Effects of a prehabilitation program on patients' recovery following spinal stenosis surgery: study protocol for a randomized controlled trial.

ABSTRACT: Degenerative lumbar spinal stenosis is a prevalent condition in adults over the age of 65 and often leads to deconditioning. Although the benefits of surgery outweigh those of conservative approaches, physical rehabilitation may be used to improve function and to minimize the risk of persistent dysfunction. This study protocol was designed to establish the feasibility of a full-scale randomized controlled trial and to assess the efficacy of an active preoperative intervention program on the improvement of clinical parameters and functional physical capacity in patients undergoing surgery for lumbar spinal stenosis.Forty patients will be recruited and randomly allocated to one of the 2 treatment arms: 6 weeks supervised preoperative rehabilitation program (experimental group) or hospital standard preoperative management (control group). The intervention group will be trained three times per week, with each session aiming to improve strength, muscular endurance, spinal stabilization and cardiovascular fitness. Intensity and complexity of exercises will be gradually increased throughout the sessions, depending on each participant's individual progress. Primary outcomes are level of low back disability and level of pain. Secondary outcomes include the use of pain medication, quality of life, patient's global impression of change, lumbar extensor muscles endurance, maximum voluntary contraction of lumbar flexor and extensor muscles, maximum voluntary contraction of knee extensors, active lumbar ranges of motion, walking abilities, and cardiovascular capacity. Both the primary and secondary outcomes will be measured at baseline, at the end of the training program (6 weeks after baseline evaluation for control participants), and at 6 weeks, 3 and 6 months postoperatively.This study will inform the design of a future large-scale trial. Improvements of physical performances before undergoing lumbar surgery may limit functional limitations occurring after a surgical intervention. Results of this study will provide opportunity to efficiently improve spinal care and advance our knowledge of favorable preoperative strategies to optimize postoperative recovery.US National Institutes of Health Clinical Trials registry NCT02258672 , 10 February 2014.

Project description:IntroductionCentral lumbar spinal stenosis (LSS) is a common cause of pain, reduced function and quality of life in older adults. Current management of LSS includes surgery to decompress the spinal canal and alleviate symptoms. However, evidence supporting surgical decompression derives from unblinded randomised trials with high cross-over rates or cohort studies showing modest benefits. This protocol describes the design of the SUrgery for Spinal Stenosis (SUcceSS) trial -the first randomised placebo-controlled trial of decompressive surgery for symptomatic LSS.Methods and analysisSUcceSS will be a prospectively registered, randomised placebo-controlled trial of decompressive spinal surgery. 160 eligible participants (80 participants/group) with symptomatic LSS will be randomised to either surgical spinal decompression or placebo surgical intervention. The placebo surgical intervention is identical to surgical decompression in all other ways with the exception of the removal of any bone or ligament. All participants and assessors will be blinded to treatment allocation. Outcomes will be assessed at baseline and at 3, 6, 12 and 24 months. The coprimary outcomes will be function measured with the Oswestry Disability Index and the proportion of participants who have meaningfully improved their walking capacity at 3 months postrandomisation. Secondary outcomes include back pain intensity, lower limb pain intensity, disability, quality of life, anxiety and depression, neurogenic claudication score, perceived recovery, treatment satisfaction, adverse events, reoperation rate and rehospitalisation rate. Those who decline to be randomised will be invited to participate in a parallel observational cohort. Data analysis will be blinded and by intention to treat. A trial-based cost-effectiveness analysis will determine the potential incremental cost per quality-adjusted life year gained.Ethics and disseminationEthics approval has been granted by the NSW Health (reference:17/247/POWH/601) and the Monash University (reference: 12371) Human Research Ethics Committees. Dissemination of results will be via journal articles and presentations at national and international conferences.Trial registration numberACTRN12617000884303; Pre-results.

Project description:Because of symptoms, people with lumbar spinal stenosis (LSS) are often inactive, and this sedentary behaviour implies risk for diseases including obesity. Research has identified body mass index as the most powerful predictor of function in LSS. This suggests that function may be improved by targeting weight as a modifiable factor. An e-health lifestyle intervention was developed aimed at reducing fat mass and increasing physical activity in people with LSS. The main components of this intervention include pedometer-based physical activity promotion and nutrition education.The Spinal Stenosis Pedometer and Nutrition Lifestyle INTERVENTION (SSPANLI) was developed and piloted with 10 individuals. The protocol for a randomized controlled trail comparing the SSPANLI intervention to usual non-surgical care follows. One hundred six (106) overweight or obese individuals with LSS will be recruited. Baseline and follow-up testing includes dual energy x-ray absorptiometry, blood draw, 3-day food record, 7-day accelerometry, questionnaire, maximal oxygen consumption, neurological exam, balance testing and a Self-Paced Walking Test.During Week 1, the intervention group will receive a pedometer, and a personalized consultation with both a Dietitian and an exercise specialist. For 12 weeks participants will log on to the e-health website to access personal step goals, walking maps, nutrition videos, and motivational quotes. Participants will also have access to in-person Coffee Talk meetings every 3 weeks, and meet with the Dietitian and exercise specialist at week 6. The control group will proceed with usual care for the 12-week period. Follow-up testing will occur at Weeks 13 and 24.This lifestyle intervention has the potential to provide a unique, non-surgical management option for people with LSS. Through decreased fat mass and increased function, we may reduce risk for obesity, chronic diseases of inactivity, and pain. The use of e-health interventions provides an opportunity for patients to become more involved in managing their own health. Behaviour changes including increased physical activity, and improved dietary habits promote overall health and quality of life, and may decrease future health care needs in this population.Clinicaltrials.gov, NCT01902979.

Project description:IntroductionFrailty is a multidimensional syndrome in which multiple small physiological deficits accumulate gradually, resulting in a loss of physiological reserve and adaptability, putting a patient that is exposed to a stressor at a higher risk of adverse outcomes. Both pre-frailty and frailty are associated with poor patient outcomes and higher healthcare costs. The effect of a prehabilitation programme and standard care on the quality of recovery in pre-frail and frail patients undergoing elective cardiac surgery will be compared.Method and analysisA single-centre, superiority, stratified randomised controlled trial with a blinded outcome assessment and intention-to-treat analysis. Pre-frail and frail patients awaiting elective coronary artery bypass graft, with or without valvular repair/replacement, will be recruited. 164 participants will be randomly assigned to either prehabilitation (intervention) or standard care (no intervention) groups. The prehabilitation group will attend two sessions/week of structured exercise (aerobic and resistance) training, supervised by a physiotherapist, for 6-10 weeks before surgery with early health promotion advice in addition to standard care. The standard care group will receive the usual routine care (no prehabilitation). Frailty will be assessed at baseline, hospital admission and at 1 and 3?months after surgery. The primary outcomes will be participants' perceived quality of recovery (15-item Quality of Recovery questionnaire) after surgery (day 3), days at home within 30 days of surgery and the changes in WHO Disability Assessment Schedule 2.0 score between baseline and at 1 and 3 months after surgery. Secondary outcomes will include major adverse cardiac and cerebrovascular events, psychological distress levels, health-related quality of life and healthcare costs.Ethics and disseminationThe Joint CUHK-NTEC Clinical Research Ethics Committee approved the study protocol (CREC Ref. No. 2017.696?T). The findings will be presented at scientific meetings, in peer-reviewed journals and to study participants.Trial registration numberChiCTR1800016098; Pre-results.
