A Mediation Analysis Investigating Dry Needling Treatment Mechanisms in a Chronic Low Back Pain Population

Low back pain is a common problem that many adults experience at some point in their lives. One treatment being studied is dry needling, a technique where a small needle is inserted into a specific area of muscle to help relieve pain. So far, the research on dry needling for low back pain hasn't been clear, and it's hard to know when and for whom it will work best. This study aims to figure out how dry needling works to help people with chronic low back pain by looking at the underlying factors. By understanding how dry needling helps people, we can develop a more targeted approach to treatment, which could lead to better outcomes for people with chronic low back pain. The goal of this study is to identify the factors that make dry needling effective for people with chronic low back pain, so that this this information can be used to provide more personalized and effective care. Eligible participants will attend 5 research sessions lasting approximately 1 hour and complete 2 online surveys. At 3 of those sessions, participants will receive dry needling to their low back. As part of the research, participants will complete questionnaires related to how pain effects their life. Participants will also undergo testing for muscle stiffness, low back mobility and strength, and pain sensitivity. To be included in this study participants must: * Be 18-65 years of age * Have low back pain for at least 3 months

A multicenter randomized controlled trial

A Superiority Trial of Radiofrequency Ablation for Low Back Pain

The purpose of the ASTRAL Study is to evaluate the effectiveness of LRFA (Lumbar radiofrequency ablation) against a control procedure. The ASTRAL Study will enroll individuals with chronic low back pain (CLBP) and randomly assign them to one of three groups: lumbar radiofrequency ablation using conventional electrodes placed parallel to the medial branch nerves (LRFA-C), lumbar radiofrequency ablation using multi-tined electrodes placed perpendicular to the medial branch nerves (LRFA-M), or a simulated radiofrequency ablation procedure.

Biologic Injection For Adults With Lumbar Disc Herniation

The goal of this clinical trial is to find out whether adding a bone-marrow aspirate concentrate (BMAC) injection during surgery can improve recovery in adults undergoing lumbar microdiscectomy for a lumbar disc herniation. The main questions it aims to answer are: * Does the BMAC injection lead to better disc tissue health after surgery (as seen on MRI scans)? * Does the BMAC injection lead to greater improvement in pain and disability compared to surgery alone? Participants will be adults aged 18 and older who are scheduled for lumbar microdiscectomy surgery. Researchers will compare one group of participants receiving the standard-of-care surgery plus the BMAC injection with another group receiving the same surgery without the injection to see if the injection offers added benefit. Participants will: * Have surgery (microdiscectomy) with or without the injection. * Complete pain and disability questionnaires at several times over 2 years. * Undergo MRI scans at baseline and follow-up to assess disc structure and tissue health. * Provide samples of leftover disc or bone-marrow tissue (as applicable) from surgery for analysis.

Connective Tissue Dry Needling for Low Back Pain Related to Local Posterior Superior Iliac Spine Pain

This single-blind randomized controlled trial will aim to determine the effectiveness of a connective tissue dry needling (CTDN) technique, in reducing pain and improving function in individuals with chronic mechanical low back pain associated with pain and tenderness at the posterior superior iliac spine (PSIS). Forty participants with local PSIS-related low back pain will be recruited and randomly assigned into two groups using the block balanced randomization method. The treatment group will receive CTDN targeting connective tissue trigger points around the PSIS in addition to a sacroiliac joint stabilization exercise program, while the control group will perform the same exercise program alone under the supervision of a physiotherapist. The intervention protocol will span two weeks, during which participants will attend three treatment sessions per week, for a total of six sessions. The primary outcome measurement will use the Visual Analog Scale (VAS) to assess pain intensity. The study will measure secondary outcomes through lumbar range of motion (ROM) in flexion and extension and pressure pain threshold (PPT), and Roland-Morris Disability Questionnaire (RMDQ) functional disability and Short Form-36 (SF-36) health-related quality of life. The researchers will assess all outcomes at three time points: baseline and after the first session, and the sixth session, while VAS will receive an additional assessment at the 3-month follow-up. The findings of this study are expected to provide evidence supporting CTDN as a safe, effective, and cost-efficient treatment option for PSIS-related mechanical low back pain.

