简要总结
The literature has shown evidence of the effectiveness of prehabilitation programs on post-operative recovery for musculoskeletal conditions; however, evidence for prehabilitation for lumbar spinal stenosis (LSS) is limited. Investigators have found that there is very low to low quality evidence for the effect of prehabilitation interventions for improving outcomes following lumbar spine surgery. Therefore, the purpose of this study will be to determine the feasibility of a prehabilitation program for patients undergoing LSS surgery, and pilot test the protocol to provide the foundation for future design of a larger, multicenter randomized controlled trial.
详细描述
Background:
Lumbar spinal stenosis (LSS) is the most common degenerative condition among older adults, and the leading reason older adults aged 65 and older undergo surgery. LSS is characterized by degenerative changes that lead to loss of intervertebral disc spaces, joint thickening, and enfolding of the ligaments surrounding the spine. These degenerative changes may cause compression of lumbosacral nerve roots resulting in the narrowing of central and vertebral canals known as neurogenic claudication (NC). The symptoms of NC include cramping, numbness or tingling, and muscle weakness in the lower back, buttocks, or one or both legs, with symptoms often intensifying with standing and walking.
The majority of individuals undergoing surgery for LSS are post-retirement age, have chronic low back pain, without access to private rehabilitation. This population is often severely deconditioned prior to surgery with weakness and atrophy of the muscles in the back, core, and lower limb. These preoperative factors have been shown to be predictors for postoperative LSS outcomes. Studies have shown evidence of the effectiveness of prehabilitation programs on post-operative recovery for other musculoskeletal conditions such as total knee arthroplasty. However, there appears to be a lack of high-quality evidence for the effect of prehabilitation interventions in improving outcomes for LSS surgery.
Research Aims:
The purpose of this study is to determine the feasibility of the program of care on a group of patients with LSS undergoing surgery, and determine the feasibility of the protocol for a randomized controlled trial.

盲法说明
Blinding of participants and those delivering the intervention is not possible within rehabilitation trials and blinding of assessors is not possible when participants are not blinded, and outcomes are self-reported. Research coordinators involved in data collection and researchers involved in data analysis, however, will be blinded.
