Parkinson’s disease is a progressive neurological condition in which the brain slowly loses dopamine-producing cells, causing tremor, stiffness, slowed movement and balance loss. It usually begins after age 60. Physical therapy can help people walk more safely, lower fall risk and stay independent longer. SportsMed Physical Therapy provides neurological rehabilitation at New Jersey and Connecticut locations.
What Is Parkinson’s Disease?
Parkinson’s disease is a disorder of the substantia nigra, a small brain region that produces dopamine. Dopamine helps the basal ganglia scale and sequence movement, so as those cells are lost, movements become smaller, slower and harder to start. The four cardinal signs are resting tremor, rigidity, bradykinesia, meaning slowness of movement, and postural instability. Nearly one million people in the United States live with Parkinson’s, and about 90,000 are diagnosed each year. Most are over 60, though roughly one in ten cases begins before 50. Parkinson’s also affects handwriting, voice volume, sleep and mood.
What Causes Parkinson’s Disease?
In most cases there is no single identifiable cause. Researchers describe it as a mix of genetic susceptibility and environmental exposure, with abnormal clumping of a protein called alpha-synuclein inside nerve cells. About 10 to 15 percent have a family history. Age is the strongest single factor, and men are diagnosed more often.
Recognized risk factors include:
- Increasing age, especially after 60
- A parent or sibling with Parkinson’s disease
- Gene variants such as LRRK2, GBA or PARK7
- Long-term occupational exposure to certain pesticides or herbicides
- Repeated head injuries, including sport-related concussions
What Are the Symptoms of Parkinson’s Disease?
Symptoms usually begin on one side and stay asymmetric for years. Many people notice changed handwriting, a dragging foot or reduced arm swing before tremor appears.
Common symptoms include:
- Resting tremor, often starting in one hand or thumb
- Rigidity and a stiff feeling in the limbs or trunk
- Slow, small movements, including shuffling steps and reduced arm swing
- Stooped posture and difficulty turning or rising from a chair
- Freezing of gait, where the feet feel stuck in doorways or turns
Seek prompt medical attention if you have a fall with a head strike, a rapid change in walking or thinking, fainting, or new severe symptoms after a medication change.
How Is Parkinson’s Disease Diagnosed?
Parkinson’s is diagnosed clinically by a neurologist or movement disorder specialist. No blood test confirms it. The diagnosis requires bradykinesia plus either resting tremor or rigidity, along with a supportive response to dopaminergic medication. MRI or a DaTscan may be used to rule out other causes of tremor or gait change. Physical therapists do not diagnose the disease, but our evaluation measures walking speed, stride length, turning time, balance confidence and fall history. Those baseline numbers guide the plan and show whether therapy is working.
How Physical Therapy Treats Parkinson’s Disease
Exercise is one of the few interventions consistently linked with better mobility and quality of life in Parkinson’s. The nervous system under-scales movement in Parkinson’s, so therapy uses large amplitude practice, external cues such as metronomes, floor lines or counting, and high-effort exercise to restore normal-sized, well-timed movement.
At SportsMed, care blends vestibular therapy and neurological rehabilitation with dedicated gait and balance training. Sessions include big reaching and stepping drills, posture work, sit-to-stand practice, dual-task training, and strategies for turning and doorway freezing. Alter-G anti-gravity treadmill work helps people practice longer strides safely, and caregiver training rounds out the plan.

How Long Does Recovery Take?
Parkinson’s is lifelong, so therapy works best in episodes rather than one course. A typical block runs six to twelve weeks, two to three times a week, followed by an independent home program. Many people return for a tune-up every six to twelve months, or sooner after a fall or a medication change. Progress comes faster when exercise happens most days, when sessions are scheduled during medication “on” periods, and when a family member learns the home program too.

Frequently Asked Questions About Parkinson’s Disease
Q: Can physical therapy slow Parkinson’s disease?
A: Therapy does not cure or reverse Parkinson’s, but research consistently links regular, vigorous exercise with better walking speed, balance and quality of life. Physical therapy teaches the movement strategies and exercise intensity that help many people stay active and independent longer.
Q: When should someone with Parkinson’s start therapy?
A: As soon after diagnosis as possible, even when symptoms feel mild. Early therapy sets baseline measurements, builds an exercise habit while it is easier to learn, and addresses subtle balance changes before falls begin. Waiting until walking is clearly impaired makes progress slower.
A: Most knee and hip replacement patients attend two to three sessions per week for six to twelve weeks, then taper as goals are met. The number depends on your strength, the joint replaced and your surgeon’s protocol. Home exercise matters as much as clinic time.
Q: What is freezing of gait, and can therapy help?
A: Freezing is a sudden sense that the feet are glued to the floor, often in doorways, turns or crowded spaces. Physical therapy teaches cueing strategies such as counting, stepping to a beat or stepping over a line, which help many people restart movement safely.
Q: How often should I exercise between sessions?
A: Most guidelines encourage activity on most days of the week, combining aerobic exercise, strengthening and balance work. Your therapist sets a home program and intensity that match your stage and other health conditions. Consistency across the week matters more than one long session.
Q: Can therapy happen at home instead of a clinic?
A: Yes. SportsMed offers in-home physical therapy for patients who cannot travel safely. Home visits also let the therapist address real obstacles such as stairs, thresholds, bathroom transfers and rug edges, which is often more useful than clinic-only care in later stages.
Q: Do I need a referral, and is there a clinic near me?
A: Many patients begin without a referral, though some insurance plans require one and your neurologist may prefer to coordinate care. We have clinics across Ocean, Passaic and Union Counties, including Toms River, Brick, Clifton, Wayne, Union, Linden and Elizabeth.
Movement is one of the most valuable tools in Parkinson’s care, and it works best with guidance. A SportsMed therapist can measure your walking and balance, set the right exercise intensity, and teach your family to support it.
