BACKGROUND: Osteoporosis is increasingly threatening the elderly survival quality and life. Numerous studies have shown that the vibration training is a new method to improve osteoporosis. OBJECTIVE: To overview the effect of vibration training on the skeletal system, and provide a new idea for osteoporosis prevention. METHODS: The first author searched the PubMed and CNKI databases using the following format: (Vibration training [Title]) OR (Vibration mode [Title]) OR (Vibration pattern [Title]) and (“Vibration training” [Title]) or (“Vibration mode”[Title]) in English and Chinese, respectively, in April 2015. Finally, 38 eligible articles were included according to their titles and abstracts. RESULTS AND CONCLUSION: Bases on overseas and domestic researches about the effect of whole body vibration on the skeletal system, we summarize the mechanical load, vibration stress principles and outcomes of whole body vibration training as well as factors involvied in osteoporosis such as the stimulation site, stimulation type, exercise load, exercise duration and vibration frequency. In addition, the safety of vibration training and its preceding studies are also generalized. These results suggest that elderly osteoporosis can be improved through the vibratory equipment. We can improve bone loss and living quality of the elderly by vibration at different frequencies and duration thresholds vibration at using the vibratory equipment. © 2016, Journal of Clinical Rehabilitative Tissue Engineering Research.

An experiment was carried out in the key laboratory for Technique Diagnosis and Function As-sessment of Winter Sports of China to investigate the differences in gait characteristics between healthy children and children with spastic hemiplegic cerebral palsy. With permission of their parents, 200 healthy children aged 3 to 6 years in the kindergarten of Northeastern University were enrolled in this experiment. Twenty children aged 3 to 6 years with spastic hemiplegic ce-rebral palsy from Shengjing Hospital, China were also enrolled in this experiment. Standard data were collected by simultaneously recording gait information from two digital cameras. DVracker was used to analyze the standard data. The children with hemiplegic cerebral palsy had a longer gait cycle, slower walking speed, and longer support phase than did the healthy children. The support phase was longer than the swing phase in the children with hemiplegic cerebral palsy. There were significant differences in the angles of the hip, knee, and ankle joint between children with cerebral palsy and healthy children at the moment of touching the ground and buffering, and during pedal extension. Children with hemiplegic cerebral palsy had poor motor coordination during walking, which basically resulted in a short stride, high stride frequency to maintain speed, more obvious swing, and poor stability.

Inflammation plays a crucial role in the pathogenesis and prognosis of stroke. This study aims to investigate the relationship between acute ischemic stroke (AIS) and lipoprotein(a) [Lp(a)] levels and to determine the prognosis value of Lp(a) to predict the functional outcome. A total of 153 patients with AIS and 120 controls were included in the study. Serum Lp(a) levels were examined in both groups. Severity of the stroke was assessed using the National Institutes of Health Stroke Scale. The modified Rankin Scale scores at discharge were determined to establish the prognosis of stroke patients. The prognostic value of Lp(a) to predict the functional outcome within the time of discharge was analyzed by logistic regression analysis, after adjusting for the possible confounders. The results indicated that the serum Lp(a) levels were significantly higher in AIS patients as compared with normal controls [303 {interquartile range (IQR) 170-529 mg/l} and 144 (IQR 66-252 mg/l), respectively; P=0.000]. In the 52 patients with an unfavorable functional outcome, serum Lp(a) levels were higher compared with those in patients with a favorable outcome [213 (IQR 143-347 mg/l) and 559 (IQR 357-845 mg/l), respectively; P=0.000]. In multivariate analysis, there was an increased risk of unfavorable outcome associated with Lp(a) levels 300 mg/l or more (odds ratio 3.12; 95% confidence interval 1.55-5.28; P=0.001) after adjusting for possible confounders. Serum Lp(a) can be considered as an independent short-term prognostic marker of functional outcome in Chinese patients with AIS even after correcting for possible confounding factors.


