About

The aim of this study is to test the feasibility of a constraint intervention combined with visual-spatial cueing strategy in patients with acute stroke to improve their daily life activities.

Full description

As part of treatment in acute stroke (from D0 to D14), the investigators were able to observe that despite motor recovery during physiotherapy sessions, it remained difficult for some patients to use their affected arm (AA) during activities of daily life (ADL). This mechanism of "learned non-use" would be due to a cognitive process decreasing the use of the AA and could partly explain that 75% of patients maintain an upper limb deficit at 3-6 month post-stroke.

In order to combat this phenomenon, a bottom up method (sensorimotor action on the deficit) of constraint-induced movement therapy (CIMT) has been developed and consists in immobilizing the unaffected arm to force the use of the AA.

This technique has proved its effectiveness in the chronic phase and has also recently been proven to improve motor performance in the acute phase. Transposing progress on ADL, however, remains difficult because CIMT does not contain adequate behavioral strategies.

To help the patient mobilize these strategies, coupling of CIMT with a top-down method (conscious action on motor skills) has been successfully tested as an intervention of an occupational therapist with the patient at least 1h / day. This intervention remains not compatible with the investigators care organization because the caregiver can not spend that amount of time with each patient.

Investigators therefore propose to associate CIMT with another top down technique: visual-spatial cueing (use of panels and/or visual messages to encourage the conscious use of the AA) and investigators want to evaluate the effectiveness of this treatment on learning transfer to ADL.

The objective of our study will be to test the feasibility of setting up such an intervention.

8 participants in 2 patient groups

Constraint-induced movement therapy

Experimental group

Description:

Patient's unaffected arm is restrained, by a glove including thumb, during activities of daily life (bathing, grooming, dressing and feeding = approx. 4h/day). Visual spatial cueing is displayed in the bedroom and the bathroom.

Treatment:

Other: Constraint-induced movement therapy

Usual care

No Intervention group

Description:

Usual care of the neurovascular unit. = No constraint, no cueing, and same physiotherapy intervention as experimental arm.
