Active or passive treatment for neck-shoulder pain in occupational health care? A randomized controlled trial.

ABSTRACT

AIMS: To compare the effectiveness of thoracic manipulations with instructions for physiotherapeutic exercises for the treatment of neck pain in occupational health care. METHODS: Seventy-five subjects aged 30-55 years from a random sample of 241 employees of the Finnish Broadcasting Company were randomly allocated to treatment in the form of four thoracic manipulations (n = 43), or instructions for physiotherapeutic exercises (n = 32). The subjects reported neck-shoulder pain on a structured pain questionnaire using a visual analogue scale (VAS, 0-10). Muscle tenderness and tender thoracic levels were evaluated by a blinded investigator (A.S.) at 6- and 12 month follow-ups. RESULTS: A statistically significant difference was found in self-reported worst pain by VAS at the 12 month follow-up in favour of the thoracic manipulation group. CONCLUSIONS: The natural course of the neck-shoulder pain in this study appears benign; pain was also reduced in the drop-out group. Both treatments were found effective at the 12 month follow-up. The effect of four manipulations was more favourable than the personal exercise program in treating the more intense phase of pain.
