Data entry workers perceptions and satisfaction response to the "stop and stretch" software program.
ABSTRACT Cumulative Trauma Disorder (CTD) is a collection of chronic musculoskeletal disorders caused by frequent, sustained, and repetitive movements, most notably by computer usage at the workplace. A computer based break reminder program (Stop and Stretch) has been developed and installed to prevent CTDs caused by prolonged computer usage at the workplace. We investigated users' opinions to the Stop and Stretch program at their work place. 19 computer users were recruited as the subjects of the study. We conducted a survey after all the subjects used the Stop and Stretch program for one month. Among the nineteen subjects, 52.5% or 10 noticed a difference of symptoms after using the program; 63.3% or 12 thought the program had positive effect on their productivity; 100% or all 19 thought the program was easy to follow; 100% or all 19 thought it was helpful; 94.7% or18 were satisfied with the program; and the same value would recommend the program to others. When grouped into those who had prior experience with using stretch and exercise as part of their work routine15 subjects had no prior experience; and 14 participants within that group were satisfied or very satisfied with the program; 93.3% or 14 would recommend it to co-workers; and over half of those 15 thought the program is easy to use. The study provided insight to the response to using "stretch break software" and provided indicators of satisfaction with the Stop and Stretch program and that the program had sufficient usability and acceptance within a workplace setting which might be applied in other work settings similar to these.

ABSTRACT: This article reviewed the literature to clarify the physiological effects and benefits of, and misconceptions about, stretches used to reduce musculoskeletal disorders. Nine databases were reviewed to identify studies exploring the effectiveness of stretching to prevent work-related musculoskeletal disorders. Included studies were reviewed and their methodological quality was assessed using the PEDro scale. The physiological effects of stretches may contribute to reducing discomfort and pain. However, if other measures are not in place to remediate their causes, stretches may suppress awareness of risks, resulting in more debilitating injuries. If inadequately performed, stretches may also cause or aggravate injuries. Careful analysis and stretching program design are required before implementing stretches. Seven studies evaluating the effectiveness of stretching to prevent musculoskeletal disorders in different occupations were identified and reviewed. The studies provided mixed findings, but demonstrated some beneficial effect of stretching in preventing work-related musculoskeletal disorders. However, due to the relatively low methodological quality of the studies available in the literature, future studies are necessary for a definite response. Future studies should minimize threats to internal and external validity, have control groups, use appropriate follow-up periods, and present a more detailed description of the interventions and worker population.Journal of Rehabilitation Medicine 06/2008; 40(5):321-8. · 2.13 Impact Factor

ABSTRACT: The objective of this descriptive case study was to analyze the interference of clothing with exercise performance, joint range of motion (ROM), and comfort during a session of labor gymnastics wearing a uniform (UNI) and specific exercise clothes (SEC). Twenty female workers (28.9±10.2 years) from a company in Florianópolis were studied. A photo camera, Wells bench, a questionnaire, and interview were used for data collection. The subjects were submitted to seven types of exercise wearing UNI and SEC: hip flexion, shoulder flexion, trunk flexion-hips and ankle angles, shoulder extension, modified trunk flexion-hips and ankle angles, horizontal shoulder adduction, and a sit-and-reach test. The results were analyzed using the paired t-test, chi-square test, and Fisher’s exact test (p≤0.05). Seven women wearing UNI tended not to show the body, 17 removed some part of UNI, and 13 noted movement limitation. Discomfort was lower in the upper body part during hip flexion and horizontal shoulder adduction and in the lower part during shoulder flexion, extension and horizontal shoulder adduction. Lower ROM values were observed for subjects wearing UNI compared to those wearing SEC during hip flexion (p=0.017), shoulder flexion (p=0.0075), trunk flexion (hips and ankle angles), modified trunk flexion (ankle angles), and the sit-and-reach test (linear and angular values) (p<0.001). Trunk flexion performance (ankle angles) was better in the UNI condition (p=0.001), probably because the subjects were wearing shoes. In conclusion, clothing tends to interfere with ROM and comfort, but not with exercise performance.Revista Brasileira de Cineantropometria e Desempenho Humano. 01/2010;

ABSTRACT: To select a questionnaire and walking capacity test based on comparison of clinimetric properties and mutual association to be used as "core" qualifiers for physical functioning in patients with late-onset sequelae of poliomyelitis. Repeated-measures at 3-week intervals. An unselected sample of 57 patients with late-onset sequelae of poliomyelitis from a prospective cohort study. Physical functioning scales from Short Form-36 (SF36-PF), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC-PF) and Nottingham Health Profile (NHP-PM). Timed-Up-and-Go test, 10-m walking at self-preferred and maximum speed, and 2-min walk test. Test-retest reliability of SF36-PF and WOMAC-PF was good (intraclass correlation coefficient (ICC) 0.92 and 0.89, respectively), sufficient for NHP-PM (ICC 0.74) and excellent for walking tests (ICC 0.93-0.96). The smallest detectable changes were 18.4 and 16.5, respectively, for WOMAC-PF and SF36-PF, and 26.7 for NHP-PM. The smallest detectable change was best for the 2-min walk test (22.9 m). Correlation coefficients between questionnaires and walking tests ranged from 0.32 to 0.69, with the highest correlation between the SF36-PF and 2-min walk test. The SF36-PF and 2-min walk test are recommended as core qualifiers for physical functioning, the major increasing disability in late-onset sequelae of poliomyelitis, to assess perceived physical performance and walking capacity in research and clinical practice.Journal of Rehabilitation Medicine 06/2008; 40(5):387-94. · 2.13 Impact Factor
