Extensor Tendon Injury
An Occupational Therapy Perspective
Assessment of Motor Performance
There are various standardized assessments used to measure hand performance. These assessments measure general hand function, and do not specifically focus on extensor tendons; however, both flexor and extensor tendons must work in harmony and an injury to either tendons will interfere with functional hand dexterity. Kuran (2014) writes that “tendon lacerations adversely affect normal hand function by disrupting the synergy between extension and flexion of the hand” (p.94).
The following are a few standardized, norm based assessments that can be implemented to assess the functional hand performance of Felix:
-Jebsen-Taylor Hand Function Test
-Box and Block Test
-Sollerman Hand Function Test
-Crawford Small Parts Dexterity Test
Non standardized assessments can also be used in this case. As keyboarding is a requirement of his job, the occupational therapist could observe Felix’s performance while he types. Returning to work is a primary goal for Felix; therefore, assessing functional performance on specific workplace tasks is important.
