Longitudinal Observation of Myoelectric Upper Limb Orthosis Use Among Veterans With Upper Limb Impairment
In Brief
A clinical study evaluating MyoPro Motion-G and Motor Learning-Based Therapy for Traumatic Brain Injury and Stroke. Completed, enrolled 16 participants across 1 site.
Detailed Summary
The objective of this study was to document longitudinal outcomes in persons with traumatic brain injury (TBI) or stroke using the myoelectric upper limb orthosis with powered elbow and grasp in conjunction with motor learning-based therapy using both patient centric performance and patient reported outcome measures. Longitudinal observation allowed the investigators to detect both the initial therapeutic effects as well as the later functional outcomes of orthosis use. The investigators planned to recruit 15 Veterans and non-veterans who had TBI or stroke and upper limb impairment. The study required 29 visits over 22 weeks and was divided into three parts: orthotic fitting, therapy/training (9 weeks), and home use (9 weeks). Therapeutic and functional benefits were evaluated every 2 to 3 weeks over 18 weeks using simple, short clinical tests.

Timeline
Interventions
The MyoPro Motion-G is an elbow-wrist-hand myoelectric orthosis.
Motor learning-based (MLB) therapy included movement practice as close to normal as possible, high repetition, progression of challenge, part versus whole task practice, and knowledge of results. Treatment was customized to abilities of each subject and consisted of both MyoPro training and MLB therapy without device. Training with device was progressed using a hierarchy of challenge to increase complexity of movement. MLB therapy without device followed the same hierarchy, incorporating training of movements that could not be accomplished with the device and those that were trained with device. Movement quality was monitored and training practice was incrementally progressed as subject demonstrated improved ability to perform a given task/movement component. Subjects performed a custom home exercise program (HEP) on non-clinic days, increasing repetition as tolerated. At conclusion of in-clinic phase, individuals transitioned to a home phase where they continued to use the HEP.
