O estudo foi desenvolvido no per\u00edodo de outubro de 2017 a abril 2018. A amostra foi formada por volunt\u00e1rios sem hist\u00f3rico de trauma, cirurgia ou qualquer afec\u00e7\u00e3o dos membros superiores. Foram inclu\u00eddos neste estudo indiv\u00edduos de ambos os g\u00eaneros com idade igual ou superior a 18 anos. A avalia\u00e7\u00e3o da fun\u00e7\u00e3o do tend\u00e3o do m\u00faculo flexor superficial do quarto e quinto dedos foi realizada por meio de testes cl\u00ednicos por tr\u00eas examinadores independentes.

A preval\u00eancia da aus\u00eancia de fun\u00e7\u00e3o do tend\u00e3o do m\u00fasculo flexor superficial do quarto dedo foi de 0,56% na m\u00e3o direita e 0,99% na m\u00e3o esquerda. Em rela\u00e7\u00e3o ao g\u00eanero, foi verificado na m\u00e3o direita uma maior preval\u00eancia da aus\u00eancia de fun\u00e7\u00e3o do flexor superficial do quarto dedo no g\u00eanero feminino quando comparado ao masculino (p\u2009=\u20090,0328). Na m\u00e3o esquerda n\u00e3o foi observada diferen\u00e7a entre os g\u00eaneros (p\u2009=\u20090,7562). A aus\u00eancia de fun\u00e7\u00e3o do m\u00fasculo flexor superficial no quinto dedo foi de 34,53% na m\u00e3o direita e de 30,06% na m\u00e3o esquerda. Quando analisamos o quinto dedo em rela\u00e7\u00e3o aos g\u00eaneros, foi verificado que a preval\u00eancia da aus\u00eancia de fun\u00e7\u00e3o do m\u00fasculo flexor superficial foi mais frequente
