Summary: Objectives/Hypothesis. This study aimed at reporting on an intervention for optimizing postural
alignment and voice parameters.
Study Design. Case report.
Q7 Methods. Postural alignment and a clinical examination were performed, and several voice parameters were
investigated before, during, and after an individual rehabilitation program aimed at optimizing joint mobility, muscular
stability, and posture. This program was given to a 26-year-old female classical singing student.
Results. After a nine-session intervention (4 months), postural alignment was improved. The patient showed a good
breath support and was able to maintain the lateral dimensions of the thorax, except for the high tones. Furthermore,
she had a normalized cervical and scapulothoracic stability.At the last session, she had a lack of relaxation of the masseter
muscle while singing. The vocal dynamic and pitch range were extended with smoother curves connecting the measuring
points of the maximal and minimal vocal intensity, measured by means of the voice range profile.
Conclusions. Results show that, in this student singer, postural alignment could be changed within 4 months and that
it could influence some voice parameters. Further research in larger samples is necessary to see whether these findings
can be generalized to other singers.