Percussive Massage Therapy Using Heat Attachment in Chronic Low Back Pain

Low back pain is a global problem that currently affects many people's participation in daily activities, and its prevalence has been increasing over the years. Exercise is among the most effective treatment approaches for reducing and preventing pain and disability related to low back pain. To enhance the effects of exercise, various adjunctive methods may be needed. Local vibration applications delivered through mechanical devices are offer practical and time-efficient application, which may reduce the physiotherapist's manual workload, while also providing potential benefits for patients with musculoskeletal pain. Therefore, the aim of this study is to investigate the effects of Percussive Massage Therapy (PMT) applied using a heat-therapy attachment on pain, disability, spinal mobility, health-related quality of life, kinesiophobia, and patient satisfaction in individuals with chronic low back pain. Patients with chronic low back pain who meet the inclusion criteria will be randomly assigned to either the PMT group or the Control group (CG). All participants will receive a conventional rehabilitation program consisting of supervised exercise training and transcutaneous electrical nerve stimulation (TENS) for 2 weeks, 5 days per week, for approximately 45 to 60 minutes per day. The CG will receive only this conventional rehabilitation program. In addition, participants in the PMT group will receive PMT immediately after each conventional rehabilitation session, consisting of an 8-minute application (4 minutes per side) over the paravertebral muscles using a percussive massage therapy device. Outcome measures will be assessed at baseline and post-treatment (end of week 2). Pain intensity will be evaluated using the Visual Analog Scale (VAS); disability using the Oswestry Disability Index (ODI); spinal flexibility using the finger-to-floor distance test; health-related quality of life using the Short Form-36v2 (SF-36v2); and kinesiophobia using the Tampa Scale for Kinesiophobia (TSK). Treatment satisfaction will be assessed post-treatment using the Global Perceived Effect Scale (GPE), and all data will be recorded on a data collection form.

Psilocybin-Assisted Physical Therapy in Chronic Low Back Pain

The purpose of this research study is to investigate whether a single administration of psilocybin can improve interoceptive awareness (awareness of bodily sensations) in individuals with chronic low back pain undergoing physical therapy, and whether these improvements are linked to pain relief and better physical therapy outcomes.

The main questions it aim to answer are * Does the virtual reality (VR) exercise reduce back pain? * Does it lead to positive changes in how participants perceive pain? * Does it improve back flexibility and reduce disability in daily activities? * Does it help reduce the fear of movement and negative thoughts related to pain? Method Wear a Meta Quest 3s device and participate in a 15-minute virtual reality exercise program called 'FitXR'. Be evaluated for their back pain, sensory test, range of motion, and level of disability in daily life before and after the exercise program. Complete questionnaires about their thoughts and feelings regarding their pain and movement.

Comparison of the Immediate Effect of Passive vs. Passive-Active Hamstring Stretching on Flexibility in Patients With Chronic Low Back Pain

The goal of this clinical trial is to determine whether a combination of passive and active hamstring stretching (PAS) is more effective than passive stretching alone (PS) in improving flexibility in patients with chronic low back pain (CLBP). The main questions it aims to answer are: Does PAS lead to greater improvements in active flexibility compared to PS? Does PAS provide additional benefits in passive flexibility, hamstring stiffness, and pelvic tilt? Researchers will compare the PAS group and the PS group to see if combining passive and active stretching results in greater improvements in flexibility and movement control. Participants will: Perform either PAS or PS stretching exercises as assigned. Undergo measurements of flexibility, hamstring stiffness, and pelvic tilt before and after the intervention. Answer a question about their perceived change in flexibility following the intervention. This study aims to improve rehabilitation strategies for people with CLBP, helping them achieve better movement and pain relief.

Chronic Low Back Pain and Osteopathic Manipulation Treatment

The goal of this clinical trial is to learn if adding Osteopathic Manipulative Therapy (OMT) to the usual medical care provided at the VA (usual VA care) improves treatment outcomes in individuals with chronic low back pain (CLBP). OMT is a set of hands-on techniques a doctor uses to move a patient's muscles and joints which include stretching, gentle pressure, resistance and applying forces to specific areas of the body. This feasibility clinical trial aims to learn about the treatment effects (e.g., effect sizes) of adding OMT to the usual medical care provided at the VA (Usual VA Care) in individuals with LBP.

