The maximum score is 84 which is obtained by the sum of all the questions The higher score means high impact on quality of life. This version should be answered by the patients with traumatic brain injury. It is the patient's self- report.

It is useful the study the effect of fatigue in the patients with TBI by using same measurement items so that a more direct comparison can be made. Therefore, the aim of the study is to translate and validate the Modified Fatigue Impact scale in Urdu language The translation and cultural adaptation process would start after obtaining approval from the developer of the original MFIS. This would be done according to WHO guidelines. Translation will be done by symmetrical category. The purpose will be to gain uniformity in the translation of tool in both the Target language and source language. This will involve 5 steps. (Forward translation, synthesis 2, Backward translation, synthesis 2 and pilot testing). Phase 2 would be done according to the guidelines of COSMIN in which psychometric properties will be measured.(reliability, internal consistency, construct validity and factor analysis.)
