Background: Stretching and length test of hamstring muscles have been performed commonly to manage lower back pain (LBP) in sports rehabilitation. Previous literatures addressed that stretching techniques and length test of hamstring muscles should be performed with the pelvic maintained in an anterior tilt position. However, there is no study to determine the effectiveness of pressure biofeedback unit (PBU) to maintain in anterior pelvic tilting (APT) on length test and stretching of hamstring muscles.

Study Design: Randomized control trial.

Introduction: During weight-bearing wrist movement, potential stabilizing forces caused by carpal stabilizing taping (CST) may restrict movement of the carpal bones, allowing greater wrist joint extension.

Purpose Of The Study: The purpose of study was to investigate the effect of CST during weight-bearing wrist movement on pain intensity and range of motion (ROM) of wrist extension in subjects with dorsal wrist pain.

Head and neck paragangliomas are rare neuroendocrine tumors that arise from paraganglion cells of the parasympathetic nervous system. Paragangliomas arising from the midline skull base have only rarely been reported. Surgery is the mainstay of treatment and adjuvant radiation is often recommended.

Objectives: This study was conducted in order to determine the effect of feedback tools on activities of the gluteus maximus (Gmax) and oblique abdominal muscles and the angle of pelvic rotation during clam exercise (CE).

Design: Comparative study using repeated measures.

Setting: University laboratory.

Objective: To prevent overuse injuries related to excessively pronated feet, the strengthening of the foot intrinsic muscles has been recommended. The purpose of this study was to examine the effects of foot orthoses and a short-foot exercise intervention on the cross-sectional area (CSA) of the abductor hallucis (AbdH) muscle and strength of the flexor hallucis (FH) in subjects with pes planus.

Methods: Twenty-eight subjects with pes planus were randomly assigned to the foot orthosis (FO) group or the combined foot orthosis and short-foot exercise (FOSF) group for an 8-week intervention.

Objective: To compare the muscle activity of the abductor hallucis (AbdH) and the medial longitudinal arch (MLA) angle during toe curl (TC) and short foot (SF) exercises while sitting or in one-leg standing position.

Design: Two-way repeated-measures ANOVA was used to analyze the effects of exercise type and position on the muscle activity of the AbdH and the MLA angle.

Participants: Twenty subjects with normal feet participated in this study.

Study Design: Controlled laboratory study.

Objectives: To examine the effects of standing wall stretching with and without medial arch support (WMAS versus WOMAS) on the displacement of the myotendinous junction (DMTJ) of the medial gastrocnemius, rearfoot angle, and navicular height in subjects with neutral foot alignment and pes planus.

Background: Standing wall stretching is often prescribed to increase ankle dorsiflexion range of motion for sports fitness and rehabilitation.
