Question:
Are postural exercises delivered by Mensendieck/Cesar therapists more effective in decreasing pain, reducing disability and improving health-related quality of life in visual display unit workers with early non-specific work-related upper limb disorders than strength and fitness exercises delivered by physiotherapists?
Design:
Randomised trial with concealed allocation and intention-to-treat analysis.
Participants:
Eighty-eight (6 drop-outs) visual display unit workers with early non-specific work-related upper limb disorders.
Intervention:
One group received 10 weeks of postural exercises while the other group received 10 weeks of strength and fitness exercises.
Outcome Measures:
Pain was measured with a 10-cm visual analogue scale, disability was measured with the Disabilities of Arm, Shoulder and Hand questionnaire, and health-related quality of life was measured with the Short Form-36. Number of participants experiencing upper limb complaints was also collected. Outcome measures were collected at baseline and again at 3, 6, and 12 months.
Results:
There was no significant difference in decrease in pain between the groups at 3 months (0.6 cm, 95% CI 0.0 to 1.2), 6 months (0.2, 95% CI -0.3 to 0.7), or at 12 months (0.1, 95% CI -0.6 to 0.8). Differences between the groups in upper limb complaints, disability, and health related quality of life were also small and not significant at any measurement occasion.
Conclusion:
Postural exercises did not result in a better outcome than strength and fitness exercises. However, 55% of visual display unit workers with early non-specific work-related upper limb disorders reported being free of complaints one year after both interventions were commenced.
