ABSTRACT
Gait adaptability refers to adjustments of gait to accomplish walking and to overcome environmental difficulties. According to the training environment, gait adaptability training in stroke rehabilitation can be divided into two categories: real environment and simulated environment. The simulated environment is divided into simple indoor and multimoding environment. Some technologies, such as virtual reality and augmented reality may provide safer and more efficient methods for gait adaptability training. Gait adaptability training can improve walking function and confidence of hemiplegic patients, and help them to return to community life and social participation.
ABSTRACT
Objective:To compare the short-term effects of hip muscles strengthening and quadriceps strengthening on knee osteoarthritis (KOA), and discuss the advantages of hip muscles strengthening. Methods:From October, 2015 to May, 2016, 42 old females with KOA were divided into two groups equally. They received hip strengthening (HS group) and quadriceps strengthening (QS group) for two weeks, respectively. The pain, stiffness and physical function scores of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were measured. Isokinetic strength peak torque (PT) was assessed for knee extensors and flexors, and 6-minute Walk Test was also evaluated. They were followed up two months later. Results:Before exercise, there was no significant difference in all the indexes between two groups (P > 0.05). Two weeks after exercise, the knee flexor PT (t = -4.038, P = 0.001) and 6-minute walk distance (t = -2.474, P = 0.022) increased in QS group; the pain, stiffness and physical function scores of WOMAC (t > 2.487, P < 0.05), the knee extensor and flexor PT (|t| > 6.370, P < 0.001), and 6-minute walk distance (t = -2.241, P = 0.037) improved in HS group; the scores of WOMAC were lower (t > 2.087, P < 0.05) and the knee extensor PT was higher (t = -5.028, P < 0.001) in HS group than in QS group. At two-months' follow-up, the drop-out rate was significantly lower in HS group than in QS group (χ2 = 13.480, P < 0.001). Conclusion:Hip muscles strengthening is a good choice for KOA in the early stage of treatment, which could avoid the pain in quadriceps training, increase quadriceps strength and improve physical function.

ABSTRACT
Repetitive transcranial magnetic stimulation (rTMS) can achieve neuroplasticity through repeated stimulation of specific cortex, and may be in the ways of inter-hemisphere inhibition or compensation, or both. The various combination of frequency, intensity and duration of stimulation may effect the upper limb function after stroke in different ways.
ABSTRACT
Objective:To explore systematic implementation of World Health Organization Family International Classifications (WHO-FICs) in the field of rehabilitation: the theoretical and policy framework at macro level, governance and management mechanism at meso level, and implementation modules at micro levels, respectively. Methods:The policy and theoretical framework of rehabilitation development was discussed based on the international rehabilitation policy documents of WHO, mainly as World Report on Disability, Global Action Plan on Disability and Rehabilitation in Health Service System. Protocol and roadmap of systematic implementation of WHO-FICs, including International Classification of Diseases (ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Intervention (ICHIβ-2) was proposed. Results:With the use of WHO-FICs, the theoretical and policy framework of rehabilitation was constructed, and the contents and principles of modern rehabilitation services were clarified at macro-level. Rehabilitation is an important part of health service, there are six building blocks: i.e. leadership and governance, financing, human resources for health, service providing, medical technology and health information system. It proposed to use knowledge management system of WHO-FICs, including the classification, nomenclature, definitions, descriptions, terminology and coding systems, to standardize rehabilitation evaluation and statistics. The management and governance system of rehabilitation should be implemented using WHO-FICs. Rehabilitation services are based on the bio-psycho-social model and implemented the principles of people-centered and functioning-oriented. The systematic implementation of WHO-FICs in rehabilitation abide by the model of "Evaluation (ICHI)－Evaluation, Description, Classification and Coding of Functioning (ICF)－Disease Classification, Diagnosis and Coding (ICD)－Rehabilitation Intervention (ICHI)", and with the standardized process of "Evaluation (Functioning and unmet needs)－Diagnose (Disease and Functioning)－Planning of Rehabilitation－Intervention－Evaluation of Outcome". The mic-modules of implementation of WHO-FICs in rehabilitation had been constructed. There were 28 categories of diseases, 7 categories of functioning and 6 categories of rehabilitation interventions in rehabilitation proposed by International Society of Physical and Rehabilitation Medicine. According to ICD-11 and ICF, it proposed to use WHO Disability Assessment Schedule 2.0 (WHODAS 2.0), Brief Model Disability Survey (MDS-B) and VB40 Generic Functioning Domains (VB40), and the ICF core-sets in evaluation of functioning and rehabilitation outcome. The implementation of WHO-FICs in management of medical records and reporting realized the standardized management of medical record, encoding of diseases, functioning and intervention, reporting of performance, and provided tools for billing, reimbursement and payment management of rehabilitation. It proposed to develop WHO-FICs based clinical data sets and big data to implement functioning-related Diagnosis Related Groups and case-mix statistics. Conclusion:With the systematic implementation of WHO-FICs in rehabilitation, the policy and theoretical framework at macro level had been developed. The mechanism of management and governance at meso level had been explored. The application modules and approaches at micro level had been established. A scientific and effective overall solution had been proposed to enhance the scientific, standardized, refined and informatization level, strengthen the level and governance capacity, and improve the quality, safety and the coverage of rehabilitation services.
