Muscle Contraction And Tinnitus: Is There A Link?

can muscle contraction cause tinnitus

Tinnitus is a perception of sound without an external acoustic stimulus, affecting 10-17% of the world's population. Somatosensory tinnitus is a specific subgroup that can be caused by forceful muscle contractions in the head, neck, and limbs. While tight neck muscles may cause pulsatile tinnitus, it is not the most common cause, with vascular issues being more likely to result in tinnitus. However, ongoing muscular tension in the neck can lead to chronic neck pain, which can, in turn, lead to tinnitus. Muscular tinnitus is associated with involuntary spasms or twitching of the tiny stapedius and tensor tympani muscles in the middle ear, which control the movement of bones that carry sound to the inner ear. Treatment for muscular tinnitus includes muscle relaxants, physical therapy, electrical stimulation, and surgery, if necessary.

Muscle tension in the neck and jaw

The neck and jaw are closely connected, so issues in one area often affect the other. Temporomandibular disorders (TMD) are common in individuals with muscle tension in the jaw and neck and can lead to chronic tinnitus. TMD affects the temporomandibular joint, which connects the lower jaw and skull, causing inflammation and pain. This inflammation can result in damage to the joint, leading to chronic tinnitus.

To relieve muscle tension in the neck and jaw, various treatments are available. Jaw exercises, such as gentle stretching and relaxation techniques, can help improve muscle mobility and reduce pain. Additionally, soft food diets and mouthguards can assist in preventing teeth grinding and reducing jaw tension. In some cases, medical interventions like muscle relaxers, Botox injections, or, as a last resort, jaw surgery, may be recommended to address severe or persistent issues.

It is important to note that ongoing muscular tension in the neck can lead to chronic neck pain, which has been associated with tinnitus. This condition is known as cervical tinnitus, and it can cause additional symptoms such as vertigo, tingling hands, headaches, and ear popping. Therefore, addressing muscle tension in the neck and jaw through the aforementioned treatments can help prevent the development or worsening of tinnitus and improve overall quality of life.

While the exact relationship between muscle tension and tinnitus is not fully understood, researchers have identified a connection. The tension in the cervical spine muscles can lead to overstimulation of the cochlear nucleus, resulting in tinnitus. Additionally, the psychoacoustic attributes of tinnitus, such as loudness and pitch, can be temporarily changed by forceful muscle contractions in the head and neck.

Temporomandibular joint disorder

Muscle contractions can cause tinnitus, which is the perception of sound in the absence of an acoustic external stimulus. This is known as muscular tinnitus and is associated with involuntary spasms or twitching of the tiny stapedius and tensor tympani muscles in the middle ear. The sound that muscular tinnitus creates is usually a clicking noise.

TMD can lead to muscular tension in the jaw and neck, which can contribute to tinnitus. This is known as somatosensory tinnitus, which is influenced by inputs from the somatosensory system. The intense muscular tension associated with TMD can lead to chronic neck pain, which is a known cause of tinnitus. Additionally, the damage to the temporomandibular joint in TMD can result in inflammation, causing pain and potentially affecting hearing.

Treatment for TMD-related tinnitus aims to reduce muscular tension. This includes performing stretching exercises, rotation movements, and relaxation techniques. Simple treatments such as eating soft foods, applying heat or cold to the face, and taking over-the-counter anti-inflammatory medications are often recommended. Additionally, reducing habits like jaw clenching, gum chewing, and nail biting can help manage TMD and associated tinnitus.

In some cases, more complex treatments may be considered, such as those involving needles or other instruments to target the chewing muscles or temporomandibular joints. However, these treatments should be approached with caution, as they may not be effective and could potentially worsen the condition. It is essential to consult with qualified medical or dental specialists before undergoing any invasive procedures.

Somatosensory tinnitus

The somatosensory system is a part of the sensory nervous system that responds to changes in the body, such as movement, pressure, touch, temperature, or pain. Somatosensory tinnitus occurs when changed somatosensory information from the jaw area or cervical spine (the neck) causes or alters the perception of tinnitus. This changed information is transported to the brain by neural fibres from cell bodies located in the dorsal root ganglia or the trigeminal ganglion. The somatosensory system can influence the pitch or loudness of the tinnitus by altering the spontaneous rates or synchrony of firing among neurons in the cochlear nucleus, inferior colliculus, or auditory cortex.

The existence of somatosensory tinnitus as a subtype of tinnitus is widely accepted. However, its pathophysiology, assessment, and treatment are not well defined, and it can be challenging to diagnose. Researchers have developed ways to lessen the symptoms of somatosensory tinnitus, and if the underlying cause can be identified and treated, the tinnitus may resolve. Treatment options include cervical spine physiotherapy, orofacial physiotherapy, splint treatment, and repetitive exercises.

Degenerative diseases

Tinnitus is the perception of sound in the absence of an acoustic external stimulus. It is commonly described as a ringing sound, but some people hear other types of sounds, such as roaring or buzzing. Surveys estimate that 10 to 25% of adults experience tinnitus, and it can occur in children too. While tinnitus is usually not severe enough to interfere with daily life, it can affect one's mood, sleep, and concentration. In severe cases, it can lead to anxiety or depression.

Muscular tinnitus is associated with involuntary spasms or twitching of the tiny stapedius and tensor tympani muscles in the middle ear, which control the movement of the bones that carry sound from the air to the inner ear. These muscles contract to reduce the volume of loud noises, and if they contract rhythmically, clicking or other repetitious sounds may be heard.

Several degenerative diseases that affect the head and neck can cause muscular tinnitus, including:

  • Amyotrophic lateral sclerosis (ALS) or Lou Gehrig's disease
  • Multiple sclerosis
  • Palatal myoclonus, which involves muscle spasms in the roof of the mouth
  • Otosclerosis, a middle-ear condition

In addition to degenerative diseases, muscular tinnitus can also be caused by forceful muscle contractions in the head, neck, and limbs, as well as other factors such as head and neck injuries, teeth grinding, and jaw clenching.

Tension syndrome

Muscular tinnitus is a type of tinnitus that is caused by muscle contractions or spasms. It is often associated with involuntary spasms or twitching of the tiny stapedius and tensor tympani muscles in the middle ear. These muscles control the movement of the bones that carry sound from the air to the inner ear. The muscles contract to reduce the volume of loud noises. If they contract rhythmically, a person may hear clicking or other repetitious sounds.

Tinnitus is the perception of sound in the absence of an external acoustic stimulus. It affects 10-17% of the world's population and is a complex symptom with multiple causes, influenced by pathways other than the auditory one. Somatosensory tinnitus is a type of tinnitus that is influenced by the somatosensory system, which is a part of the sensory nervous system. The psychoacoustic attributes of tinnitus (loudness and pitch) might be changed immediately, though only temporarily, by different stimuli, such as forceful muscle contractions of the head, neck and limbs.

Frequently asked questions

Tinnitus is the perception of sound in the absence of an acoustic external stimulus. It affects 10–17% of the world's population and is a complex symptom with multiple causes, influenced by pathways other than the auditory one.

Yes, muscle contractions can cause tinnitus. Tension in the neck and cervical area can lead to chronic neck pain, which in turn can lead to tinnitus. Conditions that trigger random involuntary movements, tremors, or extended muscle contractions can also cause tinnitus.

If the cause of muscular tinnitus is diagnosed and treated, it may be resolved. Doctors may suggest muscle relaxation, physical therapy, or electrical stimulation to reduce the symptoms. Performing neck stretches regularly may also help relax the neck muscles.
