简要总结
After spinal fusion and decompression surgery there is a possible risk of developing chronic back pain. After surgery there is typically inflammation around the operation site and this inflammation can be painful and debilitating to patients.
Many possible treatment plans have been incorporated to assist the patient with recovery - notably medications, physical therapy, and braces. However, few studies have looked at laser diodes that utilize high-power laser lights that are aimed at decreasing pain and inflammation. Investigators aim to look compare patients using a back brace with laser diodes within versus those who wear a normal brace used as a placebo. Investigators will also assess the patient's surgical wound to monitor the progression of wound healing while using the brace.
详细描述
This study will review charts of 80 patients who have experienced chronic back pain at various operative sites of a teaching medical institution, including the inpatient academic medical center, outpatient ambulatory hospital, and regional trauma center. Deidentified demographic data that will be collected via extensive chart reviews include age, sex, BMI, preoperative diagnosis, pre- and post-operative pain scales, motor exams, and function questionnaires. Operative data will include operative time and estimated blood loss (EBL). Patients that have already expressed interest in receiving spinal fusion or decompression surgery will come into clinic for consultation and enrollment in the study. Regardless of study participation, patients will receive either surgery. For the study, 80 subjects will be enrolled (40 with minimally invasive spinal fusion and 40 with minimally invasive decompression surgeries). Prior to the surgery date, subjects will complete pre-operation questionnaires that include the Visual Analogue Scale (VAS) and the Oswestry-Low-Back-Pain-Disability Index (ODI) to self-evaluate their current pain level and ability to perform basic lifestyle functions, respectively. Following surgery, enrolled subjects will then receive a brace that contains laser diodes or a sham (placebo) brace that appears identical to the diode-containing brace but lacks functional diodes. Subjects will wear the brace 3 times/day for 12 minutes each session for 12 weeks. They will complete and submit via the REDCap electronic submission portal the VAS and ODI questionnaires at the following time points after surgery: 2, 4, 6, 8, and 12 weeks. Subjects will also submit photos of their surgical scars for evaluation by the research study team members. Scar and wound healing will be assessed using image analysis software (Image J) according to the Stony Brook Scar Evaluation scale. Photos will be stored on a safe and secure encrypted server.

研究组 & 干预措施
Brace With Electrical Diodes
The patient will be given a laser diode brace to wear for 1 year. At the defined time points following surgery (2, 4, 6, 8, and 12 weeks), subjects will be asked to complete pain and ability-to-function questionnaires and submit scar/wound images to determine their status at each time interval.
干预措施: Laser Diode Brace
Sham Brace Without Electrical Diodes
The patient will be given a sham/placebo laser diode brace to wear for 1 year. At the defined time points following surgery (2, 4, 6, 8, and 12 weeks), subjects will be asked to complete pain and ability-to-function questionnaires and submit scar/wound images to determine their status at each time interval.
干预措施: Sham Laser Diode Brace
结局指标
主要结局
Self-reported patient outcome questionnaires after photobiomodulation therapy - VAS
时间窗: 3 months
Subjects will fill out two questionnaires related to their pain and quality of life before and after surgery with laser diode brace photobiomodulation therapy. The first survey is the Visual Analog Scale (VAS), which asks subjects to state how good or bad their current health state is on a scale of 0-100, 1 being the worst imaginable health state and 100 being the best imaginable health state. There are two additional questions that ask subjects to provide a rate their current back and leg pain on a scale of 0-10, with 0 being no pain and 10 being worst imaginable pain.
Self-reported patient outcome questionnaires after photobiomodulation therapy - ODI
时间窗: 3 months
The second survey is the Oswestry Disability Index (ODI), which is designed to provide information on how the subject's pain is affecting their everyday life. There are 10 sections on the survey each graded on a scale from 0-5 with 5 being the most impaired. The total score scales from 0-50, where 0-10 denotes minimal disability and 40-50 denotes that the pain impinges on all aspects of their daily lives.
