FMS Sensitivity and Specificity Flashcards
Functional Movement Screening (FMS)
Interested in FMS since it helps with identifying athletes at risk in order to intervene in them prior to injury occurring (since we struggle to identify athletes at risk we can’t prevent)
Previous Injury Risk
Identifies individuals who have previously been injured (Problem for recalling all details of an injury and how it was done)
Sensitivity and Specificity must be minimized or maximized?
Sensitivity, Maximized and Specificity, Minimized
Positive Likelihood Ratio can be calculated by…
Sensitivity/ 1 - Specificity
Negative Likelihood Ratio can be calculated by…
1 - Sensitivity/ Specificity
Approx. 2 out of 3 athletes who experienced an injury during the following season…
Had an FMS composite score less than or equal to 14
Approx. 3 out of 4 athletes who did not experience an injury during the following season,
Had an FMS composite score greater than or equal to 15
An FMS composite score less than or equal to 14 is about…
2.5 times more likely among athletes who went on to experience an injury than it is among those who did not
An FMS composite score greater than or equal to 15 is about…
Half as likely among athletes who went on to experience an injury than it is among athletes who did not
Approximately 1 out of 3 athletes in this study…
Went on to experience an injury
If an athlete in this population has an FMS composite score of less than or equal to 14…
The pretest estimate of the probability of injury that is (.325) can be revised up to .54
If an athlete in this population has an FMS composite score of greater than or equal to 15…
The pretest estimate of the probability of injury that is (.325) can be revised down to .18
