Robotic Rehabilitation of the Upper Limb After a Stroke (ROBOASSIST)
Rehabilitation Program With Robotic Assistance for the Improvement of Motor Performance and Functional Use of the Upper Limb in Subacute Hemiparetic. Multicenter Randomized Controlled Trial
Hemiparesis is the most common motor disorder after a stroke. Most patients do not recover functional use of their paretic upper limb.
The use of robotic assistance provides intensive motor training through a large number of repetitive movements, usually oriented and interactive tasks (pointing tasks, tracking paths tasks...). These feature have been demonstrated to be critical to stimulate brain plasticity after a brain damage. The InMotion Arm 2.0 manipulator works with an adaptive algorithm that provide patients with real-time Assistance-as-Needed™ desgned to enhance motor performance.
Hypothesis: In the sub-acute phase of stroke, the structured practice of a large number of repeated movements will increase motor function of the upper limb compared to conventional rehabilitation. Secondly, this practice will be more effective in a free active mode (without assistance) than an active assisted mode (Assistance-as-Needed™).
Expected secondary benefits: Subjective impression of improved use of the upper limb in activities of daily living and reduction of spastic cocontractions affecting the agonist and antagonist muscles during movements of the upper limb.
Objectives: This randomized controlled trial will evaluate the effects of structured repetition programs of arm movements, on the function of the hemiparetic upper limb and motor control, between 4 and 10 weeks after the stroke, using a robotic device with or without assistance in partial substitution of conventional rehabilitation care, compared to a program with conventional care alone.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
ACTIVE_COMPARATOR: Conventional rehabilitation
5 sessions / week of 1 hour of occupational therapy
|
Conventional rehabilitation implemented by an occupational therapist, involving stretching movements in submaximal passive amplitude, inhibition postures (Bobath), active efforts assisted of varied difficulty, exercises of direction of the arm towards a target with or without elbow support and grasping tasks, adapted to the capacities of the paretic upper limb.
|
ACTIVE_COMPARATOR: Robotic rehabilitation with assistance
5 sessions / week of 1 hour of rehabilitation of the upper limb with 30 min of conventional rehabilitation and 30 min of robotic rehabilitation with assistance.
|
Conventional rehabilitation implemented by an occupational therapist, involving stretching movements in submaximal passive amplitude, inhibition postures (Bobath), active efforts assisted of varied difficulty, exercises of direction of the arm towards a target with or without elbow support and grasping tasks, adapted to the capacities of the paretic upper limb.
Repetitive work of large numbers of targeted alternative movements with or without assistance.
The passage between with and without assistance taking place according to the evolution of performance judged by the investigator therapist.
Note that the duration of the training using the assisted mode should be at least 3 weeks, i.e. half of the total duration of treatment.

ACTIVE_COMPARATOR: Non-assistance robotic rehabilitation
5 sessions / week of 1 hour of rehabilitation of the upper limb including 30 min of conventional rehabilitation and 30 min of robotic rehabilitation without assistance.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Functional performance score change on Modified Frenchay Scale
Time Frame: Between the pre-rehabilitation state on the day of program start (Day1) and the state at the end of the program (Week6)
|
The scale measures active upper limb function in hemiparesis based on 10 everyday living tasks, each rated on a 10-point visual analogic scale.
Six tasks are bimanual and four are unimanual performed with the paretic hand.
Final score is an average of the 10 subscores (10 is the higher score).

Time Frame |
---|---|---|
Change in perceived function score on the Disability Assessment Scale (DAS)
Time Frame: between Day1(day of program start), Week6(end of the program) and Week22 (16 weeks after the end of the program)
|
The scale evaluates upper limb functional disability in patients with spasticity following stroke.
Patients are interviewed to determine the extent of functional impairment for the following 4 areas: hygiene,dressing, limb position, pain.The DAS Scale uses a 4-point rating scale according to the following criteria: 0(no disability),1 (mild disability), 2 (moderate disability) and 3(severe disability).
|
between Day1(day of program start), Week6(end of the program) and Week22 (16 weeks after the end of the program)
|
Change in perceived function score on the Global Subjective Self Assessment (GSSA)
Time Frame: between Day1(day of program start), Week6(end of the program) and Week22 (16 weeks after the end of the program)
|
Three questions were asked to the patient, relating to pain, stiffness-induced discomfort and active function.
Each rating was registered by the patient using a visual analogue scale ranging from 0 (worst pain imaginable, worst discomfort imaginable, arm totally useless, respectively) to 10 (no pain, no stiffness-induced discomfort, normal function, respectively).
