Navigating Parkinson’s Disease: Speech Therapy, Physical Therapy, Treatments & More

February 24, 2025

1. Parkinson’s Disease Overview

Parkinson’s Disease (PD) is a progressive neurological disorder that affects movement, speech, and overall motor function. It results from the degeneration of dopamine-producing neurons in the brain. This dopamine deficiency leads to hallmark symptoms such as tremors, rigidity, bradykinesia (slowness of movement), and postural instability.

Beyond motor symptoms, Parkinson’s also impacts cognition, mood, and autonomic functions, leading to issues such as depression, anxiety, sleep disturbances, and changes in speech and swallowing. While there is no cure for Parkinson’s Disease, various treatments and therapies can help manage symptoms and improve quality of life.


2. Parkinson’s Disease Treatment

While no single treatment halts the progression of Parkinson’s Disease, a combination of medications, therapies, and lifestyle changes can help manage symptoms effectively.

Medications for Parkinson’s Disease

  • Levodopa/Carbidopa (Sinemet): Considered the most effective medication for managing the motor symptoms of PD by helping to replenish dopamine levels.
    • This drug is often started in mid to later stages of PD when symptoms like tremor, rigidity, and bradykinesia significantly impact daily life.
    • Dose adjustments, extended-release formulations (like Rytary), and combination with other medications (like MAO-B inhibitors or COMT inhibitors) can help manage long-term challenges.
    • Long term side effects include motor fluctuations (“on-off” phenomenon) (i.e., periods where the medication’s effects wear off before the next dose), dyskinesia (involuntary, erratic movements (twitching, jerking) after years of use) and freezing (sudden, temporary inability to move).
    • Despite complications, Levodopa remains the gold standard because it provides the best symptom relief. Still, it’s important to note that while Levodopa is highly effective for motor symptoms, it generally does not help with non-motor symptoms, balance issues, or falls.
  • Dopamine Agonists: Mimic dopamine in the brain and include drugs like pramipexole (Mirapex) and ropinirole (Requip).
    • These drugs mimic dopamine’s action by directly stimulating dopamine receptors.
    • Often used in early PD to delay the need for Levodopa or in later stages to smooth out motor fluctuations.
    • Less likely to cause dyskinesia than Levodopa initially, but they have side effects like sleep attacks, hallucinations, and impulse control disorders.
  • MAO-B Inhibitors: By irreversibly inhibiting MAO-B, these drugs prevent or reduce dopamine breakdown; includes the drugs selegiline (Eldepryl, Zelapar, EMSAM) and rasagiline (Azilect).
    • Both these drugs help prolong dopamine activity and are commonly used to delay the need for levodopa or to enhance its effects in later stages of Parkinson’s disease.
  • COMT Inhibitors: Used alongside Levodopa to prolong its effect.
    • These drugs help improve the effectiveness of Levodopa by preventing its breakdown, thereby extending its duration of action and reducing motor fluctuations.
    • Side effects include increased dyskinesia (due to higher dopamine levels), Nausea, diarrhea, or abdominal discomfort, dizziness/low blood pressure, and sleep disturbances.

Surgical Treatments: Deep Brain Stimulation (DBS)

Deep Brain Stimulation (DBS) is a procedure where small electrodes are placed in specific areas of the brain to help control abnormal movement signals. For the right candidate—typically someone with Parkinson’s disease for several years who experiences motor fluctuations and involuntary movements despite medication, with good cognitive function and stable mental health—DBS can greatly reduce tremors and improve movement when medications alone are no longer enough. While DBS can enhance motor control and reduce medication needs, it does not improve symptoms like speech difficulties, swallowing problems, or balance issues, which may continue to worsen as the disease progresses.

Parkinson’s Disease Centers of Excellence

For top-tier care, Parkinson’s Disease Centers of Excellence (designated by the Parkinson’s Foundation) provide specialized treatment and research opportunities. These centers integrate expert movement disorder specialists, physical and speech therapists, and access to clinical trials, ensuring patients receive the latest treatment advancements. You can find a list of these centers through the Parkinson’s Foundation website.

If you or a loved one suspects Parkinson’s disease or has been diagnosed, it’s highly recommended to seek, at minimum, a consultation with a neurologist at a Parkinson’s Disease Center of Excellence.


