Hyperhidrosis (Excessive Sweating)

Hyperhidrosis is a condition characterised by excessive sweating beyond what is required for normal temperature regulation. It commonly affects the underarms, hands, feet, and face, and can significantly impact daily life, confidence, and social interactions.

Many patients report needing to change clothing frequently, difficulty with handshakes or writing, and avoidance of social or professional situations.

What causes hyperhidrosis?

Hyperhidrosis is usually due to overactivity of the nerves that stimulate sweat glands.

It may occur:

• Without an identifiable cause (primary hyperhidrosis)
• In association with medical or neurological conditions (secondary hyperhidrosis)

How treatment works

Botulinum toxin is injected into the affected area to block the nerve signals that activate sweat glands.

This results in:

• Reduced sweating in the treated area
• Improved comfort and confidence
• Minimal systemic side effects

Who this is for

This treatment may be suitable for patients with:

• Axillary (underarm) hyperhidrosis
• Palmar (hand) hyperhidrosis
• Plantar (foot) hyperhidrosis
• Facial sweating

It is particularly useful for patients who:

• Have not responded to topical treatments
• Prefer to avoid oral medications
• Require a longer-lasting solution

What to expect

• Performed in the clinic
• Multiple small injections to the affected area
• Typically takes 15–30 minutes
• Minimal downtime

Results usually begin within 1–2 weeks and last 4–6 months.

How this differ from other treatments

Hyperhidrosis can be managed in several ways:

• Topical treatments (e.g. antiperspirants) — often first-line but may be insufficient
• Oral medications — may have systemic side effects
• Botulinum toxin — provides a targeted, local treatment with predictable results

When to consider referral

Referral may be appropriate for patients with:

• Persistent excessive sweating affects daily activities
• Significant impact on work, social interaction, or confidence
• Inadequate response to topical or medical therapies

Typically 4–6 months.

Is it painful?
Generally well tolerated with minimal discomfort.

Are there side effects?
Side effects are usually mild and localised.

Sialorrhoea (Excessive Drooling)

Sialorrhoea, or excessive drooling, is commonly seen in neurological conditions and is usually due to impaired swallowing rather than increased saliva production.

It can lead to:

• Social discomfort
• Skin irritation
• Increased risk of aspiration
• Difficulty with communication

How treatment works

Botulinum toxin is injected into the parotid and submandibular glands to reduce saliva production.
At GC Rehab, all injections are performed under ultrasound guidance to improve precision and safety.

Who this is for

This treatment may be suitable for patients with:

• Stroke
• Parkinson’s disease
• Motor neurone disease
• Cerebral palsy
• Other neurological conditions affecting swallowing

What to expect

• Performed in the clinic
• Ultrasound-guided injections to the salivary glands
• Typically well tolerated
• Effects usually last 3–6 months

How this differs from other treatments

Other options may include:

• Oral medications (often limited by side effects)
• Behavioural strategies or therapy

Botulinum toxin provides a targeted approach by directly reducing saliva production at the gland level.

When to consider referral

Referral may be appropriate when:

• Drooling is persistent or worsening

Longer-lasting relief for spasticity and pain

Cryoneurolysis is an emerging treatment for patients seeking longer-lasting relief from spasticity and pain.

At GC Rehab, we offer cryoneurolysis as part of a comprehensive neurorehabilitation approach, combining procedural expertise with functional rehabilitation.

What is cryoneurolysis?

Cryoneurolysis uses controlled cold temperatures to temporarily disrupt nerve signalling.

This can:

• Reduce pain
• Decrease muscle overactivity
• Improve movement and function

The nerve is not destroyed — it gradually regenerates over time, allowing for repeatable treatment.

Who this is for

Cryoneurolysis may be suitable for patients with:

• Spasticity (e.g. stroke, brain injury, multiple sclerosis)
• Post-stroke muscle overactivity
• Peripheral nerve pain
• Osteoarthritis-related pain (e.g. knee pain via genicular nerves)
• Focal musculoskeletal pain syndromes

It is particularly useful when:

• Symptoms persist despite therapy or medications
• Botulinum toxin provides a limited or short-lived benefit
• Function is restricted (e.g. walking, hygiene, limb positioning)

Common treatment targets

Depending on the condition, commonly treated nerves include:

• Tibial nerve branches (spasticity affecting the calf and foot)
• Musculocutaneous nerve (upper limb spasticity)
• Genicular nerves (knee osteoarthritis pain)
• Peripheral sensory nerves for focal pain

What to expect

• Performed in the clinic
• Ultrasound-guided placement of a specialised probe
• The procedure typically takes 60 to 90 minutes per limb
• Minimal downtime

Relief can last several months, depending on the nerve treated.

