Clinical Trial Summary

This pilot study will examine a combination therapy for adults with chronic, severe motor impairment of an arm after stroke. The intervention will combine brain stimulation with physical rehabilitation of the arm on the side of the body more-affected by stroke.

Description:

The overarching goal of this program of research is to develop a therapy that produces meaningful and persistent improvements in function of the more-affected arm in stroke survivors with severe, chronic hemiparesis. No treatment with an established evidence base is available now for this large group, who have barely perceptible voluntary movement of the more-affected fingers and wrist. The lab of E. Taub and G. Uswatte has developed an expanded version of Constraint-Induced Movement therapy (CIMT) for this population that has evidence of efficacy for improving use in daily life of the more-affected arm from a case series and small randomized controlled trial (RCT). The original version of CIMT is a form of physical rehabilitation that has evidence of efficacy from multiple RCTs for improving use in daily life of the more-affected arm in adults with mild to moderate hemiparesis after stroke. CIMT has also been shown to produce neuroplastic changes in both grey and white matter structures. Expanded CIMT (eCIMT) combines CIMT with neurodevelopmental techniques (NDT) for managing tone. Studies from by J. Szaflarski and by others suggest that priming CNS tissue for training by electrically stimulating the brain regions that control the target function with excitatory intermittent theta burst stimulation (iTBS) augments the benefits of neurorehabilitation. This pilot study will evaluate the feasibility of combining eCIMT with brain stimulation by iTBS and, on a preliminary basis, will evaluate whether this combination therapy boosts treatment outcomes relative to eCIMT alone.

Intervention

Combination Product:
• iTBS&eCIMT
All will receive eCIMT+iTBS on an outpatient basis for 4 hours/day for 15 consecutive weekdays. eCIMT will include training of the more-affected arm following shaping principles, restraint of the less-affected arm, and the Transfer Package in combination with NDT techniques to reduce tone so that shaping of movement can be carried out. The Transfer Package is a set of behavioral techniques designed to transfer therapeutic gains from the treatment setting to everyday life. iTBS will be added to prime the areas of the brain that control movement of the more-affected arm so that the responsiveness of that tissue to motor training is enhanced. Treatment sessions will alternate between 10 minute periods of iTBS (which include time for set-up and transition) and 1-hour periods of eCIMT.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Motor Activity Log (MAL)	Structured interview that assesses use of the more-affected arm in daily life. Scale range is 0 (no use of the more-affected arm) to 5 (use that is as good before stroke). Higher scores are better. Score reported is change from Day 0 to Day 42.	Change from Day 0 to Day 42
Secondary	Wolf Motor Function Test (WMFT)	Laboratory motor performance test that assesses motor capacity of the more-affected arm. Scale range is 0 to infinite. Higher scores are better.	Change from Day 0 to Day 42
Secondary	Canadian Occupational Performance Measure (COPM)	Structured interview that assesses use of the arms in daily life	Change from Day 0 to Day 42
