Figure 2From: Effects of seat surface inclination on respiration and speech production in children with spastic cerebral palsyComparison of respiration function in three positions of seat surface inclination. The asterisk indicates a significant difference between 15° of anterior inclination and 15° of posterior inclination (P < 0.05). (A) FVC, (B) FEV1, and (C) PEF represent forced vital capacity (liter (L)), forced expiratory volume in 1 s (L), and peak expiratory flow (L/second (L/s)). Error bars represent standard deviations (SD).Back to article page
