Walking Speeds in Patients With Chronic Obstructive Pulmonary Disease

Completed

• Conditions: Chronic Obstructive Pulmonary Disease
• Interventions: Behavioral: Usual and Fast Walking Speeds

• Registration Number: NCT01768754
• Lead Sponsor: West Park Healthcare Centre

Brief Summary

A growing body of evidence suggests that in individuals with chronic lung disease their walk speed is related to their daily function and quality of life. It is possible to assess their usual (routine) and fast walking speeds by getting them to walk in a flat hallway.

In individuals with chronic lung disease, we anticipate that their usual walk speed will be helpful in exercise prescription and use in multidimensional scoring systems. However, it is important to first determine the measurement properties of these two walk speeds.

COPD patients	Usual and Fast Walking Speeds	Usual and Fast Walking Speeds

Primary Outcome Measures

Name	Time	Method
Coefficient of repeatability for usual and fast walk speeds	At baseline and over 1 week period.	Participants will be asked to demonstrate their usual and fast walk speeds over the middle 10 meters of a 30 meter straight track using optical sensors and a hand-held stopwatch. Participants will be instructed to walk at their 'usual' and 'fast' speeds as standardized instructions. The walk test will be repeated after a 5 minute rest and then repeated on two subsequent days, at the same time of day, within one week. This will be simply observational in nature with no planned intervention aside for controlling walking environment.; The primary outcome is going to report a change in walk speeds from baseline and at 1 and 2 days using repeated measures as described by Bland and Altman (reference below).

Secondary Outcome Measures

Name	Time	Method
Agreement in the Bode Index using six minute walk distance and usual walk speed.	Baseline	To assess agreement in the calculated Bode Index using the six minute walk distance versus estimated usual walk speed distance over 6 minutes.
Agreement in walk speeds between optical sensors and stopwatch	Baseline and over 1 week of testing.	Assess agreement between the use of optical sensors and stop watch time for the usual and fast walk speeds.
