Objective To observe the effect of novel rehabilitation appliance combined with respiratory muscle training in patients with connective tissue-associated interstitial lung disease (CTD-ILD).
Methods A total of 235 CTD-ILD patients were selected by convenience sampling method and randomly divided into control group A, control group B and combined intervention group. The control group A was given routine treatment, the control group B was given respiratory muscle training on the basis of the control group A, and the combined intervention group was given new rehabilitation equipment on the basis of control group B. Forced vital capacity (FVC), inspiratory muscle functionmaximum inspiratory pressure (MIP), peak inspiratory flow (PIF), grip strength test, exercise ability (6 min walking test, 5 times sitting test) and St. George's Respiratory Questionnaire (SGRQ) scores were compared between the three groups before intervention and 3 months after intervention.
Results After 3 months of intervention, the improvement values of FVC, MIP, PIF, grip strength, 6 min walking test distance, 5 times sitting test and SGRQ scores of three groups were compared, and the differences were statistically significant (P < 0.05). The improvement value of grip strength, 6 min walking test, 5 times sitting test and SGRQ score in the control group B showed statistically significant difference compared with those in the combined intervention group (P < 0.05).
Conclusion The novel rehabilitation appliance combined with respiratory muscle training has a good effect in CTD-ILD patients, which can effectively improve the patients' respiratory muscle function and exercise ability by optimizing the rehabilitation process, and improve the patients' quality of life.
