Article Synopsis
  • The study investigates how abdominal oblique strength affects the biomechanics of pitching in adolescent baseball pitchers.
  • Involving nineteen healthy right-handed male pitchers, it uses motion capture technology to analyze key pitching mechanics and the relationship with oblique strength.
  • Results show that stronger abdominal obliques correlate with increased pelvis and torso rotation velocity, suggesting that strengthening these muscles could enhance pitching performance.

Background: Gait retraining can be effective in altering lower extremity biomechanics and reducing risk of injury. In attempts to alter running gait, previous studies used metronomes to manipulate cadence.

Research Question: The aim of this study was to determine if manipulating running cadence via music could alter lower extremity biomechanics.

Context: Inadequate hip active range of motion (AROM) may stifle the energy flow through the kinematic chain and decrease pitching performance while increasing the risk for pitcher injury.

Objective: To examine the relationship between hip AROM and pitching biomechanics during a fastball pitch in adolescent baseball pitchers.

Design: Cross-sectional study.

Background: The purpose of the current study was to determine sagittal plane talocrural and subtalar kinematic differences between barefoot and controlled ankle movement (CAM) boot walking. This study used fluoroscopic images to determine talar motion relative to tibia and calcaneal motion relative to talus.

Methods: Fourteen male subjects (mean age 24.

The purpose of this study was to quantify the accuracy and precision of a biplane fluoroscopy system for model-based tracking of in vivo hindfoot motion during over-ground gait. Gait was simulated by manually manipulating a cadaver foot specimen through a biplane fluoroscopy system attached to a walkway. Three 1.

Biplane fluoroscopy is used for dynamic in vivo three-dimensional motion analysis of various joints of the body. Cross-scatter between the two fluoroscopy systems may limit tracking accuracy. This study measured the magnitude and effects of cross-scatter in biplane fluoroscopic images.
