ABSTRACT
Background Neck-shoulder pain is one of the most common discomfort symptoms among nursing staff, mostly caused by a heavy workload, restricted workstation, and prolonged poor posture. Objective To investigate the prevalence of neck-shoulder pain among nursing staff in tertiary general hospitals in Hunan Province, and to analyze workload-related risk factors. Methods From October to December 2018, a multi-stage stratified randomized cluster sampling method was adopted to select a total of 1 200 nursing staff who met the inclusion andexclusion criteria in six tertiary general hospitals from five geographic subdivisions of Hunan Province were selected. A self-designed questionnaire was used to collect demographic characteristics, and past 1-month prevalence of neck-shoulder pain, a neck disability index (NDI) was used to assess the impact of neck pain on daily life, and functional disability was graded by the index of impaired neck function; a self-designed questionnaire was adopted to evaluate potential workload-related risk factors (working time, postural load, and force load) of neck-shoulder pain after a Delphi expert consultation. A total of 1 161 valid questionnaires were returned, and χ２test and logistic regression model were used to screen the potential risk factors for neck-shoulder pain. Results The prevalence rate of neck-shoulder pain in the past 1 month was 87.5% (1 016/1 161) and varied by different characteristics of the nursing staff, ranging from 76.9% to 91.2%. The scores of the 10 items of the NDI ranged from 0 to 5, but most of them were 0, 1, and 2; of the 10 items, neck pain had the greatest impact on sleep (1.30±1.21) and the least impact on self-care behaviors (0.35±0.65). The index of impaired neck function showed that the majority (65.4%) of nurses had mild cervical spine dysfunction and 30.1% had moderate cervical spine dysfunction. The univariate analysis results revealed that 24 out of the 31 workload-related risk factors had significant differences, and further multiple analysis results showed that three variables entered the logistic regression model. Under the same conditions, nurses with ≥5 h of cumulative head-down tasks per shift had 3.03 times higher neck-shoulder pain risks compared with those with ＜1 h. Compared with “occasionally or never”, nurses who “sometimes” and “often” tilted their necks back and maintained this posture for a long time showed 2.36 and 2.94 times higher risks for neck-shoulder pain respectively. The nurses who reported “sometimes” and “often” having difficulty using their force at work due to unnatural posture had 2.78 times and 7.08 times higher neck-shoulder pain risks than those who “occasionally or never” respectively. Conclusion The reported rate of neck-shoulder pain among nurses in tertiary general hospitals in Hunan Province is high, but most of them are mild dysfunction. Working hours and posture load may affect the risk of neck-shoulder pain.
ABSTRACT
Objective To study the relations between neck/shoulder or low back pain and their daily behavioral habits among middle school students in Shenzhen.Methods We randomly chose 3 952 students from 10 high schools in Shenzhen to complete the questionnaires.Data was gathered and analyzed,using the IBM SPSS 23.0.Results Of the 3 952 participants,20.3％ had neck/shoulder pain and 15.2％ had low back pain.Among students experienced neck/shoulder pain,female (25.3％),high school (24.5％) and boarding students (24.4％) experienced higher rates of neck/shoulder pain (P＜0.05).Female students (17.9％) also had higher rate of low back pain (P＜0.05).Results from logistic regression analysis showed that factors as:gender,type of school,taking naps on the desk,staying up late,self-perceived stress from learning,overloading homework,time spent on mobile phone and TV,spending long time on computer etc.were related to the neck/shoulder pain (P＜0.05).Factors as:gender,naps on the desk,stay up late,self-perceived stress,overloading homework,time spent on mobile phone and TV etc.,were related to low back pain (P＜0.05).Conclusion Neck/shoulder pain and low back pain were both commonly seen while high self-perceived stress,sedentary behaviors and poor sleeping habits were associated with both neck/shoulder and low back pain in high school students in Shenzhen.

