NCT03421028

Brief Summary

This study evaluates beneficial effects of biofeedback therapy in reducing pain and increased tension of muscles occurring in patients with temporomandibular disorders (TMD). During the study Electromyography Biofeedback (EMG-Biofeedback)- assisted training lowering muscle tension will be used. The patients will undergo 4 or 8 meetings of EMG-Biofeedback - assisted training Than the patients will be reevaluated after 6 and 12 weeks.

Outcome Measures

Primary Outcomes (4)

  • The effect of EMG biofeedback therapy on pain symptoms measured by Numerical Rating Scale (NRS) in Experimental group 1

    This effect will be assessed by comparing Numerical Rating Scale (NRS) pre- and post- biofeedback therapy. A numerical rating scale (NRS) requires the patient to rate their pain on a scale 0-10, where 0 is no pain and 10 is the worst pain imaginable

    before the treatment, after 4 weeks of training

  • The effect of EMG biofeedback therapy on pain symptoms measured by Numerical Rating Scale (NRS) in Experimental group 2

    This effect will be assessed by comparing Numerical Rating Scale (NRS) pre- and post- biofeedback therapy. A numerical rating scale (NRS) requires the patient to rate their pain on a scale 0-10, where 0 is no pain and 10 is the worst pain imaginable

    before the treatment, after 8 weeks of training

  • The effect of EMG biofeedback therapy on pain symptoms measured by pressure pain threshold in Experimental group 1

    This effect will be assessed by comparing pressure pain threshold pre- and post- biofeedback therapy. Pressure pain threshold will be measured with dolorimeter.

    before the treatment, after 4 weeks of training

  • The effect of EMG biofeedback therapy on pain symptoms measured by pressure pain threshold in Experimental group 2

    This effect will be assessed by comparing pressure pain threshold pre- and post- biofeedback therapy. Pressure pain threshold will be measured with dolorimeter.

    before the treatment, after 8 weeks of training

Secondary Outcomes (9)

  • Effect of EMG biofeedback therapy on psychological parameters and its persistence in time measured by Beck Anxiety Inventory (BAI).

    before the treatment and up to 12 weeks after completion of the treatment

  • Effect of EMG biofeedback therapy on psychological parameters and its persistence in time measured by Patient Health Questionnaire-9 (PHQ-9)

    before the treatment and up to 12 weeks after completion of the treatment

  • Effect of EMG biofeedback therapy on psychological parameters and its persistence in time measured by Perceived Stress Scale-10 (PSS-10)

    before the treatment and up to 12 weeks after completion of the treatment

  • Effect of EMG biofeedback therapy on psychological parameters and its persistence in time measured by Somatic Symptom Scale-8 (SSS-8).

    before the treatment and up to 12 weeks after completion of the treatment

  • Effect of EMG biofeedback therapy on sleep quality and its persistence in time measured by Pittsburgh Sleep Quality Index (PSQI)

    before the treatment and up to 12 weeks after completion of the treatment

  • +4 more secondary outcomes

Study Arms (3)

Control group

ACTIVE COMPARATOR

Patients with masticatory muscle pain treated with occlusal splint, physiotherapy and counseling

Other: Classic treatment for myogenous TMD

Experimental group 1

EXPERIMENTAL

Patients diagnosed with masticatory muscle pain treated with 4 meetings of EMG-biofeedback assisted training

Device: Electromyography Biofeedback

Experimental group 2

EXPERIMENTAL

Patients diagnosed with masticatory muscle pain treated with 8 meetings of EMG-biofeedback

Device: Electromyography Biofeedback

Interventions

EMG-Biofeedback- assisted training is a method in which electrodes situated on the surface of the skin detect small voltage changes which arise from the working muscles (in this case masseter and temporalis muscles). The voltage is transformed into a visual or sound time-variable signal which gives the patient feedback as he willingly tries to change the muscle tension (in this case to lower the excessive masseter tension)

Also known as: EMG-Biofeedback
Experimental group 1Experimental group 2

Combination of physiotherapy (manual therapy), stabilization occlusal splint usage and counseling
