Overview
The aim was to investigate the effectiveness of inspiratory muscle training on dyspnoea, pulmonary function, respiratory muscle strength, cough capacity, functional exercise capacity, substance craving, depression, anxiety and quality of life in individuals with substance use disorder.
Detailed description
In recent years, substance use has increased among young people in our country, and studies investigating the negative effects of substances on pulmonary health have also increased. It has been emphasized in the literature that the most appropriate features should be determined for the exercise program in the treatment of individuals with SUD. Although studies in the literature have reported that substance use affects respiratory functions and creates a restrictive or obstructive pattern, no study investigating the effects of inspiratory muscle training has been found in the literature. To our knowledge, this study is the first to examine the effects of inspiratory muscle training on respiratory function in individuals with SUD. In our study, it was assumed that inspiratory muscle training could be a simple and inexpensive technique to improve dyspnea, respiratory functions, respiratory muscle strength, cough capacity, and exercise capacity in individuals with SUD, reduce substance cravings, increase quality of life, and reduce depression and anxiety, thus making it suitable for routine clinical use. The aim was to examine the effectiveness of inspiratory muscle training on dyspnea, respiratory functions, respiratory muscle strength, functional exercise capacity, substance craving, anxiety, depression, and quality of life in individuals with substance use disorders.
Interventions
- Other Inspiratory muscle training programme
In addition to their standard treatment, individuals in the inspiratory muscle training group will participate in inspiratory muscle training for a total of 30 minutes with a threshold loading device (POWERbreathe®) for 15 minutes twice a day, 5 days a week for 4 weeks under the supervision of a physiotherapist. - Other control group
Individuals in the control group will continue their standard treatment. No changes will be made in the medical treatments (type, dosage and frequency) of the individuals in both groups (the inspiratory muscle training group and the control group) during the study.
