[Impact of a Senso-Motoric Intervention in COPD-Patients Participating in an Outpatient Pulmonary Rehabilitation Program: A Randomized Controlled Trial]. / Effektivität eines sensomotorischen Krafttrainings im Rahmen einer ambulanten pneumologischen Rehabilitation bei COPD-Patienten: eine randomisierte kontrollierte Studie.

Objective Exercise training provides a cornerstone of pulmonary rehabilitation (PR) in COPD-patients. However, the components of the training are not yet fully investigated. We conducted a randomized controlled trial to investigate the effectiveness of a sensory-motoric training (SMT) in comparison to a conventional strength training (KT) according to the physical performance. Patients and Methods: 43 COPD patients were randomized and participated either in the intervention group (SMT = 30 minutes SMT per day) or in the control group (KT = 30 minutes KT per day). The SMT was performed as circuit training with five stations. The primary endpoint was the difference between T1 (start of the PR) and T2 (end of the PR) in 5-Times Sit-to-stand test (5-STST) in the intergroup comparison. Secondary endpoints were the intra- and intergroup comparisons of T1 and T2 in the 6-Minute Walk Test (6-MWT), COPD Assessment Test (CAT), St. George Respiratory Questionnaire (SGRQ), Hospital Anxiety- and Depression Scale (HADS) and in lung function. Results No significant differences were seen in the results of the 5-STST between the groups. Likewise, in the 6-MWT, SGRQ, CAT, HADS and lung function. The intragroup comparison between T1 and T2 showed significant differences in 5-STST, 6-MWT, SGRQ, CAT and HADS in both groups. The differences in lung function were not significantly, neither in the inter- nor in the intragroup comparison. Conclusion Similarly to a conventional strength training improvements in exercise capacity could be achieved with a SMT during PR in COPD patients. Further studies are necessary to define the role of the SMT in regards to postural control.
