A Formula to Predict Concussion Symptom Resolution Time

Researchers were looking to find variables that could predict how long someone would be symptomatic. The researchers looked at 53 different variables which included their self-reported symptoms as well as other more objective measures such as Impact testing. The researchers then identified 5 different variables that were predictors of symptom resolution. These variables included ImPACT total symptom score, duration of neck pain, drowsiness, nervousness, and tingling. The researchers then plugged these variables into a formula which they had previously derived and used the significant variables to predict how long patients would suffer from symptoms.

The researchers found that when they used this formula they were able to correctly identify patients who would recover within 10 days 76% of the time. This preliminary formula seems like something to watch for in the future. Enabling practitioners to effectively predict who will recover within 10 days is remarkable. However, This research is limited because the Sample size for this study was only 76 participants. Moreover, the sample was composed of 67% males. The Researchers did note these limitations when concluding their paper.
