Brief Summary
The purpose of this study is to study the effects of core activation on knee joint loading during ambulation in patients with knee osteoarthritis (OA). This study aims to investigate the effects of transversus abdominis (TA) activation during simultaneous kinetic analysis of time to initial peak ground reaction force (T1) at the heel in the sagittal plane. The objective of this study is to determine whether patients with knee OA demonstrate changes in T1 during comfortable gait speeds when actively contracting the TA muscle. In addition, this study will serve as a pilot study in order to perform a post-hoc power analysis for future study on the effects of the independent variable (TA contraction/changes in core stability) on the dependent variable (T1). Null hypothesis: There will be no change in T1 in patients with knee OA during gait while contracting their TA. Alternate hypothesis: There will be a decrease in T1 in patients with knee OA during gait while contracting their TA.

During walking trials
Study Arms (1)
Without and With Transversus Abdominis
EXPERIMENTALWithout: Participants performed three trials of self-selected, comfortable paced walking in the motion lab to collect kinetic data, without transversus abdominis contraction. With: Participants performed three trials of self-selected, comfortable paced walking in the motion lab to collect kinetic data, with 50% MVIC transversus abdominis contraction.
Interventions
Participants were educated on how to contract their transversus abdominis (TA) muscle after having a surface EMG biofeedback device placed on their abdomen to provide audible biofeedback. Participants were asked to ambulate while maintaining TA contraction while ambulating at 50% of maximal volitional isometric contraction.
Eligibility Criteria
You may qualify if:
- those with medical diagnosis (providing written evidence from a physician, physician assistant, or nurse practitioner) of knee OA unilaterally or bilaterally.
You may not qualify if:
- bilateral total knee arthroplasty, requirement of an assistive device or assistance with ambulation, spinal diagnoses which contraindicate participation in spinal stabilization activities, and those currently limited by another lower extremity pathology at the time of participation.
