What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Spinopelvic mobility exerciseOther

    Participants will complete a 15-20 min session of therapeutic exercises performed by patients with assistance of a pre-recorded video. The exercise regimen has been developed by the investigators of this study to incorporate exercises to increase a patient's spinopelvic mobility. Study staff that has been properly trained will be present to guide the patient through the exercise regimen and ensure the exercises are being performed accurately.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Spinopelvic radiographic measurements

    Spinopelvic parameter measurements on pre- and post-exercise radiographs including pelvic incidence, pelvic tilt, sacral slope and lumbar lordosis. All measurements are angles calculated in degrees.

    Measured: Change from baseline to up to 1 hour after spinopelvic exercises same day.

  2. Lumbar mobility

    Calculated as the change in angle of lumbar lordosis between neutral standing and flexed-forward seated radiographs.

    Measured: Change from baseline to up to 1 hour after spinopelvic exercises same day

  3. Spinopelvic mobility

    Calculated as the change in angle of pelvic tilt between neutral standing and flexed-forward seated radiographs.

    Measured: Change from baseline to up to 1 hour after spinopelvic exercises same day

  4. Patient risk classification for THA instability

    Risk classification based on previously published risk factors for THA instability (lumbar stiffness, abnormal pelvic mobility, standing pelvic tilt greater than 13, sagittal spinal deformity)

    Measured: Change from baseline to up to 1 hour after spinopelvic exercises same day

Secondary outcomes (7)
  1. Oswestry Disability Index score

    Patient reported outcome for pre-existing back pain and disability. The questionnaire is comprised of 10 sections, where each section is scored on a scale from 0 to 5 and summed. Higher score totals indicates worse disability.

    Measured: Baseline

  2. Hip Society Score

    Patient reported outcome, scored from 0 to 100. Higher scores indicate better outcomes.

    Measured: Baseline

  3. Hip disability and Osteoarthritis Outcome Score for Joint Replacement (HOOS, JR)

    Patient reported outcome, scored from 0 to 100. Higher scores indicate better outcomes.

    Measured: Baseline

  4. The Veterans Rand 12-Item Health Survey scores (VR-12)

    Patient reported outcome. Scores are reported as a Z-score that is based on the United States population average of 50. Higher scores indicate better outcomes.

    Measured: Baseline

  5. Use of medication for hip/back pain

    Assessed by standard of care questionnaire prior to the pre-operative visit with provider for a total hip replacement.

    Measured: Baseline

  6. Severity of hip arthritis

    Graded using Kellgren-Lawrence scale for osteoarthritis on AP radiographs. Grades are between 0-4, where 0 indicates an absence of osteoarthritis and a 4 indicates severe osteoarthritis.

    Measured: Baseline

  7. Adverse events

    Any adverse events sustained from therapeutic exercises

    Measured: Day 1

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Spinopelvic radiographic measurements (time frame: Change from baseline to up to 1 hour after spinopelvic exercises same day.). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06838455, which also lists 10 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Nov 2026.
