Cost-Effective Prosthetic Hand Controlled By Emg, Mohammad Yahya Almuhanna

Electronic Theses and Dissertations

A cost-effective five-finger prosthetic hand is designed from aluminum, modeled and controlled using surface Electromyography (EMG) signals, which are obtained from the human body. Force sensors are used to control required forces needed to grasp and pick objects. A prototype hand is developed and it is experimentally tested to reproduce a wide spectrum of human hand motions. The size of the five-finger hand is similar to an adult male human hand, and it is capable of reproducing most of movements. Each finger has the same number of links as the real/human hand. Each finger also has a force sensor used …

The Neuromuscular Response To Spinal Manipulation: Quantifying The Effect Of Pain With Electromyography, Stuart James Currie

Electronic Theses and Dissertations

Objective

To establish a methodology to quantify the neuromuscular response to spinal manipulation, develop a comprehensive date set including factors that affect the response, and compare the responses in both healthy participants and participants with acute and chronic low back pain.

Methods

Surface and indwelling electromyography at eight muscle locations were recorded during lumbar side-lying manipulations in 20 asymptomatic participants, 20 acute pain participants, and 20 chronic pain participants. Onset delay detection was optimized for signal detection failures and methodological comparisons were performed using a generalized linear model. The number of muscle responses and muscle activity onset delays in relation …
