Biomechanical coordination and variability alters following repetitive movement fatigue in overhead athletes with painful shoulder.
Sci Rep

Department of Sport Biomechanics, Faculty of Sports Sciences, Bu-Ali Sina University, Hamedan, Iran.
Most sports and leisure activities involve repetitive movements in the upper limb, which are typically linked to pain and discomfort in the neck and shoulder area. Movement variability is generally expressed by changes in movement parameters from one movement to another and is a time-dependent feature of repetitive activities. The purpose of this study was to examine the effect of repeated movement-induced fatigue on biomechanical coordination and variability in athletes with and without chronic shoulder pain (CSP).

Common fibular nerve (CFN) palsy is the most common mononeuropathy in the lower limb, and several etiologies are described. The CFN is the minor and lateral division of the sciatic nerve; it originates in the lumbar sacral division, and many risks of compression have been described: the behavior of crossing and squatting legs, extra and intraneural compressions, local trauma, and weight loss have been increasingly reported as important and noteworthy causes. The treatment is based on the severity of the nerve condition.

Article Synopsis
- The study aimed to evaluate the safety and effectiveness of Relatox, a type of botulinum toxin, in treating focal spasticity of the upper limb caused by cerebrovascular accidents or traumatic brain injuries.
- It involved 210 patients divided into two groups; one received Relatox injections, while the other received Dysport. Both groups showed a reduction in spasticity over 12 weeks, with no significant differences between the two treatments.
- Various measurements were used to assess spasticity, disability, pain, and treatment satisfaction, and both medications were found to be effective, with a report on adverse events collected throughout the study.
Effects of age/gender profiles and physical activity level on symmetry of lumbar muscle activation in pain-free older adults during various spinal movements.

Department of Orthopedic Surgery, Division of Orthopedic Research, Mayo Clinic, Rochester, MN, USA. Electronic address:
Background: Back muscles simultaneously drive spinal movements and stabilize the trunk. Paraspinal muscle activity is presumed to be symmetric and gender-insensitive, and more activated with aging to protect the spine during functional tasks.
Research Question: Does over-activated and asymmetric behaviors exist in the pain-free elderly population which is affected by their physical activity levels?
Methods: Forty healthy participants (aged 64.
Role of forelimb morphology in muscle sensorimotor functions during locomotion in the cat.

School of Biological Sciences, Georgia Institute of Technology, Atlanta, GA, USA.
Article Synopsis
- Previous research has highlighted the importance of hindlimb muscle morphology in locomotion, but the role of forelimb muscle structure in motor outputs and sensory signal generation is less understood.
- This study measured the morphological features of 46 forelimb muscles in cats and analyzed their function during different types of locomotion, revealing significant relationships between muscle characteristics and force production.
- Results indicate that forelimb muscle morphology plays a vital role in controlling lateral stability and turning movements, emphasizing its importance beyond just propulsion in locomotion.
