Comparison of PPT values between sides for the Achilles tendinopathy group (n = 14), excluding bilateral cases (n = 3).
| Achilles Tendinopathy Group INVOLVED Side† | Achilles Tendinopathy Group NON-INVOLVED Side† | Mean Difference Between Sides† | Within group comparison (t-test) | |
|---|---|---|---|---|
| Achilles Mean PPT (kg/cm2) | 6.47 ± 3.06 (4.87, 8.07 ) | 10.45 ± 3.81 (8.45, 12.45) | 3.98 ± 1.31 (1.30, 6.66) | t(26) = -3.040, p = 0.005 |
| Anterior Tibialis Mean PPT (kg/cm2) | 7.93 ± 4.64 (5.50, 10.36) | 7.68 ± 2.79 (6.22, 9.14) | -0.25 ± 1.45 (-3.22, 2.72) | t(26) = .168, p = .868 |
| Thenar Eminence Mean PPT (kg/cm2) | 5.20 ± 2.17 (4.06, 6.34) | 5.67 ± 2.11 (4.56, 6.78) | 0.47 ± 0.81 (-1.19, 2.13) | t(26) = -.590, p = .560 |
CI = confidence interval; kg/cm2 = kilograms per centimeter squared; PPT = pressure pain threshold
