Brief summary

In this clinical trial, the investigators are seeking to learn if a course of voice therapy, including neck massage, stretches and pain science education in addition to voice exercise and scar massage will effectively treatment patient complaints of swallowing or voice changes after total thyroidectomy as compared to voice exercise and scar massage alone. The main questions it aims to answer are: Will neck massage, stretches and pain science education reduce patient complaints of swallowing changes after total thyroidectomy? Will neck massage, stretches and pain science education reduce patient complaints of voice changes after total thyroidectomy? Will neck massage, stretches and pain science education reduce patient complaints of scar tethering and quality changes after total thyroidectomy? Will neck massage, stretches and pain science education improve quality of life after total thyroidectomy? Participants will: Participate in 4 visits with the participant's endocrine/laryngology surgeon. One prior and 3 after surgery for endoscopic evaluation and tests. Participate in 5 Speech-Language Pathology Sessions for intervention exercises and tests. One prior and 4 after surgery. Complete a journal of the participant's Home Exercise Practice

Interventions

BEHAVIORALAnterior Neck Manual Therapy

Manual massage applied to the anterior neck, including hyolaryngeal elevators, depressors, sternocleidomastoid.

BEHAVIORALPain Neuroscience Education

Description of how the pain system works from a neurobiological level, discussing the biopsychosocial model that influences pain.

BEHAVIORALNeck Stretches

Bilateral cervical side bending, cervical extension and bilateral rotational neck stretches held for 20 seconds x3.

BEHAVIORALScar massage

Digital manipulation of the scar itself in circles.

BEHAVIORALVoice Exercises

Stemple Voice Exercises

BEHAVIORALPlacebo Anterior Neck Manual Therapy

Will apply extremely light manual contact to the anterior neck, including hyolaryngeal elevators, depressors, sternocleidomastoid.

BEHAVIORALPlacebo Pain Neuroscience Education

Will discuss how pain will as a result of the surgical intervention.

BEHAVIORALPlacebo Neck Stretches

Will ask patient to look down as a neck stretch held for 20 seconds x3.

Intervention model description

This is meant to be a parallel study. However, The Speech Language Pathologists will not be blinded as the Speech Pathologists are providing each regimen. If a participant in either group requires more intensive sessions or a differing regimen given the severity of complaints, the participants will receive it as per the recommendation of the Speech-Language Pathologist so as not to unblind the PI. An intent to treat analysis will be performed to accurately describe the data in the case of crossover and/or dropout.

Inclusion criteria

* The study population consists of individuals with malignant or benign thyroid disease scheduled to undergo total thyroidectomy * native speakers of English * All patients will be greater than or equal to 18 years of age

Exclusion criteria

* Participants will be excluded if they have completed voice therapy prior * are current smokers * have organic vocal fold pathology or clear mucosal changes to the vocal folds that can affect vibration (e.g., vocal fold scar, polyp, or nodules), * pre-existing unilateral or bilateral vocal fold paralysis * have had prior surgical neck or chest history including central or lateral neck dissection * pre- or post-operative abscess or inflammation * have a history of radiation, chronic cervical pain or cervicalgia, abnormal baseline swallowing * have underlying and, or plan to change supplemental hormones * greater than 10% otherwise unexplained weight loss * had a recent aspiration pneumonia * history of esophageal interventions or surgeries

Design outcomes

Primary

MeasureTime frameDescription
Acoustic measures of voice clarityBaseline, 1 yearAcoustic measurement of relative Cepstral Peak Prominence (dB) in a speaking voice sample.
Acoustic measures of speaking voice pitchBaseline, 1 yearAcoustic measurement of average fundamental speaking pitch in Hertz before and after surgery.
Acoustic measures of speaking voice quality subjectivelyBaseline, 1 yearClinicians will rate each patient's voice as having or not having each of the following perceptual qualities: Grade, Roughness, Asthenia, Breathiness, Strain. The scale is as follows: 0 (no perceptual quality) to 3 (severe perceptual quality).
Swallowing Quality of Life as assessed by the Eating Assessment Tool - 10Baseline, 1 yearPatients will rate themselves from a 0 - 4 (0: no problem to 4: Severe Problem) on 10 items within the Eating Assessment Tool - 10
Laryngeal sensationBaseline, 1 yearUsing a visual analogue scale of pain - from 0: no pain, to 10: worst pain. Patients will rate their pain.
Scar Tethering DistanceBaseline, 1 yearDistance in centimeters will be measured between the hyoid bone and scar with swallowing.
Scar Quality as assessed by The Patient and Observer Scar Assessment ScaleBaseline, 1 yearThe Patient and Observer Scar Assessment Scale will be used to measure from 0: normal skin, to 10: worst scar imaginable.
Voice Quality of Life as measures by the Voice Related Quality of Life - 10Baseline, 1 yearQuality of life measures: On a raw scale from 10 - 50 : 10 being no impact on quality of life, and 50 being the greatest impact on quality of life, participants will rate themselves.

Secondary

MeasureTime frameDescription
Adverse Effects in the Experimental GroupBaseline, 1 yearWill document the total number of adverse effects in the experimental group.