3. Speech and Swallowing Therapy for Parkinson’s Disease

How Parkinson’s Affects Speech and Swallowing

Speech issues, known as hypophonia, cause a person’s voice to become softer, making communication difficult. In addition to a low speaking volume, other symptoms include:

  • Monotone voice with reduced inflection
  • Mumbled or slurred speech due to reduced articulation
  • Breathy or hoarse voice from weak vocal cords

In addition to speech, swallowing difficulties (dysphagia) are a significant concern. Up to 80% of people with Parkinson’s experience some level of dysphagia, which can lead to:

  • Coughing or choking while eating
  • Difficulty swallowing pills
  • Unintentional weight loss or malnutrition
  • Aspiration pneumonia (food or liquid entering the lungs)

Working with a Speech-Language Pathologist (SLP) trained in Parkinson’s therapy is crucial. Two evidence-based programs stand out:

LSVT LOUD for Speech and Swallowing

The Lee Silverman Voice Treatment (LSVT LOUD) is an intensive voice therapy program that helps individuals speak louder and clearer through structured vocal exercises.

Since speech and swallowing rely on many of the same muscles, the vocal exercises in LSVT LOUD also contribute to strengthening swallowing function. More specifically, LSVT LOUD helps swallowing by:

  • Strengthening respiratory control and vocal cord muscles, improving breath support for swallowing.
  • Encouraging stronger vocal fold closure, reducing the risk of aspiration.
  • Enhancing oral and throat muscle coordination for safer swallowing.

After completing LSVT LOUD therapy, the LOUD for LIFE maintenance program is available, offering both in-person community-based speech exercise classes or virtual sessions.

You can locate a LSVT-certified clinician through their directory, here. If you are having trouble locating a therapist, you can reach out to LSVT directly. Tele-therapy sessions are available.

LSVT is covered by Medicare and many private insurance providers. Check with your insurer to confirm coverage.

SPEAK OUT! and Swallowing Therapy

SPEAK OUT!, developed by the Parkinson Voice Project, a 501 (c)(3) nonprofit organization committed to help individuals with Parkinson’s Disease and related disorders regain and retain their speech and swallowing functions. It trains individuals to use intentional speech rather than relying on automatic muscle function. In practice, SPEAK OUT! follows a very similar approach to LSVT LOUD.

And, since many of the muscles involved in speech and swallowing overlap, SPEAK OUT! therapy strengthens swallowing function as well.

The Parkinson Voice Project also offers free recorded virtual SPEAK OUT! sessions, which you can access here. Additionally, you can join live sessions Monday through Friday at 10 a.m. Central Time at the same link.

While virtual sessions are a great option for supplemental or maintenance therapy, it is recommended to start with personalized therapy from a SPEAK OUT! certified clinician. Your clinician will also help you obtain a SPEAK OUT! workbook, provided free through the Parkinson Voice Project (donations encouraged).

Therapy is covered by Medicare and many insurance providers, and many therapists offer virtual sessions. For example, in Arizona, SLPs like Megan Momeyer of Loving Speech Center provide SPEAK OUT! via teletherapy. Additionally, the Parkinson Voice Project maintains a database of SPEAK OUT! providers (in the U.S. and abroad), as well as SPEAK OUT! Therapy & Research Centers. These centers eliminate insurance and financial barriers by offering SPEAK OUT! therapy virtually through universities across the U.S.

Similar to LSVT LOUD’s LOUD for LIFE, this program includes The LOUD Crowd, a maintenance program that reinforces speaking and swallowing skills long-term. The LOUD Crowd also offers a great opportunity for connection and social engagement. The LOUD Crowd is available virtually and may also be offered in-person in some locations.

While both LSVT LOUD and SPEAK OUT! are incredibly effective for maintaining and improving swallowing function, an SLP may recommend a modified diet, swallowing exercises, or techniques like the chin-tuck maneuver if swallowing difficulties progress.


4. Physical Therapy for Parkinson’s Disease

Regular movement and physical therapy are essential to maintaining mobility, flexibility, and independence.

LSVT BIG: Parkinson’s-Specific Physical Therapy

LSVT BIG is an intensive movement therapy program designed to counteract bradykinesia (slow movements) by encouraging big, exaggerated movements that help with:

  • Walking speed and stride length
  • Balance and posture
  • Arm and leg coordination

Other Effective Physical Therapy and Exercise Programs

  1. High-Intensity Interval Training (HIIT): Increases endurance and neuroplasticity and includes Rock Steady Boxing.

    • For more information, check out this Yale study which found that high-intensity exercise can help reverse neurodegeneration in Parkinson’s disease by promoting brain plasticity and slowing disease progression. Regular vigorous physical activity improved motor function and brain health in patients. Researchers emphasized that exercise offers a non-invasive, cost-effective way to enhance quality of life for people with Parkinson’s. Read more here.


    • HIIT includes Rock Steady Boxing, which is has been shown to be effective in improving motor skills, balance, strength, and coordination through non-contact boxing exercises.


    • Programs like Rock Steady Boxing also boost mental health and quality of life by promoting social interaction and confidence. Regular participation has shown to increase mobility and delay the need for higher medication doses, making it a valuable complementary therapy for PD management.

