The purpose of this study is to examine the extent to which spinopelvic exercises may affect either sagittal spinal deformity or spinopelvic mobility and identifying patients at risk for hip instability following a total hip replacement.

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.
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.
Time frame: Change from baseline to up to 1 hour after spinopelvic exercises same day.
Lumbar mobility
Calculated as the change in angle of lumbar lordosis between neutral standing and flexed-forward seated radiographs.
Time frame: Change from baseline to up to 1 hour after spinopelvic exercises same day
Spinopelvic mobility
Calculated as the change in angle of pelvic tilt between neutral standing and flexed-forward seated radiographs.
Time frame: Change from baseline to up to 1 hour after spinopelvic exercises same day
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)
Time frame: Change from baseline to up to 1 hour after spinopelvic exercises same day
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.
Time frame: Baseline
Hip Society Score
Patient reported outcome, scored from 0 to 100. Higher scores indicate better outcomes.
Time frame: Baseline

Hip disability and Osteoarthritis Outcome Score for Joint Replacement (HOOS, JR)
Patient reported outcome, scored from 0 to 100. Higher scores indicate better outcomes.
Time frame: Baseline
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.
Time frame: Baseline
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.
Time frame: Baseline
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.
Time frame: Baseline
Adverse events
Any adverse events sustained from therapeutic exercises
Time frame: Day 1
