*4.2.1. Pressure stimulation*

When air pressure in a splint is applied to soleus muscle of the lower limb in people with SCI, alpha motor neuron reflex excitability is suppressed (Robichaud et al., 1992).

#### *4.2.2. Therapeutic massage*

When people with SCI were given massage treatment for 3 minutes, there was a de‐ crease in the amplitude of H-reflex when compared with what it was before the massage (Goldberg et al., 1994).

#### *4.2.3. Whole Body Vibration (WBV)*

When WBV is applied on a person with SCI, residual effects of medication for muscle spasticity will sometimes be recognized. And because the duration of stimulation differs among researchers, a simple comparison is difficult (Ness et al., 2009).

There is a report in which the adopted cycle of WBV treatment consists of the following: 4 bouts of 45 seconds with one minute of seated rest between bouts, done on 3 days a week lasting for 4 weeks.

#### **4.3. In people with Parkinson's disease**

Parkinson's disease (PD), often caused by depletion of dopamine in the substantia nigra of the midbrain, is a disease that indicates a variety of movement disorders. Rigidity, tremor, akinesia, amimia, and pill-rolling phenomenon are the characteristic symptoms. By taking Ldopa, people with PD can alleviate these symptoms.
