Summary

Individuals who were diagnosed with reduction disc displacement by Research Diagnostic criteria for Temporomandibular Disorder (TMD / RDC) were included in the study. Proprioceptive neuromuscular facilitation exercises were performed for 30 minutes using neck jaw and tongue patterns with rhythmic stabilization (RS) and combination of isotonics (CI) techniques by physiotherapist. Maximal mouth openings were measured with caliper, pain intensities were measured with visual analogue scale and pressure pain thresholds with hand algometer.

Detailed description

TMD patients who are diagnosed by TMD/RDC are firstly assessed by physiotherapist for maximal mouth opening(MMO), pain intensity and pressure pain threshold. Then they will taught exercises with rhythmic initiation which includes repetation of the patern and 15 repetitions are applied as warm-up period. Proprioceptive neuromuscular facilitation (PNF) exercises are performed in the neck and jaw patterns with rhythmic stabilization (RS) and combination of isotonics (CI) techniques. In the neck, right rotation-right lateral flexion, left rotation-left lateral flexion pattern, and the opening and closing pattern according to the working mechanics of the masseter and temporal muscle in the chin, RS and CI techniques are used. By providing maximum resistance in accordance with the needs of each individual, the RS protocol consist of isometric contractions that would not involve changing movements for 10 seconds. The combination of isotonics technique include combined concentric, isometric, and eccentric contraction of the agonist muscle for 5 seconds of each contraction without rest. CI exercises consist of 15 repetitions per set. A 30-second rest given between sets to include recovery. After exercises immediate MMO, pain intensity and pain treshold assessment will be applied.
