Effects of CTAR and PNF Exercises on Swallowing in Multiple Sclerosis (CTAR-PNF-MS)
Effects of Proprioceptive Neuromuscular Facilitation and Chin Tuck Against Resistance Exercises on Swallowing Function in Patients With Multiple Sclerosis and Dysphagia: A Randomized Controlled Trial
This study compares two exercise programs for people with multiple sclerosis (MS) who have trouble swallowing. One group did chin exercises against resistance (CTAR), and the other group did neck exercises based on a technique called proprioceptive neuromuscular facilitation (PNF). Both groups also received a sensory technique to help trigger swallowing.
The study tested whether these exercises could improve swallowing ability, swallowing speed, and quality of life related to eating and drinking. Participants were randomly assigned to one of the two exercise groups and were treated for 8 weeks, three times per week. Swallowing was assessed before and after treatment using validated questionnaires and a water-swallow test.

상세 설명
Multiple sclerosis (MS) is a chronic, immune-mediated disease of the central nervous system that frequently causes dysphagia (swallowing difficulty), which can lead to aspiration pneumonia and reduced quality of life. Exercise-based interventions targeting the suprahyoid and infrahyoid muscles are commonly used in dysphagia rehabilitation, but comparative evidence between Chin Tuck Against Resistance (CTAR) exercises and cervical Proprioceptive Neuromuscular Facilitation (PNF) exercises in MS patients is lacking.
This randomized, controlled, single-blind (outcome assessor blinded) trial enrolled adults aged 18-65 with a confirmed diagnosis of MS (per 2017 McDonald criteria), a DYMUS score ≥1, and no relapse in the preceding 6 months. Participants were allocated 1:1 to either the CTAR group or the PNF group using a computer-generated randomization sequence (minimization method, balanced for sex and disease course), with allocation concealed via sequentially numbered, sealed, opaque envelopes.
Both groups received Thermal-Tactile Stimulation (TTS) as a shared baseline treatment. The CTAR group performed isometric chin-tuck exercises against a resistance ball (2-3 sets x 8-12 repetitions per session). The PNF group performed cervical combined isotonic contraction techniques using diagonal movement patterns (30 repetitions per session). Both groups trained 3 sessions per week for 8 weeks (24 sessions total), with total session duration equalized between groups (approximately 30 minutes, including rest periods and TTS).
The primary outcome was change in DYMUS total score from baseline to week 8. Secondary outcomes included the Eating Assessment Tool (EAT-10), 100 mL Water Swallow Test parameters (swallowing duration, speed, and volume), the Functional Oral Intake Scale (FOIS), and the Swallowing Quality of Life Questionnaire (SWAL-QOL). Adverse events related to exercise (pain, fatigue, choking sensation) were systematically monitored at each session

실험적: CTAR Group
Participants received Chin Tuck Against Resistance (CTAR) exercises combined with thermal-tactile stimulation, 3 sessions/week for 8 weeks.
|
Participants performed isometric chin-tuck exercises against resistance using a ball positioned under the chin.
Each session consisted of 2-3 sets of 8-12 repetitions, with each isometric contraction sustained for 5-10 seconds and 30-60 seconds of rest between sets.
Sessions were conducted 3 times per week for 8 weeks (24 sessions total), supervised by a physiotherapist certified in swallowing rehabilitation.

실험적: PNF Group
Participants received cervical Proprioceptive Neuromuscular Facilitation (PNF) exercises combined with thermal-tactile stimulation, 3 sessions/week for 8 weeks.
|
Participants received cervical proprioceptive neuromuscular facilitation using a combined isotonic contraction technique with diagonal movement patterns.
Each repetition involved movement from an extension-left rotation position to a flexion-right rotation position against manual resistance, followed by a 6-second isometric hold and controlled eccentric return; the pattern was also performed in reverse diagonal direction.
A total of 30 repetitions were completed per session without rest between repetitions.
Sessions were conducted 3 times per week for 8 weeks (24 sessions total), supervised by a physiotherapist certified in swallowing

Change in DYMUS (Dysphagia in Multiple Sclerosis Questionnaire) Total Score
기간: Baseline and week 8 (post-treatment)
|
The DYMUS is a 10-item self-report questionnaire assessing oropharyngeal dysphagia in multiple sclerosis patients, scored 0 (no) to 1 (yes) per item, yielding a total score range of 0-10.
Higher scores indicate greater dysphagia severity.
A score ≥3 indicates severe swallowing difficulty.
