Myofascial Release Effects in Teachers' Posture, Muscle Tension and Voice Quality: A Randomized Controlled Trial.

Objective: Myofascial release (MFR) comprises a set of manual therapeutic techniques applied to many conditions, but specific evidence concerning its effects on body posture, muscle tension and voice has been lacking. Thus, the aim of this study was to verify the effects of MFR in teachers' posture, muscular tension and voice quality.

Study Design: Randomized controlled trial - crossover.

Associations Between Teachers' Autonomic Dysfunction and Voice Complaints.

Objective: This investigation aimed to verify if there were any differences in autonomic nervous system function and voice parameters of teachers with and without voice complaints.

Study Design: Cross-sectional study.

Methods: The Questionnaire of Autonomic Dysfunction was answered by 24 teachers, 6 males, and 18 females, whose heart rate variability was also assessed.

Associations between Teachers' Posture, Muscle Tension and Voice Complaints.

Objective: The interaction between muscle tension, posture, and vocal use is very complex as clinical research suggests that abnormal laryngeal posture can be associated with muscle adaptive changes, although specific evidence concerning body posture and voice disorders has been lacking. Thus, the aim of this study was to verify if there were differences in posture, muscle tension and voice between teachers with and without voice complaints.

Study Design: Cross-sectional study.

Acupuncture can be beneficial for exercise-induced muscle soreness: A randomised controlled trial.

Introduction: Strenuous physical exercise may cause acute muscle soreness (AMS), which occurs directly after exercise, as well as delayed onset muscle soreness (DOMS), which occurs about 24 h after exercise. Studies of acupuncture's effect on DOMS have had contradictory results, whereas its effect on AMS has not been extensively studied. The main goal of this study was to evaluate acupuncture's effects on AMS and DOMS and on the prevention of DOMS.

Associations Between Autonomic Nervous System Function, Voice, and Dysphonia: A Systematic Review.

Objective: The study aimed to verify the relation between autonomic nervous system (ANS) dysfunctions, voice, and dysphonia.

Study Design: The study is a systematic review.

Methods: According to the PRISMA flowchart, a search on Pubmed/Medline, SciELO, RCAAP, LILACS, Cochrane Library, PEDro, and Isi Web of Knowledge was performed up to April 2019 using the following key words: autonomic nervous system and voice or dysphonia.
