The X-ray reports L4 over L5 anterolisthesis with possible pars interarticularis defect (spondylolysis) and specifically recommends CT correlation. Traction may provoke symptoms or be inappropriate if there is an unstable slip or pars defect. It also has limited evidence of benefit for this condition.

First arrange spine/orthopedic review and the advised CT. MRI may also be needed if there is leg pain, numbness, weakness, or suspected nerve compression. Spondylolisthesis can cause L5 nerve-root impingement or stenotic symptoms, and progressive neurologic deficit requires prompt evaluation (Firestein & Kelley's Textbook of Rheumatology, p. 2606).

IFT: It is not a treatment for the slip itself, but it can be considered only as a short-term pain-relief adjunct after clinical screening, using comfortable sensory intensity and stopping if pain radiates/increases. Do not use it over areas with impaired sensation, skin lesions, a pacemaker/implanted electrical device, malignancy in the treatment area, or pregnancy over the lumbopelvic region. It should not delay diagnostic work-up.

A rehabilitation guideline for spondylolysis/listhesis similarly advises avoiding lumbar extension, loading, and impact early, with an exercise-centered program. A review of lumbar spondylolisthesis care describes traction and electro-physical agents only as limited adjuncts, not primary treatment.

Urgent referral today if she has new/progressive leg weakness, saddle numbness, urinary retention/incontinence, bowel-control change, fever, unexplained weight loss, or severe unremitting/night pain.

Also, the report notes an unexplained pelvic radiopacity. That should be clinically correlated by the referring doctor before proceeding with a routine modality-only plan.
