Stimuli

• Subjects were made to listen to ascending
  auditory beats slow beats (60beats/min), medium
  beats (100 beats /min), fast beats (120
  beats/min).
• Beats were recorded using a synthesizer/sequencer.

11
Analysis

• All the data was acquired at the 100Hz sampling
  frequency
• Data processing and analysis performed on MATLAB
  (The Math Works Inc, US).
• Karl Pearson Coefficient of Correlation

12
Results
Correlation between normal walk and 60 beats /min
Correlation between normal walk and 100 beats
/min  
Correlation between normal walk and 120 beats
/min
13

• Highest positive correlation was found with 100
  beats/ min as compared to other
  tempi(r0.7651,plt0.05).
• Auditory rhythm has a comprehensive effect on
  improvement of gait pattern (stride length) and
  surpasses the effect of load carriage.

Introduction

• Carrying heavy loads is known to cause a change
  in the gait.
• Examined the gait pattern in subjects carrying
  backpack of 12 of their bodyweight while walking
  on a force platform.
• Relationship between gait and synchronous beats
  was explored .
• Determination of the impact of auditory rhythm in
  reducing effect of load on gait parameters
  (stride length) and eventually making them
  symmetric.
