TL;DR: Current evidence suggests that patients with diabetic peripheral neuropathy have elevated plantar pressures and occupy a longer duration of time in the stance-phase during gait.

TL;DR: The findings support the need for focused neuromuscular reconditioning across all movement directions in this patient group of femoroacetabular impingement patients.

TL;DR: Whether and how post-stroke individuals adapt their steady-state gait pattern to maintain or increase their margins of stability during walking is examined, and how these strategies differ from strategies employed by able-bodied people is examined.

TL;DR: The results suggest that anterior cruciate ligament loading resulted from a multifaceted interaction of the sagittal plane shear forces (i.e., quadriceps, hamstrings, and tibiofemoral), as well as the frontal and transverse plane knee moments.

TL;DR: It is suggested that improving plantarflexor ability to generate propulsion is critical during rehabilitation regardless of module composition, and rehabilitation should also focus on improving early stance body support and late paretic leg swing.

TL;DR: The second landing of a drop vertical jump task is examined for differences in kinetic and kinematic behaviors at the hip and knee and provides a superior tool to evaluate sagittal plane risk factors than the first landing, which may be better suited to evaluate frontal plane risk Factors.

TL;DR: It is suggested that an outsole design with a 95° apex angle, apex position at 60% of shoe length and 20° rocker angle may achieve an optimal balance for offloading different regions of the forefoot.

TL;DR: The results suggest that gait changes reflect mechanical overload and are most likely the consequence of structural degeneration in knee osteoarthritis.

TL;DR: The magnitudes of the total joint contact forces at the patellofemoral joint, tibiofemoral Joint and hip are greater than those reported in activities of daily living and less dynamic rehabilitation exercises.

TL;DR: The reasonable performance of forefoot pain classification by neural networks suggests that fore foot pain is related more to the distribution of the pressure under the foot than to the absolute values of the Pressure at fixed locations.

TL;DR: Individuals with KOA exhibited increased co-contraction, amplitude and duration of medial knee muscles regardless of disease severity, limb alignment or medial joint laxity, and future research investigating the efficacy of neuromuscular rehabilitation programs should consider the effect of simultaneous up-regulation of medial and lateral knee muscles on disease progression.

TL;DR: Findings suggest that treadmill walk does not involve brain areas susceptible to interference from the introduction of a cognitive task, as they suggest that motor and cognitive performances decline during dual task testing with overground walking.

TL;DR: The findings of this study provide substantial support for arthrogenic inhibition following hip intra-articular fluid instillation during functional tasks and are of clinical importance to both patient and athletic populations.

TL;DR: It is demonstrated that there may be links between lower-extremity muscle weakness, muscle activation patterns, altered gait, and increased cost of walking in older fallers.

TL;DR: Fatiguing exercise negatively affected postural control but not proprioception and Ankle status did not appear to have an effect on fatigue-induced sensorimotor control impairments.

TL;DR: Evaluating the bone rotation of each joint in the medial longitudinal arch and comparing the response in healthy feet with that in flat feet by analyzing the reconstructive three-dimensional CT image data during weightbearing found the flatfoot dorsiflexed more in the first tarsometatarsal joint.

TL;DR: A new soft-layered long spine board is designed that is able to reduce the risk for deformation damage and thus reduces the risk of developing pressure ulcers during prolonged loading.

TL;DR: It was found that it may still be possible to use carefully selected measures of muscle activation in conjunction with external adduction moment measures to account for up to 50% of the variance in medial and lateral compartment loads.

TL;DR: The attenuation of centre-of-pressure trajectory fluctuations when using the hydraulic device indicated bodyweight was transferred onto the prosthetic limb in a smoother, less faltering manner which allowed the centre of mass to translate more quickly over the foot.

TL;DR: Individuals with diabetic neuropathy had increased intrinsic foot muscle deterioration, which was associated with second metatarsophalangeal joint angle and history of ulceration.

TL;DR: The in vitro-measured resulting forces in the glenoid fossa were comparable to the in vivo forces generated in shoulder arthroplasties.

TL;DR: While neuromuscular fatigue of the knee musculature alters the sagittal plane knee moment in healthy, young women during walking, high intensity fatigue is not consistent with known mechanical environments implicated in knee pathologies or injuries.

TL;DR: These results confirm the importance of the suscapularis for the long-term stability of total shoulder arthroplasty and develop an EMG-driven musculoskeletal model of the glenohumeral joint based on an algorithm that minimizes the difference between measured and predicted muscular activities.

TL;DR: It is found that gait compensations were significantly influenced by lower limb alignment, which might help in the understanding of gait compensation behaviours prior to total knee arthroplasty and better manage the strategies of rehabilitation following surgery.

TL;DR: The qualitative survey showed that the prosthesis users experienced fewer problems and increased satisfaction with the Dermo interface system, which caused less pressure within the prosthetic socket compared to the Seal-In X5 interface system during stair negotiation.

TL;DR: Young adults with unilateral transtibial amputation walked across a loose rock surface at three controlled speeds and did not significantly alter their proximal joint kinematics on this irregular surface as a result of the addition of power.

TL;DR: The hypothesis that 6-month postoperative dynamic joint range of motion, time-distance measures and muscle activity in the operated limb in patients undergoing total hip arthroplasty differ from preoperative levels and are more similar to those observed postoperatively in the contralateral limb and in healthy subjects is tested.

TL;DR: Chondrocyte death and Mankin Scores were significantly increased in the loaded joints, thereby linking muscular exercise of physiologic magnitude but excessive intensity to cartilage degeneration and cell death in the rabbit knee.

TL;DR: Patients with hip osteoarthritis demonstrated increased gluteus medius muscle activation levels during stepping tasks and gait when compared to controls, most likely a compensatory response to muscle weakness.

TL;DR: The prioritization of joint load reduction versus additional metabolic and cognitive demands could play a substantial role in the clinical decision making process of selecting a modified gait pattern.
