Take previous variables of interest

Stride length

Step length

Velocity

Double support time

Single support time

PAIN!

Inflict acute pain and monitor a change in mechanics of gait

Previous research

Hypothesis

  • A study looked at foot pain and how it reduced stride length, step length, and walking velocity. Also, double support time increased and single support time decreased

  • Disabling foot pain exhibited reduced health-related quality of life, functional impairment, and alterations to foot function that may contribute to an increased risk of falling.

Subjects will display a decrease in step length, stride length and gait velocity at a self-selected pace after adding the painful stimulus

GAITRite Walkway system

"The GAITRite system has a strong concurrent validity and test retest reliability, in addition to being a portable, simple clinical tool for the objective assessment of gait”

GAITRite Electronic Walkway

6 subjects

Webster KE, Wittwer JE, Feller AJ. Validity of the GAITRite walkway system for the measurement of averaged and individual step parameters of gait. Gait & Posture 22 (2005) 317-321.

  • Data was collected and calculated using GAITRite Plus Ver. 4.7 software
  • Exported data to excel
  • Dependent paired t-test with SPSS
  • 3 Male
  • 3 Female

1. Collected required information

2. Subject given specific starting point and direction

3. Subject to remove right shoe

4. Repeat trial with pebble placed in the heel of the right shoe

Each subject completed 2 trials, one without the pebble and one with the pebble

Measuring sensitivity of the GAITRite Electronic Walkway based on gait changes due to a painful stimulus.

  • There was a link between foot pain and altered gait.
  • Although the GAITRite was able to distinguish certain gait changes, not statistically significant.
  • Link between foot pain and altered gait is adapted over time.
  • Single noxious stimulus not enough
  • Future attempts should increase trials and population

Conclusion

  • Gait velocity decreased: 0.25 m/s
  • 148.08 m/s to 147.83 m/s
  • Step length on the right decreased : 3.36 cm
  • 76.95 cm to 73.59 cm
  • Stride length on the right deceased: 6.34 cm
  • 154.37 cm to 148.03

Results

Future Research

  • SPSS (Paired Samples Test)
  • Larger Population
  • Randomized Control Study
  • More Trials

Discussion

Limitations

  • Data Analysis Error
  • Simple Values
  • Small sample size
  • Single Subject study
  • Own Control
  • Acute Insult

Stance on Right (pebble): Decreased

  • Single support decreased from 39.87% to 37.14% of the right stance phase

Stance on Left: Increased

  • Single limb support increased from 38.21% to 39.41% of the left stance phase
  • Double limb support increased from 22.06% to 23.06%
