Preoperative rehabilitation optimization for spinal surgery: a narrative review of assessment, interventions, and feasibility.

PURPOSE: Postoperative physical therapy (PT) is a cornerstone of orthopedic and musculoskeletal rehabilitation, proven to provide various positive clinical benefits. However, there is a paucity of literature evaluating the utility of preoperative rehabilitation specific to spine surgery. Thus, this review article aims to provide an overview of previously published studies discussing the efficacy of preoperative rehabilitation programs and its role in spinal surgery. Special emphasis was given to preoperative frailty assessments, physical performance tests, interventional strategies, feasibility, and future directions. METHODS: We performed a literature review using PubMed, Google Scholar, EMBASE, and PubMed Central (PMC) using directed search terms. Articles that examined preoperative rehabilitation in adult spine surgery were compiled for this review. Prehabilitation programs focused on exercise, flexibility, and behavioral modifications have been shown to significantly improve pain levels and functional strength assessments in patients undergoing elective spine surgery. In addition, studies suggest that these programs may also decrease hospital stays, return to work time, and overall direct health care expenditure costs. Screening tools such as the FRAIL scale can be used to assess frailty while physical function tests like the timed-up-and go (TUGT), 5 repetition sit-to-stand test (5R-STST), and hand grip strength (HGS) can help identify patients who would most benefit from prehabilitation. CONCLUSIONS: This review illustrates that prehabilitation programs have the potential to increase quality of life, improve physical function and activity levels, and decrease pain, hospital stays, return to work time, and overall direct costs. However, there is a paucity of literature in this field that requires further study and investigation.

Completion of a formal physiotherapeutic scoliosis-specific exercise training program for adolescent idiopathic scoliosis increases patient compliance to home exercise programs.

INTRODUCTION: Physiotherapeutic Scoliosis-Specific Exercise (PSSE) is a conservative approach for management of adolescent idiopathic scoliosis (AIS). Although there is Level I evidence for the efficacy of PSSE, compliance in the teenage population remains in question. The purpose of this study is to investigate the association between completion of formal PSSE training and compliance to prescribed home exercise programs (HEP). METHODS: Patients with AIS evaluated at our institution between 2013 and 2015 with a minimum of one PSSE session were enrolled. A chart review and questionnaire completed by caregivers was utilized to assess HEP compliance following the final PSSE session at 1 week, 3 months, 1 year, and 2 years. Patients were divided into two groups, those completing formal training (10 or more PSSE sessions), and those who did not complete formal training (fewer than 10 sessions). RESULTS: 81 patients were identified (mean age of 13.1 years; major curve of 31.3°). Patients who completed training demonstrated 50% compliance at 1 week (vs. 25.6% for non-completers, Odds Ratio (OR): 2.9, p = 0.027), 41.2% at 3 months (vs. 18.9% for non-completers, OR: 3.0, p = 0.044), 23.5% at 1 year (vs. 13.5% for non-completers, OR: 2.0, p = 0.281), and 25.7% at 2 years (vs. 13.5% for non-completers, OR: 2.2, p = 0.197). The mean HEP duration (minutes) in patients who completed training was higher at 1 week (80.8 vs. 48, p = 0.010), 3 months (64.6 vs. 23.7, p ≤ 0.001), 1 year (35.3 vs. 22.7, p = 0.270), and 2 years (34.3 vs. 18.9, p = 0.140). CONCLUSION: Patients who completed PSSE training maintained higher HEP compliance.

Establishing consensus on the best practice guidelines for the use of bracing in adolescent idiopathic scoliosis.

STUDY DESIGN: Survey. OBJECTIVES: Bracing is the mainstay of conservative treatment in Adolescent Idiopathic Scoliosis (AIS). The purpose of this study was to establish best practice guidelines (BPG) among a multidisciplinary group of international bracing experts including surgeons, physiatrists, physical therapists, and orthotists utilizing formal consensus building techniques. Currently, there is significant variability in the practice of brace treatment for AIS and, therefore, there is a strong need to develop BPG for bracing in AIS. METHODS: We utilized the Delphi process and the nominal group technique to establish consensus among a multidisciplinary group of bracing experts. Our previous work identified areas of variability in brace treatment that we targeted for consensus. Following a review of the literature, three iterative surveys were administered. Topics included bracing goals, indications for starting and discontinuing bracing, brace types, brace prescription, radiographs, physical activities, and physiotherapeutic scoliosis-specific exercises. A face-to-face meeting was then conducted that allowed participants to vote for or against inclusion of each item. Agreement of 80% throughout the surveys and face-to-face meeting was considered consensus. Items that did not reach consensus were discussed and revised and repeat voting for consensus was performed. RESULTS: Of the 38 experts invited to participate, we received responses from 32, 35, and 34 for each survey, respectively. 11 surgeons, 4 physiatrists, 8 physical therapists, 3 orthotists, and 1 research scientist participated in the final face-to-face meeting. Experts reached consensus on 67 items across 10 domains of bracing which were consolidated into the final best practice recommendations. CONCLUSIONS: We believe that adherence to these BPG will lead to fewer sub-optimal outcomes in patients with AIS by reducing the variability in AIS bracing practices, and provide a framework future research. LEVEL OF EVIDENCE: Level IV.

Surgeon Attitudes Toward Physiotherapeutic Scoliosis-Specific Exercises in Adult Patients With Spinal Deformities.

BACKGROUND: Physiotherapeutic scoliosis-specific exercise (PSSE) has proven to be an important treatment for patients with adolescent idiopathic scoliosis. However, there is a lack of understanding of the role of PSSE in older adults with spinal deformity. METHODS: An electronic, 14-question survey with questions regarding the use of physical therapy (PT) and PSSE for adult spinal deformity was administered to all Scoliosis Research Society members. Physician location, age, specialty, years in experience, and management preferences were quantified using descriptive analyses. RESULTS: Of the 98 surgeons who participated in this study, the majority of respondents were from North America (71.1%), and the mean age was 51.87 ± 10.93 years; approximately 98% of respondents were orthopedic surgeons, and 48.0% had been in practice for more than 21 years. Sixty-four percent reported they prescribed PT in their practice, with 52% of respondents often using PT as nonoperative treatment; 21.4%, preoperative; and 40.8% postoperative. The primary reason for PT referral was persistent pain (40.3%), followed by impairments to the patient's balance or gait (34.3%) and difficulty with daily living activities (25.4%). The primary indications for not referring postoperative patients to PT were lack of perceived value from PT (50%), lack of evidence supporting the benefits from PT (31.3%), and a lack of physical therapists appropriately trained for scoliosis (18.8%). Of the respondents, 74% were familiar with PSSE and 66% were comfortable prescribing PSSE postoperatively. In addition, 28% of respondents agreed that >12 weeks postoperation was the ideal time for PSSE referral, followed by 6 to 8 weeks postoperation (26.2%) and immediately postoperation (18%). CONCLUSIONS: The results show that the majority of respondents prescribed PSSE solely for nonoperative treatment. Respondents who did not prescribe PSSE reported skepticism due to a lack of perceived value. This suggests the need for further research into the benefits of PSSE. LEVEL OF EVIDENCE: 5. CLINICAL RELEVANCE: Physiotherapeutic Scoliosis Specific Exercises (PSSE) is an important non-operative treatment for patients with Adolescent Idiopathic Scoliosis (AIS) but is understudied in Adult Spinal Deformity (ASD) patients, suggesting further clinical research. This study demonstrates that only two-thirds of the respondents familiar with PSSE were comfortable prescribing PSSE postoperatively suggesting the need for further research into the effectiveness and benefits of PSSE in ASD patients.
