Objectives

To compare the effectiveness of a comprehensive nonsurgical training program to a self-directed approach in improving walking ability in lumbar spinal stenosis (LSS).

A Double‐blind,Randomized, Prospective Study of Epidural Steroid Injection vs. The mild® Procedure in Patients with Symptomatic Lumbar Spinal Stenosis

Background: Epidural steroid injections (ESIs) are commonly used to treat low back pain, including symptomatic lumbar spinal stenosis (LSS). Reports on LSS treatment with ESIs have not differentiated between neurogenic claudication, which is believed to result from nerve root compression, and lumbar radicular pain, thought to be caused by inflammation. While there is overlap between these groups, the clinical relevance of ESI treatment cannot be generalized between these 2 distinct diseases with completely different pathophysiological causes. Methods: This was a double‐blind, randomized, prospective study of ESI vs. the mild procedure in patients with symptomatic LSS, conducted at a single pain management center. Patient reported outcome measures included Visual Analog Scale, Oswestry Disability Index, and Zurich Claudication Questionnaire (ZCQ) patient satisfaction. Results: Thirty‐eight patients were randomized into 2 treatment groups, 21 in mild and 17 in ESI. At 6‐ and 12‐week follow‐up, patients treated with mild reported significantly greater pain decrease over time (P < 0.0001), and significantly greater functional mobility improvement over time (P < 0.0018) than ESI patients. At week 6, mild ZCQ patient satisfaction score of 2.2 indicated a higher level of satisfaction than for ESI with a score of 2.8. In addition, 12‐week ZCQ satisfaction score was 1.8, demonstrating sustained near‐term satisfaction in the mild group. No major mild or ESI device or procedure‐related complications were reported. Conclusions: This study demonstrated that in LSS patients suffering with neurogenic claudication, mild provides statistically significantly better pain reduction and improved functional mobility vs. treatment with ESI.     

The Effect of Spinal Mobilization With Leg Movement in Patients With Lumbar Radiculopathy—A Double-Blind Randomized Controlled Trial

Objectives

To evaluate the effect of spinal mobilization with leg movement (SMWLM) on low back and leg pain intensity, disability, pain centralization, and patient satisfaction in participants with lumbar radiculopathy.

Pain Neurophysiology Education and Therapeutic Exercise for Patients With Chronic Low Back Pain: A Single-Blind Randomized Controlled Trial

Objective

To assess the effect of a pain neurophysiology education (PNE) program plus therapeutic exercise (TE) for patients with chronic low back pain (CLBP).

Osteopathic Manipulative Treatment Including Specific Diaphragm Techniques Improves Pain and Disability in Chronic Nonspecific Low Back Pain: A Randomized Trial

Objective

To investigate the effects of an osteopathic manipulative treatment (OMT), which includes a diaphragm intervention compared to the same OMT with a sham diaphragm intervention in chronic nonspecific low back pain (NS-CLBP).

Effectiveness of Dry Needling Therapy on Pain,Hip Muscle Strength,and Physical Function in Patients With Hip Osteoarthritis: A Randomized Controlled Trial

ObjectiveTo investigate the short-term effects of dry needling (DN) on physical function, pain, and hip muscle strength in patients with hip osteoarthritis (OA).DesignA double-blind, placebo-control, randomized controlled trial.SettingPrivate practice physiotherapy clinic.ParticipantsPatients with unilateral hip OA (N=45) were randomly allocated to a DN group, sham DN group, or control group.InterventionsPatients in the DN and sham groups received 3 treatment sessions. Three active myofascial trigger points (MTrPs) were treated in each session with DN or a sham needle procedure. The treatment was applied in active MTrPs of the iliopsoas, rectus femoris, tensor fasciae latae, and gluteus minimus muscles.Main Outcome MeasuresPhysical function was assessed with the Western Ontario and McMaster Universities (WOMAC) physical function subscale, the timed Up and Go test, and the 40-meter self-paced walk test. Intensity of hip pain related to physical function was evaluated using the visual analog scale and WOMAC pain subscale. The maximal isometric force of hip muscles was recorded with a handheld dynamometer.ResultsSignificant group by time interactions were shown for physical function, pain, and hip muscle force variables. Post hoc tests revealed a significant reduction in hip pain and significant improvements in physical function and hip muscle strength in the DN group compared with the sham and control groups. The DN group showed within- and between-groups large effect sizes (d>0.8).ConclusionsDN therapy in active MTrPs of the hip muscles reduced pain and improved hip muscle strength and physical function in patients with hip OA. DN in active MTrPs of the hip muscles should be considered for the management of hip OA.     

Can Yoga or Physical Therapy for Chronic Low Back Pain Improve Depression and Anxiety Among Adults From a Racially Diverse,Low-Income Community? A Secondary Analysis of a Randomized Controlled Trial

ObjectiveTo determine and compare the effect of yoga, physical therapy (PT), and education on depressive and anxious symptoms in patients with chronic low back pain (CLBP).DesignSecondary analysis of a randomized controlled trial.SettingAcademic safety net hospital and 7 community health centers.ParticipantsA total of 320 adults with CLBP.InterventionYoga classes, PT sessions, or an educational book.Outcome MeasureDepression and anxiety were measured using the Patient Health Questionnaire and Generalized Anxiety Disorder 7-item Scale, respectively, at baseline, 12, and 52 weeks. We identified baseline and midtreatment (6-wk) factors associated with clinically meaningful improvements in depressive (≥3 points) or anxious (≥2 points) symptoms at 12 weeks.ResultsParticipants (female=64%; mean age, 46.0±10.7 years) were predominantly non-White (82%), low-income (<$30,000/year, 59%), and had not received a college degree (71%). Most participants had mild or worse depressive (60%) and anxious (50%) symptoms. At 12 weeks, yoga and PT participants experienced modest within-group improvements in depressive symptoms (mean difference [MD]=?1.23 [95% CI, ?2.18 to ?0.28]; MD=?1.01 [95% CI, ?2.05 to ?0.03], respectively). Compared with the education group, 12-week differences were not statistically significant, although trends favored yoga (MD=?0.71 [95% CI, ?2.22 to 0.81]) and PT (MD= ?0.32 [95% CI, ?1.82 to 1.18]). At 12 weeks, improvements in anxious symptoms were only found in participants who had mild or moderate anxiety at baseline. Independent of treatment arm, participants who had 30% or greater improvement in pain or function midtreatment were more likely to have a clinically meaningful improvement in depressive symptoms (odds ratio [OR], 1.82 [95% CI, 1.03-3.22]; OR, 1.79 [95% CI, 1.06-3.04], respectively).ConclusionsIn our secondary analysis we found that depression and anxiety, common in this sample of underserved adults with CLBP, may improve modestly with PT and yoga. However, effects were not superior to education. Improvements in pain and function are associated with a decrease in depressive symptoms. More research is needed to optimize the integration of physical and psychological well-being in PT and yoga.
