Preventing Rsi/Wruld: use of esthesiometry to assess hand tactile sensitivity of slaughterhouse workers.
This research was conducted with slaughterhouse female workers in the municipality of São Miguel do Iguaçu, state of Parana, Brazil. The sample was composed of 103 women aged 25 to 40 ( 7.57 years, and the study aimed to verify the nerve conduction of the median nerve. An esthesiometer consisting of a Semmes-Weinstein monofilaments was used to measure the hand skin sensitivity in the region of the median nerve and a Jamar® hand dynamometer, which was used to determine the handgrip strength. About 81% of individuals had normal sensitivity with 0.05 g and average levels of handgrip strength in dominant hand (DH) of 35.30 kgf (( 3.10) and in the non-dominant hand (NDH) of 28.30 ( 3.09 kgf. 14% of individuals had reduced sensitivity, with values equivalent to 0.2 g and 2.0 g (blue and violet) and levels of handgrip strength in the DH equal to 28.10 kgf (( 2.90) and in the NDH of 26.40 kgf (( 3.28). 5% of individuals showed bilateral sensitivity deficit (4.0 g) and levels of handgrip strength in the DH of 16.10 kgf (( 2.10) and in the NDH of 18.20 kgf (( 3.28), resulting in a strong correlation between handgrip strength and sensitivity of the median nerve (r = 0.786) between variables dominant hand (DH) and (r = 0.626) for the non-dominant hand (NDH). It could be concluded that assessing the nerve conduction of the median nerve by hand esthesiometry can be an important tool in preventing the Carpal Tunnel Syndrome.
