About

Recent work on large cohorts of chronic stroke (>6 months post-stroke) have shown that intensive training of the upper limb in the chronic stroke patients can lead to substantial motor and functional gains that are maintained at 6 months post intervention.

A very prolonged (12 weeks) and very intensive (5 hours daily) training applied to chronic patients after stroke brings a substantial gain both motor and functional which is maintained at 3 months post intervention.

Robotic rehabilitation have been shown to be as effective as any other treatment used in rehabilitation. But the methods of implementation remain widely debated. At that time, most robotic therapies have tried to reproduce functional movement mainly pointing objects.

We want to demonstrate that analytic movements of the elbow and the shoulder performed with the Luna-EMG robot can replace part of usual physiotherapy treatment with at least the same effectiveness on the recovery of fluid movements of the upper limb after a stroke.

Full description

This is a pilot study following a single case experimental design with multiple baselines across subjects (MBD).

People included in the protocol will benefit from 2 hours of daily treatment during 6 to 7.5 weeks. The first 2 weeks will be dedicated to baseline measurement of their upper limb (UL) status with daily treatment for balance and gait control without any treatment of the upper limb. The rest of the time will be dedicated to upper limb treatment exclusively. It will be divided into 2 UL training periods, one of them including a 30mn treatment with the luna EMG robot. The duration of second period will be randomly defined between 2 to 3.5 weeks and the last period will last 2 weeks. The treatment during the first UL treatment period will be randomly allocated to Luna EMG treatment or not. The next period will thus follow the inverse scheme (without if the first contains Luna EMG treatment). The fluidity will be assessed through pointing movements assessed every two days. Evaluation of motor deficiency (Fugl Meyer) and functional status (ARAT score) of the UL will be weekly assessed after the inclusion visit. 3D motion analysis of the UL will also be weekly performed.

All patients will benefit from a regular follow-up and from an organized care protocol. The sessions will be intensive, all subjects will be able to benefit from the new treatment (LUNA EMG). We can expect a direct individual benefit from the proposed intensive treatment, at least for precision of UL movements.

Experimental Scheme : A,B,C
Active Comparator group
Description:
The phase B treatment (1.5 hours a day, 5/7 days of conventional rehabilitation and 30mn a day, 5/7 days of treatment with the robot) is scheduled before phase C (2 hours a day, 5/7 days of conventional rehabilitation). The duration of phase B is randomized between 6 and 11 evaluations (2 to 3.5 weeks).
