A Critical Analysis of the Exercise Prescription and Return to Activity Advice That Is Provided in Patient Information Leaflets Following Lumbar Spine Surgery

Survey of postoperative practices for lumbar spinal stenosis surgery among canadian spinal surgeons and rehabilitation professionals

Background

Postoperative rehabilitation for lumbar spine stenosis (LSS) surgery has been shown to improve functional status postoperatively. However, there is a lack of clinical guidelines on postsurgical recommendations, movement restrictions and rehabilitation practices, which can lead to variations in care. The purpose of this study was to describe current postoperative LSS surgery practices of spine surgeons, physiotherapists, and chiropractors in Canada related to movement restrictions, exercise recommendations and rehabilitation.

Methods

The cross-sectional online survey was distributed to spine surgeons, physiotherapists and chiropractors through newsletters and emails from professional colleges and associations. The surveys involved 3 clinical vignettes of patients with LSS, each with a different type of surgical intervention. Participants were asked to reflect on the cases and provide information on their postoperative practices.

Results

Twenty-six spine surgeons and 151 rehabilitation professionals responded to the survey. Many of the spine surgeons in this study do not (35%) or occasionally refer (27%) their post-LSS surgery patients to outpatient postoperative rehabilitation and do not believe such programs are necessary for all patients (65.4%). There was significant variation on which restrictions should be applied and the length of time that restrictions should be used across all movements and conditions. Rehabilitation professionals observed movement restrictions that aligned with surgeons' recommendations in Cases 1 (decompression) and 3 (long fusion). However, in Case 2 (laminectomy with 1-3 level fusion), they noted more restrictions (eg, pushing, pulling, lifting) than those prescribed by surgeons. The range of exercise recommendations and treatment modalities rehabilitation professionals prescribe vary widely.

Conclusions

There is currently wide variation in care, demonstrating the need to build consensus among spine surgeons and rehabilitation professionals regarding the most optimal postoperative management. In addition, the reasoning behind imposed restrictions should be considered along with surgery-specific factors in refining current postoperative care pathways for the studied patient population.

Early functional training is not superior to routine rehabilitation in improving walking distance and multifidus atrophy after lumbar fusion: a randomized controlled trial with 6-month follow-up

PURPOSE

To investigate the effects of early functional training within a 12-week rehabilitation program on walking distance and lumbar multifidus atrophy following lumbar fusion surgery.

METHODS

A total of 52 patients who underwent lumbar fusion surgery were randomly assigned to either the early functional training group (n = 26) or the routine rehabilitation group (n = 26). The early functional training group (FT group) began a progressive functional training program within the first 12 weeks post-surgery, while the routine rehabilitation group (RH group) started the same training program 12 weeks after surgery. The primary outcome was the walking distance, measured as the 6-minute walk distance (6MWD) at the 3-month, and 6-month follow-up. Secondary outcomes included the cross-sectional area (CSA) of the multifidus muscles, the Visual Analogue Scale (VAS) score, the Oswestry Disability Index (ODI) score, the Short Form 36 Health Survey (SF-36) subscales, including the Physical Component Summary (PCS) and Mental Component Summary (MCS), and the incidence of adverse events. The primary aim was evaluated using a 2-way mixed-model analysis of covariance (ANCOVA), with treatment group as the between-subjects factor and time as the within-subjects factor, after adjusting for baseline measures.

RESULTS

Among the total patients, 38 (73.1%) left with at least one follow-up result, and 29 (55.8%) completed all treatment sessions and obtained an MRI assessment. The mixed-model ANCOVA revealed a significant group-by-time interaction for the 6MWD (F = 6.214, p = 0.003). Patients in the FT group demonstrated superior 6MWD compared to the GH group at 3 months (95% CI: 32.51 to 101.88, p < 0.001). No significant differences were found between the two groups at the 6-month follow-up (95% CI: -15.34 to 54.03, p = 0.271). Regarding secondary outcomes, no significant group-by-time effects were found for ODI (F = 1.221, p = 0.299), PCS (F = 0.166, p = 0.847), or MCS (F = 0.282, p = 0.755). No significant differences were found in the CSA of multifidus muscles between the groups. Nine patients (17.3%) experienced adverse events.

CONCLUSION

Early functional training after lumbar fusion was not superior to routine rehabilitation in improving walking distance, multifidus atrophy, pain, physical function, and quality of life during the 6-month follow-up. Trial registration number (TRN): ChiCTR2300068296.

