Low Back Pain Physiotherapy: Does Expectation Really Influence Outcome?

Objectives: Low Back Pain (LBP) is prevalent in most people of working age. The morbidity it causes cannot be taken lightly, as is its economic burden. Physiotherapy has long been prescribed to LBP patients, but treatment outcome measurements, along with the factors influencing it, have not been widely evaluated. In this study, we aim to assess the correlation between patient’s expectation and LBP physical therapy outcome.
 Methods: This was a cross sectional study conducted at physical rehabilitation outpatient clinic in September-December 2019. Participants were patients with LBP who were treated with physical therapy. One series of physical therapy consists of 5 sessions of modality only or modality with exercise therapy; one patient underwent 2 sessions per week. Oswestry disability index (ODI) score was used to evaluate treatment outcome and Stanford Expectation of Treatment Scale score was used to evaluate patient’s expectation. Data was collected twice, before and after 1 series of therapy.
 Results: There were 91 participants included in this study, most of whom were female. Most patients reported a significant decrease in ODI score, irrespective of the LBP chronicity or nutritional status. However, patients who received a combination of physical exercises and modalities reported lower after therapy ODI than those who only received modalities (p=0.009). No correlation was found between positive (p=0.567) or negative (p=0.910) expectations with ODI improvement.
 Conclusion: Our study did not find any correlation between positive or negative expectations towards ODI score improvement.

Unilateral Dynamic Stabilization in Recurrent Lumbar Disc Herniation.

To evaluate the effectiveness and outcomes of unilateral dynamic stabilization in patients with recurrent lumbar disc herniation (RLDH). Patients requiring an operation due to RLDH at the L4?5 level were included in the study.They divided into the following two groups: SD group who had only revision discectomy (n=20) and DD group who had unilateral dynamic rod stabilization with discectomy (n=20). Low back and leg pain were evaluated with the visual analog scale (VAS), and functional results were evaluated with the Oswestry disability index (ODI). The VAS scores were evaluated in two different regions as VAS Low Back (VASLB) and VAS Leg (VASL). The results of each patient were evaluated preoperatively and at 1 and 12 months postoperatively. The anterior disc height (ADH), posterior disc height (PDH), and segmental angle (SA) were measured on the sagittal computed tomography (CT) scans of each patient?s lumbar spine. Modified Pfirrmann grades in the operated and adjacent segments on lumbar magnetic resonance imaging (MRI) were assessed preoperatively and at 12 months postoperatively. A total of, 40 patients (17 women and 23 men; mean age, 47.9 years) were enrolled. There was no statistically significant difference in the VASLB scores between the two groups (p=0.42). The decrease in VASL scores was statistically significant between groups (p < 0.05). A statistically significant decrease in ODI scores was also observed (p < 0.05). When ADH and PDH obtained preoperatively and postoperatively were compared for the SD group, the differences were not statistically significant. Significant differences were found for ADH and PDH obtained preoperatively and postoperatively in the DD group (p < 0.05). However, for SA, the difference was not significant between the two groups (p=0.28). Unilateral dynamic stabilization for RLDH leads to fewer surgical complications and provides sufficient stability by preserving segmental movements.

Effects of a Remotely Delivered Cognitive Behavioral Coaching Program on the Self-Rated Functional Disability of Participants with Low Back Pain

PurposeA remotely delivered cognitive behavioral coaching (CBC) program was offered as a service benefit for commercial health plan members with low back pain (LBP). This study describes changes in self-rated functional disability in a sample of plan members participating in the program (N=423). MethodsIndependent measures included demographics, length of program enrollment, total CBC sessions, and baseline self-reported patient activation and presenteeism levels. Participants rated their functional disability level due to LBP using the Oswestry Disability Index (ODI). Dependent outcomes quantified change in participant functional disability rating (final ODI score minus baseline ODI score). Nonparametric tests compare differences between groups and within-group ODI score change. Two generalized linear models test for associations between independent variables and the ODI change score. ResultsA significant difference between baseline and final ODI scores was observed at the overall program level (p<.001) and within all independent variable categories of interest. Over 68% of total participants (n=289) reported improved functional ability from baseline to final (decrease in ODI score). Participants who completed more CBC sessions demonstrated significantly greater improvement in functional ability (p=.038) compared to those who completed fewer sessions. Participants aged 55 and older were significantly more likely to show deterioration in functional ability from baseline to final (p=.021). ConclusionOutcomes suggest that program participation can influence self-rated functional disability in the management of LBP.

10 kHz spinal cord stimulation for the treatment of non-surgical refractory back pain: subanalysis of pooled data from two prospective studies.

SummarySpinal cord stimulation at 10 kHz is a promising therapy for non‐surgical refractory back pain; however, published data are currently limited. We present a subanalysis of prospectively collected clinical outcome data for non‐surgical refractory back pain patients treated with 10 kHz spinal cord stimulation, from the independent cohorts of two previous studies (SENZA‐RCT and SENZA‐EU). Clinical outcomes were evaluated at pre‐implantation (baseline), 3 months, 6 months and 12 months following 10 kHz spinal cord stimulator implantation. These included: pain relief; responder rate (≥ 50% pain relief from baseline); remission rate (VAS ≤ 3.0 cm); disability (Oswestry Disability Index(ODI)); and opioid use. At 3 months, average back pain decreased by 70% in the combined cohort (60% in the SENZA‐RCT and 78% in the SENZA‐EU cohorts). This was sustained at 12 months, with a 73% back pain responder rate and 68% remission rate in the combined cohort. Leg pain relief results were generally comparable to those for back pain relief. At 12 months, the combined cohort had an average decrease in ODI scores of 15.7% points from baseline and opioid use more than halved. In conclusion, 10 kHz spinal cord stimulation reduced pain, disability and opioid consumption in non‐surgical refractory back pain subjects. Application of this therapy may improve the care of non‐surgical refractory back pain patients and reduce their opioid consumption.

