Spastic hypertonia causes loss of range of motion (ROM) and contractures in patients with post-stroke hemiparesis. The pronation/supination of the forearm is an essential functional movement in daily activities. We developed a special module for a shoulder-elbow rehabilitation robot for the reduction and biomechanical assessment of pronator/supinator hypertonia of the forearm. The module consisted of a rotational drum driven by an AC servo motor and equipped with an encoder and a custom-made torque sensor. By properly switching the control algorithm between position control and torque control, a hybrid controller able to mimic a therapist’s manual stretching movements was designed. Nine stroke patients were recruited to validate the functions of the module. The results showed that the affected forearms had significant increases in the ROM after five cycles of stretching. Both the passive ROM and the average stiffness were highly correlated to the spasticity of the forearm flexor muscles as measured using the Modified Ashworth Scale (MAS). With the custom-made module and controller, this upper-limb rehabilitation robot may be able to aid physical therapists to reduce hypertonia and quantify biomechanical properties of the muscles for forearm rotation in stroke patients.

Abstract Introduction: Individuals with stroke sequelae present changes in the postural alignment and muscle strength associated with hemiplegia or hemiparesis. Mirror therapy is a technique that aims to improve the motor function of the paretic limb. Objective: The aim of this study was to evaluate the effect of mirror therapy, associated with conventional physiotherapy, for range of motion (ROM), degree of spasticity of the affected upper limb, and the level of independence in the activities of daily living (ADL) of chronic patients after stroke. Methods: This was a quasi-experimental (before and after) study. The study included ten stroke survivors undertaking physiotherapy and presenting with upper limb paresis. The following gauges were used for the present study: goniometry, the Modified Ashworth Scale, Fugl-Meyer and Barthel Index. Fifteen sessions were performed, each lasting 30 minutes, consisting of stretching of the flexor and extensor muscles of the wrist and elbow, pronators and supinators, followed by mirror therapy with gradual functional exercises. Results: Improvement was observed in all aspects studied, however with significant differences for ROM wrist extension (p = 0.04) and forearm supination (p = 0.03) Conclusion: It can be concluded that mirror therapy contributed to the participants' good performance in the aspects studied, mainly in relation to ROM of the affected upper limb.
