Are shoe insoles effective in the prevention and treatment of non-specific back pain?
Half of the trials were low quality studies with heterogeneous interventions and outcome measures, poor blinding and poor reporting. No long-term treatment and prevention data are available. The longest trial lasted 14 weeks.
Back pain is one of the commonest health problems in the industrialised world, with estimates that between 60-85% of the population will experience back pain at some point in their lives. Laboratory trials suggest that the use of shoe insoles might be beneficial in prevention and treatment of back pain, by absorbing the shock of the foot striking the ground and supporting the foot in proper alignment.