Endoscopic discectomy as an effective treatment of a herniated intervertebral disc.

Prospective observational multicentre two-arm parallel study describing clinical outcome after endoscopic discectomy provided via transforaminal and interlaminar approach. Endoscopic lumbar discectomy (ELD) is apercutaneous minimally invasive procedure for the treatment of herniated lumbar discs. Herniations at lumbar intervertebral disc levels of L1/2, L2/3, L3/4 and L4/5 are mostly accessed by the transforaminal (TF) approach. However, due to the anatomic position of the iliac crest, the L5/S1 level might not be reachable by the transforaminal approach, while the interlaminar (IL) percutaneous approach should be asuitable alternative. In aprospective observational multicentre clinical trial NCT0274311, we compared the clinical outcomes of two groups of patients who underwent ELD via IL (83) and TF (103) approach. The subjects were followed for 12 months via planned examinations by pain physicians. The levels of leg pain and back pain intensity were assessed by an 11-point numerical ratings scale (NRS). Patient's functional disability was assessed by the Oswestry Disability Index (ODI). Study subjects showed a significant decrease in ODI scores in both groups (p<0.001) The values of mean preoperative ODI in TF and IL groups were 39.1±15.7 and 43.4±16, respectively. Postoperative values in the latter groups were 14.8±14.9 and 17.5±14.3, respectively. Significantly lower pain scores for leg pain (p<0.001) and back pain (p<0.001) were also recorded at 12-month follow-ups. Because both procedures are strictly percutaneous; they are now more commonly performed by interventional pain physicians as a safe and effective alternative to open surgical spine procedures (Tab. 3, Fig. 7, Ref. 19).

A Randomized, Multicenter, Double-Blind, Parallel Pilot Study Assessing the Effect of Mechanical Adhesiolysis vs Adhesiolysis with Corticosteroid and Hyaluronidase Administration into the Epidural Space During Epiduroscopy.

Epiduroscopy is a proven method of diagnosis and treatment for chronic radicular pain after spinal surgery, which is known as failed back surgery syndrome (FBSS). The aim of the study was to compare the efficacy of drugs (the enzyme hyaluronidase and corticosteroid DEPO-Medrol) administrated into the epidural space during epiduroscopy, performed within the ventral and ventro-lateral epidural space with a focus on releasing foraminal adhesions. Forty-eight patients with diagnosed FBBS were randomized into two groups before epiduroscopy. Group A received the standard treatment-mechanical lysis of fibrotic tissue in the epidural space. Group B received hyaluronidase and corticosteroid methylprednisolone acetate during the procedure. Subjects were followed for six and 12 months via scheduled double-blinded examinations by pain physicians. Leg and back pain intensity was assessed by an 11-point numerical rating scale, and patients' functional disability was assessed by the Oswestry Disability Index (ODI). Study subjects showed a significant decrease in ODI score in both groups (P < 0.05). Significantly lower pain scores for leg pain (P < 0.05) and back pain (P < 0.05) were also recorded after the six-month follow-up. However, the one-year follow-up showed a return to the baseline ODI values of most monitored pain scores in both groups (P > 0.05). Improvement was only noted on the NRS for back pain at one-year follow-up (P < 0.05). A significant improvement of leg and back pain was found in both groups after six months. ODI was significantly improved only in group B in both the six- and 12-month intervals. Back pain at one-year follow-up was only improved in group B.

Percutaneous vertebroplasty in symptomatic hemangioma versus osteoporotic compression fracture

Background:Percutaneous vertebroplasty (PVP) is more commonly used for osteoporotic compression fractures (OCFs) and osteolytic vertebral body tumors. This study aimed to study the differences between OCFs and vertebral hemangiomas (VHs) treated with PVP.Materials and Methods:Between September 2007 and January 2010, we prospectively treated 28 consecutive patients of OCFs (43 recently symptomatic OCFs) and 24 cases of VHs (26 VHs). We used visual analogue scale (VAS) pain and Oswestry Disability Index (ODI) to evaluate the patients. The followup period in group 1 and 2 were 25.1 months (range 12 - 31 months) and 21.3 months (range 14 - 28 months), respectively. Comparison of means was carried out with the Chi Square Tests, t-test, and N Par-Test for multiple comparisons, whenever appropriate. The level of statistical significance was set at P < 0.05.Results:Following PVP the VAS score decreased to 4.57 and 4.17 in group 1 and 2, respectively. The ODI scores were 32.5% and 30%, respectively. This decrease in ODI scores lasted throughout the followup period.Conclusions:Although the preoperative scores were significantly different between group 1 and 2, there was no significant difference between two groups following the PVP.
