This study aimed to investigate the gait modification strategies of trunk over
right stance phase in patients with right anterior cruciate ligament deficiency
(ACL-D). Thirty-six patients with right chronic ACL-D were recruited, as well as
36 controls. A 3D optical video motion capture system was used during gait and
stair ambulation. Kinematic variables of the trunk and kinematic and kinetic
variables of the knee were calculated. Patients with chronic right ACL-D
exhibited many significant abnormalities compared with controls. Trunk rotation
with right shoulder trailing over the right stance phase was lower in all five
motion patterns (P<0.05). Compared with controls, trunk posterior lean was higher
from descending stairs to walking when the knee sagittal plane moment ended
(P<0.01). Trunk lateral flexion to the left was higher when ascending stairs at
the start of right knee coronal plane moment (P=0.01), when descending stairs at
the maximal knee coronal plane moment (P<0.01), and when descending stairs at the
end of the knee coronal plane moment (P=0.03). Trunk rotation with right shoulder
forward was higher at the minimal knee transverse plane moment (P<0.01) and when
the knee transverse plane moment ended (P<0.01); during walking, trunk rotation
with right shoulder trailing was lower at other knee moments during other walking
patterns (all P<0.01). In conclusion, gait modification strategies of the trunk
were apparent in patients with ACL-D. These results provide new insights about
diagnosis and rehabilitation of chronic ACL-D (better use of walking and stair
tasks as part of a rehabilitation program).
