Ipsilateral Electromyographic Activity Of Shoulder Muscles During Unilateral Maximal Resistance Of Grasp In The Prone-On-Elbows Position, Bryan John Wodaski

Masters Theses

This study reports the relationship between electrical output of the deltoid muscle and the pectoral is major muscle (clavicular portion) ipsilaterally, following maximal resistance to grasp of the non-dominant hand while in the prone-on-elbows position. Forty-two normal college students were recruited from Western Michigan University, Kalamazoo, and were randomly assigned to experimental and control groups. The experimental subjects' shoulder muscles' electrical activity was measured for changes from baseline to maximal contraction during two trials. The control group was measured in the same manner but they were not asked to contract their hand against resistance. For both groups electrical activity was …