  2. Cycling Therapy: Some research suggests cycling improves motor function in Parkinson’s patients.

    • Cycling therapy for Parkinson’s disease involves stationary or outdoor cycling to improve motor function, balance, strength, and cardiovascular health. Studies show that forced cycling (pedaling at a higher cadence, often assisted by a motor) enhances neuroplasticity and reduces symptoms like tremors, rigidity, and slowness. Regular cycling also boosts mood, cognitive function, and overall quality of life.

    • Pedaling for Parkinson’s is a structured exercise program based on research from the Cleveland Clinic. Participants cycle three times a week with a routine of a 10-minute warm-up at 60 RPM, 40 minutes at 80-90 RPM, and a 10-minute cool-down, resulting in up to a 35% reduction in symptoms. The program is available at many YMCAs, gyms, and community centers across the U.S., with both in-person and online classes. To find a class near you or to join an online session, visit the Davis Phinney Foundation’s Pedaling for Parkinson’s page.

Exercise is one of the best ways to delay Parkinson’s progression, with research showing that 150 minutes of moderate exercise per week can slow symptom advancement.

When seeking physical therapy for Parkinson’s disease, it’s recommended to choose clinics that specialize in PD treatment, particularly those offering LSVT BIG and Rock Steady Boxing programs, which are designed to improve movement, balance, and overall quality of life for individuals with PD.


5. Other Considerations: Supplements, Emerging Treatments, and Lifestyle Adjustments

Supplements That May Benefit Parkinson’s Patients

While research is still developing, some supplements show promise in supporting brain health and symptom management:

  • Ashwagandha: May reduce stress, improve sleep, and support cognitive function.
    • For more information, check out this systematic review which explores the potential of Withania somnifera (Ashwagandha) in treating neurodegenerative diseases, including Parkinson’s and Alzheimer’s. The plant’s bioactive compounds show promise in reducing oxidative stress, inflammation, and neuronal damage, while also promoting neuroprotection and regeneration. The review highlights Ashwagandha as a promising natural source for developing treatments for neurodegenerative disorders, though further clinical studies are needed. Read more here.
  • Coenzyme Q10 (CoQ10): A potential neuroprotective agent, though studies are inconclusive.
  • Creatine: Thought to support cellular energy production.
  • Vitamin D: Essential for bone health, as PD patients have a higher risk of osteoporosis.
  • Omega-3 Fatty Acids: May support brain function and reduce inflammation.

Important: Always consult a doctor before adding supplements to your regimen.

Exercises That Help Delay Symptoms

As mentioned above with respect to exercise and physical therapy, research suggests specific types of exercise are particularly effective for slowing Parkinson’s progression:

  • Aerobic exercises (e.g., walking, swimming) boost dopamine levels.
  • Strength training combats muscle stiffness and improves balance.
  • Agility drills and dual-task training (e.g., dancing, playing an instrument) enhance cognitive and motor function.
  • Stretching and flexibility exercises help reduce rigidity and maintain mobility.

Emerging Research and Future Treatments

Ongoing studies are exploring gene therapy, stem cell research, and gut microbiome connections to Parkinson’s. Neuroprotective drugs are also in development, aiming to slow disease progression rather than just treat symptoms.


6. Additional Reading: Preventing Future Cases

Ending Parkinson’s Disease: A Prescription for Action

A helpful book for understanding the broader factors driving the rise of Parkinson’s Disease, “Ending Parkinson’s Disease: A Prescription for Action” by Drs. Ray Dorsey, Todd Sherer, Michael Okun, and Bastiaan Bloem sheds light on the environmental, industrial, and systemic factors contributing to the rise of Parkinson’s. The book argues that Parkinson’s is not just a disease of aging but a preventable and treatable condition if we address known risk factors such as exposure to pesticides, heavy metals, and industrial chemicals.

Key takeaways from the book include:

  • The growing Parkinson’s epidemic and why cases are rising.
  • Environmental triggers such as pesticide exposure and industrial toxins.
  • How advocacy and policy changes can help prevent Parkinson’s.
  • Steps individuals and communities can take to fight back, from lobbying for cleaner environments to supporting research and patient care.

This book is both a call to action and a hopeful guide for those living with Parkinson’s and their caregivers. It emphasizes that while medical treatments exist, systemic change is necessary to reduce new cases and improve care for those affected.


Final Thoughts

Parkinson’s Disease is a complex condition, but early intervention with speech therapy, physical therapy, and exercise can significantly improve quality of life. Programs like LSVT LOUD and SPEAK OUT! help with both speech and swallowing difficulties, while LSVT BIG and other exercise therapies maintain mobility and delay progression.

For those seeking the best care, it is highly recommended that you reach out to a Parkinson’s Disease Center of Excellence for comprehensive treatment options.