Rehabilitation after cervical and lumbar spine surgery

The total number of spine surgeries is increasing, with a variable percentage of patients remaining symptomatic and functionally impaired after surgery. Rehabilitation has been widely recommended, although its effects remain unclear due to lack of research on this matter. The aim of this comprehensive review is to resume the most recent evidence regarding postoperative rehabilitation after spine surgery and make recommendations. The effectiveness of cervical spine surgery on the outcomes is moderate to good, so most physiatrists and surgeons agree that patients benefit from a structured postoperative rehabilitation protocol and despite best timing to start rehabilitation is still unknown, most programs start 4-6 weeks after surgery. Lumbar disc surgery has shown success rates between 78% and 95% after 2 years of follow-up. Postoperative rehabilitation is widely recommended, although its absolute indication has not yet been proven. Patients should be educated to start their own postoperative rehabilitation immediately after surgery until they enroll on a rehabilitation program usually 4-6 weeks post-intervention. The rate of lumbar interbody fusion surgery is increasing, particularly in patients over 60 years, although studies report that 25-45% of patients remain symptomatic. Despite no standardized rehabilitation program has been defined, patients benefit from a cognitive-behavioral physical therapy starting immediately after surgery with psychological intervention, patient education and gradual mobilization. Formal spine rehabilitation should begin at 2-3 months postoperatively. Rehabilitation has benefits on the recovery of patients after spine surgery, but further investigation is needed to achieve a standardized rehabilitation approach.

Are healthcare providers offering the proper education for people with low back pain? Content analysis of educational materials

BACKGROUND

Low back pain (LBP) is a prevalent disorder and leading cause of disability worldwide. In Saudi Arabia, patients with LBP are dispensed with educational materials to supposedly facilitate their recuperation.

OBJECTIVE

Appraise the suitability of educational materials provided for people with LBP in Saudi Arabia to determine whether they meet the needs of patients, inform self-management, and are consistent with clinical practice guidelines.

METHODS

A qualitative data collection method was used, and content analyses were conducted to analyse data based on manifest content. Educational items in English and Arabic were collected from relevant health providers in Saudi Arabia.

RESULTS

Seventeen educational materials were sourced from: Ministry of Health hospitals (n= 10), military hospitals (n= 4), private hospitals (n= 2), and a multidisciplinary healthcare association (n= 1). Six identified sub-themes comprise: epidemiological/anatomical data about LBP (n= 6); causes/risk factors (n= 10); exercise (n= 14) and physical activity-related (n= 3) recommendations; treatment-related recommendations (n= 2); general health and lifestyle-related recommendations (n= 8); and postural and ergonomics-related recommendations (n= 13). A common theme emerged, that 'the content of educational materials hindered reassurance and self-management for people with LBP.'

CONCLUSION

The reviewed educational materials fail to adequately report information that assure patients or inform their self-management among the Saudi population with LBP. Further, reviewed items are heavily influenced by the biomedical model of pain.

The Effect of Exercise Interventions After Lumbar Decompression Surgery: A Systematic Review and Meta-Analysis

OBJECTIVE

The purpose of the present systematic review was to evaluate the effectiveness of exercise after lumbar decompression surgery on pain, function, motor-sensory symptoms, and psychosocial parameters.

METHODS

A literature search was conducted with PubMed, Web of Science, Scopus, ScienceDirect, and Cochrane databases. Quality analysis and bias risk assessment were performed with "Physiotherapy Evidence Database" and "Revised Cochrane risk-of-bias tool randomized trials", respectively. A total of 1219 articles were accessed from the relevant databases (PubMed = 97, Cochrane = 61, Web of Science = 97, Scopus = 104, ScienceDirect = 860). Fourteen studies were included in the systematic review. Systematic review results were presented with narrative synthesis due to heterogeneous data. Homogeneous data were given with meta-analysis.

RESULTS

The results demonstrated that strengthening, stabilization, and aerobic exercises provide additional advantages after lumbar decompression than education or clinical advice alone. Studies also emphasized the importance of relaxation, stretching, and mobilization training. The exercise training provided an additional advantage in terms of disability score at 6-12 weeks (short- to moderate-term) follow-up (effect size [ES]: -0.87, 95% confidence interval [CI]: -1.30; -0.45) with high-degree evidence. However, results in the identical pooling for pain scores showed low efficacy (ES: -0.35, 95% CI: -0.76; 0.05). Short Form-36 pooling in the 12-week follow-up demonstrated that exercise training had moderate-degree evidence effectiveness on physical function (ES: 0.51, 95% CI: 0.12; 0.91), bodily pain (ES: 0.52, 95% CI: 0.13; 0.91), and social function (ES: 0.53, 95% CI: 0.13; 0.93).

CONCLUSIONS

The results highlighted the importance of exercise training, particularly strengthening. Meta-analysis results also proved the effectiveness of exercise on disability in the short to medium term.

Physical therapy of patients undergoing first-time lumbar discectomy: a survey of current UK practice

BACKGROUND

The type, timing, and extent of provision of rehabilitation for lumbar discectomy patients in the UK are currently unknown. The aim of this study was to determine the provision and type of rehabilitation for patients undergoing lumbar discectomy in UK neurosurgical centers.

