Swallowing disorders (dysphagia) are common and can incur a negative psychological impact in persons with multiple sclerosis. Mindfulness-Based Cognitive Therapy (MBCT) has the potential to treat dysphagia alongside associated mental health disorders. The purpose of this preliminary trial was to evaluate the efficacy of MBCT combined with diet modification (MBCT-DM) compared to diet modification (DM) alone on swallowing function in persons with multiple sclerosis and dysphagia.
The study design involved a preliminary randomized parallel two-arm trial. Forty-four participants with multiple sclerosis who had dysphagia symptoms were recruited and allocated to MBCT-DM or DM. The primary measure involved comparing the efficacy of the combined intervention (MBCT-DM) to DM alone on dysphagia outcomes. Secondary outcome measures included psychological symptoms, emotional regulation strategies, and level of mindfulness. Outcomes were assessed at baseline and immediately after treatment. We also explored recruitment potential and retention for the MBCT program.
Eighty-five percent of patients with suspected multiple sclerosis demonstrated interest. The first 44 eligible patients who signed consent were included. All completed at least six of the eight MBCT sessions. For the primary and secondary outcomes, all between-group differences favored the MBCT-DM intervention demonstrating decrease of dysphagia (η2 = 0.71) and psychological symptoms, and improvement of emotion regulation strategies, and mindfulness levels (η2 ranging from 0.69 to 0.77).
It is practical to deliver MBCT adjunct to diet modification for the treatment of dysphagia. Such treatment appears to confer physical and psychological benefits. A definitive RCT should be undertaken to confirm these preliminary data.
