Abstract
Dental professionals are at the high risk of fatigue in upper quadrant area. Hence, this study aims at assessment of the muscle behaviour of dentists during isotonic postures while performing various dental procedures. Twenty dentists participated in the study. Assessment of hand parameters like grip, pinch strength and dexterity was done in the beginning and end of work day. Development of muscle fatigue was assessed by surface electromyography of two forearm muscles i.e. Flexor Carpi Ulnaris (FCU) and Extensor Carpi Radialis Longus (ECRL). Statistics done by spectral analysis (median frequency). It was found that the median frequency decreased significantly in the forearm muscle. Hand function namely, grip (P < 0.0001), pinch (P < 0.0001), dexterity (p < 0.0001) has also shown significant decline over a period of time. Study conclude that overuse of forearm muscle work had influenced hand function significantly.
