INTRODUCTION Spinal manipulation therapy (SMT) is characterized by specific kinetic and kinematic parameters that can be modulated. The purpose of this study is to investigate fundamental aspects of SMT dose-physiological response relation in humans by varying SMT impulse duration. METHODS Twenty healthy adults were subjected to four different SMT force-time profiles delivered by a servo-cont...

Paraspinal compartment syndrome is a rare cause of lower back pain that remains under-recognized and under-treated and which can result in prolonged and debilitating pain. We present the case of a young female with paramyotonia congenita due to sodium chanelopathy, who developed acute paraspinal compartment syndrome after ingestion of an ephedrine containing proprietary weight loss product. We ...

We report a patient with a wooden foreign body granuloma in the intervertebral disc space being symptomatic 17 years after a paraspinal penetrant trauma. According to the our result of the search for wooden foreign body granulomas, this is the first case suffered from a wooden foreign body granuloma in the intervertebral disc space that reported in the literature. In this report, we emphasized ...

Gout is usually thought of as a peripheral joint disease. However, case reports are available describing gouty lesions in the spine. We report a case of a 51 year old African American woman with no previous history of gout who presented with lower back pain and fever and was found to have multiple small fluid collections in the paraspinal muscles at the L3 to L5 levels on the MRI. She was empir...

BACKGROUND The influence of approach on outcomes of posterior nonfusion stabilization has not been described. This paper analyzes the influence of surgical approach on functional outcome with nonfusion stabilization. METHODS We performed a prospective consecutive cohort outcome analysis of 88 patients who had undergone posterior nonfusion stabilization of the lumbar spine at 178 levels using ...

Introduction. Flexion-extension, or kinematic, MRI has been used to identify dynamic spondylotic spinal cord compression not seen with traditional static MRI. The use of kinematic MRI to diagnose postoperative complications, specifically dynamic compression, is not as well documented. The authors describe a case of dynamic spinal cord compression by the paraspinal muscles causing worsening myel...

BACKGROUND Isocentric C-arm fluoroscopic cone beam CT (CBCT) is a new technique for near real time 3-D volume imaging guidance of percutaneous interventional procedures. In combination with digital flat panel detectors, CBCT has high spatial resolution with isotropic voxel size, allowing for high resolution image reconstruction in any plane, including 3D rotational reconstructions. CBCT combine...

Regulating spinal motion requires proprioceptive feedback. While studies have investigated the sensing of static lumbar postures, few have investigated sensing lumbar movement speed. In this study, proprioceptive contributions to lateral trunk motion were examined during paraspinal muscle vibration. Seventeen healthy subjects performed lateral trunk flexion movements while lying prone with pelv...
