Why 43.5% of Brazilian women with systemic sclerosis have an abnormal 6-min walk distance? The implication of parity
We read with great interest the recent article titled “Reference value for the 6-min walking distance in women with systemic sclerosis considering the impact of muscle strength” (de Oliveira Saraiva et al., 2023). We found very inspiring the establishment of a reference equation for the 6-min walking distance (6MWD) in women with interstitial lung disease related to a systemic sclerosis (ILDss) as it accounts for the effects of muscle and lung function (de Oliveira Saraiva et al., 2023). The 6-min walk test (6MWT) serves as a standardized, practical, and useful assessment of submaximal exercise capacity, particularly i...

Joint instability in patients with borderline developmental dysplasia of the hip
Borderline developmental dysplasia of the hip is a heterogeneous condition characterized by varying hip instability levels. Our findings suggest that uniform evaluation based on the lateral center-edge angle is inappropriate and that joint instability must be evaluated in each patient with borderline developmental dysplasia of the hip.

We thank Dr. Khansa Derbel and Dr. Helmi Ben Saad for their comments (Derbel and Ben Saad, 2023) on our article “Reference value for the 6-min walking distance in women with systemic sclerosis considering the impact of muscle strength” (de Oliveira Saraiva et al., 2023). We would like to take this opportunity to address the concerns that are outlined in their letter. (Source: Clinical Biomechanics)

Strength and passive stiffness of the quadriceps are associated with patellar alignment in older adults with knee pain
Quadriceps strength and relative stiffness of lateral to medial heads are associated with patellar alignment in older adults with knee pain. It suggests that quadriceps weakness and relatively stiffer lateral quadriceps may be risk factors related to patellar malalignments in the elderly. (Source: Clinical Biomechanics)

Biomechanical effects of osteoporosis severity on the occurrence of proximal junctional kyphosis following long-segment posterior thoracolumbar fusion
Osteoporosis had an adverse effect on proximal junctional kyphosis. The stress levels in cortical bone, intervertebral discs and screws were increased with bone mass loss, which can easily lead to intervertebral disc degeneration, bone destruction as well as screw pullout. These factors have significantly affected or accelerated the occurrence of proximal junctional kyphosis. (Source: Clinical Biomechanics)

Engineering the perfect mattress: The influence of substrate mechanics on deep tissue stresses in supine
The non-linearity of the foam substrate had a pressure distributing effect, relieving the peak compressive stresses at the sacrum, indicating that it may be possible to design arrays of foam substrates that can provide most efficient pressure relief. (Source: Clinical Biomechanics)

Preservation of the posterolateral cortex may not affect the biomechanical stability of lateral intra-articular varus osteotomy of the proximal tibia
The findings indicate that there was no significant difference in stability between the 2 groups under the tested loading conditions. Furthermore, it appears that preserving the posterolateral cortex may have no impact on biomechanical stability. (Source: Clinical Biomechanics)

An analytical model of lateral condylar plate working length
The strain predicted by the analytical model was consistent with the strain observed in both the finite element and biomechanical models. As demonstrated in existing literature, increasing the working length increases strain at the fracture site. Additional work is required to refine and establish validity and reliability of the analytical model. (Source: Clinical Biomechanics)

External weight mass and carrying position influence peak patellar tendon force and patellofemoral joint contact force independently during forward lunge
An external weight's mass and position both influence the peak patellar tendon force and patellofemoral joint contact force during a forward lunge. The rate of increase in peak forces with increasing mass was similar for all weight-carrying positions. (Source: Clinical Biomechanics)
