About this study
Official title: Hummingbird: Advancing Technology for Motor Recovery in Hand and Fingers for Stroke and Spinal Cord Injury
This study will use evaluate a hand therapy device training isolated finger control with engaging video gaming technology to facilitate hand and digit recovery in patients with acute stroke and cervical spinal cord injury. This study will randomize patients to either standard rehabilitation care with added study-related motor training or standard rehabilitation care alone.
Read the detailed description
The purpose of this project is to develop a usable bedside hand therapy device that that takes advantage of early neuroplasticity following stroke and cervical spinal cord injury (SCI), to retrain functionally relevant movement in individual fingers of the neurologically impaired hand. It is well established in neuroscience that neural recovery and neuroplasticity at the level of cortex in animals and humans is dependent on active motor practice. In this pilot project the investigators will determine and assure that this second-generation device, which has not yet been used in humans, is usable in the clinical setting and that patients with stroke and cervical SCI find it a meaningful tool for relearning hand movement. The investigators will also assess whether use of the device daily for 2 weeks results in improved functional hand use, improve finger strength and improved ability to control individual finger movements. Although these abilities are foundational to functional manipulation of objects with the hand, there is presently no specific therapeutic interventions, nor time available in conventional early (acute) rehabilitation to address these goals. Thus, early intensive hand recovery is an obvious but unmet need in neurorehabilitation. The goals for this one-year project are determine if the device:
- can facilitate improve hand function.
- can improve finger strength and individuation.
- is usable in a clinical setting and serves as a meaningful therapy tool to patients with stroke and cervical SCI.
If successful, this project will lead to a refined therapy protocol in preparation for a larger clinical trial to establish efficacy of this training approach for both stroke and cervical spinal cord injury. Both stroke and SCI populations were chosen as this tool could potentially have benefit for both groups. In addition, studying both patient populations provides generalizability to a wider group of individuals needing rehabilitation. If outcomes are suggestive of efficacy this device will evaluated in a large multi-center pivotal trial in preparation for transition to the clinical marketplace as new rehabilitation technology that has proven scientific evidence supporting its efficacy in early hand rehabilitation.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Hummingbird hand training device plus standard of care rehabilitationDevice
The Hummingbird is a comprehensive hardware and software platform that isolates the hand, wrist, and forearm in a neutral and comfortable position, allowing linear force and angular torque to be measured at the finger-tips between 0-10 Newtons at milli-newton resolution at 100 Hz per digit, in 5 degrees of freedom simultaneously, in real-time, for all 5 digits. The platform allows isolating and characterizing fine resolution forces with sufficient sensitivity and resolution to record data in severe paralysis. The platform also comprises therapeutic software to train exploratory, individuated, and inter-digit complex finger movements by coupling force and torque output to NeuroAnimation physics-based virtual interface in engaging therapeutic experiences.
Comparison (sham) interventionOther
During each hour of sham therapy the therapist will select cognitive tasks (e.g. puzzles and games) targeted to a level of difficulty based on the subjects ability. No grasping or object manipulation using the target upper limb will be included in this intervention. Rather, the participant will use either the unaffected limb (or non-targeted limb for SCI subjects) as needed for any particular puzzle or game.
| Study group | Role | What they receive |
|---|---|---|
| Hummingbird intervention group | Experimental | 10 one-hour sessions of focused hand training (affected or dominant hand) using the Hummingbird device in addition to standard of care inpatient rehabilitation Receives: Device: Hummingbird hand training device plus standard of care rehabilitation |
| Comparison (sham) group | Active comparator | 10 one-hour sessions of activity focused on playing games or puzzles gaged to the ability of the subject in addition to Standard of care inpatient rehabilitation Receives: Other: Comparison (sham) intervention |
What is being measured
The primary outcome is the main question the study is designed to answer.
Graded and Redefined Assessment of Strength, Sensibility, and Prehension (GRASSP) measure
Hand function test with 5 subtests including dorsal sensation (score 0-12), palmer sensation (score 0-12), strength (score 0-50), prehension ability (score 0-12) and prehension performance (score 0-30). Higher scores indicate better performance.
Measured: Baseline,72 hours Post-treatment, 2 weeks post treatment, and 3 months post treatment
Secondary outcomes (3)
Action research arm test (ARAT)
19-item measure divided into 4-subtests (grasp, grip, pinch, and gross arm movement). Scored 0-57 with higher score indicating better performance.
Measured: Baseline, 72 hours post-treatment, 2 weeks post treatment, and 3 months post treatment
Box and Block test
Number of 2.5 cm cubes transferred over a partition in 60 seconds
Measured: Baseline, 72 hours post-treatment, 2 weeks post treatment, and 3 months post treatment
Usability of the device (Intervention group only)
Finger strikes will be counted in each session. Usability will be defined by an increase of 50% or more of finger strikes per session over 10 treatment sessions
Measured: First day of treatment through 10th day of treatment (last treatment)
