ABSTRACT
BACKGROUND: Far-infrared wave therapy can accelerate blood flow rapidly, strengthen the exchange of substance and energy among tissues, and promote the rapid recovery of musculoskeletal micro-injury. The far-infrared ceramic microsphere is a new functional rehabilitation material in the field of physical therapy and rehabilitation in recent years. OBJECTIVE: To verify the therapeutic effectiveness of far-infrared ceramic microsphere intervention on muscle extensibility, stiffness, and elasticity after musculoskeletal injury. METHODS: Male students aged 18-21 years who were diagnosed with posterior femoral muscle injury in each sports specialty were selected as test subjects. Twenty subjects were selected and randomly divided into two groups (n=10/group), and then underwent far-infrared therapeutic apparatus (control group) and far-infrared ceramic microsphere intervention treatment (trial group) for 2 consecutive weeks. A non-invasive muscle detection system was used to collect muscle extensibility, muscle stiffness, and muscle elasticity data before and 3, 7, and 14 days after treatment. RESULTS AND CONCLUSION: (1) The muscle extensibility in the trial group at 3, 7, and 14 days after treatment was higher than that before treatment (P 0.05). In the control group, the muscle extensibility at 14 days after treatment was higher than that before treatment (P 0.05). In the control group, the muscle stiffness at 14 days after treatment was higher than that before treatment (P 0.05). In the control group, the muscle elasticity at 14 days after treatment was higher than that before treatment (P < 0.05), but it was still lower than that of the healthy side (P < 0.05). The muscle elasticity at different time points in the trial group was higher than that in the control group (P < 0.05, P < 0.01). (4) In summary, far-infrared ceramic microspheres can improve muscle extensibility and elasticity, reduce muscle stiffness and promote the recovery of muscle damage.
ABSTRACT
BACKGROUND: Recently, as an independent fracture factor from Bone mineral density (BMD), muscle weakness due to the fatty degeneration of thigh muscles have been attracting attentions as causes of hip fracture. The purpose of this study is to investigate the correlation between the body composition and BMD and fatty degeneration of thigh muscles of the female patients over 65 years old with osteoporotic hip fracture. METHODS: This study was conducted with 178 female osteoporotic hip fracture patients. Total hip BMD was measured using dual energy X-ray absorptiometry. Cross-sectional area (CSA), cross-sectional muscle area (CSmA), muscle attenuation coefficient (MAC), and intramuscular adipose tissue (IMAT) of gluteus maximus, hip abductors, quadriceps and hamstring muscle were measured with computed tomography. Normalized IMAT (nIMAT) was calculated by dividing the fat area in the muscle into the size of each muscle. The correlation between each measurement is examined then the differences between the intertrochanteric fracture group and the femoral neck fracture group were analyzed. RESULTS: CSmA and MAC of quadriceps were the largest and nIMAT was the lowest. CSA and CSmA of the four muscles showed a statistically significant positive correlation with weight, height, body mass index (BMI), and BMD. MAC of 2 gluteal muscles was positively correlated with weight, BMI and BMD. nIMAT of all four muscles was positively correlation with weight and BMI but nIMAT of 2 mid-thigh muscles was positively correlation with BMD. CONCLUSIONS: Muscle size and fatty degeneration in the thigh muscles were most positively correlated with the body weight. BMD was positively correlation with CSA and CSmA of all thigh muscles, and MAC of 2 gluteal muscles and fatty degeneration of 2 mid-thigh muscles. There was no statistically significant difference in the size of the femoral muscle and the degree of fatty degeneration between the two fracture groups.
