    Mechanisms Through which Lordotic Posture Affects Learners with Cerebral Palsy’s Speech Production Ability in Nairobi City County, Kenya
    (Journal of Popular Education in Africa, 2025-03) Ochieng, Hillary Otieno; Ogogo, Joyce Achieng
    The purpose of the study was to investigate mechanisms through which Lordotic Posture affects learners with cerebral palsy’s speech production ability in Nairobi City County, Kenya. The research focused on how different postures influence muscle coordination, stiffness, and breathing, which in turn affect speech production, particularly in the mouth, neck, and facial muscles. The research was guided by the myoelectric-aerodynamic theory of voice production, identifying posture as the independent variable and speech production as the dependent variable. A cross-sectional research design was employed, incorporating a review of relevant literature on posture and speech production in children with Cerebral Palsy (CP). The research involved 296 children aged 2 to 10 years diagnosed with (CP) and four paramedics, totaling 300 participants. A combination of systematic and random sampling techniques was utilized to choose the study population. To ensure the accuracy and consistency of the findings, the study measured validity and reliability using Cronbach's alpha and Kappa coefficients. Data were analyzed using SPSS software and presented in tables, charts, and frequency distributions. Participation in the study was voluntary, and all participants were assured of confidentiality and anonymity. The findings indicated that specific postural conditions significantly impact speech production. The study identified that improper posture influences phonation by altering breathing patterns and vocal structure positioning. On the basis of these findings, some recommendations were provided.
