The Use Of Audio Stimulation To Affect Sensorimotor Learning, Gregory Nicholas Ranky

Dissertations

Sensorimotor learning for the hand and fingers can be conducted using both hardware and software components, but the training regime is also important. Using repetitive sequence tapping allows measurement of defined metrics in a controlled, safe environment, and therefore statistical indications for subject improvement.

The process of entrainment, when a subject’s own movements synchronize to an external signal, has been tested in prior studies for memorization and recognition, but has not been investigated for correlation with sensorimotor learning.

This is tested with selected custom isochronic audio tones, combined with sequential finger tapping on a standard computer keyboard.

A Novel Approach To Increase Upper Extremity Active Range Of Motion For Individuals With Duchenne Muscular Dystrophy Using Admittance Control, Madeline Catherine Corrigan

Dissertations

Duchenne muscular dystrophy (DMD), a neuromuscular disease with a prevalence of 1 in 3,500-5,000 male births, results in progressive muscle weakness causing loss of independence and imposing the demands of costly and intrusive assistive support and personal care for daily living tasks. Upper extremity function begins to decline while ambulation is still possible and gradually progresses with time, playing a prominent role in loss of independence. Importantly, upper extremity functional limitations exist despite residual muscle strength that is insufficient to lift the arms against gravity. Presently, there exist a number of commercially available assistive devices aimed at augmenting upper extremity …
