Compare the effect of Mendelsohn maneuver, effortful swallow training, and the Shaker exercise on neurogenic dysphagia among stroke patients.
OtherTo achieve single blind in this trial, the participant is kept blinded to their group assignment (interventions and control groups) throughout the study. The data collector administers the assigned intervention (Mendelsohn maneuver, effortful swallow training, and the Shaker exercise ) without revealing the participant's group assignment. The researcher retains knowledge of group allocation to ensure Single blind. Interventions are randomized, and assess Effect of Mendelsohn maneuver, effortful swallow training, and the Shaker exercise on swallowing Ability without knowing the type of maneuvers received, ensuring that participants' expectations do not influence the results. These procedures reduce the influence of prior expectations and ensure an effective study.
