Postural control in nurses with and without low back pain.

BACKGROUND: Low back pain (LBP) is common in nurses, but it is unclear if the pain is associated with measurements of postural control. Objective measurements of function might be useful in the evaluation of patients with LBP in order to evaluate and predict disability, and in the study of the pathophysiology of chronic LBP. METHODS: In a cross-sectional study, we measured the number of postural adjustments, and degree of posterior-lateral sway in 81 nurses, using a computerized postural sway four-platter measurement system. RESULTS: There were 41 (56.6%) nurses who complained of LBP at the time of testing, and another 12 (14.8%) with a past history of LBP. Nurses with LBP consistently used more postural adjustments to keep their balance (p<0.003), and in some positions postural adjustments were positively associated with the degree of past and present pain. LBP was not significantly associated with the degree of lateral sway. CONCLUSIONS: Nurses either with present or a past history of LBP use an increased number of postural adjustments to maintain balance. Studies are warranted to determine if postural testing can predict the development of LBP or aid in determining appropriate preventive measures.

The implementation of motor learning principles in designing prevention programs at work.

Occupational therapy practitioners offer services to workers in the workplace to prevent musculoskeletal disorders (MSDs), to help the injured worker restore function, and to recover capacities needed to return to the job. Despite the existence of some evidence about the efficacy of prevention programs, there is uncertainty and even disagreement among health professionals, about the outcome of prevention programs for people with MSDs. It is proposed that principles of motor learning can assist the therapist in structuring prevention programs to facilitate the workers learning of correct movement patterns. This paper discusses basic concepts of motor learning emphasizing characteristics of the learner, the type of task, the structure of practice and application to prevention programs at work settings. We present a four-stage model for prevention programs based on principles of both motor learning and ergonomics. This model coincides with the broad perspective suggested in current occupational therapy models which focuses on the person, the environment, the occupation and their effects on occupational performance.

Developmental evaluation of children born to mothers occupationally exposed to waste anesthetic gases.

BACKGROUND: The etiology of developmental delay in children is frequently unknown. Increasing evidence supports the possibility that environmental and occupational factors might be part of the basis for such delays. This study focuses on the development of children born to mothers who were exposed during their pregnancy to waste anesthetic gases. METHODS: The study population included 40 children aged 5-13 years born to female anesthesiologists and nurses working in operating rooms (OpRs) exposed to waste anesthetic gases, and 40 unexposed children born to female nurses and physicians who worked in hospitals during their pregnancy but did not work in OpRs. The unexposed group was matched for children's age and gender and maternal occupation (nurses vs. doctors). By means of standardized developmental tests, the present study population was evaluated for their medical and neurodevelopmental state. Questionnaires were given for the detection of attention and activity levels as perceived by the parents. Additional questionnaires dealt with information concerning developmental milestones, maternal and fetal morbidity, and gynecological history. RESULTS: No differences were noted between the groups as newborns or in developmental milestones at the age of 5-13 years; however, the mean score of gross motor ability was significantly lower in the exposed versus the unexposed group. Additionally, the mean score of the DSM-III-R Parent-Teacher Questionnaire (PTQ) (i.e., measure of inattention/hyperactivity) was higher in the exposed group. The level of exposure, as measured by the number of weekly hours in the OpRs, was significantly and negatively correlated with fine motor ability and the score of IQ performance. CONCLUSIONS: Our study supports the hypothesis that occupational exposure to anesthetic gases might be a risk factor for minor neurological deficits of children born to mothers who work in OpRs and therefore indicates the need for more studies in this area and perhaps more caution among OpR pregnant women and employers.

Functional capacity evaluations as a post-offer employment: a case study.

Functional capacity evaluations in the post-offer phase of employment has the capacity to minimize work related injuries and promote wellness on the worksite. This paper includes a discussion of the value of post-offer evaluations and possible assessment options. To investigate the feasibility of administering post-offer evaluations, a case study was initiated. The Physical Work Performance Evaluation (PWPE) was administered to a new employee, VA, who was employed for the task of kneading dough, at a major food company. When compared to detailed work demands, there was no match between the job demands, and the client's capability in two sub-tests: lift from waist to eye level and trunk rotation. Based upon findings, recommendations for an initial graded work schedule, basic strengthening exercises, and modifications of the job site and task were made to the employer. The project was initiated with the hope of raising employee's and employer's awareness of workers health issues in the post-offer phase as it express itself in post-offer evaluation that aims to prevent musculoskeletal problems. This article aims to expand occupational therapists' awareness to the potential benefits of such a process.
