Core Activation and Stabilization for Knee OA
Osteoarthritis, Knee
About this trial
This is an interventional treatment trial for Osteoarthritis, Knee
Eligibility Criteria
Inclusion Criteria:
- English-speaking men and women
- 40 years old and older
- any race or ethnic group
- a documented diagnosis from a medical provider (i.e., physician, physician assistant, or nurse practitioner, etc.) of KOA, unilaterally or bilaterally.
- Previous or current physical therapy patients may be included (see exclusion criteria for exceptions).
Healthy controls will meet the same requirements, but:
- without a medical diagnosis of KOA
- have the ability to ambulate on a level surface without any report of pain in their knees at the time of gait assessment.
Exclusion Criteria:
- Those with other lower extremity injuries (orthopaedic, cardiovascular, neurologic, etc.) which are currently hindering their ability to ambulate
- those with current complaints of low back pain
- those who have undergone bilateral total knee arthroplasty
- those with concomitant diagnosis of rheumatoid arthritis
- those persons not able to ambulate independently with or without an assistive device
- those who have received a corticosteroid injection within the past two months
- those who have received a hyaluronic acid injection in the past six months
- those persons currently enrolled in a core training program as part of formal physical therapy or physical fitness.

Baseline Gait Comparisons of Groups
Gait with core activation
Knee OA Gait After core stabilization
Determine if kinetic (time to first peak ground reaction force [T1] and second peak ground reaction force [F2], both in the sagittal plane) and kinematic (peak stance knee flexion angle [KFA] and external knee adduction moment [KAM]) gait variables, and speed, differ between patients with KOA and age and gender matched controls during self-selected paced ambulation, and determine which ones have predictive relationships with Knee Injury and Osteoarthritis Outcome Score (KOOS) scores in the patients with KOA.
Determine if volitional core activation alters gait kinetics (T1 and F2), kinematics (KFA and KAM), and speed in patients with and without KOA during self-selected paced ambulation when compared to ambulating without volitional core activation, and whether the subjective pain complaints are significantly changed in the group with KOA. Determine whether there are baseline differences in core activation between those with and without KOA.
Determine if a six-week core stabilization program alters KOOS score, and the kinetics (T1 and F2), kinematics (KFA and KAM), and speed of gait in patients with KOA during self-selected paced ambulation as compared to their pre-intervention baselines. Determine if there is a predictive relationship between the number of completed intervention sessions performed and these observed changes.