ABSTRACT
Objective:To investigate the rehabilitation human resources in Shanghai. Methods:Based on World Health Orgnization Rehabilitation in Health Service System: Action Guide, Rehabilitation Information Collection Template of Supporting Tools for Systematic Assessment of Rehabilitation Status was implemented by Shanghai Rehabilitation Medical Association in accordance with the requirements of Shanghai Rehabilitation Treatment Quality Control Center to investigate the number and knowledge structure of rehabilitation-related practitioners in Shanghai. Results:Totally, 311 medical institutions were investigated and 254 institutions set up rehabilitation medicine department, accounting for 82.47%. There were 1414 rehabilitation practitioners and 528 registered rehabilitation physicians, accounting for 37.34%; among them, senior, intermediate and junior professional titles were 142 (26.89%), 262 (49.62%) and 124 (23.48%), respectively. There were 2668 rehabilitation therapists, among which the senior, intermediate and junior professional titles were 11 (0.41%), 461 (17.28%) and 2196 (82.31%), respectively. There were 1614 rehabilitation nurses, among which the senior, intermediate and junior professional titles were 13 (0.81%), 476 (29.49%) and 1125 (69.70%), respectively. There were 2.17 rehabilitation physicians, 11.11 rehabilitation therapists and 6.65 nurses per 100 000 population, which is nearly 1/5 of the international level. There were 121 institutions without rehabilitation medical practitioners and 40 multi-point rehabilitation medical practitioners. Conclusion:There is a big gap in rehabilitation physicians, therapists and nurses in Shanghai, compared with the international level. Based on the imperfect occupational series and qualification certification of physiotherapists, occupational therapists, speech therapists and other specialties, it is suggested to conduct targeted job training in multiple channels and forms, especially to strengthen standardized job training and rehabilitation transformation training for rehabilitation practitioners. It is needed to promote the standardized training of resident and specialist rehabilitation practitioners more quickly to meet the needs of clinical rehabilitation work.
ABSTRACT
Knee osteoarthritis is a common chronic degenerative disease in the elderly. Its occurrence and development are closely related to biomechanical factors. The force of knee joint is affected by different factors, such as joint morphology, lower limb alignment, muscle contractions, external load, soft tissue traction and so on. Due to the limitation of in vivo measurement, biomechanical parameters based on motion analysis techniques have been widely used in clinical research. At present, biomechanical parameters which are widely studied and applied in clinical research include knee adduction moment, knee adduction impulse, knee flexion moment, and knee varus thrust. It is important to observe the changes of knee joint biomechanical parameters during the occurrence and development of knee osteoarthritis for researching etiology, diagnosis, intervention and treatment.
ABSTRACT
Background@#Emerging evidences have indicated that the composition of gut microbiota was significantly influenced by central nervous system diseases. The digestion and metabolism disturbances of patients with amyotrophic lateral sclerosis (ALS) might be strongly associated with ALS; however, this has rarely been evaluated in these populations. This study was to evaluate bacterial and archaeal composition of gut flora and the corresponding metabolism performance of these micro-organisms in fecal samples of patients with ALS.@*Methods@#A comparative study was performed on the intestinal microbiota from eight patients with ALS and eight healthy individuals at Huadong Hospital during November 2017 to April 2018; meanwhile, the metabolite concentrations of human endotoxin, short-chain fatty acids (SCFA), NO2-N/NO3-N, and γ-aminobutyric acid were also evaluated by spectrophotometry methods. The correlations between intestinal microbiota and metabolite concentration were compared between the two groups using one-way analysis of variance; the relative abundance of beneficial and harmful micro-organisms in fecal samples was also analyzed.@*Results@#In general, the richness and evenness of bacterial and archaeal communities of healthy individuals were healthier than that of patients with ALS. The phylum Firmicutes/Bacteroidetes ratio, genus Methanobrevibacter showed an enhancive tendency in patients with ALS, whereas the relative abundance of beneficial micro-organisms (genera Faecalibacterium and Bacteroides) presented a significant decrease tendency in patients with ALS. In addition, the average concentrations of human endotoxin, SCFA, NO2-N/NO3-N, and γ-aminobutyric acid in patients with ALS and healthy individuals were 64.2 vs. 65.3 EU/mL, 57.5 vs. 55.3 μg/mL, 5.7 vs. 5.3 ng/mL, and 6.1 vs. 5.4 μmol/L, respectively, indicating that the digestion and metabolism functions of gastrointestinal tract of patients might decline with this disease.@*Conclusions@#The relative abundance of beneficial and harmful micro-organisms respectively showed decrease and increase tendency in patients with ALS.