How this differs from other treatments

Cryoneurolysis targets the nerve directly.

• Botulinum toxin acts at the muscle level
• Medications provide systemic, often temporary relief
• Surgery is more invasive and not always appropriate

Cryoneurolysis provides a targeted, reversible option with a longer duration than many non-surgical treatments.

When to consider referral

Referral may be appropriate for patients with:

• Focal spasticity limiting function or care
• Pain not responding to conservative treatment
• Difficulty with gait, hygiene, or limb positioning
• Recurrent symptoms despite standard therapies

Why GC Rehab

Specialist rehabilitation physician with experience in spasticity management and ultrasound-guided nerve procedures, including early clinical use of cryoneurolysis in Australia.

FAQs

How long does cryoneurolysis last?
Relief typically lasts several months.

Is it safe?
Yes, when performed with appropriate technique and ultrasound guidance.

Can it be repeated?
Yes, as nerves regenerate over time.

Bruxism (Teeth Grinding and Jaw Clenching)

Bruxism refers to involuntary teeth grinding or jaw clenching, often occurring during sleep or periods of stress. It is a common cause of jaw pain, headaches, and migraines, and can also contribute to temporomandibular joint (TMJ) dysfunction and tooth wear.

Many patients are unaware they have bruxism until symptoms such as morning headaches, jaw tightness, or facial pain develop.

How bruxism causes headaches and migraines

Overactivity of the jaw muscles (particularly the masseter and temporalis) can place sustained tension on the head and neck.

This may lead to:

• Tension-type headaches
• Migraine exacerbation
• Facial pain and pressure
• Neck and shoulder tightness

Treating the underlying muscle overactivity can significantly reduce these symptoms.

How treatment works

Botulinum toxin is injected into the masseter and temporalis muscles to reduce excessive muscle activity.

This can:

• Relieve jaw tension
• Reduce headaches and migraines
• Improve comfort when chewing or speaking
• Help prevent further dental damage

Treatment is tailored based on symptom pattern and muscle involvement.

Who this is for

This treatment may be suitable for patients with:

• Jaw clenching or teeth grinding (awake or during sleep)
• Chronic headaches or migraines with a muscular component
• TMJ-related pain
• Facial muscle tightness or fatigue
• Limited benefit from mouthguards or other conservative measures

What to expect

• Performed in clinic
• Targeted injections to jaw muscles
• Typically takes 10–20 minutes
• Minimal downtime
• Effects usually begin within 1–2 weeks and last 3–6 months

How this differs from other treatments

Unlike mouthguards or medications, botulinum toxin directly targets the source of muscle overactivity.

• Mouthguards protect teeth but do not reduce muscle tension
• Pain medications provide temporary relief only
• Botulinum toxin reduces the underlying muscle activity

This makes it a useful option for patients with persistent symptoms.

Why GC Rehab

Specialist rehabilitation physician with experience in movement disorders and ultrasound-guided injections.

FAQs

Can this help migraines?
Yes, particularly when migraines are triggered or worsened by jaw muscle tension.

Will it affect chewing?
Treatment is targeted to reduce overactivity while preserving normal function.

How long does it last?
Typically 3–6 months.

Is it safe?
Yes when performed by an experienced clinician.

What is Cervical Dystonia/Torticollis?

Cervical dystonia, also known as spasmodic torticollis, is a neurological disorder that causes involuntary muscle contractions in the neck, leading to abnormal head movements and postures. It is a rare condition, affecting approximately 1 in 5,000 people.

Symptoms:

The symptoms of cervical dystonia can vary from person to person and may include:

• Abnormal posture of the head and neck

What is an Intrathecal Baclofen Pump?

An Intrathecal Baclofen Pump, also known as an intrathecal drug delivery system, is a specialised medical device that delivers a controlled amount of the muscle relaxant medication Baclofen directly into the spinal fluid. It is primarily used to manage severe spasticity or muscle stiffness caused by conditions such as multiple sclerosis, cerebral palsy, spinal cord injuries, or other neurological disorders.

How Does the Intrathecal Baclofen Pump Work?

The Intrathecal Baclofen Pump consists of a small pump reservoir that is surgically implanted under the skin of your abdomen or back. The pump is connected to a catheter, which is carefully threaded into the intrathecal space surrounding your spinal cord. The Baclofen is continuously delivered through the catheter, targeting the nerve receptors in the spinal fluid to reduce spasticity.

Benefits of Intrathecal Baclofen Pump:

• Targeted Treatment: The pump delivers Baclofen directly to the spinal fluid, providing more precise and effective spasticity management compared to oral medications.
• Reduced Side Effects: Since the medication bypasses the digestive system, the pump may minimise systemic side effects like drowsiness or dizziness.
• Improved Functioning: Better spasticity control can lead to improved mobility and overall quality of life.

