Studies should investigate whether thrust mobilization/manipulation generates a different clinical outcome than nonthrust mobilization/manipulation techniques for hip OA, and whether specific joint testing is necessary to guide mobilizations, or if general application of mobilization/manipulation to the hip will provide benefits in pain and disability for patients with hip OA. Future studies should also inquire into the usage of medications following MPT interventions for hip OA and identify the duration of long-term benefit following MPT for hip OA.
