 note = {Objective: We investigated whether transversus abdominis activity in patients with hip osteoarthritis（hip OA）changed after total hip arthroplasty（THA）. We also investigated the association between post-THA transversus abdominis activity and pain, muscle strength, and walking ability.
Methods: The study subjects, all female, included 24 healthy volunteers and 14 patients diagnosed with hip OA and admitted for unilateral primary THA. We compared the transversus abdominis contraction ratio of the healthy volunteers and the patients with hip OA before and after THA. We investigated the correlation between the transversus abdominis contraction ratio and pain, muscle strength, and walking ability.
Results: The transversus abdominis contraction ratio was significantly lower in patients with hip OA both pre and post-THA than in healthy volunteers. However, there was no significant difference between the pre and post-THA values. The post-THA transversus abdominis contraction ratio was significantly correlated with hip abductor strength on the operated side, knee extension strength on the non-operated side, and maximum walking speed.
Conclusions: In patients with hip OA, the activity of the transversus abdominis decreased after THA, and this decline in transversus abdominis activity was associated with reduced leg muscle strength and walking speed. We recommend assessing and treating the transversus abdominis.},
