简要总结
Sport-related concussions and traumatic lower body injuries (e.g., anterior cruciate ligament (ACL) tears) occur frequently in high-speed and contact/collision sports contributing to significant time loss from training/competition and potentially devastating long-term performance and health consequences. Neurological impairment following a concussive injury may be subtle, but if missed, may have grave consequences in a high-risk, high-speed sporting context. Recent evidence suggests that the risk of lower body musculoskeletal injury is significantly higher for athletes sustaining a sport-related concussion in the three-month to two-year period following injury. Most injury prevention research to date has focused on modifiable extrinsic risk factors; there is a void or gap on modifiable intrinsic risk factors.
The purpose of this study is to:
- determine the effect of a standardized supplementary pre-season multi-modal neurologic training program, versus usual training, on concussion and/or traumatic lower body injury risk among high-speed/contact/collision sport athletes (primary prevention).
- determine the effect of a standardized supplementary pre-season multi-modal neurologic training program, versus usual training, on concussion and/or traumatic lower body injury severity (time loss from training/competition measured in days, determined from the date of injury to the date a sport medicine physician medically clears the athlete to return to unrestricted training/competition) (secondary prevention).
- determine the effect of a standardized supplementary pre-season multi-modal neurologic training program, versus usual training, on neurologic performance.
The investigators hypothesize that athletes completing the standardized supplementary pre-season multi-modal neurologic training program, compared with usual training, will significantly reduce the participants risk and severity of concussion and/or traumatic lower body injury, and significantly improve neurologic performance.
详细描述
This study will measure multiple neurological systems and brain processes on 400 Canadian high-performance snow sport athletes and elite community ice hockey players in the participants healthy (uninjured) state using reliable assessment technology and techniques. A two-month standardized, pre-season, supplementary multi-modal training program will be prescribed to 200 athletes (intervention cohort) by a team of experienced sport science and medicine professionals targeting the specific intrinsic risk factors of interest identified in the current concussion and ACL prevention literature. The control cohort of 200 athletes will carry out their usual pre-season training programs. At the completion of the two-month training period, the standardized neurological outcome measures completed at baseline will be repeated on all athletes.

结局指标
主要结局
Number of sport-related concussion injuries sustained by participants during the study period as diagnosed by the study physician.
时间窗: Two years
Sport-related concussion diagnosis will be based on clinical judgment by an experienced sport medicine physician based on participant self-report of post-traumatic clinical signs and symptoms, comprehensive neurological examination, and the Sport Concussion Assessment Tool (SCAT5).
Number of acute traumatic lower body injuries sustained by participants during the study period as diagnosed by the study physician.
时间窗: Two years
Acute, traumatic lower body injury to the hip, thigh, knee, leg, ankle, foot including, but not limited to, fracture including avulsion fracture, labral tear, muscle contusion/tear, tendon strain/tear, ligament sprain/tear, meniscus tear, subluxation/dislocation, chondral injury or nerve injury diagnosed by study physician.
次要结局
- Sensorimotor function as measured by the Kinesiological Instrument for Normal and Altered Reaching Movements (Kinarm, Kingston, Ontario, Canada) end-point robotic standard tasks.(Mean change from baseline sensorimotor function on the Kinarm Standard Tasks at 8-weeks post pre-season training.)
- Neuromuscular function as measured by force plates and motion sensor.(Mean change from baseline neuromuscular function on the neuromuscular tasks and wearable sensor at 8-weeks post pre-season training.)
- Visual function as measured by the RightEye eye-tracking system.(Mean change from baseline visual function on the RightEye eye-tracking tasks at 8-weeks post pre-season training.)
- Cognitive function as measured by the computer-based Immediate Post-Concussion Assessment and Cognitive Test (ImPACT).(Mean change from baseline cognitive function on the ImPACT neuropsychological composite scores at 8-weeks post pre-season training.)
- Dynamic neck strength as measured by the TopSpin360 neuromuscular neck-strengthening device.(Mean change from baseline dynamic neck strength at 8-weeks post pre-season training.)
