Outcomes

Primary Outcomes

Change from baseline in Modified Ashworth Scale score of Wrist Flexor

The Modified Ashworth Scale (MAS), a clinical scale used to assess muscle spasticity, was administered with the subject placed in a supine position. The investigator performing the assessment was required to be adequately trained and familiar with the MAS grading criteria, and the same evaluator was used throughout the clinical study whenever possible.

Time frame: Week 4, Week 8, Week 12

Change from baseline in Modified Ashworth Scale score of Elbow Flexor, Finger Flexor

Time frame: Week 4, Week 8, Week 12

Proportion of subjects with at least 1-point improvement from baseline in the Modified Ashworth Scale score for the Wrist Flexor, Elbow Flexor, Finger Flexor

Time frame: Week 4, Week 8, Week 12

Changes from baseline in Disability Assessment Scale score

The Disability Assessment Scale (DAS) was evaluated by the investigator through an interview with the subject. The assessment was performed by the same investigator throughout the clinical study whenever possible to assess Hygiene, Dressing, Limb Position, and Pain.

Time frame: Week 4, Week 8, Week 12

Global Assessment Scale evaluated by investigator

The overall improvement in muscle stiffness was assessed using the Global Assessment Scale (GAS) by both the investigator and the subject at Weeks 4, 8, and 12 after administration of the investigational product.
