Comparing two methods to record maximal voluntary contractions and different electrode positions in recordings of forearm extensor muscle activity : Refining risk assessments for work-related wrist disorders
BACKGROUND: Wrist disorders are common in force demanding industrial repetitive work. Visual assessment of force demands have a low reliability, instead surface electromyography (EMG) may be used as part of a risk assessment for work-related wrist disorders. For normalization of EMG recordings, a power grip (hand grip) is often used as maximal voluntary contraction (MVC) of the forearm extensor mu
