Fig 1 Values for muscle strength of various muscle groups in subjects with late polio in percentage of values in healthy individuals in corresponding age group and sex. NOTE. Median and 5th, 25th, 75th, and 95th percentile values are given. Abbreviations: ext, extension; flex, flexion; L, left; R, right.
