SHARING FINDINGS ABOUT PARKINSON'S DISEASE

It is not necessary that every patient with PD possesses the same set of symptoms at different severity levels. But falling patterns somehow can be same either forward, side, backward. As such patients have a unique set of symptoms and this may trigger some researchers to work on Freezing of Gait (FoG) for fall detection or fall risk assessment. I t is also to be noted that patients with PD lose their balance control and are more likely to fall. During experimentation and measurement, it is observed that falling might be more likely to happen during turning. There does not exist an exact technical device to detection FoG. Treating FoG can be done by involving brain to perform multiple actions such as singing, marching, ordering like get -set-go, etc. This deceiving therapy to the brain helps somehow for patients to unfreeze.

Wearing accelerometers on chest position gives unnecessary noise data as compared to waist or hip. So waist is considered good position to monitor patient gait. As citizens at age 70+ are likely get ill soon or fall, so naturally there is a need to work on this group of people for their well-being.

The patients with PD at later stages of disease may have to undergo with Deep Brain Stimulation. Problem with DBS is that it cannot decrease the progression of the disease. Other side effects of DBS may be brain bleeding, cognition decline, strokes, infection and minor symptoms of disease may last. However, DBS can relieve some symptoms and enhance wellness up to five years after surgery.

Gastroparesis is one such symptom in which food stays in the stomach for more than two hours. Mediterranean diet can be introduced in the patients with PD.

Symptoms of tremor or Bradykinesia may progress faster than rigidity.

The loss of balance or postural instability cannot be treated with medicine. MATLAB tool has proved to be very efficient in dealing with calculations related to signals from the SHIMMER. So it is a signal processing tool which can easily be employed in such applications where there is a requirement to capture and track the real time motion as data acquisition. A 4-Meter Go & Back (4GB) scale has been designed and tested. This test may be good in planning and taking the measurements necessary for experiment. The different type of gaits, gait parameters and instructions are also provided in the test. Wearing accelerometers on the chest shows higher acceleration during gait analysis and unnecessary body motion create more noise in the calibrated signals. Also, if a patient initiates steps with energy, his/her gait may become more stable. From our visual examination and post processing analysis, results show that after DBS surgical procedure, the patient is still experiencing postural instability even she falls suddenly showing no sign specially when medication is not taken in time. So it is evident that such patients may have reduced cognition even after surgery.