METHOD

Physical therapists involved in treating lumbar discectomy patients in UK neurosurgery centers were invited to complete an online survey that asked about the type, timing (preop, postop), and rehabilitation content for patients undergoing lumbar discectomy.

RESULTS

Seventeen UK neurosurgery centers completed the survey. Twelve (36%) responded from the 33 centers targeted as well as an additional five private centers. All participating centers provided a rehabilitation service for lumbar discectomy patients. Rehabilitation was provided preoperatively in n = 6 (35%) centers, postoperatively as an inpatient in all centers, and postoperatively as an outpatient in n = 14 (82%) centers. Factors that influenced the decision to provide rehabilitation included both external and internal or patient-related factors. Preoperative rehabilitation focused mainly on education, whilst postoperative outpatient rehabilitation focused more on exercises. Rehabilitation consistently included mobility, functional task training, and exercise prescription.

CONCLUSIONS

Whilst all neurosurgical centers in this survey provided some form of rehabilitation for patients undergoing LD surgery, the approach remains inconsistent. Rehabilitation was delivered most frequently postoperatively, with one in three centers providing it preoperatively. Rehabilitation content also varied depending on when it was provided. Further research is needed to determine the optimum timing, contents, and target of rehabilitation for patients undergoing LD surgery.

[Results of the study of functional recovery of professional athletes after minimally invasive lumbar fusion]

OBJECTIVE

To conduct a comprehensive clinical-neurological assessment and to study the results of functional recovery of professional athletes after minimally invasive lumbar interbody fusion.

MATERIALS AND METHODS

The retrospective study included 27 patients-professional athletes who were operated on using minimally invasive decompression and stabilization techniques in the period 2010 to 2019. Clinical-neurological effectiveness was assessed when returning to previous sports activity was 14 (9; 17) weeks and 4 (3; 5) years after surgery.

RESULTS

The follow-up showed a significant improvement in clinical and neurological parameters: persistent elimination of radicular and muscular-skeletal symptoms, a decrease in the level of pain according to a visual analogue scale in the lumbar spine from 68 (61; 85) mm to 3 (2; 11) mm (p=0.002) and in the lower extremities from 84 (78; 91) mm to 1 (0; 3) mm (p=0.001), change in the physical component of health from 26.18 (23.58; 28.37) to 49.82 (49.03; 53.04) (p=0.002) and the psychological component of health from 27.87 (26.22; 29.29) to 52.18 (49.12; 55.66) (p=0.001), significant improvement in the perception of physical activity according to the Borg RPE Scale from 17 (16; 18) points to 9 (8; 9) (p<0.001). In one case (3.7%), the patient did not return to his previous sports career.

CONCLUSION

The use of minimally invasive rigid stabilization in the overwhelming majority of professional athletes made it possible in the shortest possible time to achieve regression of neurological symptoms, reduce pain, improve the quality of life, restore the functional state and return to previous sports activities.

Accelerometry-based physical activity, disability and quality of life before and after lumbar decompression surgery from a physiotherapeutic perspective: An observational cohort study

BACKGROUND

The effect of lumbar decompression on physical activity (PA) measures (measured as number of steps/day and as moderate to vigorous PA (MVPA)) is poorly understood. The aim of the current study was to compare PA in patients before and after lumbar decompression and to determine the association between change in steps/day and MVPA with change in disability, health-related quality of life (HRQOL) and pain.

METHODS

Patients undergoing lumbar decompression surgery were recruited. Steps/day and MVPA MVPA were recorded with an accelerometer. Oswestry Disability Index (ODI), HRQOL (Short Form 36 questionnaire (SF-36)) and pain levels (visual analogue scale (VAS)) were collected prior to surgery and six and twelve weeks postoperatively. Steps/day were compared to the lower bound of steps/day in healthy persons (7,000 steps per day), and the relationship between changes in steps/day, MVPA, ODI, SF-36, and VAS were calculated.

RESULTS

Twenty-six patients aged 37 to 75 years met inclusion criteria and were included in the study. Lumbar decompressions were performed for stenosis and/or disc herniation. Preoperatively, patients took an average 5,073±2,621 (mean±standard deviation) steps/day. At 6 weeks postoperatively, patients took 6,131±2,343 steps/day. At 12 weeks postoperatively, patients took 5,683±2,128 steps/day. Postoperative MVPA minutes per week increased compared to preoperative MVPA (preoperative: 94.6±122.9; 6 weeks: 173.9±181.9; 12 weeks: 145.7±132.8). From preoperative to 12 weeks postoperative, change in steps correlated with MVPA (R=0.775; P<0.001), but not with ODI (R=0.069; P=0.739), SF-36 (R=0.138; P=0.371), VAS in the back (R=0.230; P=0.259) or VAS in the leg (R=-0.123; P=0.550).

