Summary: This study found that low preoperative radiographic density of erector spinae muscles is associated with poor prognosis after lung transplantation. The prognosis is particularly poor in patients with preoperative steroid use and low radiographic density of the erector spinae muscles.

Summary: This study investigates the effect of an active exoskeleton on back muscle activity when lifting weights. It was found that the use of the active exoskeleton significantly reduces muscle activity and perceived exertion. Therefore, active exoskeletons provide noticeable support when lifting heavy weights, reducing muscle activity and pressure on the lumbar region.

Summary: Individuals with chronic low back pain demonstrate altered muscle activation patterns and decreased peak torque levels during a dynamic fatiguing task compared to asymptomatic controls. Future studies may benefit from utilizing high-density EMG biofeedback to optimize paraspinal muscle activation in individuals with low back pain.

Summary: The aim of this study was to compare the maximal force, force steadiness, and discharge characteristics of motor units in the tibialis anterior muscle during contractions with the dorsiflexors of the dominant and nondominant legs at different ankle angles and target forces. The results showed that the maximal force and force steadiness were similar between the two legs, regardless of the ankle angle or target force. The attributes associated with the dominant leg were not related to the force capacity or control of the dorsiflexor muscles.

Summary: The study found that the passive back-support exosuit effectively reduces erector spinae muscle activity, with no significant impact from asymmetry of posture or lower extremity restrictions. These findings help identify tasks where exoskeleton suits may be effective.

Summary: The study indicates that using a chair with lumbar support, such as the A-chair, provides greater comfort, reduces exertion of the lumbar erector spinae muscles, and decreases discomfort compared to the standard piano stool.

Summary: The erector spinae plane block is one of the proposed 'Plan A' blocks that can be performed at all levels of the spine and provides analgesia to most regions of the body. However, current studies show that it may not be as effective as local infiltration and other Plan A blocks in upper and lower limb surgery. Therefore, there is insufficient evidence to claim it as the ultimate Plan A block.

Summary: This meta-analysis compared the efficacy of erector spinae plane block (ESPB) versus standard medical pain management after major abdominal surgeries. The study found that patients in the ESPB group had significantly reduced opioid requirements and time to first analgesic request, but there were no significant differences in pain scores, nausea, and vomiting between the ESPB and no block groups. No serious complications related to ESPB were reported.

Summary: The retrospective study on asymptomatic adult volunteers found that lumbar lordosis morphology is influenced by pelvic incidence and paraspinal muscle. Proximal lumbar lordosis has a stronger correlation with pelvic incidence compared to distal lumbar lordosis.

Summary: We developed and tested a methodology for identifying individual motor unit (MU) firings from surface high-density EMG recorded Hoffman reflex (H-reflex). Synthetic HD-EMG signals were constructed to simulate different levels of muscle contractions and H-reflexes, while experimental H-reflexes were recorded from 12 men using HD-EMG arrays. The Convolution Kernel Compensation method was used to estimate MU filters, which accurately identified MU firings and latencies in both synthetic and experimental signals.

Summary: This study compares three methods for detecting and estimating the frequency of muscle electrical signals. The new ES method is found to be more accurate and versatile, while the FT and OT methods are more sensitive to amplitude fluctuations.

Summary: The study aimed to evaluate the impact of muscle length on dorsiflexor force steadiness and motor unit discharge characteristics during submaximal contractions. Results showed that muscle length affected force steadiness and the average discharge rate of motor units varied at different ankle angles.

Summary: Fear-avoidance beliefs, especially fear of lifting with a flexed spine, are negatively associated with the spatial distribution of lumbar paraspinal muscle activity in pain-free individuals, indicating potential behavioral alterations to prevent back injury.

Summary: The study investigated the association between erector spinae muscle size and in-hospital mortality in elderly patients with pneumonia, finding that a lower ratio of erector spinae muscle cross-sectional area to body surface area may independently predict in-hospital mortality.

Summary: The combination of ESP and RL blocks showed more extensive and reliable spread of dye compared to ESP block alone in Thiel embalmed cadavers. This indicates that combining the two blocks may be a more effective technique for anesthesia procedures.
