Manual Therapy in Treating Fibrosis-Related Late Effect Dysphagia in Head and Neck Cancer Survivors

Not Applicable

Active, not recruiting

Brief Summary: This trial studies how well manual therapy works in treating fibrosis-related late effect dysphagia in head and neck cancer survivors. Manual therapy is the use of massage and stretching exercises to increase blood flow and muscle movement in the neck, throat, jaw, and mouth, which may help to improve swallowing ability and range of motion in participants who have had treatment for head and neck cancer.

Detailed Description: PRIMARY OBJECTIVES:

I. To determine the feasibility and safety of manual therapy for treatment of fibrosis-related dysphagia in head and neck cancer survivors.

SECONDARY OBJECTIVES:

I.To estimate effect size, dose-response (number of treatment sessions to normalized cervical range of motion), and durability of manual therapy for improving cervical range of motion in head and neck cancer survivors with fibrosis-related late dysphagia.

II. To examine functional outcomes after manual therapy in head and neck cancer survivors with fibrosis-related late effects and their association with change in dysphagia grade, cervical extension, and other cofactors.

OUTLINE:

Participants receive 10 manual therapy sessions performed by a speech pathologist during weeks 1-6. After completion of 6 weeks of therapy, participants perform manual therapy at home daily for 6 weeks.

Arm && Interventions

Group	Intervention	Description
Supportive Care (manual therapy)	Manual Therapy	Participants receive 10 manual therapy sessions performed by a speech pathologist during weeks 1-6. After completion of 6 weeks of therapy, participants perform manual therapy at home daily for 6 weeks.

Primary Outcome Measures

Name	Time	Method
Feasibility	Up to 12 weeks	Will be determined by completion rate. Completion rate will be defined by completion of the 6 week clinical manual therapy (MT) program without withdrawing and attending a minimum of 2 sessions and the post-treatment assessment. Session attendance will be monitored separately to assess adherence and fidelity. Will summarize fidelity and adherence to the standard MT protocol using quantitative and qualitative methods.
Incidence of adverse events	Up to 12 weeks	Will be graded according to Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Adverse events will be tabulated and will be monitored by the trial Data Safety Monitoring Board.

Secondary Outcome Measures

Name	Time	Method
Lingual and jaw range of motion (ROM)	Up to 12 weeks	Measured by Therabite ruler.
Symptom burden	Up to 12 weeks	Measured by the MD Anderson Symptom Inventory Head and Neck Cancer Module (MDASI-HN).
Lymphedema/fibrosis staging	Up to 12 weeks	Measured by the Common Terminology Criteria for Adverse Events and Head and Neck Lymphedema and Fibrosis Scale.
Performance status	Up to 12 weeks	Measured by the Performance Status Scale for Head and Neck Cancer Patients (PSS-HN).
Soft tissue fibrosis	Up to 12 weeks	Measured by magnetic resonance imaging.
Efficacy and durability of response	Up to 12 weeks; baseline, after manual therapy (6 weeks), and after home program wash-out period (6 weeks)	Will be determined by cervical range of motion (CROM). CROM for each anatomic plane measured by goniometer.
Swallowing function and physiology	Baseline to 6 weeks (after manual therapy)	Measured by videofluoroscopy using the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) and Computational Analysis of Swallowing Mechanics (CASM).
Swallowing-related quality of life	Up to 12 weeks	Measured by the MD Anderson Dysphagia Inventory (MDADI).
Improvement in tongue innervation on Electromyography (EMG) findings	Baseline to 6 weeks (after manual therapy)	Electromyography (EMG) scores are based on a 4-point denervation potentials grade with '0' being 'none' and '4' being 'full interference patterns of potentials'
