Resumen The objective of this study was to analyze the levels of forearm muscular contraction associated with the use of anti-vibration gloves. Two vibrating tools (multi-cutter and rotary hammer) were used in a simulated work environment. Standard operations were performed by each of the 14 subjects using the two tools. Forearm muscular efforts were measured by surface electromyography (EMG) in four muscles: flexor digitorum superficialis (FDS), flexor carpi ulnaris (FCU), extensor carpi radialis longus (ECRL) and extensor carpi ulnaris (ECU). For the flexor muscles (FDS and FCU), a decrease tendency in the measured EMG was observed when the operations are performed with gloves relative to the bare hand (a reduction of 5-23% in the percentage of maximum voluntary exertion (%MVE)). For the extensor muscles (ECU), a tendency toward increased muscular contraction was observed when the operations were performed with gloves (an increase of 3-20% in the %MVE). No such tendency was found in the ECRL muscle. It is concluded that anti-vibration gloves may increase forearm fatigue in the posterior forearm (ECU muscle) and decrease forearm fatigue in the FDS muscle during operations with the vibrating tools.
