Purpose: To examine the effect of a sequential fatigue protocol on lower extremity biomechanics during a crossover cutting task in female soccer players.
Methods: Eighteen female collegiate soccer players alternated between a fatigue protocol and two consecutive unanticipated crossover trials until fatigue was reached. Lower extremity biomechanics were evaluated during the crossover using a 3D motion capture system and two force plates. Repeated-measures ANOVAs analysed differences between three sequential stages of fatigue (pre, 50, 100%) for each dependent variable (α = 0.05).
Results: Knee flexion angles at initial contact (IC) for pre (-32 ± 9°) and 50% (-29 ± 11°) were significantly higher than at 100% fatigue (-22 ± 9°) (p < 0.001 and p = 0.015, respectively). Knee adduction angles at IC for pre (9 ± 5°) and 50% (8 ± 4°) were significantly higher (p = 0.006 and p = 0.049, respectively) than at 100% fatigue (6 ± 4°).
Conclusions: Fatigue altered sagittal and frontal knee kinematics after 50% fatigue whereupon participants had diminished knee control at initial contact. Interventions should attempt to reduce the negative effects of fatigue on lower extremity biomechanics by promoting appropriate frontal plane alignment and increased knee flexion during fatigue status.

Three-dimensional differences in plantar surface shape captured by methods used for custom accommodative insole design.

Background: The patient-specific shape of custom accommodative insoles for individuals with diabetes provides full foot-to-insole contact, offloading areas with high plantar pressures and reducing ulceration risk. To design the insole surface, plantar surface shape is captured, traditionally with a foam crush box impression or more recently with 3D scans of the foot. Beyond discrete measurements of the foot, the overall plantar surface shapes obtained from these different methods have yet to be compared, however, differences in the shapes captured by these methods may affect the insole's surface geometry design and subsequent performance.

Introduction: In sports, 80% of all ankle injuries are sprains of the external compartment. Functional bandages are usually used preventively, specially in individuals with a history of lateral ankle injuries. To this day, the actual benefits of such taping remain unknown as important modifications are introduced in the ankle biomechanics.

Background: Although transcutaneous spinal cord stimulation (tSCS) has been suggested as a safe and feasible intervention for gait rehabilitation, no studies have determined its effectiveness compared to sham stimulation.
Objective: To determine the effectiveness of tSCS combined with robotic-assisted gait training (RAGT) on lower limb muscle strength and walking function in incomplete spinal cord injury (iSCI) participants.
Methods: A randomized, double-blind, sham-controlled clinical trial was conducted.

Arterial ulcers are a clinical symptom of a complex array of underlying comorbid factors, namely peripheral artery disease (PAD). Chronic limb-threatening ischemia is representative of end-stage PAD. Ulcers of other etiologies can carry an arterial component, mandating recognition of risk factors, a comprehensive history and physical examination, and appropriate diagnostic testing in lower extremity ulcers.
