A multicenter, open-label study to assess subject QoL as reported by responders to long-term treatment fampridine-PR 10 mg twice daily. Subjects classified as non-responders (those who did not meet criteria for continued fampridine treatment in this study) at Week 4 will stop treatment but will continue to provide QoL data for comparative purposes.

Detailed Description:

This is a multicenter, open-label study to assess QoL as reported by responders to long-term treatment with prolonged-release fampridine 10 mg twice daily. This study has 2 components: a 4-week run-in period during which subjects are treated with prolonged-release fampridine and undergo subjective and objective assessments of walking ability, the results of which are used to determine who responded to study treatment, and an observational period, during which treatment responders will continue prolonged-release fampridine treatment. The subjects who do not meet the criteria to continue study treatment will be offered the opportunity to continue study participation but will not continue prolonged-release fampridine treatment.
