Inspiratory Muscle Training in Cerebral Palsy Patients
- Conditions
- Respiratory Insufficiency
- Interventions
- Device: Inspiratory muscle training
- Registration Number
- NCT04915170
- Lead Sponsor
- University of Salamanca
- Brief Summary
To evaluate the effectiveness of two protocols of inspiratory muscle training (IMT) in cerebral palsy patients to improve respiratory strength and spirometric parameters. Low-intensity vs high-intensity resistance training programs. Evaluations: Determination of the maximum inspiratory pressure (MIP) and the maximum expiratory pressure (MEP); spirometry - peak expiratory flow (PEF), forced expiratory volume in first second (FEV1) and clinical evaluations. The participants will be evaluated at the beginning and end of the intervention period. Intervention: There are two groups of patients, one works with low loads (20% MIP) and another with high loads (40% MIP). They train 5 days/week 10 cycles lasting 1 minute. There is a rest of 1 minute between each cycle.
- Detailed Description
The study was a controlled, randomised, double-blind trial and with allocation concealment. The study protocol was approved by the Bioethics Committee of the University of Salamanca (number of registry 678, 6th October 2021).
Participants:
Institutionalized people with cerebral palsy between 35 and 64 years were included, they were all members of ASPACE Salamanca.
All patients will be asked to carry out the 5-day weekly program, and a recording sheet will be provided to each participant so they will can record the time of each daily respiratory training session. All participants signed an informed consent form.
The patients will be assigned to the two groups randomly. The main researcher doesn´t meet any of the participants until the initial assessment will be carried out.
Intervention:
"High-intensity group". The device incorporates a unidirectional valve independent of flow to guarantee constant resistance and includes a specific pressure setting (in cm H2O).
The intensity of the device will be 40% of MIP. The protocol includes 10 cycles lasting 1 minute. The participants rest for 1 minute between each cycle. In total, the protocol includes 10 minutes of daily respiratory training. The patients will be instructed to inhale with enough force to reach the opening of the valve.
"Low-intensity group".The device incorporates a unidirectional valve independent of flow to guarantee constant resistance and includes a specific pressure setting (in cm H2O).
The intensity of the device will be 20% of MIP. The protocol includes 10 cycles lasting 1 minute. The participants rest for 1 minute between each cycle. In total, the protocol includes 10 minutes of daily respiratory training. The patients will be instructed to inhale with enough force to reach the opening of the valve.

Group Intervention Description High intensity group Inspiratory muscle training Intervention is administrated with an inspiratory muscle trainer (IMT). High intensity group: 10 cycles, 1 minute each one, 40% MIP with IMT. 1 minute to rest between cycles. Low intensity group Inspiratory muscle training Intervention is administrated with an inspiratory muscle trainer (IMT). Low intensity group: 10 cycles, 1 minute each one, 20% MIP with IMT. 1 minute to rest between cycles.
- Primary Outcome Measures
Name Time Method Maximal inspiratory pressure 2 minutes The evaluation is performed using a pressure transducer, Elka 15, which obtainer each measurement in millibar and converted it into the reference unit of centimeter of water (cm H2O) (1 mbar = 1.01973 cm H2O), following the rules of the American Thoracic Society/European Respiratory Society (ATS / ERS). The procedure was repeated until 3 values were obtained with a difference of less than 5%, and the highest value was used for the analysis.

- Secondary Outcome Measures
Name Time Method Pulmonary flow 1 minute The evaluation is performed collecting peak expiratory flow (PEF). It was measured using the peak flow device (Asma-1, Vitalograph Ltd, Buckingham, England)
Pulmonary volume 1 minute The evaluation is performed collecting forced expiratory volume in 1 second (FEV1). It was measured using the peak flow device (Asma-1, Vitalograph Ltd, Buckingham, England)
