Universal precautions mandate that health care workers wear gloves when dealing with patients, often in situations requiring a high level of technical skill. Although it seems obvious that wearing the wrong size gloves could impair or prolong tasks involving manual dexterity, the issue has not been formally studied. We tested the hypothesis that wearing the wrong size gloves impairs manual dexterity. We administered a grooved pegboard test to 20 healthy, paid, volunteer health care workers. The subjects performed the test with bare hands and while wearing their preferred size of latex surgical gloves, gloves that were a full size smaller, and gloves that were a full size larger. Each subject did three runs with each size glove and three runs with bare hands. The time necessary to insert pegs was measured with a stopwatch. Peg insertion time was not affected by wearing preferred size gloves (vs. bare-handed) but was increased 7-10% by gloves that were either too small or too large (both effects: P < 0.05 vs. preferred size; both P < 0.001 vs. bare-handed). The subjects reported that the too-small gloves limited hand motion or hurt their hands, whereas the too-large gloves were clumsy but comfortable. Health care workers should wear gloves that fit properly when doing tasks that require manual dexterity. If the preferred size is unavailable, wearing gloves that are too large seems the best alternative.

ABSTRACT: The present study was conducted to review the literature on the methods that have been considered appropriate for evaluation of the effects of gloves on different aspects of hand performance, to make recommendations for the testing and assessment of gloves, and to identify where further research is needed to improve the evaluation protocols. Eighty-five papers meeting the criteria for inclusion were reviewed. Many studies show that gloves may have negative effects on manual dexterity, tactile sensitivity, handgrip strength, muscle activity and fatigue and comfort, while further research is needed to determine glove effects on pinch strength, forearm torque strength and range of finger and wrist movements. The review also highlights several methodological issues (including consideration of both task type and duration of glove use by workers, guidance on the selection and allocation of suitable glove(s) for particular tasks/jobs, and glove design features) that need to be considered in future research. Practitioner Summary: The relevant literature on the effects of protective gloves on different aspects of hand performance was reviewed to make recommendations for the testing and assessment of gloves, and to improve evaluation protocols. The review highlights research areas and methodological issues that need to be considered in future research.

ABSTRACT: This study was performed to determine the changes in electromyographic activities in the shoulder and forearm muscles when using the bare hands, well-fitting gloves, and gloves that are one size smaller or one size larger for simulated assembly operations. Sixteen asymptomatic seated workers with normal hands and no obvious deformities, skin diseases, or allergies were recruited. The subjects were asked to simulate assembly operations using their bare hands, well-fitting gloves, and one size smaller or one size larger. This study showed that wearing the wrong glove size led to a decrease in forceful activation of the forearm muscle and a compensatory increase in shoulder movement. In contrast, use of the bare hands or wearing well-fitting gloves led to effective forearm muscle activation, which decreased inefficient shoulder movement. These data indicate that wearing the wrong glove size will lead to continuous inefficient use of the forearm and shoulder muscles, and result in overuse of the shoulder.
