In physical therapy and rehabilitation, the feeling experienced by an evaluator when overpressure is applied to tissue at the end of the available range of motion. It is interpreted as abnormal when the quality of the feel is different from normal response at that joint. The feeling may be soft as when two muscle groups are compressed or soft tissues are stretched, firm as when a normal joint or ligament is stretched, or hard as when two bones block motion. Abnormal end feels may include a springy sensation when cartilage is tom within a joint, muscle guarding when a muscle involuntarily responds to acute pain, or muscle spasticity when there is increased tone due to an upper motor neuron lesion or when the feeling is different from that normally experienced for the joint being tested.
