- Minimum 6 months post injury/insult with unilateral upper limb spasticity of the elbow, wrist and/or finger flexors.
- Preinjection Modified Ashworth scores \> 2 in at least one of the following areas: elbow, wrist, or finger flexors.
- Subjects must meet criteria for CMA Hand Impairment Scale Stage 2 and be able to complete Task 3 (thumb to index finger) of the CMA Hand Impairment Scale Stage 3, or demonstrate 50% gross grasp to be included.

- Able to answer reliably to yes/no questions.
- Able to follow reliably 1-step instructions.

- Females who are pregnant, breast-feeding, or planning a pregnancy during the study or who think that they may be pregnant at the start of the study, or females of childbearing potential who are unable or unwilling to use a reliable form of contraception during the study.
- Concurrent participation in another investigational drug or device study or participation in the 30 days immediately prior to study enrollment.
- Treatment with botulinum toxin of any serotype for any reason in less than 3 months prior to initial date of injection for the study.
- Any medical condition that may put the subject at increased risk with exposure to botulinum toxin type A including diagnosed myasthenia gravis, Eaton-Lambert syndrome, amyotrophic lateral sclerosis, or any other disorder that might interfere with neuromuscular function.
- Evidence of recent alcohol or drug abuse.
- Infection or skin disorder at an anticipated injection and/or electrical stimulation sites.
- Any condition or situation that, in the investigator's opinion, may put the subject at significant risk, confound the study results, or interfere significantly with the subject's participation in the study.
- Use of aminoglycoside antibiotics, curare like agents, or other agents that might interfere with neuromuscular function.
- Individuals with a cardiac pacemaker, a defibrillator, or baclofen pump.
- Individuals with an unhealed or healing fracture or dislocation in the arm to be evaluated.
