Article Synopsis
  • Advanced chronic kidney disease affects muscle health, making it important to find effective ways to assess muscle quality before kidney transplants.
  • Musculoskeletal ultrasound, particularly measuring rectus femoris (RF) echogenicity, shows promise in identifying muscle weakness and quality issues in patients waiting for kidney transplants.
  • In a study of 112 patients, a RF echogenicity cut-off of 70 demonstrated good sensitivity but moderate specificity for detecting quadriceps weakness, indicating an increased risk in patients with greater echogenicity.

Resistance exercise and protein supplementation are recognized as effective treatment strategies for age-related sarcopenia; however, there are limited data on their feasibility, tolerability, and safety. The primary outcome of this study was feasibility, evaluated through the 15-item TELOS (Technological, Economics, Legal, Operational, and Scheduling) feasibility components and by recruitment, retention, and consent rates. Tolerability was measured by examining permanent treatment discontinuation, treatment interruption, exercise dose modification, early termination, rescheduling of missed sessions, losses to follow-up, attendance, and nutritional compliance.

Phase angle (PhA), a marker of nutritional status obtained by bioelectrical impedance analysis (BIA), is associated with the integrity of cell membranes. Damage to muscle fiber membranes can impact muscle strength, which is related to adverse outcomes in adults with advanced chronic kidney disease (CKD). The main objective of this study was to determine the usefulness of the PhA in identifying muscle weakness in candidates for kidney transplants (KTs).

Objectives: This study aimed to evaluate the efficacy of adding β-hydroxy-β- methylbutyrate (HMB) supplementation to a 12-week exercise-based rehabilitation program in older adults with sarcopenia after discharge from a post-acute geriatric rehabilitation unit.

Study Design: A randomized, double-blind, placebo-controlled trial with two parallel groups. The intervention group received 3 g/day of Ca-HMB and participated in a 12- week resistance training program (3 sessions/week).

Introduction And Objective: Hippotherapy (HPOT) and hippotherapy simulators (SHPOT) are used in children with cerebral palsy to achieve their maximum functionality and independence. The aim is to find out if HPOT and SHPOT produce the same effects on balance, gross motor function, and postural control in children under 18 years old with cerebral palsy.

Materials And Methods: The keywords used were: hippotherapy, equine-assisted therapy and cerebral palsy.
