Test Positioning: ROM & MMT

     As an OT, it is imperative that you use bony landmarks and proper positioning when measuring a clients range of motion (ROM). By finding the bony landmarks, it ensures the therapist has the correct placement of the axis, stationary arm and moveable arm on the goniometer to get a precise and accurate reading. The correct placement is also important because with every therapist using the same landmarks and positions the inter-rater reliability will be higher and it will not become an issue if different therapists work with a client. Palpating bony landmarks will also identify any bony or soft tissue irregularities. Along with correct placement of the goniometer, proper positioning of the client is important to ensure that the client is in a comfortable position that allows for full ROM of the joint being measured. This will allow for the most accurate and precise measurements.
     When working with manual muscle testing (MMT), the "test position" is also a very important component. An optimal test position would be in mid-range position of the movement which is where the highest number of cross-bridges are formed and the ideal length-tension relationship is. Another component of MMT is a testing positioned that is gravity eliminated. This is when the client can not resist the force of gravity so the position of the client will be moved so that the movement is done parallel to the ground. With client being in a gravity eliminated position, it allows the therapist to be able to palpate small muscle contractions that may be happening.
