Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
All subjects will be informed about its purpose, manner of conducting and the possibility of resignation at any time during the research project. The respondents will give written consent to participate in the research. In addition, there will be an information meeting on the impact of respiratory muscle training on their muscle functions and on lung ventilation.
Study group (SG):
The research will cover women treated for breast cancer associated in the Wroclaw Femina Fenix Association, regularly participating in general gymnastics since the end of oncological treatment.
Control group (CG):
The control group will consist healthy women, never treated for neoplastic disease - students of the University of the Third Age at the University of Physical Education in Wroclaw, who also regularly participated in general improvement exercises.

Several women women (both SG and CG) will be involved in inspiratory muscle training using the Treshold device (Respironics Threshold IMT). At the beginning of the program (1 day of training), each group will conduct by physiotherapist an educational lecture (1 h) on the respiratory function and hygiene and breathing support techniques, and all participants of the inspiratory muscle training will additionally lecture combine with the presentation of the device and the training instructor Inspiratory muscle training will conduct 5 times a week, of which 4 sessions at home, and 1 under the supervision of a physiotherapist. Inspiratory muscle training lasted 8 weeks. Before starting the training program, instructional classes on the proper technique of performing exercises with the Threshold IMT apparatus will carry out, while maintaining the rules consistent with the technique of proper breathing.
Training take place in a standing position. After setting the individual resistance, the subjects place a nose clip and then tightly cover the mouthpiece with the mouth. The inspiratory phase will characterized by a quick, energetic, short and diaphragmatic breath. The exhale will slow, calm, and long and will to last until reaching the RV (residual volume), because every breath should start from that level. Each subject perform exercises alone on his personal training device. After the initial PImax assessment, an individual level of training load will set. The strength of the inspiratory muscles, in the first measurement, was expressed in kPa, and then it will be convert into cm H2O according to the formula 1 kPa = 10.2 cm H2O. This change allowed calculating the appropriate training load, using the Threshold IMT training device. In the first week, the training load will be 30% PImax, and each session last 5 minutes, twice a day. The value of the initial load will dictate by the safety conditions of conducting the training. In the following weeks, the load will be increased and the duration of exercise was extended during the day (60% PImax, 2x 15min). Each patient keep a participant diary in which recorded the dates and time of training. This diary is going to check by the physiotherapist once a week.

Other design features
The persons tested in this project will be divided into two groups. One will be women after treatment for breast cancer, the other one who did not have cancer. In both groups, according to randomization, there will be a division into people who will participate in inspiratory muscle training and those who will not practice.

Summary
Brief summary
The objective of this study is to assess the efficacy of and without inspiratory muscle training (IMT) on pulmonary function, inspiratory muscle strength in patients after breast cancer.
All examined women before and after training will be tested: maximal inspiratory and expiratory pressure (PImax and PEmax) values and lung function.
The first group will be women after treatment for breast cancer (about 48), the second group will be healthy women (n = 13). In each group, after randomized selection, half of the people will participate in the 8-week inspiratory muscle training on the Threshold device.
