Remember that backs are not amenable to a schedule award unless there is nerve injury effecting a leg or arm. The rating for the injury must be done using the methodology described in the July/August 2009 Guides newsletter. The July/August Guides newsletter is quite detailed. The essential criteria is a positive EMG finding. Note that I did not say an EKG or MRI. The Newsletter says EMG.
Even if there is a positive EMG, the award would probably not be adequate. If there was neck or low back surgery, the claimant stands a chance of financial recovery. If there is a foot drop, there is a better chance of financial recovery. If there is only a back strain, you should probably forget about an award. You will almost certainly be sent for a second or even third opinion.
Arguably unfair, but that is the current system.
