Altered anconeus muscle activation characteristics during isometric gripping in individuals with lateral elbow tendinopathy compared to age- and sex-matched control.

Article Synopsis
- This study explored how the anconeus muscle activates during gripping in individuals with Lateral Epicondyle Tendinopathy (LET), who often experience pain and weakened grip.
- Participants with LET showed increased activation of the anconeus compared to forearm muscles during gripping, indicating a possible compensatory mechanism.
- Understanding these changes in muscle activation can help explain the gripping difficulties associated with LET and may lead to better treatment strategies.
Enhancing Mobility: Surgical Deformity Correction and Rehabilitation in Emery-Dreifuss Muscular Dystrophy Type 2.

Emery-Dreifuss Muscular Dystrophy (EDMD) is a rare genetic disorder characterized by muscle weakness, joint contractures, and cardiac dysfunction. Within this spectrum, EDMD Type 2, attributed to a heterozygous missense variant in exon 9 of the LMNA gene, presents a distinctive clinical profile. This case report details the presentation and management of a teenage girl displaying neck, trunk, upper and lower limb weakness, Achilles tendon contracture, and lordosis.

Objectives: The cerebral cortex contains neurons that play a pivotal role in controlling rhythmic masticatory jaw movements. However, the population characteristics of individual cortical neuronal activity during mastication and the impact of tooth loss on these characteristics remain unclear. Thus, in this study, we aimed to determine the activity patterns of mastication-related motor cortical neurons elicited during mastication and examine the effects of tooth extraction on neuronal activity using two-photon Ca imaging in head-restrained awake mice.

The role of the human ankle joint in activities of daily living, including walking, maintaining balance, and participating in sports, is of paramount importance. Ankle joint dorsiflexion and plantarflexion functionalities mainly account for ground clearance and propulsion power generation during locomotion tasks, where those functionalities are driven by the contraction of ankle joint skeleton muscles. Studies of corresponding muscle contractility during ankle dynamic functions will facilitate us to better understand the joint torque/power generation mechanism, better diagnose potential muscular disorders on the ankle joint, or better develop wearable assistive/rehabilitative robotic devices that assist in community ambulation.

In ulnar neuropathy at the elbow (UNE), the degree of neuropathic changes, the sensitivity of needle electromyography (EMG) in individual ulnar muscles, and the utility of individual EMG parameters are controversial. I compared qualitative needle EMG findings in two ulnar-innervated hands muscles and two ulnar-innervated forearm muscles in a group of previously reported UNE patients. Altogether, 170 UNE patients (175 arms) were studied.
