■拉伸改善了运动范围并改变了肌肉肌腱单元的粘弹性。我们假设有规律的伸展计划可以减少在超声心动图工作的员工疼痛的功能后果,超声,和介入实验室。这个探索性的,概念验证研究旨在告知对未来随机分组的期望,对照研究。
■在这个非盲区,非随机化,观察性研究,我们招募了196名在MayoClinic和MayoClinicHealthSystem的心脏病学和放射科的介入和超声心动图实验室工作的医疗保健专业人员,进行15分钟的颈部手术,上肢,低背,下肢伸展1年。疼痛的功能后果是通过使用手臂残疾自我报告的,肩膀,和手;颈部残疾指数;和罗兰-莫里斯问卷,在基线和1年时给药,以测量对拉伸的反应。进行了带有伤害评估计划的监测。怀孕的员工,不能做练习,或者在积极的骨科治疗中,被排除在外。
■在注册的196人中,68(35%)在基线和随访中提供了完整的数据。大多数参与者超过40岁(n=51;72%)和女性(n=51;72%)。参与者进行了120.5次拉伸(IQR,52-184)天。在整个研究期间,进行拉伸的天数分布良好,中位数为32个季度中的1、2、3和4(19-51),32(20-51)31(17-45)和32.5(12-47)天,分别。大多数参与者(52.3%)以前拉伸过,工作中拉伸18.9%,工作后拉伸28.8%。治疗组自我报告的上肢残疾得到改善,手臂残疾中位数显着降低,肩膀,和手得分(5.2至2.6;P=0.002)。颈部残疾指数评分绝对下降4%,在基线和1年随访之间(10%至6%,P=.017)。从基线到随访,罗兰-莫里斯问卷没有显著变化(1到0;P=.287)。没有参与者报告任何拉伸相关的伤害。
■常规拉伸程序可能代表有吸引力的,低成本,非侵入性选择,以减少在超声心动图工作的员工的上肢肌肉骨骼残疾,超声,和介入实验室。需要更大的随机试验来确认这种关联。
UNASSIGNED: Stretching improves range of motion and changes the viscoelastic properties of muscle-tendon units. We hypothesized that a regular stretching program would reduce the functional consequences of pain for employees working in echocardiographic, ultrasound, and interventional laboratories. This exploratory, proof-of-concept study was meant to inform expectations for future randomized, controlled studies.
UNASSIGNED: In this unblinded, nonrandomized, observational study, we enrolled 196 health care professionals working in the interventional and echocardiographic laboratories in the departments of cardiology and radiology at Mayo Clinic and Mayo Clinic Health System to perform 15-minute neck, upper extremity, low back, and lower extremity stretches for 1 year. The functional consequences of pain were self-reported by using the Disability of Arm, Shoulder, and Hand; Neck Disability Index; and Roland-Morris Questionnaire, which was administered at baseline and at 1 year to measure response to stretching. Monitoring with an assessment plan for injuries was undertaken. Employees who were pregnant, unable to do exercises, or under active orthopedic treatment, were excluded.
UNASSIGNED: Of the 196 enrolled, 68 (35%) provided complete data at both baseline and follow-up. The majority of participants were over 40 years (n = 51; 72%) and female (n = 51; 72%). Participants performed stretches for 120.5 (IQR, 52-184) days over the year. The number of days of doing the stretches was well distributed across the study period with median quarters 1, 2, 3, and 4 of 32 (19-51), 32 (20-51), 31 (17-45), and 32.5 (12-47) days, respectively. The majority of participants (52.3%) stretched before, 18.9% stretched during and 28.8% stretched after work. Self-reported upper extremity disability improved in the treatment group with a significant decrease in the median Disability of Arm, Shoulder, and Hand score (5.2 to 2.6; P = .002). There was an absolute 4% decrease in the Neck Disability Index score, between baseline and 1-year follow-up (10% to 6%, P = .017). There was not a significant change in the Roland-Morris Questionnaire from baseline to follow-up (1 to 0; P = .287). No participant reported any stretch-related injuries.
UNASSIGNED: A routine stretching program may represent an attractive, low-cost, noninvasive option to reduce upper extremity musculoskeletal disability of employees working in the echocardiographic, ultrasound, and interventional laboratories. Larger randomized trials are needed to confirm the association.
