capsule exhibits fewer parallel fibers and is composed of different types of collagen. It is more elastic than the ligaments. The principle of collecting, documenting, and interpreting the signs and symptoms is exactly the same as for the passive compression tests. Pain within the joint capsule occurs only with inflammatory changes and is transmitted to the central nervous system by type-IV receptors (Wyke 1972, 1979; Clark and Wyke 1974). Various neuropeptides such as NA and SP effect the release of prostaglandins, which in turn elevate the sensitivity of the pain receptors (Levine et al. 1986, Lotz et al. 1987).
