De La Torre reported the Type, Intensity, Lesion, Time (TILT) formula to evaluate someone who has had a head injury. The author is from the University of Ottawa.
Parameters:
(1) type (behavior and/or response)
(2) intensity (of deficits)
(3) lesion
(4) time between treatment and injury

|
|
61 to 120 minutes after injury |
T2 |
|
|
> 120 minutes after injury |
T3 |
where:
• Starting therapy before injury would only happen in research or surgery.
• How the time is measured could be a source of variability. It may take several minutes after starting an intervention before anything useful is done.
traumaindex =
= SUM(numerical values for the 4 parameters)
Interpretation:
• The TILT can be expressed as the sequence of alphanumeric values for each parameter (TxIxLxTx).
• minimum traumindex: 0
• maximum traumindex: 12
