Hypertonia, or high muscle tone, is a condition that causes muscles to be stiff and difficult to move. It is often seen in people with cerebral palsy, stroke, or severe head or spinal cord injuries. The condition can also be related to spasticity and dystonia. Hypertonia can affect both arms and legs, only the legs, just one side of the body, or even a single muscle group in a limb. It is caused by damage to the central nervous system, specifically the nerve pathways that control muscle activity. This damage results in abnormally increased muscle tone, leading to reduced muscle flexibility and loss of function. Treatment options include physical therapy, muscle stretching, inhibitory pressure, and in some cases, muscle-relaxing drugs.

Stretching exercises
When addressing hypertonic muscles, it is crucial to adopt a multifaceted approach that includes targeted relaxation exercises, manual therapy, and biofeedback. Progressive muscle relaxation, where individuals tense and then release each muscle group, can be highly effective in reducing hypertonicity. This involves slowly moving the affected body part through its available range of motion, stopping just before the body's natural stop point and gently returning to the starting position. This process can be repeated to help increase the range of motion over time.
For those experiencing hypertonic pelvic floor muscles, specific stretching exercises can provide immense relief. These stretches focus on promoting a sense of relaxation and reducing the sensation of tightness or tension in the pelvic floor muscles. Diaphragmatic breathing exercises can also be beneficial in alleviating tension and improving overall pelvic health.
Additionally, bridge exercises can be beneficial for individuals with hypertonic muscles. This involves laying on the back with knees bent and pushing the hips up towards the ceiling. The challenge can be increased by trying to fit toys under the "bridge" or stacking objects on the belly while maintaining the bridge position.
It is important to note that the treatment of hypertonic muscles should be tailored to individual needs, and seeking guidance from a qualified healthcare professional or therapist is essential for optimal results.

Physiotherapy
Hypertonia, or high muscle tone, is a condition characterised by an increased state of active muscle contraction, even when the body is at rest. It is often associated with rigidity and spasticity, and can be caused by damage to the central nervous system, particularly upper motor neuron lesions. The condition can affect both arms and legs (quadriplegia), only the legs (diplegia), or just one side of the body (hemiplegia). It can also manifest in infants and children, especially those with cerebral palsy or other pathological disorders such as stroke.
- Inhibitory Pressure: Applying firm pressure over the muscle tendon can help decrease hypertonia. This can be done by gently moving the affected body part through its available range of motion, stopping just before the point of resistance, holding for a few seconds, and then slowly returning to the starting position. This technique helps improve the range of motion and promotes muscle relaxation.
- Rhythmic Rotation: Slow, repeated rotations of the affected body part can stimulate muscle relaxation and improve joint flexibility.
- Splinting Techniques: Splinting can be valuable in extending the joint range of motion lost due to hypertonicity, helping to restore normal movement.
- Passive Movements: Quick, repeated passive movements of the affected joint in a cyclical fashion can help limit muscle tone and improve flexibility.
- Exercise and Patient Education: Isokinetic, aerobic, and strength training exercises, prescribed by a physiotherapist, can help improve muscle function and reduce hypertonia. It is important to avoid stressful situations that may trigger increased muscle tone.
For specific conditions, such as a hypertonic pelvic floor, working with a specialised pelvic physiotherapist is recommended. They can provide tailored strategies, including stretching exercises, diaphragmatic breathing exercises, and relaxation techniques, to alleviate muscle tension and improve overall pelvic health and quality of life.

Medication
Hypertonia is an abnormal increase in muscle tone caused by upper motor neuron lesions. It can be caused by injury, disease, or conditions that involve damage to the central nervous system. The condition is characterised by stiff and difficult-to-move arms and legs. It can be treated with medication, physical management, surgical interventions, and alternative treatments.
There is no single medication that serves as a gold standard for treating hypertonia. Treatment options are individualised depending on the level of hypertonicity, the patient's goals, and the underlying cause of the upper motor neuron lesion.
Muscle-relaxing drugs such as baclofen, diazepam, and dantrolene may be prescribed to reduce spasticity. All of these drugs can be taken by mouth, but baclofen may also be injected directly into the cerebrospinal fluid through an implanted pump. It is important to note that withdrawal from intrathecal baclofen can be dangerous, potentially leading to increased hypertonia, hyperthermia, seizures, and even death. Therefore, managing withdrawal requires supportive care and administering baclofen or benzodiazepines.
Botulinum toxin is often used to relieve hypertonia in specific areas of the body as its effects are localised. Phenol injections are also used to treat hypertonia, particularly in focal spasticity. Carbamazepine has been found to have a positive effect on neuromyotonia, a condition previously called stiff-man syndrome, which is characterised by stiffness in the limbs and in swallowing and mastication.

Exercise and patient education
Exercise
Isokinetic, aerobic, and strength-training exercises are recommended for patients with hypertonic muscles. These exercises should be prescribed by a physiotherapist and tailored to the individual's specific needs and limitations. It is important to bring the muscle through its full range of motion while placing it under constant tension to encourage muscle growth and improve mobility. This can be done through passive movements, such as slowly and safely moving the affected body part through its available range of motion. For example, bending the knee to assess increased tone in the leg.
Spinal Manipulative Therapy (SMT) can help restore joint motion and improve load sharing among the passive lumbar spine components, although this is often a short-term solution. Myofascial release techniques can also contribute to the normalization of the flexion-relaxation response, reducing pain and disability. Contract-relax and static stretching may provide short-term gains in range of motion, but the effects are not permanent.
Patient Education
Patient education is crucial in managing hypertonic muscles. Patients should be made aware of the importance of avoiding noxious stimuli and providing frequent range-of-motion exercises. They should also be educated about the potential benefits of chiropractic care and heat therapies. Additionally, patients should be encouraged to move regularly and avoid prolonged sedentary postures, as these can pre-tax their muscles and lead to dysfunctional hypertonicity.
In some cases, hypertonic muscles may be caused by more severe neurological problems, such as spinal cord injury or neurodegenerative diseases like Parkinson's. Therefore, it is important for patients to be educated about the warning signs and symptoms of these more serious conditions and to seek medical advice if they suspect their hypertonicity is caused by something other than muscle tension.

Chiropractic care
Chiropractors can employ several techniques to alleviate hypertonic muscles and the associated symptoms. One such technique is spinal manipulation or spinal manipulative therapy (SMT), which involves realigning the vertebrae and joints to reduce pain and improve range of motion. This can be achieved through the direct thrust technique, where chiropractors apply gentle force to guide spinal components back into proper alignment, or the indirect positional technique, which targets the full range of motion to correct posture and joint movement issues caused by hypertonic muscles.
Soft tissue therapy is another crucial aspect of chiropractic care for muscle hypertonicity. This includes myofascial release therapy, which focuses on identifying and releasing trigger points in the myofascial tissue, a membrane layer that covers and connects muscles. By applying pressure to these trigger points, chiropractors can reduce pain and restore free movement. Soft tissue therapies can also involve instrument-assisted soft tissue manipulation (IASTM) and proprioceptive neuromuscular facilitation (PNF) to address muscular adhesions and restore proper joint motion.
Chiropractors may also recommend specific exercises and stretches as part of the patient's "homework" to extend the benefits of the chiropractic adjustments. These exercises can include movement re-training and postural alteration to prevent ongoing overloading of the joints. Additionally, chiropractors may advise on ergonomics, icing/heat therapy, diet, and stress management techniques to help relax muscles and improve overall health.
