Assessment of Gait After Dysport Treatment
Video and Temporal Spatial Parameters Assessment of Gait After Dysport Treatment. A Pilot Study
Study Overview
Detailed Description
This is a prospective, single arm, non-randomized clinical study with pre-post assessment to include post-stroke and Traumatic Brain Injury (TBI) outpatients with spastic ankle / foot muscles amenable to botulinum toxin injection. Subjects must be able to walk without braces.
AbobotulinumtoxinA injection in a dose range of 500 to 1500 units one time to be distributed on the basis of clinical indication to ankle plantar flexors (gastrocnemius and soleus), knee extensors, knee flexors, tibialis posterior and long toe flexors.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Self-Selected Velocity (SSV)
Time Frame: Baseline, Follow-up (4-6 weeks)
|
Baseline and follow-up SSV with and without shoes.
Distance covers over time at self selected pace.
Larger value is better.
|
Baseline, Follow-up (4-6 weeks)
|
Maximal Velocity
Time Frame: Baseline, Follow-up (4-6 weeks)
|
Baseline and follow-up MV with and without shoes.
Distance covers over time when walking as fast as possible.
Larger value is better.
|
Baseline, Follow-up (4-6 weeks)
|
Step-length at Baseline and at Follow-up (Temporal-spatial Data)
Time Frame: Baseline, Follow-up (4-6 weeks)
|
Step length measured as the distance between the heel contact point of one foot and that of the other foot. Values are reported on the involved side. Larger values represent better outcome. |
Baseline, Follow-up (4-6 weeks)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Modified Ashworth Scale (MAS) at Baseline and at Follow-up
Time Frame: Baseline, Follow-up (4-6 weeks)
|
Passive range of ankle in 1 second with knee flexed and knee extended. Scale of 0-4 (0: no increase in muscle tone; 1: Slight increase in muscle tone, manifested by a catch and release or by minimal resistance at the end of the range of motion when the affected part(s) is moved in flexion or extension; 1+:Slight increase in muscle tone, manifested by a catch, followed by minimal resistance throughout the remainder (less than half) of the ROM (range of movement); 2: More marked increase in muscle tone through most of the ROM, but affect part(s) easily moved; 3: Considerable increase in muscle tone passive, movement difficult; 4: Affected part(s) rigid in flexion or extension. 0-4 (Min-Max) Higher scores represents increase abnormal tone. |
Baseline, Follow-up (4-6 weeks)
|
Tardieu Scale (TS) at Baseline and at Follow-up
Time Frame: Baseline, Follow-up (4-6 weeks)
|
Measurement of spastic response when passively ranging the ankle joint at very slow and very fast velocities with knee flexed and knee extended. Quality of muscle reaction (scored 0-4). 0 is no resistance to passive ROM to 4 indicating joint is immobile. |
Baseline, Follow-up (4-6 weeks)
|
Passive Range of Motion (PROM) at Baseline and at Follow-up
Time Frame: Baseline, Follow-up (4-6 weeks)
|
Normal ranges of ankle dorsiflexion 0 to 30 degrees with knee flexed.
Normal ranges of dorsiflexion 0 to 15 degrees with knee extended.
Higher values in dorsiflexion range represent a better outcome.

Baseline, Follow-up (4-6 weeks)
