Abstract
[Purpose] In this study, wall squats were performed with the buttocks, outside of the legs and 5th metatarsals in contact with a custom-built nook with an adjustable corner angle. The subjects who made movements to depart from this squatting position were judged the wall-squat abnormal (WSA) group. The study was performed to clarify whether the characteristics of WSA from WS with nook angles of 50 and 70° took the same form as those of 90°. [Subjects and Methods] The subjects were 50 males and 50 females (mean age: 21.7 ± 3.7 years). The form of their WS at nook angles of 50, 70 and 90° were evaluated. [Results] Subjects judged to have WSA in 90°WS were judged to have the same tendencies of WSA in 50° and 70°WS. [Conclusion] There is a possibility that mechanical stresses occur in knee flexion movements of WSA subjects, even in daily living activities.
