To explore the effect of MOTOmed intelligent exercise training system on pulmonary rehabilitation in patients with chronic obstructive pulmonary disease (COPD) .

A total of 100 patients with COPD admitted to our hospital from February 2021 to February 2022 were collected and randomly divided into control group and observation group, with 50 cases in each group. The control group received routine pulmonary rehabilitation, and the observation group was treated with MOTOmed intelligent exercise training system intervention on the basis of routine pulmonary rehabilitation for 3 months. Pulmonary function, including forced expiratory volume in one second/forced expiratory volume (FEV₁/FVC), FEV₁ and maximum mid-expiratory flow (MMEF) were measured before and 3 months after treatment. The blood gas indexes including arterial partial pressure of oxygen (PaO₂) and arterial partial pressure of carbon dioxide (PaCO₂) were compared between the two groups. The exercise capacity and quality of life were compared between the two groups, including 6-minute walking test (6-WMT), Short Physical Performance Battery (SPPB) test and St. George's Respiratory Questionnaire (SGRQ) .

There was no significant difference in lung function, blood gas index, exercise capacity and SGRQ score between the two groups before treatment (all P>0.05). Three months after treatment, FEV₁, FEV₁/FVC, MMEF, PaO₂, 6-WMT and SPPB scores in the observation group were significantly higher than those in the control group, while PaCO₂, exercise capacity and quality of life scores were significantly lower than those in the control group (all P<0.05) .

MOTOmed intelligent exercise training system can significantly improve lung function and blood gas index of COPD patients, enhance exercise capacity and improve the quality of life.
