Chronic obstructive pulmonary disease (COPD)


Subjects attend an initial visit at Glenfield Hospital where once they have consented to participate in the study all the necessary subjective information, including height, weight and blood pressure, will be obtained. Subjects also complete a lung function test and a muscle strength test during this first visit. Once subjects' medical notes have been received and reviewed, subjects attend a second visit at Glenfield Hospital. During the second visit they complete the exercise performance test and fill in three questionnaires. In the time between the two study visits subjects wear an activity monitor on two consecutive weekdays.

Incremental Shuttle Walk Test (ISWT):
Before commencing the test a standardised set of verbal instructions will be played to the subject via a CD player. The test requires participants to walk up and down a 10 metre course which is marked out by two cones placed 9 metres apart. The walking speed is externally paced and is dictated by a pre-recorded audio signal (a 'bleep') which is played on a CD player. The test is maximal and progressive. The test will stop when the subject completes the test, their legs feel too tired, they are too breathless to continue or they fail to keep up with the speed of the test. A failure to keep up with the speed of the test is characterised by a subject being more than 0.5 metre away from the next cone after one verbal instruction to speed up has been given. Subjects will be asked to speed up if they fail to be within 0.5 metre of the next cone before the 'bleep'. HR and Sa02 will be monitored via a pulse oximeter throughout the ISWT and recorded pre and post the ISWT. The Borg breathlessness score will also recorded pre and post and rating of physical exertion (RPE) will be recorded post the ISWT. The test is repeated after a 30-minute rest.
