  • Bold value indicates significant difference.

  • Average difference (Δ=D−ND) of strength and manual dexterity (9-HPT) between the two sides is shown. Values indicate the mean and SD of all tested muscles.

  • *One missing value.

  • †Two missing values.

  • 9-HPT: 9-hole peg test; APB, abductor pollicis brevis; AT, anterior tibialis; D, dominant side; FDI, first dorsal interosseous; FS, foot strength (average between AT and TS); HS, hand strength (average between FDI and APB); N, number of tested patients; ND, non-dominant side; TS, triceps surae.
