Table 2 Time of injury within-image spatial frequency analysis parameter measures of injured and contralateral limbs

From: Spatial frequency analysis detects altered tissue organization following hamstring strain injury at time of injury but not return to sport

SFA parameter Imaged limb Within-image region Parameter value P-value
[95% Confidence Interval]
PSFR (mm−1) Involved Injury site 0.77 (0.24) p = 0.06

Adjacent 0.89 (0.25)
Contralateral Mirrored injury site 0.83 (0.18) p = 0.16
[− 0.04, 0.22]
Adjacent 0.92 (0.26)
Mmax% (%) Involved Injury site 1.41 (0.43) p < 0.01
[0.51, 1.21]
Adjacent 2.28 (0.50)
Contralateral Mirrored injury site 2.49 (0.58) p = 0.30
[− 0.49, 0.17]
Adjacent 2.33 (0.67)
