Background: The gastrocnemius and soleus muscle flaps are the most commonly used transfer flaps to treat lower limb severe lesions. The use of the muscle as coverage tissuemay incur in functionality loss and motor control deficits. The aim of this study is to assess whether functional deficits are present during gait, posture and heel rise test (HRT).
Method: From 2008-2013 we treated 9 patients suffering from complex injury of the lower third of the leg (Gustilo III B). A population of 9 patients (group A) was examined after reconstruction with a soleus muscle flap. The results were compared with a control population (group B: 9 patients). Each patient performed at least 3 gait tests at a fast pace, 2 posture tests and 2 HRT on an inclined plane.
Results: Gait parameters for group A: Spatio-temporal parameters such as step length, cadence were reduced compared to the homolateral leg (p < 0.05). The initial double support phase was shorter in relation to the final phase and the first peak in the vertical ground reaction component was reduced compared to the contralateral leg.Posture for the group A: the mediolateral excursion (during open- and closed-eyes test) and the related mean velocity (in the open-eyes test) were significantly lower compared to the control group (p < 0.05).HRT for group A: the number of rises and relative height and angular excursion were reduced in the operated leg in relation to the control group (p < 0.05) and to the contralateral leg.
Conclusion: The patients treated with the soleus muscle used as tissue defect coverage completely recovered the ability to walk but showed some deficits in kinetic parameters during the body weight-loading phase. During gait prolonged muscle activity compared to controls was observed. The absence of soleus (group A) revealed no significant alterations in postural control. However, the HRT remained the most relevant test to measure patients' performance when treated with soleus flap in relation to the control group.

Background: The metabolic score for visceral fat (METS-VF) is a recently identified index for evaluating visceral fat, also referred to as abdominal obesity. The skeletal muscle mass index (SMI) serves as a critical measure for assessing muscle mass and sarcopenia. Both obesity and the reduction of muscle mass can significantly affect human health.

We explore the correlation between muscle viscoelasticity and displacement mechanomyography (DMMG) during passive joint movement. Current methods for assessing muscle viscoelasticity (which is essential for rehabilitation and sports conditioning) are limited in terms of simplicity, objectivity, and portability. We introduce a novel methodology employing DMMG during passive pedaling to evaluate these properties.

Creating durable, motion-compliant neural interfaces is crucial for accessing dynamic tissues under in vivo conditions and linking neural activity with behaviors. Utilizing the self-alignment of nano-fillers in a polymeric matrix under repetitive tension, here, we introduce conductive carbon nanotubes with high aspect ratios into semi-crystalline polyvinyl alcohol hydrogels, and create electrically anisotropic percolation pathways through cyclic stretching. The resulting anisotropic hydrogel fibers (diameter of 187 ± 13 µm) exhibit fatigue resistance (up to 20,000 cycles at 20% strain) with a stretchability of 64.

Many myopathies in horses can be managed by exercise regimes and dietary modifications. This includes modifying the amount of nonstructural carbohydrate, fat, amino acids, vitamin E, and selenium based on the horse's specific myopathy, metabolic status, exercise program, and optimal body weight. Because dietary recommendations differ substantially between myopathies, it is imperative to establish a specific diagnosis.

The effects of flywheel (FW) training on jump performance, muscle function, and muscle mass in athletes have not been fully clarified. The purpose of the present study was to evaluate the effects of an 8-week FW training program on jump performance, stretch-shortening cycle (SSC) function, muscle strength, peak power and muscle thickness in collegiate basketball players. Twenty male college basketball players (mean age: 19.
