Impact of Sex and Stretch-Shortening Cycle Induced-Fatigue on Limb Stiffness and Limb Stiffness Asymmetry During the Stop-Jump
… with the onset of fatigue. Asymmetry values for peak knee flexion angle, absolute value of knee flexion angle at initial contact (IC), and loading rate were also assessed before and after fatigue. Significant interactions for asymmetry values of peak knee flexion angle and absolute value of knee …

Effects of prophylactic lace-up ankle braces on kinetics and kinematics of the lower extremity during a state of fatigue.
… range of motion has the potential to alter knee kinematics and is linked to chronic knee pathologies. Thirteen college-aged (6 males) and (7 females) experienced in landing/cutting sports completed a random crossover design study consisting of a 90° cutting task and a 15m beep test fatigue …

Bodyweight Squat Movement Changes after a High-Intensity Short-Rest Workout
… squats before and after a HISR workout. Peak angle, total displacement and rate were assessed for knee flexion, trunk flexion, hip flexion, hip rotation and hip adduction. Subjects were split in to two groups: high lactate (n=7) and low lactate (n=7). Separate 2x2 mixed model ANOVAs were …

Integrated Prosthetic Leg Design Frameworks for People with an Above-Knee Amputation
… low-cost, high biomechanical performance above-knee prosthetic leg components (prosthetic foot and knee) that will result in a walking motion likely to be perceived as able-bodied after minimal acclimation time. Above-knee amputees have two common gait deviations from able-bodied and below-knee …

Evaluation of movement variability and knee biomechanics during functional sporting tasks in healthy individuals and individuals following Anterior Cruciate Ligament Injury (ACL) and ACL reconstruction
… which can occur during some sporting activities. Knee biomechanics and movement variability (MV) comprise two very important aspects relating to injury risk, where it has been suggested that the latter may play a role in ACL injury. AimThe aims of this thesis were: to investigate MV and knee …

Exploring the role of damping in a passive prosthetic knee through modeling, design, and testing
With about 440,000 people with an above-knee amputation in India alone, there is a great need for high performance prosthetic knee. Due to socio-economic stigma associated with amputation, one of the main requirements for a lower limb prosthesis is achieving able-bodied kinematics. However, the …

Effects of Increased Shoe Collar Height and Limb Dominance on Landing Knee Biomechanics in Collegiate Volleyball Players
… to restrict ankle motion. Reduced ankle dorsiflexion has been associated with increased frontal plane knee motion. Volleyball players wear mid-cut shoes (MC) that have an increased collar height rising slightly superior to the talocrural joint and malleoli. The purpose of this study was to …

Clinical investigation of the functional outcome of fixed bearing versus mobile bearing knees
Total Knee Arthroplasty is a high-volume and high-cost procedure, with persisting limitations to patient satisfaction. Prosthesis designs aim to restore function whilst providing stability, without joint constraint. This double-blinded randomised controlled trial is the first of its kind where the …

Factors associated with stiff knee gait in cerebral palsy
Stiff knee gait (SKG) is one of a few classified walking patterns which people with cerebral palsy (pwCP) can present with. The characteristic for SKG is delayed and/or reduced peak knee flexion during swing phase, which can reduce walking ability and result in functional restrictions. Through the …

The Influence of Heel Height on Sagittal Plane Knee Kinematics during Landing Tasks in Recreationally Active Collegiate Females
… to athletic shoe wear would alter sagittal plane knee kinematics when landing from jumping maneuvers. The hypothesis was that increased heel height would increase knee flexion at initial contact (KAIC), increase the peak knee flexion angle (KAPeak), and slow the rate of knee excursion (RKE). Fifty …

A randomised control trial for the restoration of functional ability in patients post total knee arthroplasty: Eccentric versus concentric cycling ergometry
Introduction: While the total knee arthroplasty procedure improves joint-specific outcomes, including pain and range of movement, functional deficits post-surgery has been noted. Movement abnormalities and quadriceps weakness of the operated limb, as well as a decrease in strength on the …

Trail runners: Neuromuscular and biomechanical insights
… ankle varus and less ankle external rotation at peak knee flexion in comparison to road runners. These findings suggest that trail runners’ performance in the SLS test may represent a kinematic adaptation to habitual terrain targeted at minimising ankle joint movement during weight-bearing. …

Functional tasks before and after an anterior cruciate ligament (ACL) reconstruction : are there mechanical differences?
