AI Article Synopsis
- - The study aimed to explore how muscle quality affects patient-reported outcomes and surgery results after lumbar microdiscectomy, analyzing data from patients treated between 2014 and 2021.
- - Findings indicated that while better psoas muscle quality correlated with improved physical health scores at 6 and 12 months, it did not influence surgical outcomes like readmissions or reoperations.
- - The researchers concluded that higher muscle quality could enhance physical recovery post-surgery but didn't impact the likelihood of complications, suggesting the need for further research on this topic.
Article Abstract
Objectives: To investigate the relationship between muscle quality and 1) patient-reported outcomes and 2) surgical outcomes after lumbar microdiscectomy surgery.
Methods: Adult patients (≥18 years) who underwent lumbar microdiscectomy from 2014 to 2021 at a single academic institution were identified. Outcomes were collected during the preoperative, 3-month, 6-month, and 1-year postoperative periods. Those included were the Oswestry Disability Index (ODI), Visual Analog Scale Back and Leg (VAS-Back and VAS-Leg, respectively), and the mental and physical component of the short-form 12 survey (MCS and PCS). Muscle quality was determined by 2 systems: the normalized total psoas area (NTPA) and a paralumbar-based grading system. Surgical outcomes including 90-day surgical readmissions and 1-year reoperations were also collected.
Results: Of the 218 patients identified, 150 had good paralumbar muscle quality and 165 had good psoas muscle quality. Bivariant analysis demonstrated no difference between groups regarding surgical outcomes (P > 0.05). Multivariable analysis demonstrated that better paralumbar muscle quality was not associated with any consistent changes in patient reported outcomes. Higher NTPA was associated with improved PCS at 6 months (est. = 6.703, [95% CI: 0.759-12.646], P = 0.030) and 12 months (est. = 6.625, [95% CI: 0.845-12.405], P = 0.027). There was no association between muscle quality and surgical readmissions or reoperations.
Conclusions: Our analysis demonstrated that higher psoas muscle quality was associated with greater physical improvement postoperatively. Muscle quality did not affect surgical readmissions or reoperations. Additional studies are needed for further assessment of the implications of muscle quality on postoperative outcomes.

Duchenne Muscular Dystrophy (DMD) progressively leads to loss of limb function due to muscle weakness. The incurable nature of the disease shifts the focus to improving quality of life, including assistive supports to improve arm function. Over time, the passive joint impedance (Jimp) of people with DMD increases.

Introduction: Patients with peripheral artery disease (PAD) can experience intermittent claudication, which limits walking capacity and the ability to undertake daily activities. While exercise therapy is an established way to improve walking capacity in people with PAD, it is not feasible in all patients. Neuromuscular electrical stimulation (NMES) provides a way to passively induce repeated muscle contractions and has been widely used as a therapy for chronic conditions that limit functional capacity.

Background Context: Recumbent MRI is the most widely used image modality in people with low back pain (LBP), however, it has been proposed that upright (standing) MRI has advantages over recumbent MRI because of its ability to assess the effects of being weight-bearing. It has been suggested that this produces systematic differences in MRI parameters and differences in the correlation between MRI parameters and pain or disability in patients thus, potentially adding clinically helpful information.
Purpose: This paper aims to review and summarize the available empirical evidence for or against these two hypotheses.

Background: Chronic ankle instability (CAI) has been associated with neuromuscular control dysfunction, particularly of the peroneal musculature.
Research Question: How do neuromuscular characteristics of the peroneal muscles, including corticospinal excitability, strength, proprioception (force sense) and electromyographic measures differ in individuals with CAI compared to healthy control counterparts aged 18-45?
Methods: A systematic review with meta-analysis was conducted by retrieving relevant articles from electronic databases including EBSCOhost (CINAHL Complete, AMED, SPORTDiscus), Ovid (MEDLINE, Embase), Web of Science, Scopus and Cochrane Library as well as Grey literature sources. The eligibility and methodological quality of the included case-control and cross-sectional studies were assessed by two reviewers.

Purpose Of Review: Malnutrition is a significant comorbidity in Chronic Obstructive Pulmonary Disease (COPD), contributing to disease progression and reduced quality of life. This narrative review examines the role of nutritional therapy in the prevention and management of malnutrition in COPD, emphasizing evidence-based approaches and their clinical implications.
Recent Findings: COPD patients face increased metabolic demands, systemic inflammation, and reduced dietary intake, resulting in muscle wasting, sarcopenia, and cachexia.
