Efficacy of Kinesio taping on Mutational Falsetto: A Double Blind, Randomized, Sham-controlled Trial.

ABSTRACT

OBJECTIVES: This study aimed to assess the efficacy of Kinesio taping on male patients with mutational falsetto undergoing voice therapy. DESIGN: Double blind, randomized, sham-controlled clinical trial. PARTICIPANTS: Interviews were conducted with thirty seven mutational falsetto patients. Included 32 participants were randomized and divided into two groups. Two were dropped out due to irregular attendance, 30 participants were included in final analysis. INTERVENTIONS: The study group was treated with voice therapy and applications of three different therapeutic Kinesio taping techniques with seven Kinesio tapes four times over two weeks, and the control group was treated with voice therapy, and applied to sham Kinesio taping. OUTCOME MEASURES: The values of fundamental frequency, jitter, shimmer, noise-harmonic ratio, maximum phonation time, Voice Handicap Index-10 scores, and Grade-Roughness-Breathiness-Asthenia-Strain Scale scores were recorded at the baseline and after the two weeks. RESULTS: There were significant differences between the study group and the control group with respect to the values of fundamental frequency (P = 0.011), jitter (P = 0.041), shimmer (P = 0.036), noise-harmonic ratio (P = 0.003), maximum phonation time (P ≤ 0.001), Voice Handicap Index-10 scores (P = 0.036), and Grade-Roughness-Breathiness-Asthenia-Strain Scale scores (P = 0.007; P ≤ 0.021; P = 0.022; P = 0.002; P = 0.021, respectively) at the end of the study. CONCLUSIONS: The study demonstrated that Kinesio taping with voice therapy is an efficient and effective technique for treating mutational falsetto patients.
