Investigation of the Effects of Diaphragm Exercises in Children With Cerebral Palsy

The aim of this study is to examine the effects of diaphragmatic myofascial relaxation exercise and diaphragmatic breathing exercises added to the conventional physiotherapy and rehabilitation program in children with diplegic cerebral palsy (CP), primarily on MIP, MEP, and secondarily on thoracic cage mobility, pulmonary functions and sitting ability.

Study Overview

• Status: Completed
• Conditions: Cerebral Palsy Spastic Diplegia
• Intervention / Treatment: Other: Diaphragmatic exercises; Other: conventional physiotherapy

Detailed Description

This research is a randomized controlled trial. Volunteers diagnosed with cerebral palsy who applied to Marmara University Pendik Training and Research Hospital will participate in the research. A voluntary consent form will be obtained from the participants at the beginning of the study. Demographic and clinical information form will be filled for each patient at the beginning of the study before clinical evaluations. Demographic and clinical information form; Age, gender, height, weight, body mass index (BMI), how many weeks were born, birth weight, drug use, disease history, number of siblings, neonatal intensive care hospitalization history, education level of parents will be questioned. The Gross Motor Functional Classification System (KMFSS) will be used to determine the functionality levels of the volunteers who will participate in the study. The following tests will be applied to all of the volunteers who will participate in our study before and after the intervention:

Respiratory Muscle Strength Measurement Thoracic Cage Mobility Assessment Pulmonary Function Tests Gross Motor Functional Measurement (part B) Children meeting the inclusion criteria will be randomly assigned to two groups. The control and research groups will receive an individualized conventional rehabilitation program for 45 minutes, 2 days a week for 8 weeks. In addition to conventional rehabilitation, manual diaphragmatic relaxation exercises and diaphragmatic breathing exercises will be applied to the children in the research group two days a week.

After 8 weeks of intervention and control group applications, the evaluations made at the beginning of the intervention will be repeated. The evaluations of the two groups will be compared statistically and the results will be interpreted.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Research Group; Diplegic Cerebral Palsy	Other: Diaphragmatic exercises; Diaphragm exercises will be applied to the research group in addition to conventional rehabilitation.The content of the individualized conventional rehabilitation program consists of passive stretching exercises, strengthening exercises to antagonists of spastic muscles and exercises aimed at improving weight transfer, balance and correction reactions, and postural control. In addition to conventional rehabilitation, manual diaphragmatic relaxation exercises and diaphragmatic breathing exercises will be applied to the children in the research group two days a week.
Active Comparator: Control Group; Diplegic Cerebral Palsy	Other: conventional physiotherapy; The control group will only be taken to the conventional rehabilitation program. e content of the individualized conventional rehabilitation program consists of passive stretching exercises, strengthening exercises to antagonists of spastic muscles and exercises aimed at improving weight transfer, balance and correction reactions, and postural control.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Respiratory Muscle Strength Measurement (Maximum inspiratory pressure)	It will be used as the primary outcome measure in the study. In our study, respiratory muscle strength will be measured with a portable intraoral pressure measuring device (MicroRPM) Maximum static inspiratory pressure (MIP) will be measured at residual volume after maximum expiration. Measurements will be made twice in a sitting position with verbal encouragement and using a nose clip. The highest value obtained, with no more than 10% or 10cmH2O difference between the two measured values, will be used for analysis	8 weeks
Respiratory Muscle Strength Measurement (Maximum Expiratory Pressure)	It will be used as the primary outcome measure in the study. In our study, respiratory muscle strength will be measured with a portable intraoral pressure measuring device (MicroRPM) Maximum static expiratory pressure (MEP) will be measured at maximum post-inspiratory total lung capacity. Measurements will be made twice in a sitting position with verbal encouragement and using a nose clip. The highest value obtained, with no more than 10% or 10 cmH2O difference between the two measured values, will be used for analysis	8 weeks
Thoracic Cage Mobility Assessment	Chest circumference measurements will be used to determine respiratory type. Measurements will be recorded in centimeters, using a tape measure, in an upright sitting position, from the axillary, epigastric and subcostal regions, the difference between neutral, deep inspiration and deep expiration	8 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pulmonary Function Tests (PFT)	Pulmonary function tests will be performed with a spirometer device in the evaluation of pulmonary capacity. Pulmonary function tests are maneuvers applied to measure lung functions using standard devices. In this thesis, forced vital capacity (FVC), forced vital volume in one second (FEV1), FEV1/FVC and peak expiratory flow (PEF) values will be examined with pulmonary function tests.	8 weeks
Gross Motor Functional Measurement (Part B)	Sitting skill will be evaluated with the sub-section B of the Gross Motor Function Measure (GMFM) test. Sitting, which is part B, consists of 20 items. The gross motor functions in these items are evaluated according to the degree of achievement of the function. Scoring is done on a Likert scale between 0 and 3 points. A score of 0 indicates that the activity could not be started at all, and 3 indicates that 90-100% of it can be done.	8 weeks
