Overview
Brief Summary
Hand recovery following cerebral stroke is complex and requires intensive training. The investigators aimed to evaluate the feasibility and efficacy of robot-assisted hand rehabilitation compared to physiotherapist-guided treatment in recovering dexterity and hand strength in hospitalized sub-acute hemiplegic patients. Design. 30 patients affected by stroke from cerebral ischemia or hemorrhage (Ashworth spasticity index <3) were randomized. Patients in the Treatment group received intensive hand training with Gloreha, a hand rehabilitation glove that provides computer-controlled, repetitive, passive mobilization of the fingers, with multisensory feedback. Patients in the Control group received conventional intensive hand rehabilitation under physiotherapist guidance. Hand motor function (Motricity Index, MI), fine manual dexterity (Nine Hole Peg Test, NHPT) and strength (Grip and Pinch test) were measured at baseline and after rehabilitation, and the differences between final and basal results were compared between groups.
Detailed Description
Upper limb recovery, particularly that of the hand, is complex in patients with cerebral stroke and requires an intensive approach. Regarding upper limb rehabilitation, several research groups have developed robotic devices to provide passive and/or active movements. Their use appears to reduce the motor deficit of the arm and affected hand and to improve hand function both at the wrist and fingers. Hence, the evidence supporting specific robot-assisted rehabilitation of the hand is very promising even if further study is required.In particular, evidence is limited about the benefit of passive exercises and mobilization of the hemiplegic upper limb following stroke, and further research is called for. In this study the investigators used Gloreha, a new hand rehabilitation glove that provides computer-controlled, repetitive and passive mobilization of the fingers, with multi-sensory feedback. The purpose of the study was to evaluate in the rehabilitation of patients with ischemic or hemorrhagic stroke in the sub-acute phase: 1) the feasibility of this new neuromotor rehabilitation device 2) its efficacy in improving arm function abilities, and 3) the costs involved. Post-stroke patients admitted for inpatient rehabilitation between May 2013 and January 2014 were screened for enrollment. Eligible patients were randomly assigned, following a simple randomization procedure (computerized random numbers) conducted independently of the study investigators, to Treatment group or Control group, on a 1:1 ratio.

Outcomes
Primary Outcomes
Efficacy in Improving Arm Function Abilities Measured by the Change From Baseline in Nine Hole Peg Test at End of Inpatient Rehabilitation.
Time Frame: Baseline and end of the study after 30 sessions, an average of 6 weeks
Nine Hole Peg Test (NHPT), a measure of coordination and mono-manual dexterity. It consists in collecting 9 pegs and inserting them into holes in a wooden base within a 50-sec time limit. The score is the average number of pegs inserted/tests performed.
Efficacy in Improving Arm Function Abilities Measured by the Change From Baseline in Motricity Index at End of Inpatient Rehabilitation
Time Frame: Baseline and end of the study after 30 sessions, an average of 6 weeks
Motricity Index, a measure of the motor function of the paretic upper limb. Motricity Index used to measure the ability to activate a muscle group to move a body segment through a range of motion and resist external force. The upper extremity motricity index includes: 1. pinch grasp, 2. elbow flexion, and 3. shoulder abduction. The total upper extremity score involved adding one to the sum of the three actions. The score of each action ranges from 0 (no ability) to 33 (maximal ability) with a maximum possible score=100.
Number of Patients Who Completed the Hand Rehabilitation Program
Time Frame: Through study completion. The specific hand interventionn consisted of a total of 30 sessions, lasting 40 min/day, for 5 days/week , from admission to discharge in the Rehabilitation Centre, over a period of about 6 weeks.
Side Effects Using Gloreha Device
Time Frame: Through study completion. The specific hand intervention consisted of a total of 30 sessions, lasting 40 min/day, for 5 days/week , from admission to discharge in the Rehabilitation Centre, over a period of about 6 weeks.
The feasibility of the device was assessed in terms of side effects (the physiotherapist was required to report any adverse events occurring during the study in regard to the use of Gloreha);
