Parkinson's Disease: Symptoms, Stages & Treatment

Parkinson's disease affects slowness of movement and the ability to initiate and perform intentional movements, and can also affect communication, sleep, mood and everyday activities. Rehabilitation supports function through an individual plan; it does not replace medical care or promise to stop the disease.

Understanding the condition

What is Parkinson's disease?

Parkinson’s is a nerve condition that slowly gets worse over time. It happens when the brain gradually loses the cells that make dopamine, the chemical that helps control smooth movement. That can affect how you move and many parts of daily life.
The signs are different for everyone. Some people notice slowness or stiff muscles first. Others get a shaky hand (tremor) or feel less steady on their feet. There can be other changes too, like poor sleep, low mood, constipation or a weaker sense of smell. Sometimes these show up years before the movement problems do.
Treatment is planned with your neurologist and usually includes medicines. Rehab works alongside that. At our Parkinson’s rehabilitation centre in Kolkata, we focus on what matters to you, like walking safely, getting dressed or speaking clearly, so you can stay active and independent for longer.

Stages of Parkinson's disease

Staging of Parkinson's disease uses the Hoehn & Yahr scale. At Rehabana, we assess each patient's disease severity and movement difficulties using this scale.

Unfortunately, most patients visit Rehabana at Stage 3 or Stage 4 because of poor awareness. Early detection and rehabilitation can help preserve independence for a longer period.

  • Stage 0: No sign of disease
  • Stage 1: Unilateral symptoms only
  • Stage 1.5: Unilateral and axial involvement
  • Stage 2: Bilateral symptoms, no impairment of balance
  • Stage 2.5: Mild bilateral disease with recovery on pull test
  • Stage 3: Mild to moderate bilateral disease, some postural instability, physically independent
  • Stage 4: Severe disability, still able to walk or stand unassisted
  • Stage 5: Wheelchair bound or bedridden unless aided

Symptoms

Symptoms and non-motor changes

Parkinson's symptoms differ from person to person and can change over time.

Movement changes may include slowness, stiffness, tremor, freezing of gait, smaller steps, difficulty starting a step or turning, and changes in standing balance. Some people also notice softer speech, reduced facial expression, handwriting changes or difficulty with hand movements.

Non-motor symptoms may involve sleep, mood, thinking, bowel or bladder function, pain, fatigue or other concerns. Tell the care team about changes, even when they do not seem connected to movement.

Parkinson’s Problem

Problems that can affect everyday life

Everyday problems Parkinson’s can cause

A symptom becomes a practical problem when it makes an important activity harder, less safe or less comfortable.

Rehabana has observed that a person might find it harder to get out of bed or a chair, turn in a narrow space, dress, prepare a meal, write, join a conversation or swallow comfortably. The same symptom can affect people differently depending on their routines, home, work and support.

Not every difficulty needs the same therapy. A conversation with the person and their care team can identify which challenges deserve attention first.

Functional impact and personal priorities

Daily function and personal priorities in Parkinson’s

Rehabilitation starts with what the person wants or needs to do in daily life.
Rehabana first identifies the problems, such as changes in bed mobility (for example, moving from lying on the back to the side, or rolling), standing with or without support, transfers, walking speed, standing and walking balance, hand use, speech or energy, that can affect independence, increase agitation, and limit social participation, work, hobbies and confidence. Family members may notice changes too, but the person's own priorities should guide the plan.

Examples of goals might include moving around the home more confidently, making dressing easier, being understood in conversation or discussing swallowing concerns with a clinician. Goals should be specific, meaningful and reviewed together.

Rehabana's step-by-step rehabilitation goals

How rehabilitation can help in Parkinson’s

Parkinson’s disease rehabilitation fits therapy to each person. We look at their symptoms and abilities, and what they’re aiming for.One clear goal at a time, each about something the patient can really do in daily life.

