Hand surface area (HSA, cm2) was measured according to the method previously described by Lee et al. [9]. (HSA = 1.29 × circumference of the metacarpophalangeal joint × hand length.) Using the definitions of hand size presented by Pires et al. [10], the participants’ hand size was categorized as “small” (surface area ≤ 375 cm2), “medium” (surface area 376–424 cm2), or “large” (surface area ≥ 425 cm2). The size of the medical gloves each participant uses in daily practice (small/medium/large), which was referred to in the randomization process, and the dominant hand (right/left), was also recorded.
