Use of Wii computer for enhanced exercise in COPD patients.
Behavioral: Use of Home exercise computer program
After a 30-minute rest period the study patient performed a series of 4 representative exercises from the Wii under direct supervision by an investigator. Five minutes' rest was allotted between each exercise. The patient was instructed to exercise at his/her own pace, with a maximal duration of 5 minutes per exercise. The Oxycon Mobile was worn throughout this exercise, and the metabolic measurements listed above were recorded over the last 30 seconds of each exercise. The exercises included running in place, upper arm movements, stepping in place, and obstacle course.
After an initial clinical assessment, which included spirometry or review of recent spirometric data, patients performed an ISWT, as described above. Those who required using supplemental oxygen carried their own tanks. For those who had participated in the pilot study, another ISWT was performed at this time.
Following a 1-hour rest period, baseline outcome assessments were obtained. These included:
- The Endurance Shuttle Walk Test (ESWT) 9 After an initial warm-up at a slow walk speed, patients walked at an external pace set by an audio source at approximately 85% of their maximal determined by the ISWT. Time at this speed was recorded.
- Health status. This was measured using the self-reported Chronic Respiratory Questionnaire (CRQ-SR) which has domains of dyspnea, fatigue, emotion and mastery as well as a total score.
- Dyspnea. This was measured using the 5-point Medical Research Council (MRC) rating.
- The number of sit-to-stand repetitions in 30 seconds. The patient was seated on a chair without arms and instructed to stand up (without using his/her arms) and then return to the seated position as many times as possible in a 30-second period. This test was first demonstrated by an investigator and then performed by the patient.
- The number of arm lift repetitions in 60 seconds.11 The subject was instructed to stand and repetitively raise a wooden dowel, from a position resting against the thighs, up to eye level with the arms straight at the elbows, and the return to original position. The maximum number of completed repetitions in 60 s was recorded.
Patients returned after a 6 week non-intervention period when the above-listed outcomes were repeated. They were then given instructions on how to use the Wii Fit unit to perform exercise at home and instructed to perform at least 30 minutes of specified exercises on most days of the week. The required exercises, in sequence, were 1) "Basic Run" (warm up exercise); 2) "Bird's Eye, Bull's-Eye" (mostly upper arm exercise); 3) "Free Step" (mostly lower extremity exercise); 4) "Obstacle Course" (upper and lower extremity exercise); and 5) "Basic Run" (cool down exercise). Additional, ad-lib exercises using this device were allowed. They were instructed to maintain a diary, recording the dates of each session and the total number of minutes devoted to this exercise. Other exercises not based on this system were allowed but not recorded.
