As has been previously discussed, neck and back injuries are some of the most common work related injuries in Texas. The Texas Division of Workers’ Compensation currently uses the 4th Ed. of the AMA Guides to Permanent Impairments. The DRE category V is the first level where the findings for the neck and back are substantially different. Neck: The patient has objectively demonstrated a significant upper-extremity impairment requiring the use of upper-extremity external functional or adaptive device(s). There may be total neurologic loss at a single level or severe, multilevel neurologic loss. A DRE category V to the cervical spine will yield a 35% whole body impairment rating. Back: Radiculopathy and loss of motion segment integity. Significant lower-extremety impairment is indicated by atrophy or loss of reflex(es), numbness with an anatomic basis, or electromyographic findings as in lumbosacral category III and loss of spine motion segment integrity as in lumbosacral category IV. If you have any questions about your impairment rating or workers compensation claim. Call the Texas Workers’ Compensation department at the Morris Law Firm (214)357-1782 or email at firstname.lastname@example.org.
