Abstract Background Previous animal models of intervertebral disc degeneration (IDD) rely on open surgical approaches, which confound the degenerative response and pain behaviors due to injury surrounding tissues during approach. To overcome these challenges, we developed a minimally invasive percutaneous puncture procedure induce IDD in rat model. Methods Ten Fischer 344 male rats underwent annular lumbar discs (IVDs) at L2‐3, L3‐4, L4‐5. unpunctured were used as controls. Magnetic...

BACKGROUND: Lumbar intervertebral disc height loss has been associated with spinal change (SHC) and low back pain (LBP), including stenosis. Non-invasive methods to improve require forms of lying down, which are unconducive computer work. OBJECTIVE: Intermittent vertical traction (VT) integrated seated work may provide ergonomic alternatives for increasing SHC promote LBP relief. The primary aim was develop introduce a safe VT prototype dosage induce measure SHC. Prototype comfort ratings...

Biomechanics represents the common final output through which all biopsychosocial constructs of back pain must pass, making it a rich target for phenotyping. To exploit this feature, several sites within NIH Back Pain Consortium (BACPAC) have developed biomechanics measurement and phenotyping tools. The overall aims article were to: 1) provide narrative review as tool; 2) describe diverse array tools outcome measures that exist BACPAC; 3) highlight how leveraging these technologies with...

Assessing physical activity is important in the treatment of chronic conditions, including low back pain (cLBP). ActiGraph™, a widely used monitor, collects raw acceleration data, and processes these data through proprietary algorithms to produce measures. The purpose this study was replicate ActiGraph™ MATLAB test validity method with both healthy controls participants cLBP. code developed ActiGraph™'s counts step algorithms, sum into per minute (CPM), categorize each intensity cut points....

Inertial measurement units (IMUs) provide benefits over the traditional optoelectronic motion capture (OMC) systems in measuring kinematics for low back pain population. The reliability and validity of IMUs to quantify three-dimensional multiple hip/spine segments have not been systematically evaluated. purpose this study was determine repeated-measures concurrent an IMU system spine/hip six common movement assessments. Seventeen participants (32.3 (14.7) years; 11 female) performed two...

OBJECTIVES/GOALS: Chronic low back pain (cLBP) is associated with gait impairments. Gait may serve as an important biomarker for improvement following therapy interventions; however, has not been sufficiently studied in relationship to and function cLBP. METHODS/STUDY POPULATION: Adults cLBP completed a two-minute-walk-test around 37.5 m oval track while wearing inertial measurement unit (IMU—Lifeware LLC, Pittsburgh, PA) over the L5 spinous process. Step time average, step variability,...
