Effectiveness of Incorporating Tai Chi in Pulmonary Rehabilitation Program for Chronic Obstructive Pulmonary Disease Patients in Primary Health Care - Full Text View

Purpose

The purpose of this study was to compare the self-efficacy and quality of life parameters of Chronic Obstructive Pulmonary Disease(COPD)patients who underwent pulmonary rehabilitation with and without Tai Chi elements incorporated in the exercise component in a General Out-patient setting.

Primary Outcome Measures:

Self Efficacy :COPD Self Efficacy Scale (CSES) [ Time Frame: Change in CSES at 6 months post-intervention ] [ Designated as safety issue: No ]
34 item questionnaire consisting of likert scale with 5 responses ranging from "1" indicating " not at all confident" to "5" indicating " very confident" with higher scores representing higher self efficacy. In this study , we used the rating score in the analysis as some items were considered non-applicable in some cases. Rating score from 0.2 to 1 with 0.2 as "not at all confident and 1 as "very confident". The validated Chinese version of CSES was also used
Self- Efficacy : Self-Efficacy for Managing Shortness of Breath ( SEMSOB) [ Time Frame: Change in SEMSOB at 6 months post-intervention ] [ Designated as safety issue: No ]
The SEMSOB is a single question 1-10 scale, valid and reliable instrument that measures patients' overall confidence in keeping breathing difficulties from interfering with what they want to do with higher score indicating greater self efficacy.
SGRQ HKC-Symptoms [ Time Frame: 6 months post-intervention ] [ Designated as safety issue: No ]
SGRQ HKC-Symptoms is calculated by dividing the summed weights by the adjusted maximum possible weight for that component and expressing the result as a percentage. SGRQ-Symptoms score ranged from 0 to 100, where zero indicates best health and 100 indicating maximum disability.
SGRQ HKC-Activity [ Time Frame: 6 months post-intervention ] [ Designated as safety issue: No ]
SGRQ HKC-Activity is calculated by dividing the summed weights by the adjusted maximum possible weight for that component and expressing the result as a percentage. SGRQ-Activity score from 0 to 100, where zero indicates best health and 100 indicating maximum disability.
SGRQ HKC-Impact [ Time Frame: 6 months post-intervention ] [ Designated as safety issue: No ]
SGRQ HKC -Impact is calculated by dividing the summed weights by the adjusted maximum possible weight for that component and expressing the result as a percentage. SGRQ-impact score from 0 to 100, where zero indicates best health and 100 indicating maximum disability.
SGRQ HKC Total [ Time Frame: 6 months post-intervention ] [ Designated as safety issue: No ]
SGRQ HKC-Total is calculated by summing all positive responses in the questionnaire and expressing the result as a percentage of the toal weight for the questionnaire. A total score is calculated from all three components. The SGRQ-total score ranged from 0 to 100, where zero indicates best health and 100 indicating maximum disability.

Secondary Outcome Measures:

6 MWT in Meters [ Time Frame: 6 months post-intervention ] [ Designated as safety issue: No ]
The 6 minute walking test ( 6MWT) was conducted according to protocol recommended by American Thoracic Society (ATS) guidelines to measure functional exercise capacity.This test measured the self paced distance in meters that a patient could quickly walk on a flat, hard surface in a period of 6 minutes.
FVC [ Time Frame: 6 months post intervention ] [ Designated as safety issue: No ]
Forced vital capacity, measured in liters, component of lung function parameters measured by spirometry
FEV1 [ Time Frame: 6 months post-intervention ] [ Designated as safety issue: No ]
Forced expiratory volume in one second, measured in liters, component of lung function test measured by spirometry
FEV1% Pred [ Time Frame: 6 months post-intervention ] [ Designated as safety issue: No ]
Pred FEV1 percent predicted normal values;measured using spirometry
