Hypothesis
The formulation of hypotheses is one of the key steps in the scientific method.
Hypotheses are usually tested using experiments and are usually accepted or rejected depending on the outcome of the experiments.
If a hypothesis is rejected, it does not mean that the entire subject is abandoned. Rather, new hypotheses may be formed and experiments conducted to further explore the subject.

Spastic paralysis refers to a prolonged pathological situation in which the muscles are influenced by continuous spasms and overstated tendon reflexes due to destruction of the central nervous system.
The condition is a side effect of paralysis, which fluctuates from mild or extreme muscle stiffness, uncontrollable leg motions. It may take place in combination with multiple sclerosis, spinal cord injury, brain trauma, or cerebral palsy.
