Relationship to drill bit diameter and residual fracture resistance of the distal tibia
All the tested drill hole sizes in this study significantly reduced the torque-to-failure from intact by a range of 28.4% to 38.4%, in agreement with previous similar studies. The 5  mm drill hole represented a 22.7% diameter defect, the 4 mm drill hole a 18.2% diameter defect, and the 3 mm drill hole a 13.6% diameter defect. Clinicians should be cognizant of this diminution of long bone strength after a residual bone defect in their creation and management of patient reh abilitation programs.

Three decades of gait index development: A comparative review of clinical and research gait indices
This work is one of the first reviews to summarize observational and instrumented gait indices, exploring their applicability in research and clinical contexts. The aim of this review is to assist members of these communities with the selection of the proper index for the group in analysis. (Source: Clinical Biomechanics)

Tibio-femoral kinematics of natural versus replaced knees – A comparison using dynamic videofluoroscopy
Each total knee replacement design exhibited characteristic motion patterns, with the GMK Sphere most closely replicating the medial centre of rotation found for natural knees. Despite substantial similarities between the subject groups, none of the implant geometries was able to replicate all aspects of natural tibio-femoral kinematics, indicating that different implant geometries might best address individual functional needs.

Evaluation of overall gait quality in Perthes disease. Are global gait indices of value for a local musculoskeletal disorder?
The evaluated gait indices are sensitive to identify a pathologic gait pattern in Perthes disease, so they can be used as a functional outcome parameter evaluating treatment concepts. Nevertheless, these are not applicable to identify the pathologic side indicating that a local hip problem leads to global gait deviations. (Source: Clinical Biomechanics)

Load-deformation characteristics of cadaver patellae: Relationship to intraosseous pressure
Load-deformation of cadaver patellae results in deformation and an increase in intraosseous pressure. These findings may help explain previous studies of patellofemoral pain where elevated patellar intraosseous pressures have been found in vivo. (Source: Clinical Biomechanics)

Structural and passive mechanical properties of the medial gastrocnemius muscle in ambulatory individuals with chronic stroke
Although muscle mechanical properties increased exponentially over the slack ankle, measures between paretic and non-paretic sides were similar in ambulating participants with chronic stroke. Side-to-side differences in structural and morphological measures suggest the impact of stroke was relatively more pronounced for these muscle parameters than for passive mechanical properties.

Vastus medialis intramuscular fat is associated with reduced quadriceps strength, but not knee osteoarthritis severity
Greater vastus medialis intramuscular fat was associated with lower quadriceps muscle strength in patients with knee OA. It is unclear whether this is due to the accumulation of vastus medialis intramuscular fat or other potential factors, such as diet and physical inactivity. (Source: Clinical Biomechanics)

Motion sickness decreases low back function and changes gene expression in military aircrew
Motion sickness may alter standing balance, decrease low back function, and lead to changes in the expression of genes with roles in osteogenesis, myogenesis, development of brain lymphatics, inflammation, neuropathic pain, and more. These results may provide preliminary evidence for a link between motion sickness and low back disorders. (Source: Clinical Biomechanics)

Implications of lower extremity muscle power and force for walking and fatigability in multiple sclerosis – An exploratory pilot-study
Muscle power and force are impaired in persons with MS and appear to be critical for physical function in MS. This exploratory pilot study further suggests that muscle power/force from chair rise could contributes to walking-fatigability which therefore offer future treatment targets.

Recovery of the medial gastrocnemius muscle after calcaneus fracture differs between contractile and elastic components.
Patients with calcaneal fracture showed an incomplete restoration of the medial gastrocnemius dynamic morphological behavior. While muscle fascicle contraction almost recovered, the serial elastic component still showed restrictions regarding its shortening behavior. Limited foot mobility and plantarflexor strength as well as lowered responsiveness of elastic tissues to mechanical loading are regarded as key mechanisms. (Source: Clinical Biomechanics)

Effects of limited previously acquired information about falling height on lower limb biomechanics when individuals are landing with limited visual input
The results of this study indicate that the risk of anterior cruciate ligament injury during landing increases when individuals have limited visual input and prior knowledge of the height of the fall. This finding suggests that an accurate perception of the surrounding environment may help prevent anterior cruciate ligament injuries. (Source: Clinical Biomechanics)
