i have a 51 year old patients who was diagnosed to have a spondylolysis on L4L5. Patients experienced pain upon prolong standing and walking. experienced pain during the night. pain releived thru stooping forward. Rx includes TENS + HMP on paralumbar area for 20 mins, US @ 2.0 w/cm2 for 5 mins at paralumbar area. William flexion exercises. After 2 weeks of daily PT treatment, there was no progress. the pain still feel the burning sensation on the lower extremeties. I would welcome any suggestions that would help my patient at least eliminate the pain or is there a chance for them to achieve their functional capability? How many weeks or months of tx in order to see progress or results?
