Study information

Primary study design	Interventional
Study design	Randomised, cluster balanced, intervention trial
Secondary study design	Randomised controlled trial
Scientific title
Study acronym	SPA (Sundhedsfremme På Arbejdspladsen; Specific Physical Activity at the work site)
Study objectives	1. Physical activity training at the work site will reduce musculoskeletal complaints in the neck and shoulder region among office workers and reduce absenteeism 2. Specific resistance training of the neck/shoulder region is superior to all-round physical exercise for reducing neck/shoulder complaints 3. Pattern of musculoskeletal disorders as well as physical activity level at baseline modify the training effect
Ethics approval(s)	Approval received from the local ethics committee (De Videnskabsetiske Komiteér for Københavns of Fredriksberg Kommuner) on the 12th July 2004 (ref: KF 01-201/04).
Health condition(s) or problem(s) studied	Work-related neck/shoulder disorders
Intervention	Participants are randomised to receive one of the following: 1. Specific resistance training for the neck/shoulder region 2. All-round physical exercises 3. Information on health promotion as a control group All groups were allowed to use one hour per week during work time for one year. Group one was scheduled most regular with 20 minutes three times per week. Group two was motivated to perform physical activity two to three times per week.

Key secondary outcome measure(s)	1. Muscle strength 2. Fitness (aerobic capacity) 3. Body Mass Index (BMI) 4. Salivary cortisol as stress marker These measures were taken examiner-blinded at baseline, after four to five months and again after 12 months of intervention.
