Histopathological Changes of Extensor Digitorum Longus Muscle Following Sciatic Nerve Transection: The Role of Mast Cells and Mesenchymal Stem Cells

SUMMARY Objectives. Damage caused by the sciatic nerve transection leads to histopathological changes of related skeletal muscles such as atrophy, necrosis, etc. In this study, these changes and ameliorative effects of using mast cells and mesenchymal stem cells along with collagen gel scaffold at the nerve’s transection site were evaluated. Methods. For this purpose, 90 … Continued

Change in Polygon Shapes of Atrophic and Small Angular Fibers in Disuse Muscle Atrophy

SUMMARY Background. Muscle fiber (MF) cross-sectional area (CSA) and muscle strength are reduced in disuse muscle atrophy (DMA). However, whether approximate shapes of MF cross-section (AS-MFCS) are altered in DMA remains unknown. This study aimed to determine the AS-MFCS of atrophic MFs. Methods. Eleven-week-old male Wistar rats were divided into control (CON) and sciatic nerve … Continued

Development and Validation of the Musculoskeletal Health Questionnaire (MSK-HQ) on an Italian Population of Padel and Tennis Players: A Cross-Sectional Study

SUMMARY Introduction. In racquet sports, players are particularly prone to a variety of musculoskeletal issues due to the repetitive and high-intensity nature of their movements, which can lead to overuse injuries, acute trauma, and chronic conditions. The Musculoskeletal Health Questionnaire (MSK-HQ) is a comprehensive tool designed to assess a wide range of musculoskeletal health parameters, … Continued

Acute Structural Repercussions of Vertical Ladder Training on the Muscle Belly of Wistar Rats after Joint Immobilization

SUMMARY Background. Resistance training promotes positive musculoskeletal adaptations that reverse changes in long-term muscle atrophy, elucidating the progression and coordination of acute muscle remodeling caused by resistance training without additional load. Objective. The aim was to describe the morphological changes and the acute period of remodeling in the gastrocnemius muscle, after muscular atrophy caused by … Continued

Effect of the Low Pressure Fitness (LPF®) Technique on Diastasis Recti Abdominis in Postpartum Women: Protocol for A Blinded Randomized Clinical Trial

SUMMARY Introduction. In the postpartum period, the female body undergoes hormonal, anatomical, and physiological changes that can negatively impact musculoskeletal health and lead to conditions such as Diastasis Recti Abdominis. Low Pressure Fitness (LPF®) has been used in clinical practice; however, there is still no consensus on its effects on the abdominal wall and whether … Continued

Relationship Between the Use of Androgenic- Anabolic Steroids and the Incidence of Myoarticular Injuries

SUMMARY Purpose. Androgenic-anabolic steroids (AAS) are a group of hormones that include testosterone and its synthetic derivatives. AAS are widely used for performance enhancement or aesthetic purposes. The use of these substances is well known for causing several negative effects on the cardiovascular system and the hypothalamic-pituitary-gonadal axis, among other systems. However, the effects on … Continued

Evaluating Shoulder Rotation Strength Asymmetry in Elite Wheelchair Basketball and Sitting Volleyball Players

SUMMARY Background. Although an imbalanced strength profile is considered a risk factor for injury, research on asymmetry in para-athletes is limited. Objective. This study investigated the potential unilateral and bilateral asymmetries of the glenohumeral muscles in elite male players of sitting volleyball (SV) and wheelchair basketball (WB). Methods. Twenty-two elite SV and WB players (each … Continued

Dislocation/Fracture of Proximal 5th Metatarsal: New Protocol with Self-Assessment Scale and Specific Plantar Orthosis

SUMMARY Background. Metatarsal dislocations/fractures represent a significant proportion of foot injuries. There has been conflicting literature on the management of proximal 5th metatarsal injury, due to inconsistency concerning the classification of these conditions. Various patterns of metatarsal injuries exist and the resultant impact on function and quality of life is not negligible. A complete clinical … Continued

Enhancing Foot Posture and Balance in Flexible Flatfoot: Short Foot Exercise, Balance Training, and Plyometrics Approach

SUMMARY Objective. The purpose of this study was to evaluate the effects of short foot exercise along with dynamic balance training and plyometric exercise training by using the navicular drop test on improving the foot posture and Y balance test for dynamic balance. Methods. In this comparative study, 66 participants aged 18-30, using convenient sampling … Continued
