Assessment of Grip Strength, Lateral Pinch Strength and Three Point Pinch Strength Measurement Using BTE Work Simulator and Jamar Dynamometer in Normal Adults

Abstract

Recently, increased emphasis has been placed on the need for rehabilitation professionals to objectively evaluate a patient's potential for a return to normal function. But, as the medical recovery nears completion, additional questions are commonly asked by physicians regarding work function and ability to return to full active employment. In the past, therapists have attempted to reestablish the work situation using real tools, however, these machines are expensive, spaces are limited, and it is potentially dangerous as well in some cases. A BTE (Baltimore Therapeutic Equipment) Work Simulator overcomes these shortcomings. It can be used for isometric and isotonic evaluation and treatment, it also assists in providing information needed to make determinations on the progress in therapy, return-to-work status and job modifications. We planned to obtain data on normative isometric, dynamic strength and endurance of grip, lateral pinch and three point pinch using BTE Work Simulator model WS20 and to compare these data with Jamar Dynamometers set which measure only isometric strength. We also compared these data between ages and sexes. This study will be helpful in clinical applications of the BTE Work Simulator in providing more specific job-related occupational therapy and developing special vocational rehabilitation program.
