Sciatica is a debilitating and costly condition. Prognostically, patients presenting with leg pain often have a poor recovery and some go onto have spinal surgery. However, in the absence of nerve root compression on MRI, no surgical option is viable and patients are often discharged and encouraged to self manage. Neurodynamics offers a means to treat patients with non-compressive leg pain. To date, there is no research exploring which form of neurodynamic sliding technique offers the greatest therapeutic benefit in patients presenting with sciatica. The aim of this pilot study is to calculate how many patients would be needed to run a full scale trial evaluating therapeutic efficacy. Moreover, the pilot will assess the overall workability of the study and the feasibility of patient recruitment.
