摘要

Low back pain and injure are very common in all populations as well as among the nursing personnel. The prevalence of low back pain in nurses of Chang Kung Memorial Hospital of Taiwan was reported at 13.9%. The purpose of this study was to establish the handling capacity of nursing profession in prediction model through arthropometry and muscle strength, to keep the nursing management in employment screening, job design/ redesign and establishment of training programs.
Twenty-four young female nurses with age of 22.3±2.4 years old, body height of 157.2±4.6 cm and body weight of 51.7±5.5 kg, attended this study. The equipment used to obtain arthropometeric data was based on Kys Neo Martin's arthrometeric instrument set. The muscle strengths were measured in static (isometric) state by Veritle muscle power measurement and dynamic state by Ayoubs incremental weight lifter. The maximum acceptable patient handling capacities were checked by putting simulated task through a model plastic patient (different weight by changing pieces of lead inside the body, ranged from 35 to 62 kg), using the psychophysical approach. The height of bed for handling were set at 3 conditions, fixed height at 70 cm or 80 cm, and adjustable height to the greater trochanter of each nurse. The statistic methods including stepwise regression analysis, analysis of variance (ANOVA) and Duncans multiple range test were used.
For the prediction of maximum handling by statistical analysis, based upon the arthropometric data, the best predictors for maximum handling capacity were the acromial height, greater trochanter height and chest circumference. Based upon the static muscle strength, the combinations of static muscle strength (from arm, back. leg, shoulder) and the back muscle strength were two best indicators. Base upon the dynamic muscle strength the 6 foot incremental lifting and knuckle height lifting scores were the two best predictors. In either circumstance, the addition of body weight, that yielded the estimated data were accurate for prediction in all scales..
The maximum acceptable patient handling capacities were found to vary with the bed height, in sequence as 49.8±7.9 kg when the bed was set to the femoral trochanter height of the nurses (90.1±3.9 cm), 47.6±8.1 kg at 80 cm bed height, and 43.1±7.6 kg at 70 cm bed height. There was no significant difference in handling capacities between the bed at 80 cm height and up to the femoral trochanter of the nurse, but significantly lower at 70 cm bed height (p＜0.05). The applications of ergonomics and arthropometry to the nursing profession in the hospital should not be neglected.
