Changes in Lower Limb Strength and Function Following Lumbar Spinal Mobilization.

Objective: The purpose of this study was to investigate whether grade III passive lumbar rotational mobilization on L2-3 can improve hip flexor strength and performance in the single-leg triple-hop test in asymptomatic young adults.

Methods: Twenty-four participants (12 men, 12 women) aged from 19 to 26 years who were positive in the hip flexor "break" test were recruited in this study. They were randomly allocated to the treatment group or sham group.

Sonographic evaluation of the effect of long-term exercise on Achilles tendon stiffness using shear wave elastography.

Objectives: This study aimed to assess the feasibility of using quantitative shear wave elastography (SWE) to assess the stiffness (Young's modulus) of Achilles tendon and to investigate the effect of long-term weight-bearing exercise on the stiffness of human Achilles tendon by comparing the frequent and infrequent exercise groups.

Design: Case-control study.

Methods: A total of 36 healthy subjects aged 19-25 were recruited.