CONCLUSIONS

During the first 12 postoperative weeks, daily steps did not reach the lower bound of normal step activity of 7,000 steps/day, however postoperative steps/day were higher than before surgery. Steps/day and MVPA appear to be independent of ODI and SF-36 and represent additional outcome parameters in patients undergoing lumbar decompression surgery and should be considered e.g., by physiotherapists especially from 6 to 12 weeks postoperatively.

Comparing the Effects of Early Versus Late Exercise Intervention on Pain and Neurodynamic Mobility Following Unilateral Lumbar Microdiscectomy: A Pilot Study

STUDY DESIGN

A pilot, two-group pretest-posttest randomized controlled, single blinded study.

OBJECTIVE

Our study aim was to compare the changes in low back pain level, fear avoidance, neurodynamic mobility, and function after early versus later exercise intervention following a unilateral lumbar microdiscectomy.

SUMMARY OF BACKGROUND DATA

Exercise is commonly recommended to patients following a lumbar microdiscectomy although controversy remains as to the timing and protocols for exercise intervention.

METHODS

Forty patients were randomly allocated to early (Group 1) or later (Group 2) exercise intervention group. The low back pain and fear avoidance were evaluated using Oswestry Low Back Pain Disability Questionnaire, Numeric Pain Rating Scale, and Fear-Avoidance Beliefs Questionnaire. The neurodynamic mobility and function were recorded with Dualer Pro IQ Inclinometer, 50-foot walk test, and Patient-Specific Functional Scale. Two-sided t test for continuous variables and chi-square or Fisher exact test for categorical variables were used to compare the two groups' demographic data. The Wilcoxon signed-rank and rank-sum tests were used to compare the changes and the differences, respectively, in low back pain, fear avoidance, neurodynamic mobility, and function between baseline (before surgery) and postoperative repeated measurements (at 1-2, 4-6, and 8-10 wks after surgery) within each study group, after exercise intervention.

RESULTS

Both groups showed a significant decrease in low back pain levels and fear avoidance as well as a significant improvement in neurodynamic mobility and function at 4 and 8 weeks after surgery. However, no significant difference was reported between the two groups.

CONCLUSION

Our study results showed that early exercise intervention after lumbar microdiscectomy is safe and may reduce the low back pain, decrease fear avoidance, and improve neurodynamic mobility and function. A randomized controlled trial is needed to evaluate the early exercise intervention's effectiveness after lumbar microdiscectomy, and thus validate our findings.Level of Evidence: 4.

Early postoperative physical activity and function: a descriptive case series study of 53 patients after lumbar spine surgery

BACKGROUND

The purpose of this prospective case series study was to compare changes in early postoperative physical activity and physical function between 6 weeks and 3 and 6 months after lumbar spine surgery.

METHODS

Fifty-three patients (mean [95% confidence interval; CI] age = 59.2 [56.2, 62.3] years, 64% female) who underwent spine surgery for a degenerative lumbar condition were assessed at 6 weeks and 3- and 6-months after surgery. The outcomes were objectively-measured physical activity (accelerometry) and patient-reported and objective physical function. Physical activity was assessed using mean steps/day and time spent in moderate to vigorous physical activity (MVPA) over a week. Physical function measures included Oswestry Disability Index (ODI), 12-item Short Form Health Survey (SF-12), Timed Up and Go (TUG), and 10-Meter Walk (10 MW). We compared changes over time in physical activity and function using generalized estimating equations with robust estimator and first-order autoregressive covariance structure. Proportion of patients who engaged in meaningful physical activity (e.g., walked at least 4400 and 6000 steps/day or engaged in at least 150 min/week in MVPA) and achieved clinically meaningful changes in physical function were compared at 3 and 6 months.

RESULTS

After surgery, 72% of patients initiated physical therapy (mean [95%CI] sessions =8.5 [6.6, 10.4]) between 6 weeks and 3 months. Compared to 6 weeks post-surgery, no change in steps/day or time in MVPA/week was observed at 3 or 6 months. From 21 to 23% and 9 to 11% of participants walked at least 4400 and 6000 steps/day at 3 and 6 months, respectively, while none of the participants spent at least 150 min/week in MVPA at these same time points. Significant improvements were observed on ODI, SF-12, TUG and 10 MW (p <  0.05), with over 43 to 68% and 62 to 87% achieving clinically meaningful improvements on these measures at 3 and 6 months, respectively.

CONCLUSION

Limited improvement was observed in objectively-measured physical activity from 6 weeks to 6 months after spine surgery, despite moderate to large function gains. Early postoperative physical therapy interventions targeting physical activity may be needed.
