Scientific titleThe efficacy of correction of leg length discrepancy on low back pain among meat industry workers
Study hypothesisLeg length discrepancy may be related to low back pain in occupations with prolonged walking and/or standing.
Ethics approval(s)The Ethics Committee of South Ostrobothnia Central Hospital, 20/12/2006
ConditionLow back pain
InterventionUltrasound is used to measure both legs of the participants and the leg length discrepancy (LLD) 5mm or more. We also ask if the participants have low back pain (LBP) scale 1-10. Then we randomise them in two groups.

In the intervention group the participants are given soles which correct 70% of LLD. In the control group the participants are given soles without correction. We ask questions (Oswestry, Roland -Morris, RAND, pain scales) at the beginning of the study and after 3, 6 and 12 months
Intervention typeOther
Primary outcome measureIntensity of low back pain (10 cm-VAS), measured at the beginning of the study and after 3, 6 and 12 months
Secondary outcome measures1. Oswestry Disability
2. Roland-Morris Disability
3. RAND-36 Quality of Life
Measured at at the beginning of the study and after 3, 6 and 12 months
