Test Postitioning- Blog 2 Biomechanics

Using specific protocols during testing is important for making consistent measurements that align with evidence.  By positioning our clients properly and measuring the joint using the bony landmarks to measure active range of motion, as provided by our protocols, we can more efficiently and precisely determine if our clients are inside or outside norms of range of motion. When our clients are unable to perform active range of motion with gravity, we will use a gravity eliminated postion, where the motion is performed parallel to the ground. This will help to determine if the muscle is functional, and if so, how much range of motion the client is able to perform at that joint without the resistance of gravity. When our client is able to perform active range of motion with gravity, it is appropiate for us to perform maual muscle testing (MMT), which tests the amount of resistance the joint can withstand. During MMT, it is pertinant that the client is in the propper test position so that they are able to perform at their maximum capicity; mucles are able to create the most number of crossbridges when positioned at half the client's normal range of motion. By determining our client's range of motion and ability to resist gravity and the strength of the therapist, the practitioner is able to determine strengths, weaknesses, and compensatory movements of their clients. This will help OT practitioners make attainable goals for our clients with interventions and percautions that reflect the functional ability of the client. Additionally, we will be able to reevaluate our clients after they have participated in OT to see if they have made progress and what steps they need to make for future treatment.
