Motor unit number estimation was employed to assess muscle innervation in 76 patients with prior poliomyelitis. Of the 68 patients who were < 70 years of age, new musculoskeletal symptoms had appeared in all but four; the mean latent interval was 38.0 +/- 10.1 years. As expected, there was a high incidence of muscles exhibiting denervation in previously affected limbs (87%). However, the incidence in supposedly unaffected limbs was also high (65%). Significant differences in the degree of… CONTINUE READING
