ABSTRACT
Objective:To observe and analyze the effect of double and single bridge exercise on the electromyographic activities of related core muscle groups in stroke patients, and to explore its rules and characteristics.Methods:A prospective cohort study was conducted on 40 stroke patients hospitalized in the Department of rehabilitation medicine, Hefei second people's Hospital, Anhui Province from March 2020 to May 2021.The surface electromyography (sEMG) instrument was used to collect the surface electromyographic signals of erector spinalis, rectus abdominis, gluteus maximus and biceps femoris during double and single bridge exercise, and the root mean square (RMS) and integrated electromyography (iEMG) of the time domain indexes were analyzed. The measurement data conforming to normal distribution was expressed in xˉ± s.The non normal distribution data was expressed in M (Q1, Q3). Wilcoxon rank sum test was used to compare the difference between the two groups. Results:There was significant difference between RMS (30.0 (21.3, 45.5) μV vs. 24.0 (14.0, 35.8) μV) and IEMG (15.5. (10.0, 23.0) μV?s vs. 9.0 (5.0, 13.0) μV?s s) values of gluteus maximus on the healthy side and the affected side during double bridge exercise ( Z values were 2.07, 4.19; P values were 0.039, <0.001, respectively). There was significant difference in RMS (31.0 (15.3, 70.0) μV ratio of the healthy and affected biceps femoris 17.0 (11.0, 28.8) μV) and IEMG (14.5 (8.0, 26.5) μV?s vs. 7.0 (5.0, 10.8) μV?s) values of biceps femoris on the healthy side during double bridge exercise ( Z values were 3.44, 3.64; P values were 0.001 and <0.001, respectively ). There was significant difference between RMS(38.5(32.3, 46.0) μV vs. 35.0(22.3, 43.0) μV) and IEMG (16.5(12.0, 22.8) μV?s vs. 12.0(7.0, 21.0) μV?s) values of the gluteus maximus on the healthy side during single bridge exercise ( Z values were 2.24, 2.45; P values were 0.025, 0.014, respectively). There was significant difference between RMS (38.0 (15.3, 70.0) μV vs. 19.0 (12.0, 35.5) μV) and IEMG (16.0 (10.0, 27.0) μV?s vs. 6.5 (5.0, 12.5) μV?s s) values of biceps femoris on the healthy side during single bridge exercise ( Z values were 2.98,4.34; P values were 0.003 and <0.001, respectively). There was significant difference between RMS (24.0 (14.0, 35.8) μV vs. 35.0 (22.3, 43.0) μV) and IEMG (9.0 (5.0, 13.0) μV?s vs. 12.0 (7.0, 21.0) μV?s) values of double and single gluteus maximus on the affected side ( Z values were 2.24, 1.99; P values were 0.025,0.047, respectively). Conclusion:Double bridge and single bridge exercise could improve the related core muscle groups of stroke patients with hemiplegia, and single bridge was better than double bridge for the activation of gluteus maximus
ABSTRACT
Objective To explore the feasibility and effectiveness of lateral gastrocnemius muscle branch nerve transferring for deep pe-roneal nerve injury. Methods Thirty-two adult female Sprague-Dawley rats were divided into control group (n=8), sham group (n=8), nerve direct repairing group (n=8) and nerve transferring group (n=8). Twelve weeks after the anastomosis, the nerve anastomosis was observed vi-sually, the length of lateral of gastrocnemius muscle branch (L1), the diameter at the point of entering muscle (D1), the maximum detachable length of nervus peroneus communis (L2), the diameter of deep peroneal nerve (D2) and the distance between branch point and neck of fibu-la (S) were measured. The peroneal nerve functional index (PFI), the amplitude of compound muscle action potential (CMAP), nerve con-duction velocity (NCV), the weight of the tibialis anterior and the creatine kinase (CK) activity of theanterior tibial were compared among groups. Results L10.05). Conclusion It is feasible that lateral head muscular branches of gastrocnemius nerve transferring can repair deep peroneal nerve injury, which is needed to separate superficial peroneal nerve and deep peroneal nerve in the epineurium without damaging nerve for tension free neuroanastomosis. Lateral head muscular branches of gastrocnemius nerve transferring can repair the func-tion after deep peroneal nerve injury.
ABSTRACT
Diffusion tensor imaging (DTI), which responds with the diffusion of water molecules in spinal cord white matter, may be used to detect the integrity of the spinal cord fiber bundles and the pathological changes after injury. It is sensitive in acute and chronic spi-nal cord injury, such as cervical spondylotic myelopathy, multiple sclerosis, brain damage secondary spinal cord injury, spinal nerve root damage, and so on. In basic studies, DTI can reveal the microstructure and pathological changes of the injured spinal, and be correlated with behavioral assessment, which involved mice, monkeys, calves, cats, swines, dogs, and so on.

ABSTRACT
@#Objective To explore the effect of salmon calcitonin on osteoporosis induced by spinal cord injury. Methods 100 patients with osteoporosis induced by spinal cord injury from September 2011 to September 2014 in our department were included. They were randomly divided into control group (n=50) and observation group (n=50). The control group received vitamin D3 only, while the observation group received vitamin D3 combined with salmon calcitonin on the basis of rehabilitation physiotherapy, for 6 months. Visual Analogue Scale (VAS) of pain was evaluated in different periods. The bone mineral density (BMD) of lumbar spine and femoral neck, the parathyroid hormone (PTH), bone gla protein (BGP) and 1,25- dihydroxy vitamin D3 (1,25-(OH)2D3) were tested and recorded. Results The VAS score was lower in the observation group than in the control group 1, 2, 3 and 6 months after treatment (P<0.001). The BMD of lumbar spine and femoral neck was significantly higher, the PTH and BGP were significantly lower and the 1,25-(OH)2D3 was significantly higher in the observation group than in the control group after treatment (P<0.001). Conclusion Combination of salmon calcitonin can effectively reduce the bone pain and improve the BMD in patients with osteoporosis induced by spinal cord injury.
