Comparison of the PUSH Band 2.0 and Vicon Motion Capture to Measure Concentric Movement Velocity during the Barbell Back Squat and Bench Press.

The purpose of this investigation was to compare concentric movement velocity (CMV) measured with the PUSH Band (v2.0) and a Vicon motion capture system (MC) during the back squat (SQ) and the bench press (BP) resistance exercises (RE). Twelve resistance-trained males (26.

Heart Rate Variability Reflects Similar Cardiac Autonomic Function in Explosive and Aerobically Trained Athletes.

Autonomic cardiac function can be indirectly detected non-invasively by measuring the variation in microtiming of heart beats by a method known as heart rate variability (HRV). Aerobic training for sport is associated with reduced risk for some factors associated with cardiovascular diseases (CVD), but effects on autonomic function in different athlete types are less known. To compare cardiac autonomic modulation using a standard protocol and established CVD risk factors in highly trained intercollegiate athletes competing in aerobic, explosive, and cross-trained sports.

Performance Times for the King-Devick Test in Children and Adolescents.

Objective: To establish the King-Devick test (KD) performance values for children and adolescents.

Design: Prospective cohort.

Setting: Pediatric sports medicine clinics.

Training history constrains postural sway dynamics: A study of balance in collegiate ice hockey players.

Background: Balance and postural control are integral to training and sport performance. Demands on posture are contextual and vary in different ways depending on the specific physical activity.

Research Question: The purpose of this study was to examine the possibility that sustained exposure to environmental constraints, through specific sport participation, might lead to a persistent modification of postural control.

Short Sleep and Adolescents' Performance on a Concussion Assessment Battery: An Experimental Sleep Manipulation Study.

Objective: Correlational studies have linked short sleep to adolescents' report of postconcussion symptoms and cognitive performance during concussion assessments. This study tested whether those are cause-effect relationships.

Design: Three-week randomly counterbalanced, within-subjects, crossover experiment.

Intralabyrinthine schwannomas mimic cochleovestibular disease: symptoms from tumor mass effect in the labyrinth.

Objective: To describe symptoms from intralabyrinthine schwannomas specific from more common vestibular schwannomas of the internal auditory canal or cerebellopontine angle resulting from mass effect from the tumor within the labyrinth.

Patients: Eight patients diagnosed as having intralabyrinthine schwannomas from 2000 to 2014 were examined retrospectively from two tertiary neurotologic centers.

Interventions: Diagnosis of intralabyrinthine schwannoma was made with gadolinium-enhanced magnetic resonance imaging scans.

Cisplatin exposure damages resident stem cells of the mammalian inner ear.

Background: Cisplatin is a widely used chemotherapeutic agent that can also cause ototoxic injury. One potential treatment for cisplatin-induced hearing loss involves the activation of endogenous inner ear stem cells, which may then produce replacement hair cells. In this series of experiments, we examined the effects of cisplatin exposure on both hair cells and resident stem cells of the mouse inner ear.

Tolosa-Hunt syndrome masquerading as Gradenigo syndrome in a teenager.

Tolosa-Hunt syndrome is an idiopathic chronic granulomatous inflammatory process commonly involving the cavernous sinus and the orbit. Symptoms include unilateral eye pain, ophthalmoplegia, headache, and facial pain in the distribution of the upper divisions of the trigeminal nerve and are highly responsive to steroid therapy. Gradenigo syndrome describes extension of a middle ear infection to the petrous apex, with trigeminal pain and ophthalmoplegia, typically responsive to antibiotics and often surgical drainage.

Vestibular tests for rehabilitation: applications and interpretation.

Vestibular function testing plays a critical role in understanding balance disorders. These tests augment a well-performed history and physical exam in providing quantitative information regarding vestibular reflexes, central oculomotor function and postural control strategies. Video-oculography (VOG) and caloric stimulation play a major role in evaluation of both peripheral vestibular and central oculomotor disorders.

Practical guide to choosing an appropriate data display.

The primary objective of graphing research data is to communicate key information visually in a rapid, accurate, and concise way. Graphs might be considered visual take-home lessons of the major point(s) of the manuscript. In choosing a graph, it is tempting to concentrate only on ways of illustrating summary statements characterizing the group(s).

A practical guide to surveys and questionnaires.

Surveys with questionnaires play a vital role in decision and policy making in society. Within medicine, including otolaryngology, surveys with questionnaires may be the only method for gathering data on rare or unusual events. In addition, questionnaires can be developed and validated to be used as outcome measures in clinical trials and other clinical research architecture.

Cisplatin ototoxicity blocks sensory regeneration in the avian inner ear.

Cisplatin is a chemotherapeutic agent that is widely used in the treatment of solid tumors. Ototoxicity is a common side effect of cisplatin therapy and often leads to permanent hearing loss. The sensory organs of the avian ear are able to regenerate hair cells after aminoglycoside ototoxicity.

Epigenetic influences on sensory regeneration: histone deacetylases regulate supporting cell proliferation in the avian utricle.

The sensory hair cells of the cochlea and vestibular organs are essential for normal hearing and balance function. The mammalian ear possesses a very limited ability to regenerate hair cells and their loss can lead to permanent sensory impairment. In contrast, hair cells in the avian ear are quickly regenerated after acoustic trauma or ototoxic injury.

Mutations in a novel gene encoding a CRAL-TRIO domain cause human Cayman ataxia and ataxia/dystonia in the jittery mouse.

Cayman ataxia is a recessive congenital ataxia restricted to one area of Grand Cayman Island. Comparative mapping suggested that the locus on 19p13.3 associated with Cayman ataxia might be homologous to the locus on mouse chromosome 10 associated with the recessive ataxic mouse mutant jittery.
