Brief summary

This pilot study is a randomized controlled trial aimed at investigating the efficacy of protocolized conductive breathing exercises combined with regular air ventilation, in addition to standard care, on various aspects of health in school-aged children with cerebral palsy (CP). The primary objectives of the study include assessing the effects on pulmonary functions, quality of life (QoL), depression anxiety and stress (DAS) levels, eating-drinking ability (EDACS), and severity of drooling in this population. The study compares two groups of participants: one group undergoes protocolized conductive breathing exercises three times per day for five minutes, five days a week, while the other group receives only standard rehabilitation care. Evaluations include spirometry parameters ( forced vital capacity \[FVC\] forced expiratory volume in the first second \[FEV1\], FEV1/FVC ratio and peak expiratory flow \[PEF\]. Assessments are conducted at the beginning and end of the eight weeks intervention period, with additional evaluations after a 2.5-month washout period. The conductive breathing exercises, developed by Dr. András Pető, the founder of the conductive education system, consist of techniques such as diaphragmatic breathing, deep breathing, and playful forced expiration. Respiratory well-being is crucial, particularly in pediatric CP patients, as compromised pulmonary functions can significantly impact overall health. Despite this, there is currently a lack of established protocols and research regarding the efficacy of conductive breathing exercises in this specific population. Therefore, the this study seeks to address this gap by determining whether a structured regimen of conductive breathing exercises, when added to standard care, can lead to measurable improvements in respiratory health and QoL among school-aged children with CP.

Interventions

OTHERSeries of breathing exercises

During the intervention, participants perform respiratory exercises, including deep breathing, belly breathing, exhalation with vocalization, and forced exhalation. Each exercise is repeated five times, three times per day: twice in the morning and once in the afternoon. The exercises are conducted in a seated, corrected position, guided by rehabilitation specialists or special needs teachers who provide instructions and demonstrations. Teachers are provided with the exact protocol for the breathing exercises series. Each breathing exercise focuses on maintaining a specific rhythm, with inhalation lasting approximately 3-4 seconds, holding for 1-2 seconds, and exhalation for 5-6 seconds. Forced exhalation is facilitated using playful motivational tools such as windmills and balloon blowing. The protocol includes instructions for the breathing exercises in first-person singular. The entire session lasts approximately 5 minutes, resulting in a total of 15 minutes of training per day.

Masking description

The study employs double-blinded, whereby participants are unaware of their assigned treatment, and professionals are also unaware of whether they belong to the control or intervention group. The school-age children with CP in the study could only be randomised on the basis of class membership. The classes were separated, and the professionals involved were unaware of which group was assigned to the intervention or control. The professionals in the control group were provided with a breathing protocol that incorporated sham breathing tasks.

Intervention model description

The study compares two groups of participants: one group undergoes protocolized conductive breathing exercises three times per day for five minutes, five days a week, while the other group receives only standard rehabilitation care.

Secondary

MeasureTime frameDescription
Cerebral Palsy Quality of Lifemeasurement at 0 weeks, 8 weeks, 18 weeksThe CP QoL test measures changes in quality of life (QoL) across different domains, such as social and emotional well-being, acceptance, bodily pain, and functioning. The assessment is conducted at three time points: 0 weeks, 8 weeks, and 18 weeks. Scoring and Interpretation: Scale: Scores are recorded from 1 to 9, where 1 = Very unhappy and 9 = Very happy. Higher scores indicate better quality of life (QoL).
Severity and Frequency of Droolingmeasurement at 0 weeks, 8 weeks, 18 weeksThe severity and frequency of drooling will be assessed for changes.
