Description
Full or partial loss of function in the shoulder, elbow or wrist are a common impairment in the elderly, but can also be a secondary effect due to strokes, sports injuries, trauma, occupational injuries, and spinal cord injuries. This functionality of the upper extremity (UE) is essential to perform activities that contribute to one’s independence and quality of life, also known as the activities of daily living (ADL). The purpose of this experiment is to analyze the kinematics and the muscle activities of human UE while performing a variety of ADL. In this pilot study, Avanti EMG electrodes (Delsys Inc.) were used to collect the EMG signals and the kinematic data (joint angle of rotation, velocity, acceleration) from 10 healthy individuals. For each ADL task, the kinematic data and the corresponding EMG activity of muscles were compared to find a relation between the specific ADL with joint kinematics and EMG signals. Future studies will include performing experiments with more healthy individuals and with the subjects suffering from reduced UE function. Ultimately, this data lays a foundation that enables engineers, physicians and occupational therapists to more fully understand patients’ injuries and coordinate to effectively developed diagnostic and rehabilitation methods.
