简要总结
The overall goal is to investigate the effectiveness of a novel intervention - Collagenase injection, for contracture management in patients with neurological impairments, such as stroke, brain injury, and spinal cord injury.

结局指标
主要结局
Change in spasticity as assessed by the Modified Ashworth Scale (MAS)
时间窗: Baseline before the intervention, follow up visits at 2 days (24 to 72 hours), 2 weeks, 1 month and 3 months post-injections
The Modified Ashworth Scale (MAS) evaluates the increase in muscle tone associated with upper motor neuron lesions. MAS scores will be recorded for the target muscle group(s) at each assessment time point.Scores range from 0 to 4, with an additional grade of 1+ between 1 and 2. Scores are defined as: 0 = no increase in muscle tone; 1 = slight increase in muscle tone with a catch and release or minimal resistance at the end of the range of motion; 1+ = slight increase in muscle tone with a catch followed by minimal resistance through less than half of the range of motion; 2 = more marked increase in muscle tone through most of the range of motion, but the affected part is easily moved; 3 = considerable increase in muscle tone, passive movement difficult; 4 = affected part rigid in flexion or extension.Lower MAS scores indicate reduced spasticity and improved muscle tone, whereas higher scores indicate greater spasticity.
Safety as assessed by the number of adverse events
时间窗: From baseline to end of study (3 months post-injections)
Adverse events include 1. Serious complications of XIAFLEX injection include tendon rupture, serious ligament damage, or skin laceration that may result in the inability to fully bend the joint and may require surgery to correct the complication. 2. XIAFLEX injection is likely to result in swelling, bruising, bleeding, and/or pain of the injected site and surrounding tissue.
次要结局
- Change in range of motion of target joints as assessed by the Passive Range of Motion (PROM)(Baseline before the intervention, follow up visits at 2 days (24 to 72 hours), 2 weeks, 1 month and 3 months post-injections)
- Change in range of motion of target joints as assessed by the Active Range of Motion (AROM)(Baseline before the intervention, follow up visits at 2 days (24 to 72 hours), 2 weeks, 1 month and 3 months post-injections)
