The palapationmeter (or short PALM) is a reliable mechanical measuring device for the orthopaedic examination of patients by professions such as therapists, physicians and orthopaedic technicians. It measures the distance and angle between bony landmarks as they are palpated.
It's excellent reliability (see "studies") is achieved by the patented combination of palpating and measuring simultaneously. The palpating fingers assure accurate contact with the landmarks, while PALM gives objective readings of their relationship. If you remain in contact with the landmarks as the patient moves, you will live measure of mobility, ROM or movement related changes, eg to see how the iliac crest height changes in response to a weight shift.
