Furthermore, results of the categorical and continuous primary and secondary outcomes from this pilot RCT will be used to calculate the sample size of an adequately powered RCT to determine which treatments currently used in the management of acute sciatica/lumbosacral radiculopathy of less than 4 weeks duration, is the most effective in reducing pain and disability in the short-term and prevent progression to persistent or recurrent sciatica/lumbosacral radiculopathy in the long term.