  • Moving around in bed more easily
  • Being able to stand up from sitting
  • Getting from bed to chair and back again more easily
  • Steadier balance when standing still and when moving (static and dynamic)
  • Walking, with or without a walking aid
  • Better walking (gait), with reminders to take bigger steps (big-step cueing) and practice walking while doing something else (dual-task training)
  • Walking safely on their own outside the home, as far as the patient is able.
Rehabana's assessment and rehabilitation planning process

Assessment

Rehabana's assessment and rehabilitation planning process

An assessment helps the rehabilitation team understand current function and the person's priorities.

First, our doctor takes the patient's basic history, medical history and any history of falls to identify potential risks and plan an appropriate rehabilitation programme. Next, our multidisciplinary therapy team conducts a detailed assessment using standardised tools.

The findings help our team set individualised rehabilitation goals, decide the next steps in the programme, and monitor progress through regular reassessment and ongoing therapy.

  • Physical ability: Timed Up and Go (TUG), Berg Balance Scale (BBS) and Five Times Sit-to-Stand Test (5xSTS)
  • Functional ability: Functional Independence Measure (FIM) and Nine-Hole Peg Test (9HPT)
  • Cognitive ability: Montreal Cognitive Assessment (MoCA)
  • Swallowing ability: Gugging Swallowing Screen (GUSS)
Agreeing what matters

Baseline goals

Agreeing what matters

Baseline goals turn assessment findings into practical, shared priorities.
The person and clinician can agree on a small number of goals tied to daily life, such as practising a safer transfer strategy or making a chosen activity more manageable. Goals should reflect current ability, preferences and relevant clinical advice.

We do not focus only on baseline goals; we also aim to prevent further injuries and complications through appropriate rehabilitation.

Treatment Plan Around The Person

Interventions

A plan shaped around the person

Interventions may combine guided practice, education and strategies for everyday activities.

Our physiotherapy team may address movement, walking or balance; our occupational therapy team may explore task changes, routines or the environment; our speech and language therapy team may address communication or swallowing after assessment; and our psychology team may address poor cognition and aggressive behaviour. A plan can include practice between visits when a clinician considers it suitable.

Robotic rehabilitation or other equipment may be relevant only for selected people and goals. Ask the treating team what a service includes, who it may suit and what evidence supports it.

Reassessment

Checking and adjusting

Reassessment helps the team review progress, new difficulties and whether the plan still fits.

Before each follow-up, our multidisciplinary team discusses the patient's progress, remaining impairments and unmet goals, then reassesses the patient and sets new rehabilitation goals. At follow-up, the person and clinician can revisit goals, discuss what is helping or difficult, and decide whether to continue, adjust or seek another opinion.

Parkinson's symptoms and life circumstances can change, so plans may need to change too. The timing of reviews depends on clinical need and the service plan.

Outcomes

Meaningful changes in daily life

Useful outcomes are changes that matter to the person, measured in ways agreed with the care team.

Outcomes may relate to a goal, such as completing a chosen task with a strategy or taking part in an activity. Progress can look different for each person and may include maintaining a skill, adapting an activity or identifying a new support need.

Review and coordination of care

Coordinated care

Review and coordination of care

Parkinson's rehabilitation works best as part of coordinated care that reflects changing needs.

The person may discuss rehabilitation with their neurologist or other treating clinician, especially when symptoms change or new concerns arise. With the person's agreement, rehabilitation professionals can share relevant observations with the wider care team.

Medication decisions and diagnosis belong with qualified medical professionals. Rehabilitation recommendations should be coordinated with the person's clinical advice.

Caregivers

Caregiver support

Caregivers can support daily routines while also sharing observations and looking after their own wellbeing.

A family member or care partner may help communicate priorities, notice changes and practise agreed strategies. Their role should be discussed with the person and care team, respecting the person's preferences and independence.

If caregiving feels difficult, ask the care team about practical support, education and local resources. Support needs can change as the condition and family circumstances change.
