Study hypothesis
Our hypothesis is that employees whose work time is temporarily reduced and work load adjusted during early stage of disability will have less disability days and faster return to regular work duties than employees on conventional sick leave.
Ethics approval
Approved by the Coordinating Ethics Committee of Hospital District of Helsinki and Uusimaa on 20 December 2005 (HUS 461/E0/05). Amendment was approved on 24 October 2006.

Condition
Musculoskeletal disorders
Intervention
Intervention: Part-time sick leave (daily work load reduced by restricting work time by about 50%, and, if necessary, remaining work tasks modified so that working should be possible despite the symptoms)
Control: Full-time sick leave

Primary outcome measures
1. Number of days from the initial visit to the return to regular work activities
2. Total number of part- and full-time sick leave days during one- and two-year follow-up
Secondary outcome measures
1. Pain, measured using numerical scale 0 to 10 (0 = no pain, 10 = unbearable pain) at 0, 1, 3, 8, 12 and 52 weeks
2. Self-assessed function (Oswestry back questionnaire; shortened Disabilities of the Arm, Shoulder and Hand questionnaire [Quick DASH]; Comprehensive OsteoArthritis Test [COAT]) at 0, 1, 3, 8, 12 and 52 weeks
Costs and benefits to the employee, employer and society will be estimated in both study groups.

Eligibility
Participant inclusion criteria
Employees who seek medical advice in the occupational health service primarily due to musculoskeletal pain in the neck or shoulder region, back or upper or lower extremities, are eligible to the study. The symptoms and related disability must warrant prescription of full-time sick leave according to the current practice, but the physician considers the employee to be able to work part-time without the risk of the health condition to deteriorate.
Specific inclusion criteria:
1. 18 to 60 years of age
2. Permanent or long-term employment (30 hours or more per week)
3. No sick leave or other absence exceeding two weeks during the preceding month
4. Not more than 30 days on sick leave due to any health problem during three preceding months
5. Employee is not listed for any surgery that requires more than one week of sickness absence
6. No plan for longer absence from work during 12 months after enrollment
7. An employee can be enrolled only once