The Intrathecal Baclofen Pump Implantation Procedure:

The implantation of the Intrathecal Baclofen Pump involves several steps:

1. Pre-Procedure Assessment: Your healthcare provider will conduct a thorough evaluation of your spasticity, review your medical history, and discuss the potential benefits and risks of the procedure.
2. Surgical Implantation: The pump reservoir is placed under your skin, and the catheter is inserted into the intrathecal space during a surgical procedure. You will be under anaesthesia for comfort during the surgery.
3. Pump Programming: After the implantation, your healthcare provider will program the pump to deliver the appropriate dosage of Baclofen tailored to your specific needs.
4. Follow-Up Care: Regular follow-up visits will be scheduled to monitor the pump's functioning and make any necessary adjustments to the Baclofen dosage.

The Intrathecal Baclofen Pump Refill Procedure:

The Intrathecal Baclofen Pump requires periodic refills to maintain an appropriate level of Baclofen in your system. The refill procedure involves the following steps:

1. Appointment Scheduling: Your healthcare provider will schedule regular appointments for Baclofen pump refills based on your individual needs.
2. Pre-Refill Assessment: Before the procedure, your healthcare provider will evaluate your spasticity levels, review your medical history, and check the pump settings to determine the appropriate Baclofen dosage.
3. Refill Procedure: During the procedure, a thin needle is inserted through the skin and into the port of the Baclofen pump. The medication is then delivered directly into the pump reservoir, where it can be slowly released into the spinal fluid.
4. Monitoring: After the refill, you may be monitored for a short time to ensure there are no adverse reactions.

Importance of Timely Refills:

Timely refills of your Intrathecal Baclofen Pump are essential to maintain effective spasticity control and manage your symptoms optimally. Missing or delaying refills may lead to an increase in spasticity and a decrease in your overall comfort and mobility.

Post-Refill Care:

• Follow your healthcare provider's instructions regarding medication dosage and usage.
• Keep track of any changes in your spasticity levels and report them to your healthcare provider during follow-up visits.
• Ensure that your Intrathecal Baclofen Pump is functioning correctly and properly maintained.

Possible Risks and Complications:

While Intrathecal Baclofen Pumps are generally safe and effective, some potential risks and complications may include infection, bleeding, catheter-related issues, or drug-related side effects. Your healthcare provider will carefully monitor and address any concerns during your treatment.

Please feel free to reach out if you have any questions or concerns about the Intrathecal Baclofen Pump, its refills, or any other aspect of your treatment.

What are Platelet-Rich Plasma (PRP) Injections?

Platelet-rich plasma (PRP) injections involve using a concentrated solution derived from your own blood. This solution contains a higher concentration of platelets than regular blood, which are responsible for promoting healing and tissue repair in the body.

The PRP Injection Process:

1. Blood Collection: A small amount of your blood is drawn, usually from your arm.
2. Centrifugation: The collected blood is placed in a centrifuge, which spins at a high speed to separate the platelets from other blood components.
3. Concentration: The centrifugation process separates the platelets, and the resulting platelet-rich plasma is collected.
4. Injection: The PRP is then carefully injected into the site of injury or affected area, such as joints, tendons, ligaments, or muscles.

Conditions Treated with PRP Injections:

PRP injections are commonly used in the treatment of conditions such as:

• Tendinitis (e.g., tennis elbow, Achilles tendinitis)
• Ligament injuries
• Muscle strains
• Osteoarthritis

How PRP Injections Work:

Platelets play a crucial role in the body's healing process, as they contain growth factors and other bioactive proteins that stimulate tissue regeneration and repair. When injected into an injured area, PRP is believed to promote a more robust healing response and potentially accelerate recovery.

Benefits of PRP Injections:

• Non-surgical: PRP injections are minimally invasive and do not require surgery.
• Natural healing: PRP uses your own blood, reducing the risk of allergic reactions or adverse effects.
• Potential for faster recovery: PRP may accelerate the healing process, allowing you to return to activities sooner.

Risks and Side Effects:

While PRP injections are generally considered safe, some potential risks and side effects include:

• Pain or discomfort at the injection site
• Mild swelling or bruising
• Infection (rare)

Our specialist physicians will discuss the benefits, risks, and expected outcomes of PRP injections based on your specific condition.

Consultation and Assessment:

It's essential to consult with a qualified healthcare professional to determine if PRP injections are a suitable treatment option for your specific musculoskeletal condition. Your healthcare provider will carefully assess your medical history, perform a physical examination, and consider other treatment options before recommending PRP therapy.

Please feel free to reach out if you have any questions or concerns about PRP injections or any other aspect of your treatment.
