Background: The purpose of this study verify the immediate effect of whole body vibration (WBV) on quadriceps muscle strength, functional mobility and balance in elderly patients with Osteopenia and/or Osteoporosis.
Methods: This was a randomized pragmatic clinical trial with 34 elderly (32 women) randomly assigned to two groups: the experimental group (EG; = 17) who underwent low-frequency (16 Hz) WBV and the control group (CG; n = 17) who performed the walk. Outcome measures were: quadriceps muscle strength measured by a maximal repetition test (1RM); functional mobility assessed by the Timed Up and Go (TUG) test and balance assessed by the Berg Balance Scale (BBS).
Results: In within-group interaction, a significant increase was observed in quadriceps muscle strength (EG: = 0.047) and balance (EG: p = 0,012; CG: p = 0,007). In between-groups interaction, a significant difference was not observed. There was an increase in the muscular strength of the EG and in the balance in both groups.
Conclusion: An WBV training session was able to alter the muscular strength of the LQ and the balance of the elderly with Osteopenia and/or Osteoporosis. It is suggested, however, that future studies involving larger sample number and/or populations should be developed to analyze the short-term effects of WBV.

Alterations in whole muscle quality and physiological cross-sectional area measured with quantitative MRI following ACL injury.

Background: Emerging evidence suggests that there are morphological and physiological changes to the vastus lateralis after an anterior cruciate ligament (ACL) tear. However, it is unclear whether these alterations are limited to just the vastus lateralis or are more representative of widespread changes across the thigh musculature and/or if these changes precede reconstruction. The purpose of this study was to determine T1ρ relaxation time, a measure of extracellular matrix organization in muscle, and physiological cross-sectional area (PCSA) for muscles of the quadriceps and hamstrings of the ACL-deficient and contralateral limbs soon after ACL injury.

Obesity is one of the most common chronic diseases seen in children and adolescents. This study aims to examine the impact of obesity on body composition, assessed by sonographic and anthropometric measurements, and health-related quality of life (HRQoL) in adolescents.Anthropometric measurements, sonographic measurements of subcutaneous fat, quadriceps muscle, Achilles tendon thickness, and HRQoL were performed in children between 12-18 years of age.

Introduction: Soft-tissue sarcomas arising in the thigh may require total or subtotal compartmentectomy, with subsequent need for functional reconstruction with free functional muscle transfer (FFMT). We present our series, describing a new approach with chimeric propeller antero-lateral thigh-vastus lateralis (ALT-VL) free flap, which allows for independent muscle inset and soft tissue defect resurfacing.
Patient And Methods: A retrospective review of a prospectively maintained database was performed, analyzing all patients referred to Fondazione Policlinico Universitario Campus Bio-Medico, Rome, Italy, between 2018 and 2023 for soft-tissue sarcomas of the thigh requiring wide excision and reconstruction with functional ALT-VL.
Clinical SANTI classification of arthrogenic muscle inhibition has an excellent inter-rater and intra-rater reliability in preoperative and post-operative anterior cruciate ligament rupture.

Purpose: Arthrogenic muscle inhibition (AMI) is a reflexive shutdown of the quadriceps muscles following a knee injury or surgery that presents with or without hamstring contracture. This complication can be classified according to the SANTI classification, but the reproducibility of this clinical classification has not yet been demonstrated.
Methods: This single-centre longitudinal observational study included 140 patients who were within 6 weeks of an ACL rupture.
Changes in Muscle Quality Following Short-Term Resistance Training in Older Adults: A Comparison of Echo Intensity and Texture Analysis.

Background: Skeletal muscle echo intensity (EI) is associated with functional outcomes in older adults, but resistance training interventions have shown mixed results. Texture analysis has been proposed as a novel approach for assessing muscle quality, as it captures spatial relationships between pixels. It is unclear whether texture analysis is able to track changes following resistance training.
