Assessment of Resisted Trunk Rotation Exercise With and Without Double-Pulse Breathing Technique on Hockey Shot Velocity: A Pilot Study.

Objective: The purpose of this study was to assess the feasibility of a study to measure the effect of resisted band antirotation exercises with the use of a double-pulse (DP) breathing exercise on slapshot and snap shot velocity and subjective assessment of performance.

Methods: Ten participants between 20 and 30 years of age who play ice hockey were recruited. The study was conducted over 3 weeks, and participants were randomized into 2 groups; group 1: resisted band antirotations with DP (a shout used in martial arts) exercises, and group 2: resisted band antirotations alone.

An Evaluation of PROMIS in Patients With Primary or Metastatic Spine Tumors.

Study Design: Retrospective evaluation of prospectively collected data.

Objective: In spine tumor patients: i) to assess the correlation of Patient-reported Outcomes Measurement Information System (PROMIS) physical function (PF), pain interference (PI), and Depression scores with Oswestry Disability Index (ODI) and Neck Disability Index (NDI) scores; and ii) to assess ceiling and floor effects of PROMIS PF, PI, and Depression domains and the ODI/NDI.

Summary Of Background Data: There remains no widely used patient-reported outcome (PRO) instrument for spine tumor patients.

Preoperative Patient Reported Outcomes Measurement Information System Scores Assist in Predicting Early Postoperative Success in Lumbar Discectomy.

Study Design: Retrospective review of prospective data.

Objective: Determine whether patient reported outcome (PRO) data collected prior to lumbar discectomy predicts achievement of a minimal important difference (MID) after surgery. Compare ability of PRO and clinical information to predict achievement of MID in short term follow-up after discectomy.

Correlation of PROMIS Physical Function and Pain CAT Instruments With Oswestry Disability Index and Neck Disability Index in Spine Patients.

Study Design: A prospective and retrospective cross-sectional cohort analysis.

Objective: The aim of this study was to show that Patient-Reported Outcomes Measurement Information System (PROMIS) computer adaptive testing (CAT) assessments for physical function and pain interference can be efficiently collected in a standard office visit and to evaluate these scores with scores from previously validated Oswestry Disability Index (ODI) and Neck Disability Index (NDI) providing evidence of convergent validity for use in patients with spine pathology.

Summary Of Background Data: Spinal surgery outcomes are highly variable, and substantial debate continues regarding the role and value of spine surgery.

The frequency and reliability of cortical activity using a novel strategy to present pressure pain stimulus over the lumbar spine.

Background: The blocked stimulus presentation strategy, in fMRI study designs, is an important means to study brain function related to a particular stimulus. Specifically, applying pressure stimuli perceived as painful to different anatomical regions has been used to improve our understanding of central sensitization, which is an important clinical phenomenon in chronic pain.

New Method: This paper introduces a novel MR-compatible device used to apply pressure pain stimuli to the lumbar spine of 13 subjects in the supine position.

muCT-based measurement of cortical bone graft-to-host union.

Evaluation of structural bone grafts risk of failure requires noninvasive quantitative predictors of functional strength. We hypothesized that a quantitative graft-to-host union biometric would correlate significantly with biomechanical properties as a surrogate for the risk of fracture. To test this, we developed a novel algorithm to compute the union between host callus and graft, which was termed the union ratio.
