Comparative study of the Immediate Effect between the Multiplane Force Application (MFA) and Ischemic Compression (IC) of Masticatory Muscles: a Randomized Controlled Trial

Phase 1

Completed

• Conditions: Myofascial pain syndrome (MPS) is a complex pain disorder which is identified by a specific pattern of somatic referred pain of myofascial trigger point (MTrP) [1]. MTrPs are clinically classified as; multiplane force application technique, ischemic compression technique, latent myofascial trigger point

Inclusion Criteria

-Healthy participants without pain (male and female), aged between 18 to 60 years old.
-Healthy participants with previous history pain at the masticatory and neck muscles.
-Interested in this study and sign consent form.
-Participants who present of latent myofascial trigger point (LTrPs) or a tender spot in a taut band in muscles such as masseter, temporalis, sternocleidomastoid, upper trapezius muscles. Participants who had assessed by the physiotherapist. The presence of LTrP was determined using the diagnostic criteria described by Simons et al. (1999):
1)presence of a palpable taut band in a skeletal muscle,
2)presence of a hypersensitive tender spot in the taut band,
3)local twitch response provoked by the snapping palpation of the taut band, and
4)reproduction of the typical referred pain pattern of the myofascial trigger point (MTrP) in response to compression
For criteria 4, MTrP pressure pain threshold is assessed using a mechanical pressure algometer.
The assessor applied continuous pressure with the algometer at approximately a rate of 1 kg/cm 2/s, until it recorded a pressure of 2.5 kg/cm2. Pressure thresholds lower than 3 kg are considered to be abnormally low (Fischer, 1996). If the referred pain evoked by the MTrP was obtained before 2.5 kg/cm2, criteria 4 are seen to be fulfilled.
-No signs and symptoms of serious musculoskeletal, neurological or cardiopulmonary conditions.
-No physical deformities or psychiatric disorders.
-Good consciousness and co-operation.

Exclusion Criteria

-Healthy participants with previous history of following conditions were excluded.
a) ostheoarthrosis, or arthritis of the TMJ
b) traumatic injuries or accident on cervical spine or TMJ (e.g., contusion, fracture, and whiplash injury) within 6 months before participating in this study
c) previous surgical on cervical spine or TMJ
d) neurological disorders (e.g.,trigeminal neuralgia)
e) underlying diseases such as fibromyalgia or cancer
-Healthy participants who not be able to follow instructions or have an adequate communication.
