Comparison of Different Massage Techniques Plus Conservative Applications in Low Back Pain
Low Back PainThe aim of this study is to compare of different massage techniques plus conservative aplications in low back pain treatment.

Effects of Strength Training in Chronic Low Back Pain Patients
Chronic Low Back PainAlthough it is known that chronic low back pain (CLBP) have a multifactorial etiology, the investigations about it are mostly specific to each investigation area, making difficult to understand this complex condition. The purpose of the study was to investigate CLBP from a multidisciplinary approach, analyzing biomechanical, morphological and inflammatory parameters aiming to compare the influence of two strength training protocols, one of low intensity and low volume (LIT) and one of high intensity and high volume (HIT). In both experiments, pain intensity and level of functional disability were analyzed (by analogue scale of pain and Oswestry Index), Ground Reaction Forces (GRF - AMTI BP600900 - 2000 force plate), kinematics of lower limbs (Inertial Sensors by Noraxon) and electromyography of the rectus abdominis, external oblique, lumbar multifidus, medial gluteus, vastus lateralis and biceps femoris muscles (TelemyoDTS) during gait and sit-to-stand, inflammatory cytokines by Multiplex in blood samples and cross-sectional area (CSA) of the lumbar multifidus by ultrasound imaging.

Open Facet Joint Denervation in the Treatment of Low Back Pain
Back PainA single blinded RCT for adult patients with spine pain. One group had a lumbar laminectomy with denervation of the facet joint at the level decompressed. The other group had a lumbar laminectomy without facet joint denervation. Both groups had their back pain and functional limitations measured using a 10 cm visual analogue scale and the Oswestry disability index (ODI). All measures were taken before surgery and at patients' 6, 12 and 24 week follow-up clinic visit.

Central Mechanism of Manual Therapy for Low Back Pain
Low Back PainThe purpose of this study is to examine the change of nervous system activity before and after spinal manipulation treatment program in people with low back pain.

Predicting Analgesic Response to Acupuncture: A Practical Approach
Chronic Low Back PainBack PainIn this placebo controlled, patient and assessor blinded clinical trial, the investigators will administer electroacupuncture vs sham electroacupuncture to patients suffering from chronic low back pain, and monitor their symptoms as well as collecting objective outcome measures. The investigators objective is to identify predictors of pain reduction and functional improvement with electroacupuncture vs placebo.

Recurrent Low Back Pain: Linking Mechanism to Outcomes (RCT)
Low Back PainThe purpose of this randomized clinical trial of low back pain exercise programs is to determine if trunk control can be changed by core stabilization exercises. The proposed mechanism of pain reduction and functional improvement of core stabilization exercises is that it enhances trunk movement and muscle control. This study will provide preliminary evidence of the link between patient outcomes and treatment mechanisms. The investigators hypothesize that: both treatment groups will demonstrate significant improvements in pain and function; only subjects in the core stabilization group will demonstrate significant improvements in trunk movement and muscle control.

PRoGReSS-PS: Patient Response to GRraded Sensory Stimulation: A Pilot Study
Low Back PainThe Patient Response to Graded Sensory Stimulation-Pilot Study (PRoGReSS-PS) will measure back pain perceptions in participants who receive either chiropractic treatment or foot massage. The study will also measure back pain and function with research questionnaires and other measures.

A Study to Investigate the Effect of a New Postural Bio-feedback Device on Low Back Pain
Low Back PainA postural bio-feedback device worn by subjects for 4-10 hours a day for 6 days spread across 6 weeks for the sub acute low back pain group and for 8 days spread across 10 weeks for the chronic group. The device records movement and muscle activity data relating to the lower back. Bio-feedback is delivered to the subject as an audible tone, visual cue or vibration and aims to prompt the subject to alter their posture or position in line with recommendations given by the treating practitioner. Four small sensors are adhered to the lower back and send data wirelessly to a data logger carried in the pocket by the subject (the size of a small mobile phone).

Investigation of Trunk Muscle Size and Function in Older Adults With Chronic Low Back Pain
Low Back PainRehabilitative Ultrasound Imaging (US) is a procedure used to evaluate skeletal muscle size and function to inform clinical practice. US has been shown to be a reliable and valid tool for measuring changes in trunk muscle (i.e. abdominal and back muscle) size and activity during sub-maximal contractions in younger populations. Younger adults with low back pain as compared with healthy adults without pain demonstrate smaller back muscle size, lower back muscle activity, and greater back muscle asymmetry (differences in right side compared with left side). No trials are published evaluating muscle adaptations using US in response to clinical treatments for low back pain in the older adult population. Increased muscle size and improved muscle symmetry have been reported in younger adults with low back pain who participate in low back stabilization exercises. These exercises use voluntary contractions of the back muscles with prolonged hold times and low loads. Neuromuscular Electrical Stimulation (NMES) is a treatment modality that increases muscle activity when voluntary activity is impaired and increases muscle size. Most studies assessing muscle size and activity in response to NMES have been conducted in the knee muscles (i.e. the quadriceps), while the impact of NMES on the back muscles remains relatively unexplored. Given the potential to evaluate back muscle size and activity with US, this assessment tool may be used to document muscle adaptations to a clinical intervention in older adults with low back pain. The purpose of this study is to conduct a 6-week clinical trial to determine if NMES plus lumbar stabilization exercises (i.e. NMES AND Stabilization Exercises) is superior to lumbar stabilization exercises (i.e. Moist Heat AND Stabilization Exercises) for improving back muscle size, activity, and side-to-side (i.e. right side versus left side) symmetry in older adults with chronic low back pain (i.e. low back pain of greater than 3 months). Muscle size, activity, and symmetry will be assessed using US before and after the treatments to determine if the treatments positively impact muscle. Secondary clinical measures of success will include improvements in physical, psychological, and social function pre- to post-treatment.
