| C56924 | Gadd Severity Index (SI) - Severity value | GADDSISeverityVal | The value of the Gadd Severity Index (SI) based on head tolerance limit and linear acceleration | The value of the Gadd Severity Index (SI) based on head tolerance limit and linear acceleratio | Severity Index (SI) | Numeric Values |
It was formulated by fitting the Wayne State Tolerance Curve, which is based on skull fracture data. It incorporates impact duration into the assessment of head and brain injury risk. Linear acceleration using "g" as unit, time "ms" as unit. See Ref for equation. The integral is evaluated over the period of time from when the linear acceleration first exceeds 4g to when it returns to 4g after the largest peak. |
