Effects of Core Strengthening Exercises for Treating TMD
Sponsor: Loyola University
Summary
Temporomandibular disorders (TMD) are commonly managed with non-invasive interventions such as manual therapy, therapeutic exercise, relaxation techniques, and patient education. Core strengthening (also known as abdominal strengthening) is a fundamental element of physical therapy that engages deep and superficial trunk musculature to enhance postural control and functional performance. Protocols such as the Shirley Sahrmann progression have demonstrated increased activation of key core stabilizing muscles. Emerging evidence suggests a potential relationship between core stability training and reductions in TMD-related pain, though improvements in functional outcomes remain inconclusive. Biomechanical links between the pelvic floor, spine, and temporomandibular joint further support the rationale for core-focused interventions. Nevertheless, few studies have isolated the effects of core strengthening on TMD symptomatology. This study seeks to determine whether the integration of core stability exercises into TMD management can reduce pain, improve function, and enhance quality of life.

Interventions
Experimental: Group 1: Core Strengthening
Participants perform Shirley Sahrmann core exercises (5 progressive levels maintaining neutral spine and deep core activation), possibly adding upper extremity movements. Standard TMD PT includes jaw exercises, manual therapy, soft tissue mobilization, neuromuscular re-education, and patient education. A home exercise program (\~20 min/day) is provided with printed and video instructions.
Group 2: Standard TMD PT
Participants receive standard TMD PT including jaw exercises (Rocabado 6x6), manual therapy for TMJ and cervical spine, soft tissue mobilization, neuromuscular re-education to improve jaw mechanics, and education on jaw positioning, diet/chewing modifications, and parafunctional habits. A home exercise program is provided as part of treatment.
