| Scientific title | The Computer Automated Pause Software (CAPS) study: randomised controlled trial in the effectiveness of pause software in VDU workers for prevention of work related upper extremity complaints |
| Study acronym | CAPS study |
| Study objectives | Complaints of arm, neck, shoulders, non-specific pain of the upper extremities, repetitive strain injury (RSI). The aim of this study is twofold: on the one hand to investigate whether use of break software reduces risk factors in VDU work and on the other hand whether RSI complaints are prevented and reduced. Research questions: 1. Does the use of break software lead to a reduction of RSI risk factors in VDU workers, compared to not using break software? 2. Does efficient use of break software lead to prevention of RSI complaints in VDU workers compared to VDU workers that do not have break software to their disposal? 3. Does efficient use of break software lead to a reduction of existing RSI complaints in VDU workers compared to VDU workers that do not have break software to their disposal? |
| Ethics approval(s) | Not provided at time of registration |
| Health condition(s) or problem(s) studied | Repetitive strain injury (RSI) |
| Intervention | The intervention group will have break software at their disposal in an active way: they will know how to set up and use the software and will have background information on the possible benefits of the break software. The control group will not have break software at their disposal. |
| Intervention type | Other |
| Primary outcome measure | 1. Main outcomes are prevalence and incidence of RSI risk factors and complaints. A worker will be defined as an RSI case if symptoms are present on at least 4 days during at least 1 week in the last 12 months. Symptoms have to be present in one or more of the upper extremity body regions: neck, upper back, shoulder, elbow, forearm, wrist and/or hand (SALTSA definition). 2. Duration of computer use will be registered with WorkPace registration software 3. Complaints will be measured with the QuickDASH questionnaire. Pain and complaints in the previous 24 hours will be measured with a Visual Analogue Scale. The average pain intensity will be evaluated by the worker on an 11-point numerical scale ranging from 0 (no pain) to 10 (as much as can be imagined). |
| Secondary outcome measures | 1. Data on costs will be gathered from several sources 2. Data on sick leave will be gathered from the company's registration 3. Direct costs (visits to the general practitioner etc.) due to upper limb musculoskeletal disorders will be gathered by questionnaire 4. Data on productivity will be collected by registering the amount of processed claims |
