Concussions – The Benefit of Accurate Baseline Gait Analysis

Crucial discussions surrounding the sports world today focus on athletes’ increased concussion and brain injury risk.  With improvements in training formula, conditioning regimens, and focused performance development, athletes today possess the capability of a harder-hitting and increasingly competitive athletic aptitude. Earlier this month, seventy-five former NFL athletes filed a lawsuit in Los Angeles Superior Court, alleging that the league withheld information regarding the harmful effects of concussions. The players entrusted the league to disclose the harmful effects of repeated head trauma, and claim that a 1994 study performed by the NFL, which took nearly ten years to publish, claim there was “no evidence of worsening injury or chronic cumulative effects” from multiple concussions. Alleged negligence to enact guidelines for regulating post-concussion treatment and return-to-play standards raises interest in studies of the brain. A University of Oregon study shows gait tasks distinguish immediate vs. long-term effects of concussion on balance control.

OptoSource has adopted the idea that an accurate gait-analysis of a healthy athlete can be used as a baseline trend for performance assessment and a return-to-play evaluation. Acquiring a gait print for an athlete in a healthy state will offer objective data that can be compared to a gait analysis after head trauma has occurred. Contrasts in each phase of gait, primarily left to right symmetry, pace, cadence, and power differential will be evident and can be used to determine when an athlete has reached their personal baseline performance values. Obstructed walking tests and mental stimulation while the body is in motion can offer a real correlation between brain function during locomotive states.

OptoSource has began a study of locomotive efficiency and cognitive stimulus with The M.O.G. at Saco Bay Phyiscal Therapy. Testing high school athletes at risk and effected athletes in maintaining a balanced and consistent gait while performing simple cognitive function tests, such as spelling a 5-letter word in reverse, moderate tests of identifying raised fingers on right to left hands, ranging to difficult tasks, such as counting backwards from 93 by seven.