RE-SCALE: Rehabilitation Engagement and Scaled Access With eXtended Reality and Artificial Intelligence

Background Chronic musculoskeletal pain, especially chronic low back pain (CLBP), is the leading cause of disability worldwide, with a burden expected to rise due to aging and increased longevity. Despite strong evidence supporting multimodal and non-pharmacological management-particularly active physical therapy and self-management-clinical practice still shows low adherence to guidelines, with excessive reliance on imaging, rest, injections, and surgery. Adherence to physical therapy remains one of the most significant barriers: only 40-50% of patients follow prescribed exercise programs. Factors include kinesiophobia, low motivation, and logistical obstacles. Mixed realities (XR: VR, AR, MR) offer solutions by enhancing motivation, reducing barriers, and personalizing rehabilitation. Evidence from systematic reviews shows VR-based rehabilitation can reduce pain, disability, and kinesiophobia, with immersive VR offering additional benefits like presence and habit-building. The SHARESPACE project developed and tested a novel XR rehabilitation environment for CLBP that integrates immersive VR/AR, tele-rehabilitation, real-time motor tracking, avatars for social support, and cognitive architectures for synchronization. Usability studies with patients, clinicians, and the general population confirm its feasibility and acceptance. SHARESPACE has completed phases 1 and 2 of XR intervention development (design and feasibility), now aiming to move to phase 3: large-scale clinical validation. Objectives The main goal is to evaluate not only short-term efficacy but long-term, as well as including more accurate and objective measures. A second objective is the commercial exploitation WE will valuate the efficacy, adherence, and cost-effectiveness of the SHARESPACE XR rehabilitation system compared to usual care in patients with CLBP. Specific objectives include: 1. To conduct a two-site randomized controlled trial (RCT) comparing XR rehabilitation with conventional group rehabilitation. 2. To assess both short-term and long-term outcomes (pain intensity, disability, kinesiophobia). 3. To monitor and improve adherence through ecological momentary assessment and intervention (EMA/EMI) using an app and activity trackers. 4. To enhance motivation and engagement with gamification, social connectedness, and avatar-based interaction. 5. To generate evidence for commercial exploitation and integration into health systems. Methodology The project will conduct a two-site RCT with CLBP patients. Participants will be randomly allocated to: * XR rehabilitation: * Two hospital sessions (traditional + XR-assisted training). * Four remote XR sessions with therapist and patients (L1 avatars). * Continued home-based XR with automated therapist avatars (L3) for up to 120 days. * Integration of EMA/EMI via an app and wearable devices to monitor daily activity, sleep, and adherence, with automated prompts to encourage compliance. * Usual care: standard group rehabilitation sessions for 8 weeks. Primary outcomes: * Pain intensity (VAS, BPI). * Disability (Oswestry Disability Index). * Kinesiophobia (Tampa Scale of Kinesiophobia). Secondary outcomes: adherence rates, motivation, patient satisfaction, feasibility, and cost-effectiveness. Motor performance data will be captured in real time via XR tracking and transmitted to therapists for feedback.

How Osteopathic Treatment Affects the Leg and Foot in People With Low Back Pain

This pilot study will examine whether osteopathic manipulative treatment (OMT) can improve both physical and psychological aspects of chronic low back pain by focusing on the interconnected myofascial system of the back, legs, and feet. Twenty adults with chronic low back pain will receive four OMT sessions over 5-7 weeks. Before and after treatment, the investigators will measure muscle stiffness with ultrasound, plantar pressure during walking with a pressure plate, and patient-reported outcomes on pain, disability, sleep quality, stress, anxiety, depression, pain catastrophizing, and pain self-efficacy using surveys. By linking these objective and subjective measures, the study aims to provide early evidence of how OMT may influence musculoskeletal function, daily activity, and overall well-being, helping to guide future larger studies on treatment strategies for low back pain

The Effect of Attention Distraction on the Adherence to Exercise, in Chronic Low Back Pain Patients.

This randomized controlled trial aims to investigate whether the use of an attention distraction application during exercise increases patient adherence to exercise programs in chronic non-specific low back pain (CNSLBP). In addition, the study will examine whether higher adherence to exercise leads to improved outcomes in pain levels, functional capacity, kinesiophobia, quality of life, central sensitization, and pain catastrophizing.

