Trial Outcomes & Findings for Active for Life: Chronic Obstructive Pulmonary Disease (NCT NCT03201198)

NCT ID: NCT03201198

Last Updated: 2024-04-17

Results Overview

The primary dependent variables are the time spent in physical activity (PA) as measured by Upright time monitored in each of the five intervals of the study over a 15-month period. PA will be measured for 7 consecutive days at each measurement using the ActivPal monitor. Each subject must have at least 4 of 7 valid monitoring days in each monitored period. The monitored periods are: baseline (T1), immediate post-intervention (T2), 3-month follow-up post intervention (T3), 6 month follow-up (T4), 12 month follow-up period (T5)

Participant Flow

All subjects recruited had a diagnosis of COPD, were between the ages of 60-85 years, and had an FEV1%predicted less than 80%. Subjects recruited were stratified by gender and FEV1%predicted severity as part of the randomization process.

A total of 182 subjects were enrolled and randomized across both groups. Five subjects were not able to complete baseline assessment leaving 177 randomized subjects who completed baseline assessment.

Active Life
The Active Life intervention includes structured walking, functional circuit training, stretching and behavior/educational components. Active Life: The Active Life intervention focuses on increasing light physical activity (LPA) with 18 sessions over 10 weeks. Each session starts with 20 minutes of walking followed by functional circuit training. The intensity of the exercises and the speed of execution are adjusted to attain a rating of perceived exertion equal to somewhat hard to hard at the end of each circuit. Sessions end with stretching the major muscle groups. Sessions include a behavioral component (self-efficacy enhancing or confidence building) and health education. Subjects are encouraged to increase their total PA by at least 60 minutes a day, focusing on LPA. After completion of the structured intervention subjects will receive 11 5-minute phone coaching sessions and two booster sessions over the next 12 months.
Chair Exercises
The Chair exercise intervention includes chair exercises, behavioral relaxation and health education. Chair exercises: Chair exercises focus on toning and stretching from a seated position with 18 sessions over 10 weeks. Each session includes 5 minutes of slow stretching, 20 minutes of faster paced exercises, 5 minutes of slower paced stretches, followed by 5-10 minutes of massage and imagery. Guided imagery is used to promote relaxation. Health education includes topics of interest to people with COPD such as basic lung physiology, pathophysiology of COPD, commonly used medications, breathing techniques, healthy eating and physical activity, relaxation, travel considerations, and energy conservation. After completion of the structured intervention subjects will receive 11 5-minute phone coaching sessions and two booster sessions over the next 12 months.

PRIMARY outcome

Timeframe: 7 days of continuous activity monitoring w as monitored on each participants at each of five test periods (T1-T5)

Population: Number of participants who were analyzed at each time period (T1-T5) varied due to participants withdrawing, not being available to keep their test appointments, illness, etc. T1=baseline, T2=testing at completion of intervention, T3= 3 months following intervention, T4=6 months following intervention, T5=12 months following intervention

The primary dependent variables are the time spent in physical activity (PA) as measured by Upright time monitored in each of the five intervals of the study over a 15-month period. PA will be measured for 7 consecutive days at each measurement using the ActivPal monitor. Each subject must have at least 4 of 7 valid monitoring days in each monitored period. The monitored periods are: baseline (T1), immediate post-intervention (T2), 3-month follow-up post intervention (T3), 6 month follow-up (T4), 12 month follow-up period (T5)

PRIMARY outcome

Timeframe: 7 days of continuous activity monitoring at each interval

Population: Participant/unit totals differ from overall number analyzed due to invalid or incomplete monitoring of subjects or subjects withdrawals between intervals.

The primary dependent variable are the time spent in sedentary activity as measured as Sedentary Activity (SA) time monitored in each of the five intervals of the study over a 15-month period. SA will be measured for 7 consecutive days at each interval using the ActivPal monitor. Each subject must have at least 4 of 7 valid monitoring days in each monitored period. The monitored periods are: baseline (T1), immediate post-intervention (T2), 3-month follow-up post intervention (T3), 6 month follow-up (T4), 12 month follow-up period (T5)