ABSTRACT
Objective To evaluate the effects of focal vibration on the physical properties and surface electroyograms of persons with neck-shoulder pain.Methods Thirty-four patients with neck-shoulder pain received 3 to 5 applications of vibratory stimulation of the inner side of the trapezius and scapula for 30 s each time.They reported their pain level using a visual analogue scale.Muscle tone and the elasticity and stiffness of the trapezius muscle were measured bilaterally using a MyotonPRO Muscular Function Evaluation System.Surface electromyography (sEMG) was performed bilaterally during arm extension while standing.The testing was repeated four times:before treatment (baseline),immediately after treatment (IAT),2 hours after treatment (2AT) and 6 hours after treatment (6AT).Results There was a significant reduction in reported pain at IAT and 2AT compared to baseline,but no significant difference was found between the perceived pain at baseline and at 6AT.The values of oscillation frequency,logarithmic decrement and dynamic stiffness had decreased significantly at IAT and 2AT compared to baseline.The average AEMG during upper-arm flexion of the trapezius on the painful side had increased significantly at IAT comparcd to that before the treatment,while the average IEMG and MF were both significantly higher than before the treatment.At 2AT the average AEMG and IEMG were both still significantly higher than at the baseline,but there was no longer a significant difference in the average MF.By 6AT none of the three indicators differed significantly from those before the treatment.Conclusions A single session of focal vibration can relieve pain,increase muscle activation as well as decrease muscle stiffness for people with neck-shoulder pain within 2 hours.
ABSTRACT
Objective: The purpose of this study was to compare the effects of superficial and deep insertion of acupuncture needles in the treatment of patients with neck-shoulder pain and to search for more effective acupuncture methods. Methods: The subjects were patients seen at the Meiji University of Integrative Medicine’s Department of Orthopedic Surgery Clinic. A randomized controlled clinical trial was conducted in which 20 patients with neck-shoulder pain were randomly allocated to either a superficial acupuncture group (n=10) or a deep acupuncture group (n=10). Treatment was applied to points where patients experienced the most pain. The maximum number of stimulation points for both groups was 10. In the superficial acupuncture group, the needle was only inserted to a depth of 5 millimeter. In the deep acupuncture group, the needle was inserted to a depth of 15 to 20 millimeter. Both groups were manually stimulated using a sparrow pecking method over 20 seconds, after which the needle was removed. Both groups were treated weekly for four weeks. The primary outcome measurement was intensity of pain evaluated using a Visual Analogue Scale (VAS). The secondary outcome measurement was the Neck Disability Index (NDI) for the purpose of evaluating the grade of disability in daily life due to neck-shoulder pain. Results: There were no significant differences in age, male-female ratio, disease duration, or the initial scores of VAS and NDI between the two groups. VAS and NDI scores indicated significant differences between the groups (VAS: <0.0001, NDI: p<0.0001) in change over time, with the deep acupuncture group having more favorable results than the superficial acupuncture group. The degree of change from the baseline at the time of each evaluation was calculated, and results for the two groups were compared. The deep acupuncture group showed significantly better improvement in the sustained effects after completion of treatment (VAS: p<0.05). There were no significant differences directly after the first treatment (VAS: p=0.72) or in cumulative effect after repeated treatment (VAS: p=0.24). Discussion and Conclusion: The results of this study suggested it would be more efficient to insert the needle to deep tissues when performing acupuncture treatment on subjective pain sites. The difference in the effects between the two acupuncture methods may be due to the difference in tissue stimulation received. The difference in effect is thought to be due to the differing influence of treatment on pain threshold, muscle blood flow, and muscle tones.

ABSTRACT
Kakkonkajutsubuto belongs to the Ephedra herb drug group and has useful properties for stiff shoulders, scapular neuralgia, and rheumatoid arthritis of the upper body. In this study, we assessed the effectiveness of kakkonkajutsubuto in patients with neck, shoulder, and upper-extremity pain from the viewpoint of decrease in a Visual Analog Scale (VAS) and adverse reactions. One hundred and twenty-four patients who had no gastrointestinal disorder, hot flashes, excessive sweating or other select symptoms were treated with kakkonkajutsubuto (5.0-7.5g/day). The VAS was used for the assessment of pain-relieving effect.Eighty-one patients improved dramatically (their pre/post administration VAS ratio was less than 50%), 21 improved (between 51 to 75%), and 22 did not improve (more than 76%). Eighty-two point three percent of patients improved in total. Five patients showed adverse reactions, such as general fatigue, stomachache, and edema, but these were not clinically significant. This study suggests that kakkonkajutsubuto can be used more widely for neck, shoulder, or upper-extremity pain.
