[Purpose] This study examined the effects of neuromuscular joint facilitation on bridging exercises by assessing the cross-sectional area of the multifidus muscle and thickness of the musculus transversus abdominis. [Subjects] Twelve healthy men. [Methods] Four exercises were evaluated: (a) supine resting, (b) bridging resistance exercise involving posterior pelvic tilting, (c) bridging resistance exercise involving anterior pelvic tilting, and (d) bridging resistance exercise involving neuromuscular joint facilitation. The cross-sectional area of the multifidus muscle and thickness of the musculus transversus abdominis were measured during each exercise. [Results] The cross-sectional area of the multifidus muscle and thickness of the musculus transversus abdominis were significantly greater in the neuromuscular joint facilitation group than the others. [Conclusion] Neuromuscular joint facilitation intervention improves the function of deep muscles such as the multifidus muscle and musculus transversus abdominis. Therefore, it can be recommended for application in clinical treatments such as that for back pain.

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.

Throughout childhood growth and development, both the nervous and the musculoskeletal systems undergo rapid change. The goal of this study was to examine the impact of growth-related changes in skeletal size and muscle strength on the neural control of finger force generation. By modifying an existing OpenSim hand model in accordance with pediatric anthropometric data, we created 10 distinct models representing males and females at each year of development from 6 to 10 years old.

: A degenerative joint disease that primarily affects elderly individuals, osteoarthritis (OA) causes pain, decreased mobility, and a lower quality of life. Procaine is regarded as a "veteran" medicine due to its extensive clinical use, although it remains a molecule of interest, as researchers are uncovering new biological and pharmacological effects through innovative experimental methods. This study evaluates the efficacy of the "procaine complex", developed in our country, in alleviating pain and improving functionality in elderly individuals with osteoarthritis of the knee and hip.

Background: Patellofemoral pain syndrome (PFPS) is one of the most common conditions affecting the knee joint, yet its pathomechanics remain unclear. The aim of this study was to investigate changes in muscle activation and gait patterns and to analyze the relationship between muscle activation and kinetic gait patterns in patients with PFPS.
Methods: This study included 31 patients with PFPS and 28 healthy volunteers without any symptoms.

Continuous relative phase (CRP) quantifies coordination for cyclic motions as the difference in the phase portrait locations between its constituent coordinates and has been widely used in populations with neuromuscular impairments. Continuous analyses, like statistical parameter mapping (SPM), provide greater resolution than traditional techniques that first compress CRP across a section of the cycle to a single point, like mean average relative phase (MARP). However, both analyses neglect the effect of intermediate event timing (e.
