Measuring intrinsic hip external rotator strength (ER) without compensatory pelvic motion and activation of the sartorius is important for preventing or rehabilitating lower extremity injuries. However, the optimal method for measuring intrinsic hip ER muscle strength while minimizing compensatory pelvic motions and activation of the sartorius is unclear. The purpose of this study is to compare measurements of hip ER strength, compensatory pelvic motion, and sartorius activation in the sitting, prone, and sidelying positions. Thirty-one healthy subjects (16 males and 15 females) were recruited for this study. Hip ER strength, pelvic kinematics, and sartorius muscle activation were measured during maximal isometric contraction of the hip ER in the sitting, prone, and sidelying positions. Hip ER strength was measured using a load-cell-type strength-measurement sensor. Pelvic kinematics was measured using an electromagnetic motion-tracking sensor. Electromyography was used to measure sartorius muscle activity. Data were analyzed using one-way repeated-measures analysis of variance. The result showed that hip ER strength and sartorius muscle activation were significantly lower in the sidelying compared with the sitting and prone positions (p < 0.01). Pelvic anteroposterior tilting was significantly greater in the sitting compared with the prone and sidelying positions (p < 0.01). Pelvic rotation differed significantly among positions (p < 0.01). Pelvic lateral tilting was significantly greater in the prone compared with the sitting position (p < 0.017). Compensatory pelvic motion and sartorius muscle activation were lower when hip ER strength measurements were made in the sidelying position. Therefore, the sidelying position is effective for measuring selective intrinsic hip ER strength.

Background: Softball pitching is a ballistic, complex movement that requires an underhand windmill motion to create force and ball velocity. In addition to proper pitch biomechanics, upper and lower extremity strength and joint motion likely contribute to ball location accuracy and velocity. Yet, the number of studies reporting muscle strength and joint range of motion among softball pitchers is scarce.Objective: To assess differences between throwing and nonthrowing shoulder, elbow, and hip (lead and trail leg) strength and range of motion (ROM) in high school and collegiate level softball windmill pitchers. Design: Cross-sectional study. Participants: Thirty-three female softball pitchers (24 high school, 9 collegiate) were recruited from local teams. Methods: Goniometric joint ROM and handheld dynamometer strength measurements of the bilateral shoulders, elbows, and hips were measured. Main Outcome Measurements: Goniometric joint ROM of the bilateral elbows (flexion, extension), shoulders, and hips (flexion, extension, internal rotation [IR], external rotation [ER]). Handheld dynamometer strength measurements of the bilateral shoulders (flexion, extension, abduction, IR, ER), elbows (flexion, extension), and hips (flexion, extension, IR, ER, abduction). Results: Across all pitchers, there was greater shoulder flexion ROM in the nonthrowing limb than in the throwing limb (P = .004). There was greater hip extension in the lead leg than trail leg. Among high school pitchers, there was greater shoulder ER (x = 105.792 AE 7.11) than collegiate pitchers (x = 100.1 AE 6.92), P = .05. There was no difference in total arc of shoulder rotational motion (ER+ IR) between throwing and nonthrowing limbs across all pitchers, nor between high school and collegiate pitchers. Strength measures demonstrated greater throwing limb shoulder abduction (P = .006) and IR strength (P = .001) than the nonthrowing shoulder across all pitchers. Elbow flexion strength was significantly greater than the nonthrowing side (P = .001). No difference was noted in hip strength between lead and trail lower extremities. Conclusions: Developing normative data for softball pitchers upper and lower extremity strength and range of motion may allow providers to assess players more comprehensively and identify athletes out of the expected value range. This information may help in guiding strength and conditioning programs for softball pitchers.
