Table 2 Values of strength for elbow flexion/extension and wrist extension in C8-T1 and C7-T1 palsies.

From: Results and current approach for Brachial Plexus reconstruction

Type of palsy Elbow Flexion/Kg Elbow Extension/Kg Wrist Extension/Kg
C8-T1 16.2(95% CI, 13.5-18.9) 12.5 (95% CI, 7.9 17) 9.5(95% CI, 6.7-12.2)
C7-T1 11.6 (95% CI, 10.6-12.6) 3(95% CI,1.7-4.2) 6(95% CI, 3.6-8.3)
Normal 19(17.2-20.7) 11.8 (10.4-13.2) 13(95% CI, 11.4-14.5)
  1. Values of strength for elbow flexion/extension and wrist extension in C8-T1 and C7-T1 palsies. Strength in C7-T1 injuries was significantly (p < 0.05) reduced relative to the normal, contralateral limb. The rates for the C8-T1 injury group did not differ from normal values. In the C7-T1 group, elbow and wrist extension strengths were 25% and 46% those of the normal side, respectively.
