4.4 Case Study:Low Back Pain
Background and Purpose：Low back pain（LBP）is a common complaint in the U.S.，and has many possible causes.Multiple physical therapy interventions，including electrotherapy，traction，and lumbar stabilization exercises such as bridging and planking variations，have been shown to be very effective in reducing LBP.The purpose of this case study is to examine the effects of lumbar stabilization exercise and electrotherapy on LBP.
Case Description：The patient was a 43-year-old male，who had been experiencing LBP for the past year.He reported falling off from a truck and landing with his hand tucked into his back.The patient was very limited in activities of daily living，and was reliant on pain medication to function day-to-day.Initial physical therapy examination showed significant limitations in trunk and hip strength and range of motion（ROM）.During the first few visits，the patient was unable to perform strengthening or ROM exercises effectively due to extreme levels of pain.Following application of H-wave，an electrotherapeutic modality，the patient was able to actively participate in therapy sessions，which included lumbar stabilization exercises.By the end of the patient’s therapy sessions，he demonstrated normal strength in the majority of hip/trunk muscles，as well as full ROM in all formerly tested motions.
Discussion：It is likely that the patient’s recovery was not due to H-wave application alone，but was multifactorial in nature.This case study has demonstrated that electrotherapy is an effective means of reducing pain for better participation in therapeutic exercise regardless of its impact on actual patient recovery.
