RIWC_PARA_A029 Gait Analysis

  1. 1. Gait Analysis: Its Use as a Treatment and Rehabilitative Tool Gwenllian Tawy¹, Philip Riches¹, Philip Rowe¹ ¹University of Strathclyde, Glasgow, UK
  2. 2. • Method of analysing movement • Joint kinematics and kinetics • 2D or 3D • Identify pathological movement patterns • Guide rehabilitation and treatment programmes1,2 WHAT IS GAIT ANALYSIS?
  3. 3. CLINICAL USE Rarely used in clinical environments3,4 Problems: • Large footprint • Time consuming • Marker placement protocols • Complicated software • Complicated data • Limited training available to clinicians • Expensive Consequences: • Limited accessibility • Limited evidence of effectiveness
  4. 4. WHY SHOULD WE USE IT? • Gold standard method4 • Non-invasive • Multiple measurements can be recorded simultaneously • Information on functional abilities • Guide rehabilitative and treatment plans • Improve functional outcome following a treatment • Feedback to patients on progress • Evidence of its benefits Aim: Develop a clinic-appropriate motion capture system to assess lower limb function.
  6. 6. ASSESSING RANGE OF MOTION • Important outcome of interest5 • Commonly used in orthopaedics • Traditionally measured with a goniometer 5 • Method is familiar to clinicians
  7. 7. ASSESSING STRENGTH • Informative outcome measure 6 • Not always carried out in a clinical environment 6 • Chair dynamometers/myometers occasionally used 6 • Method familiar to clinicians
  8. 8. ASSESSING GAIT PATTERN AND STABILITY • Walking kinematics • Balance (Motor control) • Identify pathalogical gait • Gauge level of mobility
  9. 9. EASE OF USE • Quick set-up time • Patient friendly assessments • Computer control with footswitch • No need to label markers and process data • Results in real-time • Results in simple formats • Total assessment time is <20 minutes
  10. 10. CONCLUSIONS • Gait Analysis is a gold standard method • Appropriate for a clinical environment • Can record large amounts of data quickly • Real-time • Potential for large-scale use
