Kinematic Analysis of Healthy Hips during Weight-Bearing Activities by 3D-to-2D Model-to-Image Registration Technique

Table 2

The hip flexion/extension [flexion +, extension −] and adduction/abduction [adduction +, abduction −] angles at the maximum hip internal and external rotations [internal +, external −] during twisting.

Twisting	Hip flexion/extension (°)	Hip adduction/abduction (°)	Maximum hip internal and external rotations (°)
Contralateral	0.5 ± 5.7	−0.9 ± 3.5	−30.7 ± 17.3
Ipsilateral	18.0 ± 13.7	−6.4 ± 4.9	29.2 ± 13.5

Values are expressed as mean ± SD.
