New interactive 3D visualization technique used in pulmonary rehabilitation programme in COPD, a randomized controlled study

Background: The most common symptoms in chronic obstructive pulmonary disease(COPD) are breathing difficulties and physical activity limitations, reduction in health-related quality of life(HRQL) and exacerbations. Pulmonary rehabilitation including education and exercise training improves health. Interactive 3 dimensional visualization(3D) technique used in patient education has not yet been studied. A new education material with 3D technique was developed to enable an increased personalized education within a group setting. Aim: To evaluate differences between education with 3D technique or conventional technique in patient with COPD regarding physical performance, HRQL and self-efficacy. Method: The pulmonary rehabilitation consisted of exercise training during 10 weeks(10w) and a theoretic part presented with 3D technique or conventional technique. Patients were randomized into education by 3D technique(n=27) or conventional technique(n=16). They were assessed at baseline and after 10w regarding physical performance with handgrip test and 6 minute walk test(6MWT), HRQL with the COPD Assessment Test(CAT) and the St George´s Respiratory Questionnaire(SGRQ), and self-efficacy with the SCI Exercise Self Efficacy Scale(ESES). Result: No significant differences between the groups at baseline or after 10w in 6MWT, CAT, SGRQ or ESES. Significant differences were found in the handgrip test at both baseline(p Conclusion: Interactive 3D technique compared to conventional showed no differences and can be used in pulmonary rehabilitation in COPD. More research is needed, i.e. explore the patient perspective of learning by 3D technique.
