“…MGH is one of the institutions that make up Mthatha Hospital Complex which is a referral institution for the intRODuctiOn Stroke is one of the major causes of disability in the world (Ju et al 2007), and its long term effects require good adherence to physiotherapy sessions as an outpatient to ensure optimal rehabilitation. Patients are often left with residual effects of stroke as they are affected differently by the stroke attack (Mc Murdo 2008).…”

“…While several robotic and patient worn devices have been developed to quantify abnormal muscle tone [10]- [12], these systems can not be easily implemented into standard clinical practice. While there are a few hand held devices for the evaluation of abnormal tone [13] [14], they do not differentiate effects of manipulation speed or range of motion.…”

Neurological disorders such as cerebral palsy commonly result in abnormal muscle hyperactivity that negatively effects functional use of the affected limbs. Individuals with cerebral palsy often present with a mix of spasticity and dystonia, and it can be difficult to distinguish between the effects of these types of abnormal tone. Different types of abnormal tone respond differently to treatments such as deep brain stimulation and baclofen. Conventional clinical evaluation techniques provide minimal information for distinguishing abnormal tone characteristics and changes from treatment. Devices that quantify abnormal tone characteristics can help distinguish between the effects of different types of abnormal muscle tone, and help to quantify treatment effects. This paper discusses the development and initial evaluation of MyoSense(TM), a clinician worn device for the quantification and differentiation of abnormal muscle tone. MyoSense evaluates the orientation, speed, and force during clinician manipulation of the affected limbs with a protocol that is similar to conventional practice for evaluating abnormal tone. Evaluation of the MyoSense device, using a mechanical apparatus to simulate abnormal muscle tone, showed good resolution of abnormal tone characteristics. Using a procedure directly modeled after conventional clinical evaluation of abnormal tone, MyoSense data showed good correlation with simulated profiles, 0.8 for spasticity and 0.93 for hypertonia. Evaluation of average change across different limb manipulation speeds, to mitigate acceleration and mechanical effects, resulted in MyoSense data correlations to simulated profiles of 0.99 for spasticity, spasticity with a catch, and dystonia. Overall these results show promise for future clinical evaluation of the MyoSense device.

“…End-effector robots have practical advantages to work more proximal on the elbow and shoulder [2,3]. Especially, for the planar movement training of the proximal joints, five-bar linkage mechanism have been widely used because of its simple structure and lower control cost [2,5]. In the design of five-bar linkage structure for rehabilitation use, the determination of the actuators location and the joint configurations is crucial in order to improve the manipulability and workspace of the robot.…”

In the design of upper limb rehabilitation robots, critical issues to be considered are large workspace with minimum singularities to cover enough patients’ upper limb range of motion and higher manipulability for the patients to easily and freely move their arm with applying almost the same force to every direction in a given posture. This paper presents an analysis of the suggested kinematic design considerations of five-bar planar mechanism according to the actuator locations. A comparison between two different five-bar linkage types is given. Finally, several open challenges for the applicability of five-bar planar mechanisms are discussed from the kinematic point of view to upper limb rehabilitation robots.
