The thalamus is a central structure important to modulating and processing all mechanoreceptor input destined for the cortex. A large number of diverse mechanoreceptor endings are stimulated when a high velocity low amplitude thrust is delivered to the lumbar spine during spinal manipulation. The objective of this study was to determine if a lumbar thrust alters spontaneous and/or evoked nociceptive activity in medial thalamic submedius (Sm) neurons. Extracellular recordings were obtained from 94 thalamic Sm neurons in 54 urethane-anesthetized adult Wistar rats...

OBJECTIVES: The purpose of this study was to measure faculty performance of simulated spinal manipulation on a mannequin to help identify teaching standards. METHODS: We measured 3-dimensional transmitted loads using a force plate mounted in the table. Thrusts were delivered through a compliant, jointed mannequin by faculty members along predefined "listings" as taught in lumbopelvic technique courses. RESULTS: Eleven chiropractic faculty members participated, delivering 9 thrusts at 3 loads (light, moderate, and heavy) along 9 different prone and side-posture listings, totaling 81 thrusts per participant...

BACKGROUND: Spinal manipulation (SM) is used commonly for treating low back pain (LBP). Spinal stiffness is routinely assessed by clinicians performing SM. Flexion-relaxation ratio (FRR) was shown to distinguish between LBP and healthy populations. The primary objective of this study was to examine the association of these two physiological variables with patient-reported pain intensity and disability in adults with chronic LBP (>12 weeks) receiving SM. METHODS: A single-arm trial provided 12 sessions of side-lying thrust SM in the lumbosacral region over 6 weeks...

STUDY DESIGN: Online survey study. OBJECTIVE: To determine physical therapists' utilization of thrust joint manipulation (TJM) and their comfort level in using TJM between the cervical, thoracic, and lumbar regions of the spine. We hypothesized that physical therapists who use TJM would report regular use and comfort providing it to the thoracic and lumbar spines, but not so much for the cervical spine. BACKGROUND: Recent surveys of first professional physical therapy degree programs have found that TJM to the cervical spine is not taught to the same degree as to the thoracic and lumbar spines...

BACKGROUND: The involvement of inflammatory components in the pathophysiology of low back pain is poorly understood. It has been suggested that spinal manipulative therapy (SMT) may exert anti-inflammatory effects. PURPOSE: To determine the involvement of inflammation-associated chemokines (CC series) in the pathogenesis of non-specific low back pain and to evaluate the effect of SMT on that process. METHODS: Patients presenting with non-radicular, non-specific low back pain (minimum pain score 3 on 10 point visual analogue scale, VAS) were recruited according to stringent inclusion criteria...

BACKGROUND: Despite emerging evidence to support the use of high velocity thrust manipulation in the management of lumbar spinal conditions, utilization of thrust manipulation among clinicians remains relatively low. One reason for the underutilization of these procedures may be related to disparity in training in the performance of these techniques at the professional and post professional levels. PURPOSE: To assess the effect of using a new model of active learning on participant confidence in the performance of spinal thrust manipulation and the implications for its use in the professional and post-professional training of physical therapists...

Study Design Case series. Background Low back pain (LBP) is an increasing problem in health care. The evidence for the use of spinal manipulative therapy to treat pediatric patients with LBP is minimal. The treatment of pediatrics with manual therapy, particularly spinal manipulation, is controversial within the medical community, primarily with respect to adverse events. The purpose of this case series was to illustrate the feasibility and safety of lumbar manipulation plus exercise in the adolescent population with mechanical LBP...

BACKGROUND AND PURPOSE: Quadriceps weakness is a common finding following knee injuries or surgery, and can be associated with significant functional limitations. This weakness or muscle inhibition may be due to central inhibitory mechanisms, rather than local peripheral dysfunction. Lumbopelvic manipulation has been shown to effect efferent muscle output by altering nociceptive processing. The purpose of this report is to describe the physical therapy management of anterior knee pain and chronic quadriceps weakness utilizing side-lying rotational lumbar thrust manipulation and therapeutic exercise for an individual eight months status-post ACL reconstruction...

This study used an observational design to examine the kinematics of spinal manipulative therapy (SMT) by determining the acceleration characteristics of the manipulative input at the cervical, thoracic, and lumbar spinal regions. Studies of SMT have been restricted to measuring the forces that result from the manipulative input. Several studies have indicated the rate of force development is a key parameter of clinically delivered SMT. Despite this, the movement strategies employed during SMT, including acceleration, have not been directly measured...

OBJECTIVE: The objective of this preliminary study was to determine if high-velocity, low-amplitude spinal manipulation (HVLA-SM) thrust duration alters mechanical trunk activation thresholds of nociceptive-specific (NS) lateral thalamic neurons. METHODS: Extracellular recordings were obtained from 18 NS neurons located in 2 lateral thalamic nuclei (ventrolateral [n = 12] and posterior [n = 6]) in normal anesthetized Wistar rats. Response thresholds to electronic von Frey anesthesiometer (rigid tip) mechanical trunk stimuli applied in 3 lumbar directions (dorsal-ventral, 45° caudal, and 45° cranial) were determined before and immediately after the delivery of 3 HVLA-SM thrust durations (time control 0, 100, and 400 milliseconds)...

Dong-Yuan Cao, Joel G Pickar
We determined whether spinal manipulation could prevent and/or reverse the decrease and increase in paraspinal muscle spindle responsiveness caused respectively by lengthening and shortening histories of the lumbar muscles. Single unit spindle activity from multifidus and longissimus muscles was recorded in the L6 dorsal root in anesthetized cats. Muscle history was created and spinal manipulation delivered (thrust amplitude: 1.0mm, duration: 100ms) using a feedback-controlled motor attached to the L6 spinous process...
