Evaluation of the force created in the biceps brachii muscle by simulating the forearm bending movement during dynamic movement

Gripping is an important hand function required for successful daily living activities. Grip strength measurements are one of the regional strength assessment methods and are used as the basic element in the evaluation of arm function. The scope of this study is to analyze biceps brachii muscle strength levels by taking noninvasive muscle strength measurements from individuals. The biceps brachii muscle plays an important role in upper body movements. There are various studies in the literature on measuring the electromyography (EMG) signal and muscle strength of the Biceps Brachii muscle during arm wrestling movement, but no study has been found on measuring biceps muscle strength during a movement similar to arm wrestling movement, in other words, during dynamic movement, with a hand dynomometer. The aim of this master's thesis is to measure the electrical currents produced during the contraction of the Biceps muscle during dynamic movement with the Electromyography (EMG) device and to find a proportional relationship with muscle strength. By taking into account the force values obtained from the EMG signal in line with the analyzes performed at the end of the study, it was possible to determine whether individuals' cumulative trauma disorders (CTD) and various muscle diseases (paralysis, multiple sclerosis, etc.) are a risky situation for the biceps brachii muscle. This framework reveals a promising potential in the design of prosthetics and orthoses, in the evaluation of rehabilitation processes, and in improving the quality of life of individuals struggling with movement and coordination disorders in the studied muscle.
