Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
1. Does TPRT increase the electrical activity of the suprahyoid muscles (a key muscle group for swallowing) more than standard care?
2. Does TPRT reduce scores on the Penetration-Aspiration Scale (PAS), a measure of swallowing safety, more than standard care?
3. Researchers will compare the TPRT intervention group to the active control group to see if the simple, home-based TPRT exercise is as effective or more effective than standard hospital-based therapies.
Participants in the intervention group will:
Perform the TPRT exercise (pressing their tongue against the palate) for 30 repetitions, 5 times a week, for 8 weeks at home.
Be supported by a caregiver and use a video guide and logbook.
Participants in the control group will:
Receive standard hospital-based therapy twice a week, which may include Neuromuscular Electrical Stimulation (NMES) or biofeedback.
Perform unsupervised Chin Tuck Against Resistance (CTAR) exercises at home.
All participants will also receive education on safe swallowing techniques.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Journal \& Type: This is a manuscript for publication, presenting the results of a single-blind, randomized controlled trial (RCT).
Authors: The team is multi-disciplinary, consisting of experts in Internal Medicine, Physical Medicine and Rehabilitation (PM\&R), and Radiology from Cipto Mangunkusumo Hospital/University of Indonesia, and a collaborator from Germany.
Background \& Rationale:
Problem: Oropharyngeal dysphagia (difficulty swallowing) is a very common and serious problem in the elderly, leading to malnutrition, pneumonia from aspiration, and increased death rates.
Current Solutions: Existing therapies (like Shaker exercises or electrical stimulation) can be difficult for frail elderly patients to perform or require clinic visits.
Proposed Solution: Tongue-to-Palate Resistance Training (TPRT) is a simple, home-based exercise that could strengthen tongue and throat muscles, potentially improving swallowing. Preliminary studies showed it increases muscle activity, but robust evidence in geriatric patients was needed.
Objective: To determine if an 8-week home-based TPRT program is effective at improving swallowing muscle activity (measured by electromyography/sEMG) and swallowing safety (measured by the Penetration-Aspiration Scale on videofluoroscopy) in elderly dysphagia patients.
Methods:
Design: Single-blind Randomized Controlled Trial (RCT).
Participants: 20 elderly patients (\>60 years) with confirmed oropharyngeal dysphagia. They had to have low baseline muscle activity and an available caregiver.
Intervention Group (n=9): Performed home-based TPRT (30 reps, 5x/week for 8 weeks) with video guidance and logbook monitoring.
Control Group (n=8): Received standard care, which included clinic-based Neuromuscular Electrical Stimulation (NMES) or biofeedback twice a week plus unsupervised home exercises (Chin Tuck Against Resistance).
Measurements:
Primary Outcome 1: Suprahyoid Muscle Activity. Measured using surface electromyography (sEMG) at baseline, 4 weeks, and 8 weeks.
Primary Outcome 2: Swallowing Safety. Measured using the Penetration-Aspiration Scale (PAS) via Videofluoroscopic Swallowing Study (VFSS) at baseline and 8 weeks.
Secondary Outcomes: Hyoid bone movement (crucial for swallowing) and Pharyngeal Transit Time (PTT) were also measured from the VFSS.
Analysis: Used advanced statistical tests (Repeated Measures ANOVA, Wilcoxon tests) to compare changes within and between groups over time.

Study Groups

Tongue-to-Palate Resistance Training (TPRT)
Participants in this arm performed a home-based Tongue-to-Palate Resistance Training (TPRT) program. The intervention consisted of pressing the tongue against the palate for 30 repetitions per session, five sessions per week, for a total of eight weeks. Participants were provided with video guidance and a logbook to record adherence, and were supported by a caregiver. This was a simple, device-free exercise regimen designed to strengthen the oropharyngeal and suprahyoid musculature.
Tongue-to-Palate Resistance Training
The Tongue-to-Palate Resistance Training (TPRT) is a home-based, device-free exercise program. Participants were instructed to press their tongue firmly against their hard palate and hold the contraction. The protocol consisted of 30 repetitions per session, performed five days a week for a duration of eight weeks. Adherence was supported through instructional videos, a caregiver, and a training logbook. The goal of the intervention is to strengthen the intrinsic and extrinsic tongue muscles and the suprahyoid muscle group to improve swallowing function.
Standard Dysphagia Therapy
Participants in this arm received the standard of care for oropharyngeal dysphagia. This included supervised, hospital-based sessions twice a week consisting of either Neuromuscular Electrical Stimulation (NMES) applied to the submental region or biofeedback swallowing therapy. Additionally, they were instructed to perform unsupervised Chin Tuck Against Resistance (CTAR) exercises at home. This arm represents the conventional, multi-modal rehabilitation approach against which the experimental TPRT intervention was compared.
Standard Dysphagia Therapy
The active comparator consists of a conventional, multi-modal standard of care for oropharyngeal dysphagia. It includes in-clinic sessions twice a week featuring either Neuromuscular Electrical Stimulation (NMES), where electrodes are placed in the submental region to stimulate the swallowing muscles, or biofeedback swallowing therapy. Additionally, participants perform unsupervised Chin Tuck Against Resistance (CTAR) exercises at home. This arm represents the established clinical rehabilitation approach against which the experimental TPRT intervention is compared
