A prospective trial of mechanical physiotherapy for lumbar disk prolapse.

Fifty consecutive patients with neuroradiologically confirmed lumbar disk prolapse, who responded to the first five daily physiotherapy sessions with pain centralization, were prospectively treated with mechanical physiotherapy (McKenzie). At a median follow-up of 55 weeks, there were high rates of patient satisfaction, recovery from neurological deficits, and employment, and a low rate of surgical interventions. Mechanical physiotherapy is thus a useful diagnostic tool and an effective treatment strategy for many patients with lumbar disk disease.
