The hand brace is worn on the dorsal side of the impaired hand with 2 surface sensors attached to the extensor and flexor muscles of the arm to detect the surface electromyographic signals (sEMG) for active participation during exercise. The sEMG signals are processed so the patient can visualise the active movement of the muscle where sEMG electrodes are positioned. No electrical current is applied to the patient.
Intended Use The Hand of Hope therapy device is intended for use in patients that require hand and forearm rehabilitation. Potential goals for the use of HOH could be, but not limited to the following:
Motor learning via interactive use of the biofeedback system
Help initiation of the voluntary muscle contraction and voluntary movement
Maintain voluntary muscle contraction and the voluntary movement
To enhance voluntary participation in a rehabilitation setting
Indications
Decreased muscular activity after Stroke, Spinal Cord Injury, Hand / Finger injury
Difficulty to self-initiate, control or maintain voluntary muscle movement
Impaired coordination of voluntary movement of the upper limb
Hand of Hope is used to facilitate:
Initiation of voluntary muscle contraction
Motor control and coordination
Muscle relaxation
Motivation
Control of abnormal muscle activity
Continuous reinforcement of the correct responses
Training Modes Different training modes allow the therapist to customize the level of assistance that HOH provides. The difficulty level of each mode can be adjusted according to the user’s need.
Continuous Passive Motion Movements are passively repeated over time. Two CPM patterns are available for training: hand opening & grasping.
