Divergence from the Normative Gait-Development Trajectory: A Multidomain Model of Gait Divergence in Hemiplegic (Unilateral) and Diplegic (Bilateral) Spastic Cerebral Palsy
Background/Objective: Gait symmetry in children is increasingly understood as a development-dependent continuum rather than a fixed endpoint. This narrative review extends that framework into a multidomain model of gait divergence in cerebral palsy (CP), asking whether asymmetry in hemiplegic and…

From Rest or Recoil: Comparing Squat and Countermovement Techniques for Maximum-Height Jumping Using Musculoskeletal Simulation and Dynamic Optimization—A Computational Study
Background: The countermovement jump (CMJ) and the squat jump (SJ) are two common techniques for maximum-height jumping. The CMJ typically produces a greater jump height than the SJ; however, the mechanisms responsible for this difference in performance and the roles that musculotendon dynamics…

In-Line Power Screwdrivers Recoil: A Pilot Computational Methodology to Assess Differences Among Workstations from a Human-Centric Perspective
Background/Objectives: Mechanical shocks generated by the recoil of hand-held power screwdrivers are a significant biomechanical stressor for the operator’s hand–arm complex. Currently, vibration exposure is measured at the tool-handle level, while operator-centered practical measures remain…

Biomechanical Evidence for the Proactive Balance Strategy as a Functional Analogue of the Ankle Strategy During Stationary Manual Wheelchair Wheelies
Background/Objectives: Maintaining a stationary manual wheelchair wheelie is a highly demanding dynamic postural control task that can be biomechanically modeled as an inverted pendulum. Although skilled wheelchair users employ a Proactive Balance Strategy (PBS) characterized by small rhythmic…

Three-Dimensional Kinematic Comparison of Spoon and Chopstick Use During Ingestion
Background/Objectives: Human feeding behavior involves the use of various tools. However, the kinematic differences between commonly used utensils such as spoons and chopsticks remain insufficiently understood. The current study aimed to quantitatively characterize and compare the three-dimensional…

Realistic Boundary Conditions in Testing Diaphyseal Femoral Implants
Background: Considerable variation exists in the proximal and distal fixture designs used in biomechanical testing of diaphyseal femoral implants. In most of them a load is applied to the femoral head, but muscle forces are rarely represented, so bending of the diaphysis is unphysiologically high…

Effect of Sitting Posture on Transversus Abdominis Thickness and Trunk Muscle Activity During a Valsalva-Based Simulated Straining Task in Healthy Young Adults
Background/Objectives: Defecatory straining requires coordinated abdominal-wall and lumbopelvic muscle activity to generate propulsive pressure. This study investigated whether sitting posture alters ultrasound-derived transversus abdominis (TrA) contractile behavior and trunk surface…

A Human Shoulder Simulator for Cyclic Evaluation of Rotator Cuff Injury and Repair
Background/Objectives: Surgical repair of the rotator cuff tendons can lead to unsatisfactory results and the requirement for further surgical treatment. Development of repair techniques is limited by a lack of appropriate functional pre-clinical testing, especially over extended motion cycles. The…
