Physical Therapy Evaluation and Treatment After Concussion/Mild Traumatic Brain Injury.

Over the last decade, numerous concussion evidence-based clinical practice guidelines (CPGs), consensus statements, and clinical guidance documents have been published. These documents have typically focused on the diagnosis of concussion and medical management of individuals post concussion, but provide little specific guidance for physical therapy management of concussion and its associated impairments. Further, many of these guidance documents have targeted specific populations in specific care contexts. The primary purpose of this CPG is to provide a set of evidence-based recommendations for physical therapist management of the wide spectrum of patients who have experienced a concussive event.

A Treatment-Based Profiling Model for Physical Therapy Management of Patients Following a Concussive Event.

SYNOPSIS: Concussions are a public health concern that affects individuals across the life span. The multifaceted effects of concussion warrant an interdisciplinary management strategy that may include physical therapy. However, physical therapists may feel underprepared for clinical decision making following a concussive event. We propose a new treatment-based profiling model to help physical therapists manage patients following a concussive event. This profiling model, based on symptom type and intensity, disability status, and response to movement, prioritizes treatment emphasis on (1) symptom management, (2) movement system optimization, or (3) performance optimization. We consider contextual factors that modify treatment decision making and present examples of each treatment-based profile. J Orthop Sports Phys Ther 2019;49(11):829-841. doi:10.2519/jospt.2019.8869.

Intertester reliability and validity of motion assessments during lumbar spine accessory motion testing.

BACKGROUND AND PURPOSE: Posterior-anterior (PA) assessment of the lumbar spine correlates with radiographic signs of instability and can guide treatment choices, yet studies of the validity of lumbar PA assessments have not been conducted in vivo. The purposes of this study were to determine the intertester reliability of the PA examination in assessing intersegmental lumbar spine motion and to evaluate the validity of this procedure in vivo with dynamic magnetic resonance imaging (MRI). SUBJECTS: Twenty-nine subjects with central lumbar pain participated in this study. METHODS: Two physical therapists independently identified each subject's most and least mobile lumbar segments using the PA procedure. Midsagittal lumbar images were obtained simultaneously during one examiner's assessment. Lumbar segmental mobility was quantified from magnetic resonance images as the change in the intervertebral angle between the resting position and the end range of the PA force application. For each vertebral level tested, maximal sagittal-plane segmental motion was determined. RESULTS: The intertester reliability for identifying the least mobile segment was good (agreement=82.8%, kappa=.71, 95% confidence interval [CI]=.48 to .94), but it was poor for identifying the most mobile segment (kappa=.29, 95% CI=-.13 to .71), despite good agreement (79.3%). The level of agreement between the PA assessments and intervertebral motion measured by MRI was poor (kappa=.04, 95% CI=-.16 to .24, and kappa=.00, 95% CI=-.09 to .08, for the least and most mobile segments, respectively). DISCUSSION AND CONCLUSION: Despite good intertester reliability for identifying the least mobile segment, PA assessments of lumbar segmental mobility did not agree with sagittal-plane motion measured by dynamic MRI. This finding calls into question the validity of the PA procedure for assessing intervertebral lumbar spine motion.

Physical therapists' role in prevention and management of patellar tendinopathy injuries in youth, collegiate, and middle-aged indoor volleyball athletes.

Patellar tendinopathy is highly prevalent in all ages and skill levels of volleyball athletes. To illustrate this, we discuss the clinical, biomechanical, and ultrasound imaging presentation and the intervention strategies of three volleyball athletes at different stages of their athletic career: youth, middle-aged, and collegiate. We present our examination strategies and interpret the data collected, including visual movement analysis and dynamics, relating these findings to the probable causes of their pain and dysfunction. Using the framework of the EdUReP concept, incorporating Education, Unloading, Reloading, and Prevention, we propose intervention strategies that target each athlete's specific issues in terms of education, rehabilitation, training, and return to sport. This framework can be generalized to manage patellar tendinopathy in other sports requiring jumping, from youth to middle age, and from recreational to elite competitive levels.

Assessment of lumbar spine kinematics using dynamic MRI: a proposed mechanism of sagittal plane motion induced by manual posterior-to-anterior mobilization.

STUDY DESIGN: Descriptive study. OBJECTIVE: The purpose of this study was to describe the segmental motion of the lumbar spine during a posterior-to-anterior (PA) mobilization procedure using dynamic magnetic resonance imaging and to propose a mechanism of the lumbar spine's motion as a result of a PA force to a lumbar spinous process. BACKGROUND: Studies reporting kinematic descriptions of PA mobilization are in agreement that motion takes place at all lumbar vertebrae. However, these studies differ in the reported direction of motion. METHODS AND MEASURES: Twenty asymptomatic subjects (mean age +/- SD, 31.1 +/- 7.0 years) participated in this study. For each subject, a PA mobilization force was manually applied at each lumbar spinous process while sagittal plane magnetic resonance images were simultaneously obtained. Intervertebral motion was defined as the change in the intervertebral angle between the resting and end range vertebral positions imparted by the PA pressure. RESULTS: PA force applied at 1 spinous process caused motion at the target vertebra and this motion was propagated caudally and cranially. Motion at the target segment was always into extension. CONCLUSIONS: A PA force applied at a single lumbar spinous process caused motion of the entire lumbar region. The magnitude and direction of intervertebral motions varied with the segment at which the PA force was applied. We postulated that the intervertebral motion induced by a PA force on a spinous process could be in part explained by the morphology of the lumbar spine.
