OE Journal. 2013;1(12):115 BMC Musculoskelet Disord. 2010 May 27;11:991184 Computer workers from 7 Dutch organizations partook a health questionnaire were randomized to two groups, one receiving the feedback on their scores and a preventive advice and the other group continuing with the usual care. The effectiveness of the RSI QuickScan intervention program was found to be small and limited to a decrease in some risk factors exposures only, with no difference in the prevalence of symptoms or sick leave between the groups.
Was the allocation sequence adequately generated?
Was allocation adequately concealed?
Blinding Treatment Providers: Was knowledge of the allocated interventions adequately prevented?
Blinding Outcome Assessors: Was knowledge of the allocated interventions adequately prevented?
Blinding Patients: Was knowledge of the allocated interventions adequately prevented?
Was loss to follow-up (missing outcome data) infrequent?
Are reports of the study free of suggestion of selective outcome reporting?
Were outcomes objective, patient-important and assessed in a manner to limit bias (ie. duplicate assessors, Independent assessors)?
Was the sample size sufficiently large to assure a balance of prognosis and sufficiently large number of outcome events?
Was investigator expertise/experience with both treatment and control techniques likely the same (ie.were criteria for surgeon participation/expertise provided)?
Sí = 1
Incierto = 0,5

El Índice de Fragilidad es una herramienta que ayuda en la interpretación de hallazgos significativos, proporcionando una medida de fuerza para un resultado. El Índice de Fragilidad representa el número de eventos consecutivos que es necesario añadir a un resultado dicotómico para que el hallazgo deje de ser significativo. Un número pequeño representa un hallazgo más débil y un número grande un hallazgo más fuerte.
¿Por qué se necesitaba ahora este estudio?
In 15 European countries, 25% of the working population was found to have neck/shoulder and arm pain and were shown to have a 31% reduction in the quality of life score. Several preventive measures and exercise programs have been suggested along with frequent breaks. However, there is a lack of evidence regarding the effectiveness of a prevention program. This study specifically look into the efficacy of a preventive program and specific advice on reduction of repetitive strain injuries.
¿Cuál era la pregunta principal de la investigación?
For computer workers, is a questionnaire-based prevention program followed by preventive advice effective in reducing the prevalence of arm, shoulder and neck symptoms or Repetitive Strain Injury (RSI)?
- At 12 months follow-up, the intervention and usual care group were not significantly different in the reduction of the prevalence of arm, shoulder, and neck symptoms.
- The intervention group had a statistically significant improvement in terms of the scores, information, work posture and movement.
- The intervention and usual care group were not significantly different in changes in the number of sick leave days.
- Participants receiving the intervention were found to have increased awareness regarding prevention and hence were able to reduce exposure to adverse postures and movements (OR=0.478).
¿Qué es lo que más debo recordar?
The RSI QuickScan intervention program was not effective in reducing the prevalence of arm, shoulder, and neck symptoms. However, participants who received the intervention were certainly found to have increased awareness due to education regarding prevention and hence were able to reduce exposure to adverse postures and movements.
¿Cómo afectará esto al cuidado de mis pacientes?
A newly-developed intervention program in Netherlands has not proved to be significantly effective in reducing the prevalence of repetitive strain injury in computer workers.
