This study aims to introduce the protocol for ultrasonic backscatter measurements of musculoskeletal properties based on a novel ultrasonic backscatter bone diagnostic(UBBD)instrument.Dual-energy X-ray absorptiometry(DXA)can be adopted to measure bone mineral density(BMD)in the hip,spine,legs and the whole body.The muscle and fat mass in the legs and the whole body can be also calculated by DXA body composition analysis.Based on the proposed protocol for backscatter measurements by UBBD,ultrasonic backscatter signals can be measured in vivo,deriving three backscatter parameters[apparent integral backscatter(AIB),backscatter signal peak amplitude(BSPA)and the corresponding arrival time(BSPT)].AIB may provide important diagnostic information about bone properties.BSPA and BSPT may be important indicators of muscle and fat properties.The standardized backscatter measurement protocol of the UBBD instrument may have the potential to evaluate musculoskeletal characteristics,providing help for promoting the application of the backscatter technique in the clinical diagnosis of musculoskeletal disorders(MSDs),such as osteoporosis and muscular atrophy.

BACKGROUND： Musicians are frequently affected by playing-related musculoskeletal disorders （PRMD）. Common solutions used by Western medicine to treat musculoskeletal pain include rehabilitation programs and drugs, but their results are sometimes disappointing. OBJECTIVE： To study the effects of self-administered exercises based on Tuina techniques on the pain intensity caused by PRMD of professional orchestra musicians, using numeric visual scale （NVS）. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS： We performed a prospective, controlled single-blinded, randomized study with musicians suffering from PRMD. Participating musicians were randomly distributed into the experimental （n = 39） and the control （n = 30） groups. After an individual diagnostic assessment, specific Tuina self-administered exercises were developed and taught to the participants. Musicians were instructed to repeat the exercises every day for 3 weeks. MAIN OUTCOME MEASURES： Pain intensity was measured by NVS before the intervention and after 1, 3, 5, 10, 15 and 20 d of treatment. The procedure was the same for the control group, however the Tuina exercises were executed in points away from the commonly-used acupuncture points. RESULTS： In the treatment group, but not the control group, pain intensity was significantly reduced on days 1, 3, 5, 10, 15 and 20. CONCLUSION： The results obtained are consistent with the hypothesis that self-administered exercises based on Tuina techniques could help professional musicians controlling the pain caused by PRMD. Although our results are very promising, further studies are needed employing a larger sample size and double blinding designs.

Introduction: musculoskeletal disorders (MSDs) are a set of peri-articular conditions that result mainly in pain and functional discomfort. They represent a major occupational health problem in all areas of activity. The objective of this work was to determine the prevalence of MSDs among street vendors in the city of Bangui in the Central African Republic (CAR). Methods: A cross-sectional study was conducted from September 01 to October 31, 2021 in Bangui, the capital of CAR. The study population consisted of street vendors which were included at the entrance of 4 large markets of Bangui after giving informed consent. The sample size, calculated according to the Schwartz formula, was 384. Sociodemographic data (age, gender, level of education, marital status), professional data (the duration of sale in hours, the distance traveled per day);and health data (the health problems suffered by itinerant sellers and the means of dealing with them) were collected using a pre-established self-questionnaire. This collected data was processed using Microsoft Excel 2013 and Epi-Info version 7 software. Results: Among 384 street vendors included, women represented a quarter (24.9%). The average age was 27 years;the 25-34 age group was the most represented (50%). About two-thirds (64.8%) sold for at least 12 hours and traveled more than 10 km (69.3%) per day. The main health problems reported by street vendors were musculoskeletal disorders (95.8%). Their locations concerned the upper limbs shoulder 65.36% (251), elbow 24.22% (93). Non-ergonomic postures that stress the back and joints all day long, causing pain are risk factors for MSDs. These MSDs were treated by self-medication with non-steroidal anti-inflammatory drugs (22.0%), mainly sold on the street. Conclusion: MSDs dominated the health problems of street vendors. These problems raise the need for recognition and support for these workers to optimize their performance while preserving their health through awareness and good management of MSDs whose chronicity generat

