BACKGROUND INFORMATION  
Post-stroke, ~40% of patients develop spasticity, with severe or disabling spasticity in up to 
15% of patients. 1, 2 Of those who have sustained a traumatic brain injury, approximately 75% develop 
spasticity, with nearly 50% warranting anti-spasticity treatment. 3 Spasticity is a chronic condition 
defined as “disordered sensory-motor control, resulting from an upper motor neuron lesion, presenting 
as intermittent or sustained involuntary activation of muscles” with postural limb changes. 4 Spasticity is 
characterized by muscle stiffness, paresis, muscle spasms, muscle fatigue, and in some cases rheological 
change with abnormal lower limb postures. 5 Beyond the underlying primary disorder and disease, 
spasticity negatively influences patient function, quality of life and increases caregiver burden. 6 
 
Hemiparesis from acquired brain injury can also impair mobility, related to abnormal passive and active 
antagonist muscle resistance. 4  In chronic hemiparesis, walking speed stabilizes at a low plateau level, in 
most cases inadequate to sustain community ambulation. 7 Intramuscular injection of botulinum toxin 
type A (BoNT-A), produces muscle relaxation for 12–16 weeks or longer and is an effective treatment for 
lower limb muscle overactivity in spastic paresis. 8 While botulinum toxin reduces muscle tone and 
improves spasticity-related features in lower-limb muscles, muscle selection that results in improved 
walking outcomes have not been explored. 8 
 
Currently clinical evaluation of the patient with lower limb spasticity after TBI or stroke focuses primarily 
on physical examination, and in some instances visual assessment of walking. These data, supplemented 
by registries, illustrations depicting typical patterns, and the potential muscles involved are used to 
determine the selection of the potential muscles for the injection of botulinum toxin.  
 
This pilot study will aim to understand the potential benefit of the assessment of walking using video 
slow motion for the muscle selection and develop an image catalogue of the potential results of 
injection of abobotulinumtoxinA by comparing foot postures before and after injection.  
 
1.1 Rationale 
Current FDA approved dosing for leg muscle injection with abobotulinumtoxina ranges from 1000 to 
1500 units to be distributed based on clinical indication to ankle plantar flexors (gastrocnemius and 
soleus), tibialis posterior and long toe flexors at intervals greater than 3 months. The treatment 
algorythm may be improved by a dynamic walking visual guidance. We believe visual assessment will 
improve guidance to muscle selction for treatment, which may result in improvement in foot posture 
and walking.  
1.2 Potential Risks and Benefits 
1.2.1 Potential Risks 
Lower limb spasticity injection most frequently reported adverse reactions (>2%) are: nasopharyngitis, 
muscular weakness, musculoskeletal pain, dizziness and falls.

1.2.2 Potential Benefits 
Potential benefits of visual assessment during walking may improve functional outcomes. While it may 
not provide direct benefit to subjects, the importance of the knowledge that may result from the study 
such as improvement in muscle selection for treatment, patient outcomes and patient satisfaction.

7 STUDY PROCEDURES /EVALUATIONS 
7.1 Study Procedures/Evaluations 
 
Primary Evaluations:  
SSV without and with shoes – Subjects will be advised to walk 10 meters with and without their shoes at 
their comfortable walking speed. Three trials of this test will be collected. SSV will be obtained prior to 
the study treatment at baseline and follow-up visits.  
MV without and with shoes – Subjects will be advised to walk 10 meters with and without their shoes 
and their fastest walking speed. Three trials of this test will be collected. MV will be obtained prior to 
the study treatment at baseline and follow-up visits.  
Secondary Evaluations: 
Tone will be measured for the gastrocnemius and soleus muscles with the MAS – MAS will be used to 
assess muscle tone in the grastrocnemius and soleus muscles prior to the study treatment at baseline 
and at the follow up visit.  
 
Spasticity in the gastrocnemius and soleus muscles measured with the TS - The will be used to assess 
spasticity in these muscles. Assessments will be made at slow (V1) and fast (V3) speed of stretch. The 
angle of arrest at slow speed (Xv1), the angle of catch at fast speed (Xv3) and the spasticity grade (Y) at 
fast speed will be recorded in the eCRF at each speed. The spasticity angle will be calculated by the 
difference between the angle of arrest at slow speed (XV1) and the angle of each at fast speed (Xv3). The 
TS ratings will be obtained prior to the study treatment at baseline and at the follow-up visit.  
 
