Outcomes
Primary outcome [1] 269327 0
Six-minute walk test: a validated measure that has been used to assess functional capacity in neuromuscular disease (ATS Committee on Proficiency Standards for Clinical Pulmonary Function Laboratories 2002; Kierkegaard & Tollback 2007; McDonald et al 2010). In this setting, it is viewed as a measure of activity-dependent fatigue in patients with demyelinating disease (Goldman et al 2008).

Secondary outcome [1] 279380 0
Peripheral nerve excitability measurement (composite score of hyperpolarizing threshold electrotonus at 90-100ms, late subexcitability, refractoriness and superexcitability), including pre/post voluntary contraction studies.

Summary
Brief summary
The purpose is to investigate whether treatment with the medication, fampridine, can help improve the ability to function in patients who have chronic inflammatory demyelinating polyneuropathy (CIDP).

Who is this for?
You are eligible to participate in this study if you are ages between 18-80, have CIDP and currently suffer from fatigue and a decreased functional ability.

Trial detials
In this studywith patients will receiving 12 weeks of Fampridine (active drug) at a dose of 10mg oral tablet twice daily, and 12 weeks of placebo (sham) treatment consisting of lacotse tablets, separated by a 4-week washout period.
During the trial, participants will not know if they are receiving active drug or the placebo.

Participants will be assessed at basline foloowed by 4 weekly intervals to measure fatigue, functional ability and nerve function.
