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

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

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

Introduction
Hand dexterity is multifaceted and essential to the performance of daily tasks. Timed performance and precision demands are the most common features of quantitative dexterity testing. Measurement concepts such as rate of completion, in-hand manipulation and dynamic force control of instabilities are being integrated into assessment tools for the pediatric population.
Purpose
To review measurement concepts inherent in pediatric dexterity testing and introduce concepts that are infrequently measured or novel as exemplified with two assessment tools.
Methods
Measurement concepts included in common assessment tools are introduced first. We then describe seldom measured and novel concepts embedded in two instruments; …
Clinical Assessment Of The Infant And Child Following Perinatal Brachial Plexus Injury, Susan V. Duff, Carol Dematteo
Clinical Assessment Of The Infant And Child Following Perinatal Brachial Plexus Injury, Susan V. Duff, Carol Dematteo
Physical Therapy Faculty Articles and Research
Introduction
After perinatal brachial plexus injury (PBPI), clinicians play an important role in injury classification as well as the assessment of recovery and secondary conditions. Early assessment guides the initial plan of care and influences follow-up and long-term outcome.
Purpose
To review methods used to assess, classify and monitor the extent and influence of PBPI with an emphasis on guidelines for clinicians.
Methods
We use The International Classification of Functioning, Disability, and Health (ICF) model to provide a guide to assessment after PBPI for rehabilitation clinicians.
Discussion
With information gained from targeted assessments, clinicians can design interventions to increase the …

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 …