Degenerative musculoskeletal disorders are one of the top causes of pain and disability in the adult population.Current available alternatives to mitigate symptoms include conservative treatments such as the administration of pharmacological agents and an educative approach towards lifestyle modification.The use of certain analgesics,such as opiates and corticosteroids,delivers short term results but do not address the etiological source of pain and disability.Also,prolonged use of such medications may cause additional complications.Therefore,the demand for musculoskeletal tissue regeneration has led to an alternative approach referred to as“orthobiologics”.This alternative is based on cellular and molecular components capable of inducing and promoting tissue repair.Bone marrow(BM)aspirate(BMA)and concentrate are well-known orthobiologics used to treat musculoskeletal conditions.Orthobiologics derived from the BM have been discussed in the literature;however,the lack of standardization regarding collection and processing protocols presents a challenge for generalization of study outcomes and determination of efficacy.Since BM-derived orthobiologics have not yet been classified,to our knowledge,this manuscript proposes the ACH classification system,which speaks to BMA(A),BMA and concentrate(C)and hybrid(H),which combines A and C.This classification proposes and describes 8 parameters that are relevant for the quality of biological products.The more parameters used would imply greater characterization and complexity of the evaluation of the biological product used.The ACH classification envisages a necessary contribution to the comprehension of both clinical procedures and research outcomes,ultimately ushering in a standardization of best practice.

Among degenerative musculoskeletal disorders,osteoarthritis remains one of the main causes of pain and disability in the adult population.Current available alternatives to alleviate symptoms include conservative treatments such as physical therapy,anti-inflammatory drugs and an educational approach to lifestyle modification.The use of certain analgesics,such as opiates and corticosteroids offer short-term results but does not address the etiological source of pain and disability.In addition,prolonged use of such medications can cause additional complications.Therefore,the demand for regeneration of joint cartilage has led to an alternative approach called"orthobiologics".This alternative is based on cellular and molecular components capable of inducing and promoting tissue repair.Products derived from adipose tissue have been studied as an excellent source of orthobiologics in an attempt to promote joint cartilage repair.However,the lack of standardization regarding collection and processing protocols presents a challenge for the generalization of study results and determination of effectiveness.To the best of our knowledge,orthobiologics derived from fat have not yet been classified.Therefore,this manuscript proposes the HGS classification system which aims to describe certain parameters that are relevant to the quality of organic products regarding harvesting techniques(H),graft type(G),and number of centrifugations(S).The more parameters used would imply greater characterization and complexity of the evaluation of the biological product used.The HGS classification may provide a valuable contribution to the understanding of clinical procedures and research results,aiming to ultimately usher in a standardization of optimal practice.

作者： Cristiane Assuncao da Costa Cunha Iris do Ceu Clara Costa Angelo Giuseppe Roncalli Dyego Leandro Bezerra de Souza Fábia Barbosa de Andrade Antonio Medeiros Júnior Department of Dentistry Federal University of Rio Grande do Norte(UFRN)NatalBrazil Department of Collective Health Federal University of Rio Grande do Norte(UFRN)NatalBrazil Department of Nursing Faculty of Health Sciences of Trairi(FACISA)Federal University of Rio Grande do Norte(UFRN)Santa CruzBrazil

Objectives: Identification of the level of knowledge on ergonomics principles, and application of these by dentistry students to investigate whether painful symptomatology was experienced. An-other objective is the expansion of discussions on occupational health in academic settings. Study Design and Settings: Dentistry students of the Federal University of Rio Grande do Norte, Brazil (n = 148) were surveyed using the Nordic musculoskeletal Questionnaire to determine the severity of musculoskeletal symptoms experienced. Data were analyzed through EpiInfo 7.0 to measure central trends and variability 5for quantitative variables, absolute and relative frequencies for categorical variables, and significance between groups (confidence intervals and chisquare). Association analysis (Pearson) was also carried out. Results: Ergonomic measures were not reported by students. Within the musculoskeletal symptoms described, females were the most affected, independent of academic level. Conclusions: Positive correlations were verified between all categories and all anatomic regions (e.g., neck, lower back, wrists, hands, and shoulders). Data suggest progressive worsening of symptoms, which will eventually result in leaves of absence.

＜正＞Work related musculoskeletal disorder （WMSD） is regarded as a major health problem amongst workers in industries today. Often it is caused by unsuitable design of workplaces. This paper presents the results of anthropometries data of industrial workers collected from various types of industries in Malaysia. The resulting data is compared with existing data from Japan and US that are often used for designing workplaces, task and equipment in Malaysian industries. The results had revealed some significant differences between certain body dimensions. These differences may be the cause of unnecessary strain or injuries experienced by the workers. The data can be used for improving workplace;task and equipment that is more suited towards the Malaysian workers and may prove crucial in reducing related injuries and illness.
