Comparative Study
A method of evaluating helmet rotational acceleration protection using the Kingston Impact Simulator (KIS Unit).
Helmet use is the primary form of head protection against traumatic brain injury. Although helmet designs have proven to be effective in reducing the incidence of skull fracture and major traumatic brain injury, there is little evidence that helmets protect against concussion. Linear and rotational accelerations are important mechanisms underlying concussion, yet current testing protocols do not account for rotational acceleration. Technical considerations have prevented a valid, accurate, and reproducible testing paradigm. Our objectives were to design a novel helmet-testing methodology that accurately and reliably measures rotational acceleration at injury-relevant impact forces, locations, and planes and to evaluate differences in rotational force protection in commercially available helmets. ⋯ KIS is a novel testing methodology that identifies rotation force protection within and between hockey helmet models and manufacturers at different impact location and planes. This information may be useful in improving future helmet design and construction to provide maximal protection against the forces causing concussion.

To compare the injury-related societal costs of an injury prevention program with usual warm up programs for amateur adult male soccer players. ⋯ The injury prevention strategy, The11, did not lower the rate of injuries in adult male soccer players, but the costs per player and per injured player were lower in the intervention group.

A 15-year-old female cheerleader presented to a sports medicine physician for evaluation of a suspected hip flexor injury. Five weeks before presentation, the patient developed acute right lower quadrant (RLQ) pain. She was seen in a local emergency room where her vital signs, abdominal computed tomography, and ultrasound were normal. ⋯ The patient then attended cheerleading camp where her RLQ pain recurred and she was referred to sports medicine for further evaluation. Her examination was significant for exquisite tenderness at McBurney point. She was referred for surgical evaluation for probable appendicitis.

To compare the effectiveness, after 3 months, of a single injection of platelet-rich plasma (PRP), glucocorticoid (GC), or saline in reducing pain in lateral epicondylitis. ⋯ The dropout rate of 58% at 3 months showed that none of PRP, glucocorticoid, or saline injections adequately reduced the pain and disability of lateral epicondylitis.
