Objectives
• As a Participant you will be able to:
* describe EBM in stroke rehabilitation
* identify individuals for constraint induced
movement therapy (CIMT)
* list key components of CIMT
* implement a CIMT session
* explain the scientific basis for CIMT
* identify limitations in evidence for CIMT
Introduction to Constraint
Induced Movement Therapy
CIMT
EXCITE TRIAL
Wolf SL et al. Effect of constraint-induced movement therapy on upper
extremity function 3 to 9 months after stroke. JAMA 2006;296:2095-2104
• Prospective, randomized, parallel group, multicenter,
phase III, single blind trial of 2 weeks of CIMT,
3 & 9 months after acute stroke
• Subjects:
– CIMT: N = 106
– Usual and customary care : N = 116
• Inclusion criteria:
– High functioning: 20˚ wrist ext, 10˚ finger ext.
– Low functioning: 10˚ wrist ext, 10˚ ext. thumb & ≥ 2 other fingers.
– Motor Activity Log (MAL) < 2.5
• CIMT: up to 6 hrs/day + mitt worn 90% of waking hrs.
• Outcome measures: Wolf Motor Function Test
MAL- Quality of motion at 1-year.
EXCITE Trial
First: Identify Individuals for
CIMT
• CIMT is a beneficial treatment for patients post stroke
exhibiting some active wrist and hand movement.
Wolf et al 2006,Dromerick et al 2000, Van der Lee et al1999
Minimum Motor Criteria:
Active extension must be repeated 3x in one minute:
From a relaxed resting position,
Not from a neutral wrist position.
At least 10 degrees: wrist, thumb and 2 digits
Include Key Components of
CIMT
• Add these elements to each session:
* Massed Repetition
* Graded/progressed activities
* Objective Feedback
* Restraint of the less involved UE
* Intensive Practice:
Original CIMT included 6 hours/day for 5 days a week for 2 weeks
What does a CIMT Session
Look Like?
• Choose Shaping (lower functioning) or
Task Practice (higher functioning)
Shaping: Components of the task are made more difficult
in a more structured way to attain the task.
Detailed feedback & progress only when attain set goal
Example: reach - to grasp - to lift a glass – to drink
Task Practice: Functionally based activities performed
continuously 15-20 minutes or until the task is attained.
Example: fix a sandwich & eat lunch
More general feedback & graded progression
To Progress:
Add specific challenges i.e.
speed, height, distance, weight, #’s, dual task, quality of movement
Choose CIMT tasks to match the
Individual
Design CIMT Menu of
Unique Tasks
• To meet the unique individual’s needs:
* impairment level
* interests
* roles inventory
* meaningful activities
* functional needs
* strength
* coordination
* range of motion
* sensation
* personal goals
* endurance
* sense of humor
Creative Considerations for
CIMT and modified mCIMT
*Setting
*Acuity
*Length of Stay
*Staffing
*Support
*Modifications
*Home Program
*Charge and Reimbursement
*Legal and Ethical considerations
Standardized tests to take to clinic

• Translational Package
Morris,Taub,Mark,2006
* Contract 90% mitt wearing
* Diary
* Coach agreement
* Daily cues: Motor Activity Log
* Home Practice
* Weekend Practice
* Daily Schedule
* Agreed upon appointments
* Agreed upon time to remove mitt
Constraint Induced Movement
Therapy
• A family of therapies
• Developed from deafferented monkey studies
(Knapp, Taub, et al., 1958; Taub, 1976, 1977)
– Without sensation, monkey did not use the limb
– Would use the arm if the other arm were restrained
– Restraint of 1-2 days = revert after restraint removal,
but not after 1-2 weeks
– Shaping also increased ability and use of limb
Constraint Induced Movement
Therapy
• Developed to improve motor skill and to
decrease learned non-use

shaping, 5 hr/d mitt

Is there evidence that CIMT
changes the brain?
• 2 most common methods:
– Transcranial Magnetic Stimulation
(TMS)
– Functional Magnetic Resonance Imaging
(fMRI)
Is there evidence that CIMT
changes the brain?
(Hamzei, et al., 2006)
Participants with
intact M1 and MEPs
at baseline
Participants
with lesioned
M1 and
disturbed MEPs

CIMT now Paired
• With other Therapies:
* Drugs
* Strengthening
* Rhythm Cues
Remaining Questions
• Future Research Needs to Demonstrate
* What is the Best CIMT Schedule:
- Distributed versus Massed
- # of Hours
- Maintenance of the gains
Summary
• Evidence shows:
- CIMT is efficacious
- Variations of the original protocol are
efficacious and can translate to clinic
- More therapy is generally better
- CIMT is reimbursable
