Outcome measures
Primary outcome
Biomechanical measurements: angles and moments of force of joints of the lower
extremities and ground reaction forces. Main points of interests are:
-the differences in biomechanical outcome measurements between the test with no
interaction effect and the test with an interaction effect with virtual
reality.
-the difference in biomechanical outcome measurements between the patient and
control group per test.
Angles and moments of force of joints of the lower extremities and ground
reaction forces during heel strike, mid stance and pre-swing phases of the gait
cycle will be calculated. The angles and moments of force of joints of the
lower extremities and ground reaction forces during stair descending on the
force plate will be calculated.
Secondary outcome
Not applicable
Background summary
Patients with an ACL reconstruction have developed an adaptive locomotion
pattern after the traumatic injury of the ACL and the reconstruction surgery in
comparison with healthy individuals after one year. Nowadays perturbation
(balance and coordination exercises) rehabilitation programs on the CAREN
system are being developed for patients with an ACL reconstruction. The
expected results of a perturbation program using CAREN in patients with an ACL
reconstruction is a decrease in fear of movement, to facilitate a more normal
movement pattern during virtual reality activities, to facilitate patients in
activities to widen their cognitive limitations and to increase the stability
of the knee. The effect of virtual reality on the neuromechanics (control and
biomechanics) of the lower extremity during gait and stair descending in
patients with an ACL reconstruction has not been studied systematically, nor
published. The benefits of the study are to have more knowledge about the
adapting strategies of the patients with an ACL reconstruction in a virtual
environment, inhibit fixed motor programs so that patients start to function
better and to shorten rehabilitation programs. The test results of this study
could be used to improve the rehabilitation program of patients with an ACL
reconstruction.
Study objective
The aim of this study is to investigate the efficacy of virtual reality on gait
and stair descending in patients with an Anterior Cruciate Ligament
reconstruction.
Study design
observational study with open-label trial
Study burden and risks
The only potential risk factor for the subjects during the tests is falling.
This risk factor will be minimized for the subjects by wearing a safety harness
which will be attached on the safety frame. In the past no patients have
felled. Safety instructions of the CAREN system will be followed by the
investigators. The benefits of the study are to acquire more knowledge about
the adapting strategies of the patients with an ACL reconstruction in a virtual
environment, inhibit fixed motor programs so that patients start to function
better and to shorten rehabilitation programs. The test results of this study
could be used to improve the rehabilitation program of patients with an ACL
reconstruction.
