Certified Hand Therapist (CHT) Practice Exam

A hand dynamometer is commonly used to evaluate grip strength because it provides a quantitative measure of the force exerted by a person's grip. This device allows for consistent and repeatable measurements, which are essential for assessing changes in strength over time or comparing grip strength between individuals. The results can help therapists determine the functional capabilities of the hand and design appropriate rehabilitation programs.

In contrast, a visual analog scale is primarily used to assess pain levels rather than grip strength, while a range of motion goniometer measures joint angles, which is not directly related to grip strength. Physical examinations, although useful for a variety of assessments, typically lack the specificity and objectivity that a hand dynamometer offers for evaluating grip strength specifically.
