Parkinson’s disease is a chronic progressive ailment of the nervous system. Basal ganglia are a structure situated in the brain. The role of this is to produce and control all the voluntary movements and also to control the postural adjustments during these movements. Dysfunction of the basal ganglia leads to Parkinson’s disease. Tremors of the hand which are often known as pill rolling are the common manifestation seen in this disease.
Abnormalities of posture and balance, difficulty in imitating movement and rigidity in musculature offering resistance to the movement are some other common manifestations seen in Parkinson’s diseases. Levodopa is a common drug used for patients with this progressive movement disorder. The drug has the ability to cross the blood brain barrier and thus improve the function of the basal ganglia by raising the level of dopamine in it.
The main aim of physiotherapy is to make the patient functionally independent and minimise the complications arising from the ailment. Relaxation exercises are helpful in decreasing the rigidity of the muscles and overcoming stress. Some yoga and meditation can be effective in promoting relaxation as well. Audio tapes with soothing music also prove to be very effective.
Flexibility and stretching exercises are helpful in regaining joint range of motion. Also, passive positioning for long periods can improve flexibility of tightened structures. Patients with Parkinson’s disease are advised to lay on the stomach for long intervals with the head, shoulders and trunk flexed forward, thus helping stretch these particular muscles.
Physiotherapy for Parkinson’s Disease:
Passive and active movements are helpful in maintaining joint range of motion. The range of motion exercises emphasises on restoring the range of neck and trunk movement as these parts are mostly affected by the disease. Strengthening exercises are also encouraged for patients with Parkinson’s disease. They are presented a different walking pattern known as Parkinsonian gait, that is, they walk with short steps. Gait training plays a vital role in making them mobile. The goals of the gait training are to achieve the following:
• Improve stepping
• Improve arm swing
• Improve trunk movements
• Practice marching
• Improve length of the step while walking
• Encourage high stepping
• Encourage stepping forward
• Encourage stepping backwards
• Encourage stepping sideways
• Practice stopping, starting, changing direction and turning
Using visual and auditory cues help the patients take large steps and overcome initiation problems. Exercises on the Swiss ball can improve sitting balance. Gentle perturbations in standing and sitting, standing heel rises, toe raises, and single leg standing and marching can improve balance and postural stability for Parkinson’s patients. Those with Parkinson’s disease have a kyphotic posture that is, the upper trunk is bent forward and the chest musculature is very tight, which compromises the lung function.
Breathing exercise helps improve lung function and also help maintain lung capacity. Aerobic training also plays a very important role for Parkinson’s patients. Walking, jogging, swimming, climbing stairs, walking outdoors and stationary bicycling are some of the activities which can improve their aerobic endurance. Group exercises motivate patients and provide positive support. Exercises in the pool are also very helpful as they help build strength, flexibility and endurance. Thus, physiotherapy plays a major role in helping patients with Parkinson’s disease.
