• Resumen

  • OBJECTIVE. Our objectives were (1) to quantify arm�hand use of older adults without a disability and to determine the effects of hand dominance, gender, and day on hand usage and (2) to determine the factors that predict arm�hand use. This information will enhance understanding of the extent of the client�s occupational performance.

    METHOD. Twenty men and 20 women, ages 65�85, wore wrist and hip accelerometers for 7 consecutive days. Manual dexterity and grip strength were assessed. A three-way factorial analysis of variance and multiple linear regressions were conducted.

    RESULTS. The activity kilocounts from both wrist accelerometers revealed a significant interaction effect between hand and gender (F[1, 190] = 24.4, p < .001). Enhanced manual dexterity of the right hand was associated with greater right-hand use.

    CONCLUSION. Arm�hand use is a novel dimension of hand function measuring the extent of real-life occupational performance in the client�s home
