Official title
Comparative Study of Dry Needling Vs Transcutaneous Electrical Nerve Stimulation in Management of Patient with Myofascial Pain Dysfunction Syndrome Using Electromyography and Visual Analogue Scale: a Randomized Clinical Trial
Overview
Myofascial pain dysfunction syndrome (MPDS) is the most common form of temporomandibular disorders. Because of the multifactorial nature of the problem, its management is still not definite. This randomized clinical trial aimed to assess the efficacy of transcutaneous electrical nerve stimulation over dry needling for management of such condition.
Detailed description
Myofascial pain syndrome (MPS) is a prevalent affliction among individuals experiencing musculoskeletal pain issues. This condition is characterized by pain originating from the muscle and surrounding fascia. Patients typically exhibit localized pain in a confined region or referred pain with diverse patterns.
Additionally, physical examinations may reveal trigger points on the affected muscles. MPS can be categorized into acute and chronic forms. Acute MPS often resolves spontaneously or with uncomplicated treatments. However, chronic MPS typically has a poorer prognosis, and symptoms may persist for six months or more.
Dry needling involves the insertion of a solid filiform needle into a trigger point without the administration of any substance. Various theories have been put forth to explain the mechanisms by which dry needling alleviates pain . These include the \"gate control\" theory, modulation of endogenous opioids such as B-endorphin, encephalins, and dynorphins, disruption of central sensitization through activation of Aβ fibers resulting in inhibition of synaptic transmission between Aβ and C fibers and cells of the spinal cord dorsal horn due to their slower impulse conduction, and even placebo effects have been suggested . When a needle is inserted into a trigger point, it may elicit a local twitch response. This reflexive contraction of the trigger point can also facilitate physiological changes, including the reduction of spontaneous electrical activity and the concentration of inflammatory and nociceptive chemicals, ultimately resulting in the relaxation of the trigger point.
Transcutaneous electrical nerve stimulation (TENS) is considered to be a highly secure and cost-effective modality for managing both chronic and acute pain. As per the gate control theory, TENS employs low voltage electrical pulses that are applied to the central nervous system. The modulation of pain perception induced by TENS is attributed to the recruitment of Aβ afferent fibers in the posterior horn of the spinal cord, which prevents the activation of pain conducted in thin fiber. Electrical stimulation effectively inhibits the transmission of painful impulses through the spinal cord and stimulates the release of endogenous opioids by the brain. Its safe, noninvasive, inexpensive and effective method of providing analgesia with reduced potential adverse effects compared to other treatment modalities.
In this research, we aim to evaluate TENS is a suitable treatment for MPDS patients, which would eliminate the need for another treatment modality. The expected benefit in this study is to find the best treatment for MPDS reducing pain, muscle stiffness and limited mouth opening.
Interventions
- Procedure TENS
Non-pharmacological method which is widely used by medical and paramedical professionals for the management of acute and chronic pain using electric pulse generator, lead wires and electrodes. - Procedure Dry Needle
Invasive procedure where a fine needle or acupuncture needle is inserted into the skin and muscle.
Primary outcome measures
- Pain [Time frame: From enrollment to the end of treatment at 6 months]
Secondary outcome measures (5)
- Muscle stiffness [Time frame: From enrollment to the end of treatment at 6 months]
