324     Only employees with an objectively verifiable diagnosis qualify for a WPI rating under Table 9.13.2a: Specific nerve lesions affecting the upper extremities – sensory impairment and Table 9.13.2b: Specific nerve lesions affecting the upper extremities motor impairment. The diagnosis is made not only on credible and clinically logical symptoms but, more importantly, on the presence of positive clinical findings and loss of function. The diagnosis should be documented by electromyography as well as sensory and motor nerve conduction studies. As noted under the Principles of Assessment, the assessor should not order additional investigations solely for assessment purposes.
