Exercise Physiology And Parkinson’s Disease

Parkinson’s disease is a progressive neurological condition that affects movement, balance, coordination and, often, mood and thinking. While there is currently no cure, there is strong evidence that targeted exercise can significantly improve function, independence and quality of life.

How Exercise Helps In Parkinson’s

 

Parkinson’s typically involves:

• Slowness of movement (bradykinesia)
• Rigidity or stiffness
• Tremor
• Postural instability and falls risk
• Changes in gait (shuffling, reduced arm swing, freezing)
• Fatigue, mood changes and sleep problems

 

Exercise doesn’t stop the condition, but research shows it can:

• Improve gait speed, stride length and balance
• Enhance muscle strength and cardiovascular fitness
• Reduce falls risk
• Support mood and cognitive function
• Help manage constipation and sleep through general activity benefits

 

High-effort, targeted exercise — especially if started early — is increasingly encouraged in Parkinson’s management guidelines.

What An Exercise Physiologist Does For Parkinson’s

 

An Accredited Exercise Physiologist will:

• Take a detailed medical and medication history and understand your neurologist’s plan.
• Assess gait, balance, strength, flexibility, cardiovascular fitness and functional tasks (e.g., sit-to-stand, turning, dual-task walking).
• Identify your personal goals—from walking safely in the community to staying active with grandkids or continuing sports.

 

Programs typically include:

• Strength training: Lower and upper body exercises to maintain power and independence (e.g., squats, step-ups, rows, presses).
• Balance and agility drills: Stepping in different directions, turning practice, perturbation training, and dual-task walking.
• Gait training: Focusing on longer steps, arm swing, and overcoming freezing episodes with visual/auditory cues.
• Aerobic training: Walking, cycling or other preferred modes to boost fitness and brain health.

 

Where Photobiomodulation May Fit

Photobiomodulation (PBM) refers to the use of specific wavelengths of light (often red or near-infrared) applied to the body with the aim of influencing cellular processes. It is being actively researched in several neurological conditions, including Parkinson’s disease.

Sydney Injury Specialists is affiliated with Artarmon Physiotherapy, where we are involved in ongoing research into PBM for Parkinson’s, and you are available there on Friday afternoons. While PBM remains an emerging therapy, early research suggests it may:

• Influence cellular energy production (mitochondria)
• Modulate inflammation and oxidative stress
• Potentially support brain and nervous system function

 

It’s important to be clear: PBM is not yet standard care, and more high-quality research is needed to fully understand its effects. However, participating in supervised research programs may provide access to promising interventions under careful monitoring.

How We Integrate Exercise And PBM

 

Rather than viewing exercise and photobiomodulation as either/or, we look at them as potentially complementary approaches:

• Exercise physiology is a core, evidence-backed pillar—focusing on strength, balance, aerobic fitness and mobility.
• Photobiomodulation research at Artarmon offers a chance to engage with cutting-edge therapy under a structured protocol.

For suitable clients, your week might look like:

• Regular EP-led exercise sessions at Sydney Injury Specialists (or home/park-based programs).
• Friday afternoon visits to Artarmon Physiotherapy for PBM research sessions and review, if you are enrolled in the study.
• Ongoing communication between your EP, neurologist and other health professionals.

 

Key Takeaways

 

• Exercise physiology plays a central role in managing Parkinson’s symptoms and maintaining independence.
• Programs focus on strength, balance, gait and cardiovascular fitness, tailored to your stage and goals.
• Photobiomodulation is a promising, but still emerging, therapy; your involvement in research at Artarmon Physiotherapy means clients can discuss whether participation is appropriate for them.
• If you or a loved one has Parkinson’s, structured EP-led exercise — with optional PBM research involvement — can form a comprehensive, hopeful approach.
