Upper limb musculoskeletal complaints among technicians working in a diagnostic tuberculosis laboratory: two case reports.

Upper limb musculoskeletal complaints are common among certain health professionals. We report two cases, both involving technicians working in a diagnostic tuberculosis laboratory in Hong Kong. A work process evaluation suggest that the need to repeatedly open and close small bottles, as well as to work for prolonged periods of time in confined areas, could be related to the workers' clinical presentation. The cases are also compatible with the diagnosis of repetitive strain injury (RSI) of the upper limb, but this term is not commonly used nowadays because of various definitional issues. A review of the various diagnostic issues in RSI is presented.

Time off work in hand injury patients.

PURPOSE: To evaluate the average time off work for patients with hand injuries as well as factors influencing the length of time off work for subjects who had returned to work. METHODS: A total of 124 subjects were recruited and followed up 2 weeks after being discharged from therapy or until they resumed work. Factors affecting the time off work such as the severity of injury, number of operations, educational level, physical job demand, and presence of compensation claims, complications, and posttraumatic stress were also examined by multiple regression. The relationship between the severity of injury, time off work, and length of rehabilitation time was also examined. RESULTS: In 124 subjects, 109 resumed their previous jobs, with an average of 8 weeks off work and 9 weeks in regular rehabilitation. The result shows that the severity of injury, number of operations, and presence of compensation claims were the predictors for the length of time off work in hand injury patients. In addition, the time off work and length of rehabilitation time increased with more severe injury. However, a cross-over was noted in the severe grade of severity of injury; that is, the time off work was shorter than the length of rehabilitation time for those with a less severe level of injury (minor to moderate level) and vice versa for those with major severity of injury. CONCLUSIONS: To a certain extent, the result enhances our understanding of prolonged time off work after hand injury and may help to optimize rehabilitation after injury. For those who are in the high-risk group with factors that are not under control, early planning and retraining should be given to avoid prolonged time off work.

The use of Disabilities of the Arm, Shoulder, and Hand Questionnaire in rehabilitation after acute traumatic hand injuries.

This longitudinal observational prospective study evaluates the use of a self-reported measure Disabilities of the Arm, Shoulder, and Hand (DASH) in assessing traumatic hand injury patients. A total of 146 subjects were invited to fill out a validated questionnaire (DASH) during their first consultation and at discharge from therapy. The findings revealed a significant improvement in DASH scores upon discharge from therapy. The use of Quick DASH, an 11-question shortened version of the full 30-question DASH, also generated similar results with the psychometric properties maintained. Despite the low correlation between DASH and the therapists' measures of recovery of power grip, the results of this study confirmed the effectiveness of using the DASH in assessing traumatic hand injury patients. Clinical implications suggest that the DASH can be used to assess the improvement in the functional status of traumatic hand injury subjects, as well as to enhance therapists' understanding of the subjects' perspective regarding their disability, and to assist in effective treatment planning. Further study on the application of the Quick DASH in larger population, and its association with functional status is suggested.
