简要总结
This multi-site trial will follow a cohort of Veterans with dysphagia for 8 weeks as they undergo clinically guided oropharyngeal exercises with oropharyngeal strengthening as the primary goal. Veterans with dysphagia will be assessed at three time points: baseline, 4 weeks after treatment initiation, and 8 weeks after treatment initiation. A non-dysphagic Veteran control group will also undergo data collection at parallel time points, without completion of a treatment paradigm. The investigators will then compare patients to non-dysphagic controls using manometry, videofluoroscopy, diet assessment, functional reserve tests, and patient-reported outcome measures.
The investigators aim to 1) quantify change in pressure measures of swallowing function resulting from dysphagia treatment; 2) determine which combination of standard of care and/or pressure-based metrics best track with outcome measures; and 3) develop multimodal prognostic algorithms that predict treatment success. This research will establish a precise outcome measurement paradigm suitable for dysphagia clinical care and research, thus improving clinical confidence and paving the way for a personalized medicine approach for dysphagia rehabilitation in Veterans.
详细描述
This multi-center trial will follow a cohort of Veterans with dysphagia for 8 weeks as they undergo clinically guided oropharyngeal exercises with oropharyngeal strengthening as the primary goal. Veterans with dysphagia will be assessed at three time points: baseline, 6-4 weeks post-treatment, and 8 weeks post-treatment. A non-dysphagic Veteran control group (n=50) will also undergo data collection at parallel time points, without completion of a treatment paradigm. The investigators will then compare patients to nondysphagic controls using pHRM, videofluoroscopy, diet assessment, functional reserve tests, and patient reported outcome measures. The investigators aim to 1) quantify change in pHRM measures of swallowing function resulting from dysphagia treatment; 2) determine which combination of standard of care and/or pHRM-based metrics best track with patient-reported outcome measures; and 3) develop multimodal prognostic algorithms that predict treatment success. This research will establish a precise outcome measurement paradigm suitable for dysphagia clinical care and research, thus improving clinical confidence and paving the way for a personalized medicine approach for dysphagia rehabilitation in Veterans.

结局指标
主要结局
pHRM pressure change
时间窗: Baseline, 4 weeks, and 8 weeks
Will assess the change in pressure by pharyngeal high resolution manometry over the time frame The primary measure of interest is Integral Pressure during the 10 mL swallow at the tongue base Range is From: 0 mmHg\*sec, no pressure recorded to up to 250 mmHg\*sec., very high pressures recorded, normal range is age and sex dependent Range (114+/-50 to167 +/-80) Positive change would be a movement toward normal range of pressure. This metric is measured automatically in both Software systems used to evaluate pharyngeal pressure (WiscMano and Swallow gateway)
Swallowing clinical and fluoroscopic change
时间窗: Baseline, 4 weeks, and 8 weeks
Will assess the change in fluoroscopy and clinical assessments over the time frame The primary tool of measurement is the combined score of the MBSImP this is a 17 item standardized tool to measure impairment of swallow identified using contrast barium swallows. We will use the composite pharyngeal score which ranges from 0 to 3, the higher the score the more abnormal the swallow function, Normal swallows will score 5 or less and severe dysphagia will score 9 or higher. Movement toward 0 is a positive or improved swallow function, movement toward 23 is negative or worsening swallow function
Patient reported outcome changes
时间窗: Baseline, 4 weeks, and 8 weeks
Sydney swallowing questionnaire (SSQ) The SSQ is a patient reported symptom scale with 17 questions, each scaled from 0+ no dysfunction to 100 equal extreme dysfunction using a 100mm visual analogue scale with 0 and 100 as anchors. the total score can be recorded for 0 to 1700, Normal swallowers will average 40 with a range of 200 to 0, Dysphagia patients average 800 with a range of 150 to 1600. Movement toward 0 will be considered an improvement, movement toward 1700 worsening in swallowing ability preserved by the patient.
