Robotics for Rehabilitation of Hand and Fingers After Stroke
- Conditions
- Stroke
- Interventions
- Device: AMADEO
- Registration Number
- NCT03207490
- Lead Sponsor
- IRCCS San Camillo, Venezia, Italy
- Brief Summary
The major issue for a person who has suffered a stroke is the severe impairment affecting the hand and the high risk to have a poor recovery associated. Innovative approaches are needed in the next future, translating recent advances from neuro-engineering, into feasible devices for rehabilitation care. The FP7-EU project MYOSENS aims to translate known motor control logic from sEMG prosthetic control, to rehabilitation robotics. The target is to promote the closing of sensory-motor loop on the basis of intention to move, as detected from residual sEMG (i.e. Extensor Digitorum Communis, Flexor Digitorum Profundus).
- Detailed Description
The objectives of this pilot study are:
* to assess whether a clinical and kinematic effect might be induced providing a closed-loop control by sEMG signal for robot (i.e. Amadeo ®) assisted therapy of hand function
* to determine safety and feasibility of including robotic therapy into daily rehabilitation programs after stroke.
A total of 20 patients has been recruited, all of them received on daily basis 1 hour of robot therapy in adjunction to 1 hour of standard therapy. Overall the hour of robotic therapy include both subject preparation (15 minutes to place surface electrodes on the forearm and set the right position of sitting and upper limb) and delivery of exercises. The treatment protocol includes passive and active training of flexion and extension movements of the fingers. The passive part lasts 5 minutes, while the active one provides 25 total minutes divided into 5 exercises. The robot therapy lasts 15 consecutive sessions, 5 times a week, for 3 weeks.

Group Intervention Description Robot group AMADEO Receive 1 hour of AMADEO (robot-assisted therapy) for the hand and 1 hour of daily standard rehabilitation therapy
- Primary Outcome Measures
Name Time Method Change at Box and Block Test (BBT) Before treatment, then 3 weeks after Hand dexterity is measured by means of the BBT. The patient has to carry as much cubes as possible, one by one, from a container to another one in one minute. The test is performed with both hands.
- Secondary Outcome Measures
Name Time Method Change at Modified Ashworth Scale (MAS) Before treatment, then 3 weeks after Spasticity is measured using the MAS of five muscles: Pectoralis major, biceps, wrist flexors, flexor digitorum superficialis, flexor digitorum profundus (Total score = 20 points).
Change at Functional Independence Measure scale (FIM) Before treatment, then 3 weeks after FIM is an 18-item scale that assesses the degree of autonomy in carrying out activities of daily living (total score = 126 points).
Change at Fugl-Meyer Assessment Scale: Upper Extremity Motor Function (F-M UE) Before treatment, then 3 weeks after Motor function of the upper limb is measured by means of the Fugl-Meyer Scale. There are 3 values: 0 (severe impairment), 1 (moderate impairiment), 2 (preserved function)
Change at Nine Hole Pegboard Test (NHPT) Before treatment, then 3 weeks after NHPT measures the dexterity of the hand. Patient should insert 9 pins in the board. There are 9 pins. The number of pins inserted in 50 sec are registered or if the patient inserted 9 pins, then the time is registered.
Change at Reaching Performance Scale (RPS) Before treatment, then 3 weeks after RPS assesses the ability of subjects to reach an object (a cone). The cone is placed at both 4-cm (close) and 30-cm (far) distance from the subject. The subject is asked to reach and grab the cone if possible. The observer evaluates the quality of reaching instead of the grip strength (Total score = 36 points).
