Limitation of ankle motion is in many cases treated by joint mobilization (JM), a kind of manual physical therapy technique. Until now, the JM approach has mainly focused on the talocrural joint, with less attention to the distal tibiofibular joint. We applied cyclic loading to the lateral malleolus as in JM in order to clarify the relationship between the(More)
BACKGROUND Contracture of the coracohumeral ligament is reported to restrict external rotation of the shoulder with arm at the side and restrict posterior-inferior shift of the humeral head. The contracture is supposed to restrict range of motion of the glenohumeral joint. METHODS To obtain stretching position of the coracohumeral ligament, strain on the(More)
[Purpose] To clarify rotator cuff muscular activity in the raised position of the closed kinetic chain (CKC) exercise. [Subjects] Twenty-nine cases were studied, 19 men and 10 women (average age 21.5 ±4.7 years old, average body weight 60.1 kg ±11.4). [Methods] To determine the effects of the closed kinetic chain exercise on the upper limb, we measured the(More)
The purpose of this study was to determine the most effective elbow joint flexion angle for mobilization of the proximal radio-ulnar joint. Five fresh-frozen cadaveric elbows were used to measure displacement of the radial head in the antero-medial and postero-lateral directions by traction force of 2kgf and 4kgf, respectively. Simulation of the gliding of(More)
The stylopharyngeus plays a critical role in the clearance of the piriform recess. We dissected 78 sides of the pharynx from 55 donated cadavers and observed histology of another seven sides of the pharynx from seven cadavers. The stylopharyngeus consistently comprised (1) a descending muscle bundle surrounding the piriform recess and (2) an additional(More)
