Comparison of Effect of Different Methods of Cognitive Loading on Gait of Normal Healthy Students

Arithmetic task: backward counting with serial 3 subtractions out loud. Group 1 and Group 2 participants will be asked to count backwards with serial 3 subtractions out loud while walking 10 meters. There is considerable disruption of performance because of simultaneous articulatory suppression. However, when errors were observed they were calculated to be numerically close to the correct figure which suggests that performance was not completely disrupted by suppression of articulation.

Modified Stroop test or Stroop colour word test: Participants are asked to name the colour of ink that each word is printed. It is the most frequent test used to show attention bias in anxiety patients. This test will appear on the mobile phone in their hands while they walk to increase the effect of cognitive loading.

Carrying a tray with four glasses filled with water. Participants will be asked to hold a tray of glasses filled with water and walk 10 meters to calculate the effect of cognitive loading on gait.
