Richards, OTR/L, PhD Research Scientist BRRC University of Florida Occupational Therapy lrichard@phhp.ufl.edu 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 • Measure your Outcomes!

(Hamzei, et al., 2006) Participants with intact M1 and MEPs at baseline Participants with lesioned M1 and disturbed MEPs at baseline 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 Thank you!
