Objective: Research is designed to determine speech respiratory measures in spastic cerebral palsied children versus normal ones, to be used as an applicable tool in speech therapy plans. 

Materials & Methods: Via a comparative cross-sectional study (case – control), and through a directive goal oriented sampling in case and convenience approach for controls twenty spastic cerebral palsied and twenty control ones with age (5-12 years old) and sex (F=20 M=20) were matched and identified. All possible inclusion and exclusion criteria were considered by thorough past medical, clinical and para clinical such as chest X-ray and Complete Blood Counts reviews to rule out any possible pulmonary and/or systemic disorders. Their speech respiratory indices were determined by Respirometer (ST 1-dysphonia), made and normalized by Glasgow University. Obtained data were analyzed by independent T test. Results: There were significant differences between cases and control groups for "mean tidal volume", "phonatory volume" and "vital capacity" at =0/05 values and these values in patients were less (34%) than normal children (P<0/001).

Conclusion: Measures obtained are highly crucial for speech therapist in any speech therapy primary rehabilitative plans for spactic cerebral palsied children.