ABSTRACT
Knee osteoarthritis (KOA) is a common chronic degenerative joint disease. Hip muscle training, with the advantage of convenience and non-invasion, has been attached great importance by people gradually. Hip muscle training may affect keen medial compartment load, the strength and the electromyography signal of the muscle around the knee joint, and strong hip abductor can protect cartilage, which leads to change the load of the knee joint, and alleviate clinical symptoms. This article reviewed the mechanism of hip muscle training for knee osteoarthritis from the views of biomechanical simulation and electromyography.

ABSTRACT
Objectives:To explore the impact of attentional distribution principle on balance and arithmetic ability when performing calculation-balance dual task. Methods:From October, 2016 to December, 2017, 20 healthy young subjects were selected, and asked to perform eyes opened + calculation and eyes closed + calculation tests under sitting position, and perform single leg standing + eyes opened, single leg standing + eyes closed, single leg standing + eyes opened+ calculation and single leg standing + eyes closed + calculation tests in the static balance instrument. The maximum displacement in mediolateral direction and anteroposterior direction of center of gravity, sway area and sway path length were recorded, as well as the accuracy of counting backwards in steps of seven. Results:The maximum displacement in mediolateral direction and anteroposterior direction, sway area, sway path length were significantly less when eyes opened than eyes closed (t > 8.775, P < 0.001). The maximum displacement in mediolateral direction and anteroposterior direction, and sway area were less when eyes closed during the dual task than single task (t > 2.276, P < 0.05). There was no statistical difference in the maximum displacement in mediolateral direction and anteroposterior direction, and sway area and sway path length when eyes opened during the dual task compared with single task (t < 1.379, P > 0.05). There was no significant difference in the calculation accuracy among the eyes opened + sitting group, the eyes closed + sitting group, the eyes opened + balance test group and the eyes closed + balance test groups (P > 0.05). Conclusion:The low-difficult cognitive dual task does not affect the balance stability and arithmetic ability through the attentional distribution principle, on the contrary, the arithmetic task improves the static balance ability of single leg standing when eyes closed, however, it has no effect on the static balance ability of single leg standing when eyes opened.

ABSTRACT
@#Hemiplegics after stroke are often disabled in sit-to-stand(STS).This article discussed the biomechanics of STS in the hemiplegic stroke patients,in terms of kinematics,kinetics and surface electromyography,and the rehabilitation for the stroke patients with STS dysfunction.It was found that the stability,duration,symmetry of support and degree and se-quence of muscular activation were different when the patients finished the STS task in three foot positions of natural, symmetrical and unaffected foot behind.The early STS rehabilitation training or other rehabilitation may improve the function of the hemiplegic lower extremity to prevent falls and apraxia.
ABSTRACT
Objective To determine key muscles during muscle strength training of patients with knee osteoarthritis (KOA) by studying the correlation of KOA symptoms and disease stages with knee extensor/flexor strength. Methods Ninety-nine community volunteers were recruited and stratified into healthy group, single KOA group, and bilateral KOA group. The relationship between isokinetic extensor/flexor strength and KOA symptom, full-body aerobic exercise capacity, joint function were analyzed by knee isokinetic muscle strength test, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), 6-minute walk test, and CS-30 test. ResultsKnee isokinetic extensor peak torque of the symptomatic leg was significantly lower than that of the asymptomatic leg in single KOA group. There were significant differences in knee isokinetic extensor/flexor peak torque of both the severe and mild symptomatic leg in bilateral KOA group. Knee isokinetic extensor peak torque in bilateral KOA group was significantly lower than that in healthy group. Knee isokinetic extensor/flexor peak torque of KOA patients was positively related to 6-minute walk test, CS-30 test, while negatively related to age. Knee isokinetic extensor peak torque was negatively related to pain score and physical function score of WOMAC. Conclusions Both knee extensor and flexor strength are related to KOA. Therefore, during KOA rehabilitation therapies, muscle training for knee extensors (particularly quadriceps femoris muscles) and knee flexors (hamstring muscles, gastrocnemius muscles) need to be valued.
ABSTRACT
@#Knee osteoarthritis (KOA) is a common degenerative joint disease. Biomechanics of lower extremity plays an important role in KOA. Foot progression angle, with the advantages of non-invasive, convenience, has been attached great importance by people gradually. Changing foot progression angle may effect the knee adduction torque, tibia rotation, muscle activity, which leads to change the load of the knee joint, and alleviate the pain, improve the function of knee joint and the quality of life of the patients.
