BACKGROUND AND OBJECTIVE: Solving the redundant optimization problem for human muscles depends on the cost function. Choosing the appropriate cost function helps to address a specific problem. Muscle synergies are currently limited to those obtained by electromyography. Furthermore, debate continues regarding whether muscle synergy is derived or real. This study proposes new cost functions based on the muscle synergy hypothesis for solving the optimal muscle force output problem through musculoskeletal modeling...

BACKGROUND: Musculoskeletal conditions are a leading contributor to disability worldwide. The treatment of these conditions accounts for 7% of health care costs in Germany and is often provided by physiotherapists. Yet, an overview of the cost-effectiveness of treatments for musculoskeletal conditions offered by physiotherapists is missing. This review aims to provide an overview of full economic evaluations of interventions for musculoskeletal conditions offered by physiotherapists. METHODS: We systematically searched for publications in Medline, EconLit, and NHS-EED...

Fibromyalgia syndrome (FMS) is a common chronic pain disorder and often occurs as a concomitant disease in rheumatological diseases. Managing FMS takes a complex approach and often involves various non-pharmacological therapies. Fasting interventions have not been in the focus of research until recently, but preliminary data have shown effects on short- and medium-term pain as well as on physical and psychosomatic outcomes in different chronic pain disorders. This single-arm observational study investigated the effects of prolonged fasting (3-12 days, <600 kcal/d) embedded in a multimodal treatment setting on inpatients with FMS...

Background: Achondroplasia is a rare genetic disease, yet the most common form of dwarfism, characterized by limb shortening and disproportionate short stature along with musculoskeletal changes, such as postural deviations. Although postural changes in the spine in children with achondroplasia have been well investigated, little is known about the association of achondroplasia with spinal movements/mobility. Methods: This preliminary study aims to explore the association of achondroplasia with spinal mobility in children with achondroplasia compared to age- and sex-matched healthy individuals...

Musculoskeletal conditions of the upper and lower extremities are commonly treated with corticosteroid injections. Ketorolac, a parenteral nonsteroidal anti-inflammatory drug, represents an alternative injectant for common shoulder, hip, and knee conditions. A review of the current literature was conducted on the efficacy of ketorolac injection in musculoskeletal diseases. Several studies support the use and efficacy of ketorolac injection in subacromial bursitis, adhesive capsulitis, and hip and knee osteoarthritis...

Children born with structural or functional defects were reported as congenital anomalies. The rate of these deficits has increasingly been reported globally with upregulated trends for unknown specific reasons. Congenital anomalies are reported as a clinical challenge for clinical settings due to handling, transportation, daycare, and staff requirements. The present study aimed to characterize such types of congenital anomalies in Tikrit governorate (Iraq). A total of 180 file records of newborn babies were allocated for those babies who have been admitted to the hospital after birth due to their requirement for help as a consequence of their diagnosis of congenital anomalies...

BACKGROUND: Chronic shoulder pain is a common musculoskeletal problem associated with unreleased pain and functional dysfunction that can evolve into central sensitization. Some forms of manual therapy may exacerbate pain and central sensitization. This study investigated the impact of joint position sense therapy (JPST), a moderate joint proprioception training technique, on central sensitization, shoulder functional dysfunction, and pain in patients with chronic shoulder pain compared with more intense exercises or aggressive manual therapies...

Differences between occupational groups are also examined. METHODS: The study is based on data from the statutory health insurance provider AOK Lower Saxony (N = 2,001,225)...

Shear wave elastography (SWE) is an emerging and promising ultrasound modality, and is more recently employed in the diagnosis of musculoskeletal (MSK) pathologies. SWE evaluates tissue stiffness by measuring the speed of propagating acoustic waves through body tissue structures. Knowing the variations in stiffness of MSK soft tissue can provide helpful diagnostic insight for the evaluation of pathology in muscles, tendons, ligaments, nerves, and other soft tissues. The goal of this review is to synthesize recent literature on the utility of SWE for MSK pathology diagnosis...
