Journal ArticleDOI
TL;DR: In a native medial patellofemoral ligament, 20° of increased internal femoral torsion can be regarded as a significant risk factor for patellar instability.

71 citations


Journal ArticleDOI
TL;DR: The results of this study suggest that LBP is associated with muscle stiffness of the lumbar multifidus muscle in young and middle‐aged medical workers.

61 citations


Journal ArticleDOI
TL;DR: Despite vastly different geometries, consistent flow patterns are identified including relatively high velocity in the nasal valve region, followed by flow continuing predominantly in the inferior half of the airway.

50 citations


Journal ArticleDOI
TL;DR: Real‐time biofeedback directly on the knee adduction moment is a promising option for encouraging gait modifications to reduce knee loading, however only when combined with specific instructions on how to modify the gait.

47 citations


Journal ArticleDOI
TL;DR: Harmony of gait appears to be a benchmark of physiological gait leading to physiological energy recovery and gait reliability, and Neurorehabilitation of patients with ataxia might benefit from the restoration of harmony of their locomotor patterns.

45 citations


Journal ArticleDOI
TL;DR: Clinical diagnosis should make allowances for observed differences in pelvic floor deformations between a Valsalva maneuver and a jump‐landing process to ensure accuracy, and reduced stiffness of levator ani muscle plays a small role in causing urethral hypermobility.

41 citations


Journal ArticleDOI
TL;DR: Preliminary evidence that people with low back pain adopt consistent movement patterns during the performance of functional activities is provided, indicating that the lumbar spine consistently moves more readily into its available range in people withLow back pain and high levels of functional limitation.

39 citations


Journal ArticleDOI
TL;DR: There was strong evidence that stance phase duration is unchanged and reduced rearfoot loading early in stance resulted in variable compensations later, which will help determine clinical relevance of gait analysis/treatment.

39 citations


Journal ArticleDOI
TL;DR: Realistic movement of the airway is incorporated into CFD simulations of airflow in the upper airway for the first time and will allow novel analysis of dynamic conditions, such as sleep apnoea.

39 citations


Journal ArticleDOI
TL;DR: The use of predictive models could enable clinicians to identify individuals at risk of knee osteoarthritis and be a cost‐effective method for osteoartritis screening.

38 citations


Journal ArticleDOI
TL;DR: Positive correlations between the Ashworth score and lower limb Muscle Coactivation suggest that abnormal lower limb muscle coactivation in patients with hereditary spastic paraparesis reflects a primary deficit linked to lower limb spasticity.

Journal ArticleDOI
TL;DR: The sway volume metric not only differentiated a group with concussion from a healthy control group, but successfully identified when task errors had occurred, which may be of value in the development of a pitch‐side assessment system for concussion.

Journal ArticleDOI
TL;DR: A novel mechanical impact simulator will allow researchers to assess clinically relevant patterns of rupture and the data generated will inform clinician decisions, and is the first ligament injury simulator to consistently generate failure in clinical location.

Journal ArticleDOI
TL;DR: Through a minimally invasive procedure, the removal of spinal fixators after complete fusion could reduce secondary damage to the paraspinal structures while removing the fixators, which is of utmost concern to surgeons.

Journal ArticleDOI
TL;DR: For cancer survivors undergoing rehabilitation focused on existing balance deficits, a small subset of the center of pressure measures presented here can be used to track progress throughout the intervention and potentially mitigate fall risk.

Journal ArticleDOI
TL;DR: Running with a shorter step length is a feasible clinical intervention to reduce knee joint contact forces during running among people with a history of anterior cruciate ligament reconstruction.

Journal ArticleDOI
TL;DR: Changes in sagittal‐plane kinematics and kinetics were similar to those previously observed in straight‐line walking, which suggests that actively adjusting stiffness to turn direction may be beneficial.

Journal ArticleDOI
TL;DR: The reduced peak pressures and wider load distributions over the sensor during both passive abduction‐adduction and flexion‐extension motions suggest that the use of the spacer will lead to reduced wear of the repair in patients, and potentially prevent rotator cuff re‐tear after surgical repair.

Journal ArticleDOI
TL;DR: A small atlas of the changes in gait characteristics associated with different disability levels in the Multiple Sclerosis population is provided to effectively track the progression of MS and the effect of different therapies.

Journal ArticleDOI
TL;DR: Reduced lumbar range of flexion and slower task pace, observed in patients with acute low back pain, may be the result of a neuromuscular adaptation to reduce the forces and deformation in the lower back tissues and avoid pain aggravation.

Journal ArticleDOI
TL;DR: Assessment of motor control exercise effects on spinal stability using a biomechanical model yielded no significant difference in disability, pain and stability index between two groups, and significant increase of stability in the motor control group at right lateral pulling may be attributed to more activity of abdominal muscles.

Journal ArticleDOI
TL;DR: Refixation of the lesser trochanter may increase the primary stability of pertrochanteric fracture osteosynthesis as all groups showed a higher primary stability, and refixation should be considered in unstable, osteoporotic fractures.

Journal ArticleDOI
TL;DR: This study indicates that while those with and without femoroacetabular impingement exhibit many biomechanical similarities when ascending stairs, differences in trunk forward flexion and joint kinetics indicate some important differences.

Journal ArticleDOI
TL;DR: In this paper, a finite element method coupled with a bone remodelling model is used to evaluate how different three-dimensional prosthesis models influence distribution of the density of bone tissue.

Journal ArticleDOI
TL;DR: The results indicate that there are non‐uniform changes in passive stiffness of stroke‐impaired muscle, therefore, muscles need to be evaluated individually to assess alterations.

Journal ArticleDOI
TL;DR: Running with a 10% reduction in stride length did not appear to be a beneficial technique for reducing the risk of metatarsal stress fracture, however the increased number of loading cycles for a given distance was not detrimental either.

Journal ArticleDOI
TL;DR: There are decreases in fascicle length, muscle thickness and mechanical properties in the medial gastrocnemius muscles of the participants within the first six months after an Achilles repair, which indicated the need for early mobilization of the calf muscles after the repair.

Journal ArticleDOI
TL;DR: Hip and trunk strengthening increased maximum work of hip lateral rotators muscles and changed hip resting position toward lateral rotation, and reduced lower limb adduction during step‐down task.

Journal ArticleDOI
TL;DR: This easy‐to‐apply functional test is better suited compared to isokinetic testing procedures to assess weakness of evertors in patients suffering from chronic ankle instability and may also be used to objectively monitor improvements during rehabilitation or progression in prevention protocols.

Journal ArticleDOI
TL;DR: This study shows that even though articular cartilage can appear visibly normal under macroscopic observation, the micro‐scale structural changes associated with very early stage osteoarthritis can have a significant effect on its vulnerability to impact damage.
