Lidocaine Injection Versus Sham Needling in Treating Whiplash Associated Disorder

Study Overview
=================
Brief Summary
-----------------
To determine the efficacy of lidocaine injection of trigger points versus subcutaneous injection in patients with subacute whiplash associated disorder following injury.

Detailed Description
-----------------
This is a double-blind, randomized controlled trial to determine the efficacy of lidocaine injection of trigger points versus subcutaneous injection in patients with subacute whiplash associated disorder following injury. Outcomes include pain, objective assessment, self-report function recovery, impact on work performance and globe perceived effects which will be assessed 5 minutes, 2 and 6 weeks following injection.
