The Overhead Squat: an Assessment Tool

Almost everyone needs to squat or lower their center of gravity in their daily life. The overhead squat is becoming a popular dynamic assessment tool for the Personal Trainer to assess a client's integrated functional strength, flexibility and neuromuscular efficiency. The overhead squat is a valid assessment tool to observe any compensatory movement patterns. Any alteration in muscular recruitment could be a result of decreased range of motion, instability or weakness.
This is a macro assessment. The overhead squat provides an overall impression of how all joints interact with one another. Any compensations or faulty movement patterns may suggest a weak link. A weak link may mean many different things. It's up to you to perform more specific assessments (see goniometer assessments) in order to implement an exercise program.
Here's what you will need to perform this simple assessment:
$ 3 ft. dowel rod or a broom stick
$ Assessment sheet
This is how you administer the assessment:
$ Ideally, the client should be barefoot, wearing shorts and t-shirt. Don't give them too many instructions so they'll move naturally.
$ Have the client place their feet straight ahead at about shoulder width. Their feet should be perfectly straight, this is very important. Ensure the foot and ankle is in a neutral position.
$ Have the client hold the dowel rod or stick above their head. Their arms are fully extended over their head in maximal shoulder flexion so their biceps are at ear level.
$ Have the client perform an anterior and posterior pelvic tilt to find their neutral position.
$ Have the client squat down as if they were sitting in a chair.
1. Have the client perform a few repetitions. Don't burn them out. Assess them from the front or stand next to the client and watch them in the mirror. Note on your assessment sheet any compensations.
2. Have your client perform a few more repetitions and observe them from one side, then the other side. Note any compensations on your sheet. Now observe them from behind.
Here is a guide to help you assess the overhead squat.