PROM - will be used to assess treatment response. The ankle, knee flexed and knee extended 
measurements will be obtained prior to the study treatment at baseline and at the follow-up visit.

8.1 Adverse Events 
An adverse event is any untoward or unfavorable medical occurrence in a human subject, including any 
abnormal sign (for example, abnormal physical exam or laboratory finding), symptom, or disease, 
temporally associated with the subject’s participation in the research, whether or not considered 
related to the subject’s participation in the research. 
8.2 Serious Adverse Events 
A serious adverse event (SAE) is one that meets one or more of the following criteria: 
 
Results in death 
 
Is life-threatening (places the subject at immediate risk of death from the event as it occurred) 
 
Results in inpatient hospitalization or prolongation of existing hospitalization 
 
Results in a persistent or significant disability or incapacity 
 
Results in a congenital anomaly or birth defect   
 
An important medical event that may not result in death, be life threatening, or require 
hospitalization may be considered an SAE when, based upon appropriate medical judgment, the 
event may jeopardize the subject and may require medical or surgical intervention to prevent 
one of the outcomes listed in this definition. 
8.3 Time Period and Frequency for Event Assessment and Follow-Up 
Unanticipated problems will be recorded in the data collection system throughout the study.  
The PI will record all reportable events with start dates occurring any time after informed consent is 
obtained until 7 (for non-serious AEs) or 30 days (for SAEs) after the last day of study participation.  At 
each study visit, the investigator will inquire about the occurrence of AE/SAEs since the last visit.  Events 
will be followed for outcome information until resolution or stabilization. SAEs will be reported to 
DrugSafety.USA@ipsen.com.  
8.4 Characteristics of an Adverse Event 
8.4.1 
Relationship to Study Intervention 
To assess relationship of an event to study intervention, the following guidelines are used: 
1. Related (Possible, Probable, Definite) 
a. The event is known to occur with the study intervention.

d. The event reappears upon a re-challenge with the intervention. 
2. Not Related (Unlikely, Not Related) 
a. There is no temporal relationship between the intervention and event onset. 
b. An alternate etiology has been established. 
8.4.2 
Expectedness of SAEs 
The Study PI will be responsible for determining whether an SAE is expected or unexpected.  An adverse 
event will be considered unexpected if the nature, severity, or frequency of the event is not consistent 
with the risk information previously described for the intervention.   
8.4.3 
Severity of Event 
The following scale will be used to grade adverse events: 
1. Mild: no intervention required; no impact on activities of daily living (ADL) 
2. Moderate: minimal, local, or non-invasive intervention indicated; moderate impact on ADL 
3. Severe: significant symptoms requiring invasive intervention; subject seeks medical attention, 
needs major assistance with ADL 
9   STATISTICAL CONSIDERATIONS 
9.1 Study Hypotheses 
The statistical analysis of the data obtained from this study will be performed using SPSS v. 19.0.  
All data collected in this study will be documented using summary tables and subject data listings. 
Continuous variables will be summarized using descriptive statistics, specifically the mean, median, 
standard deviation, minimum and maximum. Categorical variables will be summarized by frequencies 
and percentages. 
Demographics, Medical History and Baseline Characteristics: 
The subjects will be summarized with respect to baseline demographics and baseline characteristics 
(e.g., age, gender, race, ethnicity, injury type and time since last injury, height and weight, etc.). These 
will be summarized by descriptive statistics including means, medians, standard deviations and ranges 
(for quantitative variables) and counts and percentages (for categorical variables). 
 
Primary Endpoint:   
The primary end point is to collect SSV and MV with and without shoes at Baseline and Follow-up Visits 
using the Gait Mat. Data will be reported descriptively and continuous data will be reported with the 
change from follow-up to baseline.  
Secondary Endpoint:  
The following are secondary endpoints:

 
PROM will be presented descriptively as continuous data along with the change form baseline.  
 
The TS will be presented descriptively as continuous data along with the change from baseline.  
 
