ABSTRACT
In daily medical work, most of the critically ill patients who cannot move by themselves are pulled and lifted by manpower, often relying on the cooperation of many doctors and nurses, which not only increases the risk of transfer and patients' discomfort, but also causes certain skeletal and muscle damage to the porters. The emergency department of the First Hospital of Jiaxing City, Zhejiang Province designed a kind of patient transfer device, and obtained the National Utility Model Patent (ZL 2018 2 0579844.X). The transfer device is composed of upper frame, lower frame and base. The upper frame and the lower frame are rectangular and in a horizontal position. The upper frame can slide laterally through the circular tubes which are fixed on the lower frame. The lower part of the base is provided with four universal foot brake wheels. During the usage, the booster frame facilitates the transfer of patients by the rolling and two sliding tracks of the circular tube, which can make patients move smoothly and comfortably, and reduce the working intensity of the transporter. This device has good practical value.

ABSTRACT
OBJECTIVE: To observe the therapeutic effect of work intensive training on workers with musculoskeletal injury(MSI). METHODS: A convenience sampling method was used to select MSI patients as research subjects. Patients were randomly divided into control group(179 cases) and experimental group(188 cases). On the basis of the conventional comprehensive rehabilitation treatment, the control group received the routine occupational rehabilitation intervention, and the experimental group received the work intensive training intervention. The intervention period was 4 weeks in both groups. We used the Post-Traumatic Stress Disorder(PTSD) Self-Rating Scale, the Fear-Avoidance Beliefs Questionnaire(FABQ) and the General Self-efficacy Scale(GSES) to assess the recovery of MSI patients. The statuses of return to work of patients were followed up by telephone after six months of discharge from hospital. RESULTS: Compared with the same group before intervention, the scores of PTSD, FABQ-P and FABQ-W in the control group and the experimental group decreased, and the score of GSES increased(P<0.01). After the intervention, the scores of PTSD, FABQ-P and FABQ-W in the experimental group were lower than those in the control group(P<0.01), and the score of GSES was higher than those in the control group(P<0.01). The rate of returning to work in the experimental group was higher than that in the control group(80.9% vs 59.2%, P<0.01). CONCLUSION: Work intensive training has curative effect on self-efficacy, physical activity, subjective pain, and post-traumatic stress disorder, and can improve the rate of resuming to work in patients with MSI.

ABSTRACT
Objective To investigate the prevalence and influencing factors of chronic musculoskeletal injury (CMI) among nursing staff of old-age welfare in Urumqi city, to find out the awareness and implementation of preventive measures for chronic musculoskeletal injury, and the demand on new life support technology. Methods This study looked after chronic musculoskeletal injury situation questionnaire, in April 2015 form 1st to 30th in urumqi 8 nursing work of old-age nursing staff to carry out the questionnaire. Results A total of the 200 old-age nursing staff, the effective response rate of 183 (91.5%). Old-age nursing researchers report in the past week have the CMI hair author 169 people (92.3%). Occurrence of CMI in gender, educational background, whether on the thought of leaving post was statistically different (χ2=8.36,16.14,14.05,P<0.05). Higher occurrence of CMI was found in the nursing process of showering and washing hair [81.4%(149/183)], transition between wheelchair and bed [63.9%(117/183)], and changing body position in bed [61.2%(112/183)]. The most common site of CMI occurrence were namely back [84.7%(155/183)], shoulder [54.1%(99/183)], lower limbs [35.0%(64/183)]and upper limbs [30.1%(55/183)].Only 31 (16.9%) knew new life support technology which can prevent and reduce CMI. 178(97.3%) reported having needs to use new life support technology, and 179 (97.8%) were willing to participate in relevant technology. Conclusions Prevalence of CMI among nursing staff of old-age welfare in Urumqi region was high. It was related to many factors. Most of nursing staff have needs on life support techniques. Measures should be taken to prevent and reduce the occurrence of CMI among nursing staff of old-age welfare to improve work efficiency.
ABSTRACT
Background: Netball injuries remain an area of concern for professional and recreational South African players. This study profiled the prevalence of acute musculoskeletal injuries among female adolescent non-elite recreational netball players in Kwa-Zulu Natal, South Africa. Materials and Methods: Data were collected from 413 high school players who participated in the Kwa-Zulu Natal Netball School league. Players completed a self-reporting questionnaire for demographic information, acute musculoskeletal injuries and training history, mechanism of injury, types and nature of symptom, and severity of pain during the previous 12 months. Results: Two hundred and fifty-eight (62.0%) players sustained acute musculoskeletal injuries, with the knee (31%) and ankle (23.7%) injuries being the most prevalent. The mechanisms producing the musculoskeletal injuries were poor landing (37.8%), being pushed by an opponent (22.7%), colliding with a team mate (20.8%) and rapid rotational movement (18.5%). The injured netballers have played netball for longer period of years than uninjured players (p<0.05). Conclusion: Netballers have a high prevalence of acute musculoskeletal injuries, which are predominant in the knee and ankle.
ABSTRACT
Objective To investigate the occupational musculoskeletal injury of nurses in a thirdgrade and A-level general hospital in Zhengzhou,and analyze the relationship between occupational musculoskeletal injury and presenteeism.Methods 460 nurses were surveyed with questionnaires by convenience sampling,including nurses' demographic data,Nordic Standardized Questionnaires and Work Limitations Questionnaire.Results The annual incidence rate of OMSI in nursing staff was 82.38％.The parts of body which had high annual incidence rate of nurses' OMSI were lower back,neck and shoulder.The rates of presenteeism for no OMSI,one part OMSI and two or more parts OMSI were 35.14％,52.60％ and 59.68％.The scores of work efficiency decrease were (2.02±1.26),(4.67±2.53),(7.31±3.42).Conclusions Nurses' occupational musculoskeletal injury can result in presenteeism.The more serious occupational musculoskeletal injury is,the higher incidence rate of presenteeism,the more critical the presenteeism is.