Predicting Pain and Disability From Voice Recordings in Low Back Pain

Exploring Multidimensional Trajectories in People With Low Back Pain

Low back pain (LBP) is a major health problem in Switzerland and worldwide. Globally, LBP remains the leading cause of years lived with disability and its incidence and associated socioeconomic consequences are predicted to increase in the coming decades. In Switzerland, the condition is one of the most commonly reported physical complaints and negatively affects quality of life, resulting in significant personal burden and personal financial burden. LBP also generates enormous socioeconomic costs, with both direct and indirect costs estimated to reach billions of Swiss francs in Switzerland annually. Therefore, it is essential that LBP prevention, diagnosis, and management are improved. LBP is a multifactorial condition. Social, psychological and biophysical factors, along with comorbidities and genetic factors, influence LBP development and associated disability. In individuals with LBP, psychological factors, such as pain catastrophizing, are associated with higher pain intensity and developing chronic LBP and the associated disability. Among biophysical factors, altered spinal motor behaviour (e.g. smaller trunk movement amplitude) and reduced physical activity have been observed in LBP patients and suggested to influence LBP. However, exactly how all these factors influence LBP and how they are interrelated remains unclear. In particular, the effect of altered spinal motor behaviour on LBP is not understood. However, altered motor behaviour could play an important role in changing LBP and related disability. Therefore, improving our understanding of the patterns of spinal motor behaviour and the interrelationships with other factors in LBP would increase our understanding of LBP progression and could help improve LBP management. This study consists of a 6-month prospective longitudinal cohort observation of spinal motor behavior, physical activity, psychological factors, pain intensity, and disability in LBP patients (300 acute, 300 chronic LBP). Data collection will occur remotely and the frequency of repeated measures will be daily or weekly, depending on the measure. A custom smart-phone application will be used by participants to collect data on spinal motor behavior, psychological factors, pain intensity, and disability. Physical activity will be monitored using a wearable physical activity tracker. Established trajectories of motor behavior will be investigated for potential interrelations with trajectories of other parameters (e.g. pain, psychological factors, and disability), to explore potential causal effects. In addition, risk factors or predictive factors for certain trajectories of motor behavior and other parameters will be identified. As such, this study will allow us to investigate the temporality of these relationships and identify LBP, and in particular spinal motor behavior, phenotypes.

Virtual Reality-Based Rehabilitation in Chronic Low Back Pain: Effects on Muscle Architecture, Balance, and Satisfaction (VR-LBPREHAB)

Chronic low back pain is a common musculoskeletal disorder that causes pain, disability, and reduced quality of life. It is often related to changes in trunk muscle function, thoracolumbar fascia morphology, and impaired balance control. Although conventional motor control exercises are effective, patient motivation and adherence can be limited. Virtual reality (VR)-based rehabilitation offers interactive and engaging environments that may improve compliance and provide additional therapeutic benefits. This study is a randomized controlled trial designed to investigate the effects of VR-based rehabilitation compared with conventional motor control exercises in individuals with chronic low back pain. A total of 40-50 participants aged 18-65 will be recruited and randomly assigned to one of two groups: (1) VR-based rehabilitation or (2) conventional exercise therapy. Both programs will last 8 weeks, delivered three times per week for 40 minutes per session. The primary outcomes include muscle architecture assessed by ultrasound imaging, thoracolumbar fascia morphology, and postural balance control measured by force platform tests. Secondary outcomes include pain intensity, disability, fear-avoidance beliefs, quality of life, and patient satisfaction. The findings of this study are expected to provide new insights into the role of VR in rehabilitation and contribute to evidence-based strategies for managing chronic low back pain. By exploring the effects on both physical and patient-reported outcomes, the study may highlight innovative approaches to improve adherence, reduce pain, and enhance daily function in affected individuals.

Lumber Stabilization Exercise Versus Back Endurance Exercise Among Female University Students

Low Back Pain (LBP) as estimates show that up to 84% of adults will experience LBP at some point in their lifetime, ranking it as a leading cause of disability globally. If the pain lasts more than 12 weeks and remains difficult to manage effectively, it can be called Chronic low back pain (CLBP). Physical therapy interventions play an important role in the non-pharmacological management of CLBP including lumbar stabilization exercises (LSEs) and back extension/endurance exercises which are commonly prescribed modalities that may help in improving the spinal function, reducing pain and improving the quality of life in general.
