P02.180. Arts speech therapy influences heart rate variability indices

Methods Measurement in 24 adults comprised 8 minutes pre-baseline, 5 minutes recitation, 5 minutes recovery, 5 minutes recitation, and 20 minutes post-baseline. Measurements were performed for 3 different AST tasks [recitation of alliterative (RA), hexameter (RH), and prose (RP) verses] and a control task [mental arithmetic (MA) with voicing of the result] in a randomized crossover design. HRV was determined using a Medilog AR12 holter ECG. Multifractality of HRV was determined using the multifractal detrending moving average method. Statistical analysis was applied to the difference between pre-baseline, 2 recitation and 5 baseline periods. The four tasks were tested separately; p≤0.05 was considered significant.
