Arms Assigned Interventions
Experimental: botulinum toxin Type A
Double-Blind Study Phase: On Day 1, botulinum toxin Type A 300 U will be given by intramuscular injections into specified muscles of the lower limb, and an optional dose of 100 U may be injected into additional lower limb muscles. Open Label Study Phase: Up to 3 treatments with botulinum toxin Type A up to 400 U will be given by intramuscular injections to the lower limb approximately every 12 weeks over a 42 week period.
Biological: botulinum toxin Type A
Double-Blind Study Phase: On Day 1, botulinum toxin Type A 300 U will be given by intramuscular injections into specified muscles of the lower limb, and an optional dose of 100 U may be injected into additional lower limb muscles. Open Label Study Phase: Up to 3 treatments with botulinum toxin Type A up to 400 U will be given by intramuscular injections to the lower limb approximately every 12 weeks over a 42 week period.
