Safe Return to Play After Concussion

Study Overview
=================
Brief Summary
-----------------
This study will evaluate a combination of a novel Dual-task regime together with other already known tests in terms of defining when an athlete is ready to return to play after a concussion.

Detailed Description
-----------------
In this prospective study, we will evaluate a combination of a novel facilitating agility Dual-task regime together with sport concussion assessment tool -5 (SCAT5), Vestibular/Ocular-Motor Screening for Concussion, Agility T-test, Joint repositions error test and Pain Catastrophizing Scale (PCS) in terms of defining when an athlete is ready to return to play after a concussion. We will investigate if a novel facilitating agility Dual-task test together with already widely used tests, can identify more athletes that after a concussion still isn't ready to return to play, due to a physiological deficit. We will test as many athletes as possible each season and when an athlete suffer a concussion, we will follow them to see when they reach their baseline level. As previous studies show a over representation of new injuries in athletes returning to play after a concussion, we will also register injuries from all included subjects in terms of injuries each year, to evaluate if athletes following our recommendations have a lower injury rate after returning to play after a concussion. We also hope to be able to get more knowledge about how pain catastrophizing is related to duration of concussions symptoms.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Athletes without concussion<br>We follow the athletes in terms of injuries and make a baseline test each season. | Diagnostic Test: Novel facilitating agility dual-task test combined with already known tests<br>* We will investigate if a combination of a novel Dual-task test combined with already known tests can identify more athletes, not ready to return to play, although symptoms of concussion have stopped.<br>|
| Athletes suffering a concussion<br>We follow the athletes in terms of injuries and make a baseline test each season and when they suffer a concussion, then we follow them with the same test as at baseline every 14th day for 3 months, after that they will get enrolled in another study. | Diagnostic Test: Novel facilitating agility dual-task test combined with already known tests<br>* We will investigate if a combination of a novel Dual-task test combined with already known tests can identify more athletes, not ready to return to play, although symptoms of concussion have stopped.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Duration from concussion to physiological rehabilitated with a combination of new and already known test evaluate when the athlete is ready to return to play. | We will by using a combination of new and known tests follow athletes with concussion and their symptoms, and try to get a knowledge about easy accessable test can give coaches a more objective measure for when an athlete is ready to return to play. | as it is a prospective study and we don't know when and how many athletes will get a concussion, then the timeframe is unknown, but we expect to collect data in at least 4 years. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| How pain catastrophizing influence recovery after a concussion | Be measuring pain catastrophizing at baseline and after concussion, we will evaluate if pain catastrophizing correlates with recovery time. | at least 4 years |
