Postpoliomyelitis Syndrome | A Randomized, Double Blind, Placebo Controlled Trial L-carnitine and Piracetam in the Treatment of Weakness, Muscle Fatigue and Muscle Pain in the Postpoliomyelitis Syndrome

Postpoliomyelitis Syndrome research study

What is the primary objective of this study?

This protocol aims to assess of L-carnitine and piracetam to relieve weakness, muscle fatigue and muscle pain in patients with Postpoliomyelitis Syndrome.

Who is eligible to participate?