BACKGROUND: Research on the mechanism underlying aerobic exercise improving cognitive function of rats with vascular dementia mainly focuses on behavioral observation and indicator detection in the hippocampus in vitro; however, there is a lack of in vivo experiments in view of the sensory and prefrontal cortex. METHODS/DESIGN: A randomized controlled animal experiment has been designed. Based on the synchronous nerve electrophysiology recording developed by our research group, the experiment is designed as follows: rats are trained firstly to make different reactions to different sounds, and are then modeled into vascular dementia. There are normal, vascular dementia, and vascular dementia undergoing short-, median-, and long-term aerobic exercise (treadmill/wheel) rats. Afterwards, the implantable microelectrodes are implanted into the auditory and prefrontal cortex, followed by the cognitive behavior training. The characters of rat cognitive behavior are observed, the electrical activity of sensory and prefrontal cortical neurons are recorded synchronously, the cortical experiment at molecular level is performed and the ultrastructure of brain tissue is observed. RESULTS AND CONCLUSION: This study investigates the cortical mechanism by which aerobic exercise improves the cognitive function of vascular dementia rats utilizing etiology, electrophysiology, molecular biology and histological technologies, aiming at providing feasible ideas for the diagnosis and treatment of relative mental and nervous system diseases. ETHICAL APPROVAL: This study was approved by the Ethics Committee of Shenyang Sport University. The disposal of rats was in line with the Guideline for the Care and Use of Laboratory Animals and the Guideline of USA National Institutes of Health. © 2016, Journal of Clinical Rehabilitative Tissue Engineering Research.

BACKGROUND: Women who wear high heels often feel discomfort that will become a potential killer; therefore, it is impending to figure out how the heel height affecting walking gait features and the biomechanics mechanism. OBJECTIVE: To investigate the walking gait features of adult women with different body mass indexes wearing different height heels. METHODS: Based on the body mass index, 20 adult women were divided into two groups: overweight and criterion groups. The walking gait features when they in flat shoes or in different height high heels were detected using three-dimensional video analysis system and plantar pressure test system, and kinematics and kinetic parameters were collected. RESULTS AND CONCLUSION: (1) Walking gait characteristics were normal when overweight subjects (24 kg/m2 ≤ body mass index < 28 kg/m2) in high heels with height lower than 5.3 cm; for criterion subjects (18.5 kg/m2 ≤ body mass index < 24 kg/m2, the heels height should be lower than 6.5 cm. The obviously abnormal walking gait features were visible in 8.5 cm high heels in the two groups. (2) The peak pressure intensity of the first, second and third metatarsal bones increased with heel height increasing, while the fifth metatarsal bone peak pressure showed a negative correlation with the height. © 2016, Journal of Clinical Rehabilitative Tissue Engineering Research.

BACKGROUND: The gymnastic skill training of juveniles tends to be scientific and systematic, such as confirming the strength characteristics of joints and muscles and implementing training program pertinently based on the scientific diagnostic method. OBJECTIVE: To explore the isokinetic muscle strength characteristics of the trunk, hips and knees in juvenile male gymnasts. METHODS: Sixteen juvenile male gymnasts who were active athletes in Liaoning province were enrolled. ISOMED2000 isokinetic muscle strength test system was used to detect the muscle strength, and the test speed of trunk set as 30, 60 and 180 (°)/s, while 60, 180 and 300 (°)/s for the hips and knees. RESULTS AND CONCLUSION: At 30, 60 and 180 (°)/s, the hamstring/quadriceps ratio of trunk were 91.36±1.25, 87.77±3.74 and 78.20±4.70, respectively. At 60, 180 and 300 (°)/s, the hamstring/quadriceps ratio of the left hip was 65.55±4.38, 66.92±3.22 and 68.18±2.82, while that of the right hip were 57.40±4.43, 65.73±1.07 and 64.15±5.55. Additionally, the left flexor strength was significantly higher than that of the right, while the right extensor strength was significantly higher than that of the left at 60 (°)/s (P < 0.05). At 60, 180 and 300 (°)/s, the hamstring/quadriceps ratio was 50.88±4.98, 54.75±4.51 and 58.80±7.93 for the left knee, and 51.55±4.30, 55.20±5.08 and 58.43±5.93 for the right knee. In three test speeds there were no significant differences in flexor and extensor strength between two sides (P > 0.05). These results indicate that the rapid strength of the back especially of the flexor is insufficient markedly, and the basic strength of the extensor is weak. The basic strength of the left flexor in the hip is large, the same as the right extensor; the rapid strength of flexor is weak, and imbalance in the muscle strength between two sides appears. Fortunately, the muscle strength of the knee between two sides achieves balance, but there is still a certain deficiency in the rapid strength of the left flexor and the basic strength of the extensor on both sides. © 2016, Journal of Clinical Rehabilitative Tissue Engineering Research.

In order to obtain the Lower Muscle Strength Feature for Elite Speed Skaters in High Speed Gliding, this paper applied video analysis and isokinetic testing methods to conduct kinematic and kinetics dates. Contrasting to the kinematics dates, torques were computed by the Newton interpolation polynomial, which are simulated as the actual moments during gliding. According to the experimental results, the sLower Muscle Strength Feature is unique and correct. The larger of the velocity, the less moments produced from the hip, knee and ankle muscular, which will do harm to the power output.