The MAS will be presented descriptively as rank data along with the change from baseline.  
9.2  Sample Size  
For this pilot study, no prospective calculations of statistical power have been made. The sample size of 
15 subjects has been selected to provide information on safety, reliability and feasibility of video 
assisted muscle selection for Dysport injection.  
10     SOURCE DOCUMENTS AND ACCESS TO SOURCE DATA/DOCUMENTS 
Study staff will maintain appropriate medical and research records for this study, in compliance with IRB 
requirements for the protection of confidentiality of subjects.  Study staff will permit authorized 
representatives of the IRB to examine (and when required by applicable law, to copy) research records 
for the purposes of quality assurance reviews, audits, and evaluation of the study safety, progress and 
data validity.   
11 
  ETHICS/PROTECTION OF HUMAN SUBJECTS 
11.1 Ethical Standard 
The investigator will ensure that this study is conducted in full conformity with the principles set forth in 
The Belmont Report: Ethical Principles and Guidelines for the Protection of Human Subjects of Research, 
as drafted by the US National Commission for the Protection of Human Subjects of Biomedical and 
Behavioral Research (April 18, 1979) and codified in 45 CFR Part 46 and/or the ICH E6. 
11.2  Institutional Review Board 
The protocol, informed consent form(s), recruitment materials, and all subject materials will be 
submitted to the IRB for review and approval.  Approval of both the protocol and the consent form must 
be obtained before any subject is enrolled.  Any amendment to the protocol will require review and 
approval by the IRB before the changes are implemented in the study.  
11.3    Informed Consent Process 
Informed consent is a process that is initiated prior to the individual agreeing to participate in the study 
and continues throughout study participation.  Extensive discussion of risks and possible benefits of 
study participation will be provided to subjects and their families, if applicable.  A consent form 
describing in detail the study procedures and risks will be given to the subject.  Consent forms will be 
IRB-approved, and the subject is required to read and review the document or have the document read 
to him or her.  The investigator or designee will explain the research study to the subject and answer 
any questions that may arise.  The subject will sign the informed consent document prior to any study-
related assessments or procedures.  Subjects will be given the opportunity to discuss the study with 
their surrogates or think about it prior to agreeing to participate.  They may withdraw consent at any 
time throughout the course of the study.  A copy of the signed informed consent document will be given 
to subjects for their records.  The rights and welfare of the subjects will be protected by emphasizing to

them that the quality of their clinical care will not be adversely affected if they decline to participate in 
this study. 
The consent process will be documented in the clinical or research record.   
11.4 Subject Confidentiality 
Subject confidentiality is strictly held in trust by the investigators, study staff, and the sponsor and their 
agents.  This confidentiality is extended to cover testing of biological samples and genetic tests in 
addition to any study information relating to subjects. 
The study protocol, documentation, data, and all other information generated will be held in strict 
confidence.  No information concerning the study or the data will be released to any unauthorized third 
party without prior written approval of the sponsor. 
The study monitor or other authorized representatives of the sponsor may inspect all study documents 
and records required to be maintained by the investigator, including but not limited to, medical records 
(office, clinic, or hospital) for the study subjects.  The clinical study site will permit access to such 
records.

DATA HANDLING AND RECORD KEEPING 
The investigator is responsible for ensuring the accuracy, completeness, legibility, and timeliness of the 
data reported.  All source documents should be completed in a neat, legible manner to ensure accurate 
interpretation of data.  The investigator will maintain adequate case histories of study subjects, 
including accurate case report forms (CRFs), and source documentation. 
12.1   Data Management Responsibilities 
Data collection and accurate documentation are the responsibility of the study staff under the 
supervision of the investigator.  All source documents and laboratory reports must be reviewed by the 
study team and data entry staff, who will ensure that they are accurate and complete.  Unanticipated 
problems and adverse events must be reviewed by the investigator or designee.   
12.2 Data Capture Methods 
Data will be collected on paper and entered electronically on a password protected network computer. 
Data quality checks will be performed internally on a routine basis.  
12.3   Types of Data 
Subject medical history, demographics, concomitant medications will be collected. The following 
outcome data will be collected: ankle and knee RPOM, MAS, TS, Gait Mat data on temporal spatial data 
including SSV and MV without and with shoes.
