  9. 9. Epochs and Events • Epoch a user defined period (usually 1 minute or 15 seconds) with a single value representing the acceleration in that time period. • Event a continuous physical activity belonging to a single class with a defined start time and duration. It may have another parameter(s) associated with it. Malcolm Granat ISBNPA, San Diego, May 2014
  10. 10. Epochs and Events • Epoch a user defined period (usually 1 minute or 15 seconds) with a single value representing the acceleration in that time period. • Event a continuous physical activity belonging to a single class with a defined start time and duration. It may have another parameter(s) associated with it. Malcolm Granat ISBNPA, San Diego, May 2014

  29. 29. Aim To objectively quantify their mobility challenges The condition: Intermittent Claudication • Due to peripheral arterial disease • Cramping pain in legs on walking • Pain gets worse the longer walking • Pain relieved on resting Challenges in free-living activities: • Interrupted/short walking bouts • Slower walking (Lower cadence) Clinical Challenges – Limited walking ability Malcolm Granat ISBNPA, San Diego, May 2014
