{'armGroupLabels': ['Visual Biofeedback Group'], 'description': 'Supervised effortful saliva swallow exercise delivered by a speech-language therapist. Each session included five sets with 2-minute rest intervals: 16 swallows per set at 15-second intervals in weeks 1-2, and 20 swallows per set at 10-second intervals in weeks 3-4. The IOPI bulb was placed at the posterior tongue. The IOPI was operated in Target Mode at 80% of baseline maximum posterior tongue pressure, and participants received real-time visual feedback when the target was reached. Correct swallow execution was confirmed by observation of hyolaryngeal movement.', 'name': 'Effortful swallow exercise with visual biofeedback', 'type': 'BEHAVIORAL'} (protocolSection.armsInterventionsModule.interventions[])
{'armGroupLabels': ['Non-biofeedback Group'], 'description': 'Identical supervised effortful saliva swallow exercise protocol (same frequency, duration, sets, repetitions, intervals, and posterior tongue bulb placement). The IOPI was operated in Peak Mode, and the display was visible only to the therapist. Participants received standardized verbal instructions without visual feedback. Correct swallow execution was confirmed by observation of hyolaryngeal movement.', 'name': 'Effortful swallow exercise without visual biofeedback', 'type': 'BEHAVIORAL'} (protocolSection.armsInterventionsModule.interventions[])
