A neurodegenerative disorder that affects predominately the dopamine-producing (“dopaminergic”) neurons in a specific area of the brain called substantia nigra.
These cells normally produce dopamine, a chemical (neurotransmitter) that transmits signals between areas in the brain that, when working normally, coordinate smooth and balanced muscle movement. Parkinson's disease causes these nerve cells to die, and as a result, body movements are affected.
In Parkinson’s, the cells of the substantia nigra start to die. When this happens, dopamine levels are reduced. When they have dropped 60 to 80 percent, symptoms of Parkinson’s start to appear.
Symptoms of Parkinson's Disease
Common symptoms of Parkinson's disease include:
1.Muscle rigidity
2.Tremors
3.Bradykinesia (the slowing down of movement and the gradual loss of spontaneous activity)
4.Changes in walking pattern and posture
5.Changes in speech and handwriting
6.Loss of balance and increased falls
7.Orthostatic hypotension (a drop in blood pressure when standing, resulting in lightheadedness or fainting)
Treatments for Parkinson’s disease
Although there is no cure for Parkinson’s disease, medicines, surgical treatment, and other therapies can often relieve some symptoms.
Medicines for Parkinson’s disease
Medicines can help treat the symptoms of Parkinson’s by:
Increasing the level of dopamine in the brain
Having an effect on other brain chemicals, such as neurotransmitters, which transfer information between brain cells
Helping control non-movement symptoms
The main therapy for Parkinson’s is levodopa. Nerve cells use levodopa to make dopamine to replenish the brain’s dwindling supply. Usually, people take levodopa along with another medication called carbidopa.
Therapies
Other therapies that may help manage Parkinson’s symptoms include:
Physical, occupational, and speech therapies, which may help with gait and voice disorders, tremors and rigidity, and decline in mental functions
A healthy diet to support overall wellness
Exercises to strengthen muscles and improve balance, flexibility, and coordination
Massage therapy to reduce tension
Yoga and tai chi to increase stretching and flexibility
GAIT
An abnormal stooped posture contribute to development of festinating gait ,characterized by a progressive increase in speed with a shortening of stride
Gait can be anteropulsive or retropulsive
Some patients are able to stop only when they come in contact with an object or a wall
Plantarflexion contracture leads to be walking and adds to postural in stability
EXERCISE TRAINING
RELAXATION EXERCISE
Gentle rocking to produce relaxation
PNF technique of rhythmic initiation
Relaxation audio tapes
FLEXIBILITY EXERCISE
Emphasize on active rom
traditional stretching technique
ROM exercise in physiological patterns of movements
STRENGTH TRAINING
Strengthening exercise are indicated for patients with primary muscle weakness and insufficient central activate of the motor unit as well as for disuse weakness associated with prolonged inactivity
FUCTIONAL TRAINING
Mobility in bed
Exercise in sitting posture tom improve pelvic mobility
