Study Details

This study aims to evaluate the feasibility and reliability of a novel method for assessing finger extension strength using an adapted dynamometer, addressing the limitation of current hand grasp assessment protocols that focus only on finger flexor muscles. The study will recruit able-bodied adult participants, and a force gauge will be used to obtain precise measures of the strength of their extensor digitorum muscles. Participants will be seated with their upper extremity supported on an adjustable table and have a force gauge, connected to a custom-made support positioned around their proximal phalanx. The support will be connected to a force gauge, which will measure participants' extensor muscles strength in Newtons (N). To assess the feasibility and reliability of this new setup, three measurements will be collected for each hand, with a one-minute interval between each measurement and a 5-minute break between evaluators, with the order randomized to reduce bias. The study will recruit participants from BU's Sargent College of Health and Rehabilitation Sciences and will be conducted by independent evaluators trained in muscle assessment and clinical evaluation of the hand and upper extremities. The total participation time should not exceed 30 minutes per participant. The primary hypothesis is that this novel and accessible device can provide accurate and reliable measurements of participants' finger extensor muscles' strength. Results from this study could have important implications for hand rehabilitation and therapy, particularly for individuals with hand dysfunction due to musculoskeletal disorders or injuries.
