Summary: The purpose of this study was to analyze the effect of lower extremity muscle strength on aerobic capacity in adults with cerebral palsy. The results showed that the muscle endurance of the knee joint and the muscle power of the hip joint were important factors in predicting the aerobic capacity of individuals with cerebral palsy.

Summary: This study found that electrodiagnostic tests are more useful than lower extremity isometric strength tests for determining the degree of nerve damage and prognosis in cauda equina syndromes. By measuring isometric strength and nerve conduction parameters, the precise neurological condition of patients can be identified and the degree of paralysis and disability can be evaluated, leading to the establishment of an appropriate rehabilitation treatment plan.

Summary: This study aimed to evaluate age-related differences in muscle morphology, function, and functional capability in healthy adults. The results showed negative correlations between age and muscle thickness, pennation angle, fascicle length, maximal displacement, grip strength, and the 1-min chair rise test, while positive correlations were observed between age and the echo intensity of the muscle and total contraction time. The differences in muscle health were noticeable at 50 years of age, and females had larger differences compared to males. Physical activity was suggested to mitigate the detrimental changes.

Summary: This study conducted a cross-sectional study on Chinese older adults and found that muscle strength plays a partial mediating role between mobility and cognitive function. This suggests that maintaining sufficient muscle strength is crucial for the mobility and cognitive function of older adults.

Summary: This study demonstrates that handheld dynamometry (HHD) is a reliable and valid alternative to traditional testing for assessing lower extremity strength in older adults. HHD measurements showed a high correlation and excellent concurrent validity with Biodex measurements. However, HHD systematically overestimated torque.

Summary: This study compared and analyzed the effects of mid- and low-frequency electromyostimulations on lower limb muscles. It found that using mid-frequency electromyostimulation was more effective in increasing muscle strength than low-frequency electromyostimulation, suggesting its potential in slowing down or preventing the progression of sarcopenia.

Summary: Using personalized musculoskeletal computer models to predict post-surgery walking function and custom pelvic prosthesis loading is an emerging method for making surgical and custom prosthesis design decisions in a more objective manner. This study developed a computational method for estimating unmeasured trunk muscle activations during walking using lower extremity muscle synergies. The proposed method can facilitate the prediction of post-surgery walking function and pelvic prosthesis loading, as well as provide objective evaluations for surgical and prosthesis design decisions.

Summary: The objective of this meta-analysis was to evaluate the effect of whole-body vibration training on lower limb motor function in children with cerebral palsy. Thirteen randomized-controlled trials were included in the analysis, and the results showed that whole-body vibration training could effectively improve the lower limb motor function of children with cerebral palsy.

Summary: The study aimed to identify the preoperative muscle composition variables associated with postoperative gait function in patients after total knee arthroplasty. It was found that the lean muscle mass area of the patellar muscles was closely correlated with postoperative gait function. The area ratio of ipsilateral lean muscle mass to the total patellar muscles could predict gait function after total knee arthroplasty.

Summary: This study aimed to investigate the effects of biofeedback equipment with a tilt sensor and a neck correction exercise program on balance control ability, proprioception, and craniovertebral angle (CVA) in young adults. The findings showed that the exercise program significantly improved the stability index in the eyes-closed state, while the biofeedback program resulted in improvement in left rotation and CVA. These results suggest that a neck correction exercise program that actively moves muscles may have a positive impact on balance control ability, and biofeedback equipment can enhance proprioception by preventing forward head posture (FHP).

Summary: This study examined the effects of dual-task exercise-based augmented reality (AR) on muscle strength, muscle endurance, balance ability, and flexibility among people with developmental disabilities. The results showed significant improvements in these areas after the intervention. It was also found that individuals with higher cognitive levels had more interest and motivation in the AR-based dual-task program.
