Influence Of Pelvis Impact Angle During A Fall: On The Protective Benefit Of Hip Protectors, Woochol J. Choi, Stephen N. Robinovitch

Physical Therapy Faculty Articles and Research

"Over 90% of hip fractures are due to falls [1]. Laboratory measures have shown that wearable hip protectors reduce impact forces to the proximal femur during a simulated sideways fall on the hip [2, 3]. However, clinical evidence suggests that hip fractures still occur when hip protectors are worn [4]. Furthermore, while falls in real life result in a variety of impact configurations, biomechanical tests to date have focused only on lateral impact to the pelvis. In the current study, we examined how the force reduction provided by wearable hip protectors is affected by pelvis impact configuration during simulated sideways …

Effects Of Pelvis Impact Angle And Hip Muscle Forces On Hip Fracture Risk During A Fall Using An Advanced Hip Impact Simulator, Woochol J. Choi, Stephen N. Robinovitch

Physical Therapy Faculty Articles and Research

"Over 90% of hip fractures in older adults are caused by falls [1]. Whether a given fall will cause hip fracture depends on bone strength, and on the impact force and stress applied to the bone during impact [2]. Improved understanding is required on how peak bone stresses during a fall depend on the mechanics of a fall, and on the state of contraction at the moment of impact of the muscles spanning the hip. Recently, Choi et al showed that, for lateral impact to the hip, peak stresses decrease with increases in hip abductor muscle force [3]. In the …

Connectivity Measures Are Robust Biomarkers Of Cortical Function And Plasticity After Stroke, Jennifer Wu, Erin Burke Quinlan, Lucy Dodakian, Alison Mckenzie, Nikhita Kathuria, Robert J. Zhou, Renee Augsburger, Jill See, Vu H. Lee, Ramesh Srinivasan, Steven C. Cramer

Physical Therapy Faculty Articles and Research

Valid biomarkers of motor system function after stroke could improve clinical decision-making. Electroencephalography-based measures are safe, inexpensive, and accessible in complex medical settings and so are attractive candidates. This study examined specific electroencephalography cortical connectivity measures as biomarkers by assessing their relationship with motor deficits across 28 days of intensive therapy. Resting-state connectivity measures were acquired four times using dense array (256 leads) electroencephalography in 12 hemiparetic patients (7.3 ± 4.0 months post-stroke, age 26–75 years, six male/six female) across 28 days of intensive therapy targeting arm motor deficits. Structural magnetic resonance imaging measured corticospinal tract injury and infarct volume. …

Does Insertion Of Intramuscular Electromyographic Electrodes Alter Motor Behavior During Locomotion?, Jo Armour Smith, Kornelia Kulig

Physical Therapy Faculty Articles and Research

Intramuscular electromyography (EMG) is commonly used to quantify activity in the trunk musculature. However, it is unclear if the discomfort or fear of pain associated with insertion of intramuscular EMG electrodes results in altered motor behavior. This study examined whether intramuscular EMG affects locomotor speed and trunk motion, and examined the anticipated and actual pain associated with electrode insertion in healthy individuals and individuals with a history of low back pain (LBP). Before and after insertion of intramuscular electrodes into the lumbar and thoracic paraspinals, participants performed multiple repetitions of a walking turn at self-selected and controlled average speed. Low …

Reliability Of Precision In Motion Software, Nicole Laura, Kristen Petrillo, Marybeth Grant-Beuttler, Richard Beuttler

Student Scholar Symposium Abstracts and Posters

Objective: Compare data from inexpensive 3-D motion capture system using the Kinect, to the Codamotion, a traditional active marker, motion analysis system. Determine data reliability.

Design: Reliability-method comparison study

Methods: Seventeen subjects (9 females, 8 males) were instructed to walk down marked runway, arms across chest while both systems recorded data. Data was collected with Kinect on the same and opposite side as the Coda. Kinect and Coda data were interpolated and normalized for comparison. A program for heel strike …

Hydatid Cyst Of Thoracic Spine: A Rare Cause Of Paraplegia, Rahul Soangra, Mool Chand Soangra

Physical Therapy Faculty Articles and Research

Primary spinal hydatid cysts are uncommon and extradural involvement is rare. We report an unusual case of Paraplegia due to hydatid disease of primary site of infection extra spinal muscles in thoracic region from T5 to T8 level extending into a daughter cyst at T9 level, is main cause of acute Paraplegia. Magnetic resonance imaging (MRI) showed an extradural round cystic lesion in the spinal canal filling the posterior and left postero-lateral expect at T9 level, markedly compressing the cord. The cyst was removed after laminectomy and opening of the dural sac, with excision of extraspinal mass in left paravertebral …

Physical Therapy Faculty Articles and Research

Objective

This study was undertaken to better understand the high variability in response seen when treating human subjects with restorative therapies poststroke. Preclinical studies suggest that neural function, neural injury, and clinical status each influence treatment gains; therefore, the current study hypothesized that a multivariate approach incorporating these 3 measures would have the greatest predictive value.

Methods

Patients 3 to 6 months poststroke underwent a battery of assessments before receiving 3 weeks of standardized upper extremity robotic therapy. Candidate predictors included measures of brain injury (including to gray and white matter), neural function (cortical function and cortical connectivity), and clinical …
