| MAS(Modified Ashworth Scale)of wrist flexor | 4 weeks | Change from baseline at week 4 for wrist flexor muscle tone as measured on the MAS(Modified Ashworth Scale) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| MAS(modified Ashworth Score)of elbow and finger flexor | 4 weeks after injection | Change from baseline at week 4 for elbow flexor and finger flexor muscle tone as measured on MAS |
| MAS(modified Ashworth Score)of wrist, elbow and finger flexor | 8, 12 weeks after injection | Change from baseline at week 8, 12 for wrist flexor, elbow flexor and finger flexor muscle tone as measured on MAS |
| Percentage of treatment responder at week 4, 8, 12 after injection | 4, 8, 12 weeks after injection | A treatment response is defined as 1-point improvement on the MAS of injection site |
