Normalization of EMG signals: to normalize or not to normalize and what to normalize to
Electromyography (EMG) has been around since the 1600s [1]. It is a tool used to measure
the action potentials of motor units in muscles [2]. The EMG electrodes are like little …

Superior humeral head migration occurs after a protocol designed to fatigue the rotator cuff: a radiographic analysis
JN Chopp, JM O'Neill, K Hurley… - Journal of shoulder and …, 2010 - Elsevier
HYPOTHESIS: Awkward postures and repetitive work have been suggested to lead to
shoulder fatigue, which may in turn decrease the subacromial space. The aim of this study …
