Investigation of the Use of Manual Muscle Testing in Occupational Therapy

Abstract

Undergraduate occupational therapy students learn the theory and mechanics of functional strength assessment and manual muscle testing in order to measure the effectiveness of their physical treatments and to ascertain the functional level of their patients. However, it is important to determine how practicing therapists are actually assessing strength. This information would help both in directing curriculum teaching efforts at the undergraduate level and in assessing the needs of the profession in the use of clinical strength measurement systems. The present study sought to determine the therapy areas and extent of use of functional and manual muscle tests by occupational therapists across Canada. Information was also gained about the factors related to the use of manual muscle testing by practicing clinicians. The results of the survey indicated that occupational therapists do use manual muscle testing, but to a lesser extent than functional assessments. A large number of therapists stated they relied on other co-workers, such as physical therapists, to perform manual muscle tests on their patients. Though they did not perform the manual muscle tests themselves, occupational therapists thought that occupational therapy students should have a thorough knowledge of manual muscle testing in order to work effectively as a team member in the clinic. The study also found that University of Manitoba graduates used manual muscle testing with the greatest percentage of their patients than any of the other Canadian graduates surveyed. Of interest is the finding that manual muscle testing use increased when instruction occurred on the job in addition to the University teaching of the skill.
