantitatively assess balance in older adults. In this 14-item scale, patients are asked to maintain positions and perform movement tasks of varying degrees of difficulty. Patients receive 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. This scale has been found to be reliable, valid, and is the most commonly used clinical and research scale for assessing balance in stroke patients. | Baseline |

| Maximum isometric muscle strength of the knee extensors | Manual dynamometer (Microfet2®). Subject is seated, knees and hips bent at 90°. The dynamometer is placed on the anterior surface of the tibia, 5 cm from the malleoli, with a tip adapted to the surface being tested. The subject is invited to push against the resistance, as if stretching the leg, with all the force he or she can muster. The measurement is repeated 3 times, and the score (in Newton) is established by averaging the 3 trials. Hand-held dynamometry is a reliable and valid method for assessing muscle strength in a stroke population. | Baseline |

| Reintegration to Normal Living Index | This self-questionnaire was developed to quantitatively assess the degree to which individuals who have experienced a traumatic or disabling illness are able to reintegrate into normal social activities (e.g., recreational activities, movement in the community, and interactions with family and other relationships). It is composed of 11 declarative statements (e.g. I move around my home as much as I want), and the patient gives a score between 0 and 2 (yes, partially, no). The total score is between 0 and 22 points, a high score indicates low reintegration. | Baseline |
