Brief Summary

Stimulation of the spinal cord and brain represents a new experimental therapy that may have potential to restore movement after spinal cord injury. While some scientists have begun to study the effect of electrical stimulation on patient's ability to walk and move their legs after lower spinal cord injury, the use of stimulation of the upper (cervical) spine to restore arm and hand function after cervical spinal cord injury remains less well explored. The investigators are doing this research study to improve understanding of whether cervical spinal cord stimulation and brain stimulation can be used to improve arm and hand function. To do this, the investigators will combine spine stimulation (in the form of electrical stimulation from electrical stimulation wires temporarily implanted next to the cervical spinal cord) and brain stimulation (in the form of transcranial magnetic stimulation). The investigators will perform a series of experiments over 29 days to study whether these forms of stimulation can be applied and combined to provide improvement in arm and hand function.

Outcome Measures

Primary Outcomes (2)

  • Serious adverse events related to the study device

    To assess safety of spinal cord stimulation and paired spine and brain stimulation for movement recovery after spinal cord injury, the investigators will record the number of serious adverse events related to the study device.

    From enrollment to the end of follow up at 30 weeks

  • Cessation of spinal cord stimulation or brain stimulation due to participant request

    To assess tolerability of spinal cord and brain stimulation for movement recovery after spinal cord injury, the investigators will record the number of instances a participant requests permanent cessation of stimulation.

    From enrollment to the end of follow up at 30 weeks

Secondary Outcomes (28)

  • Efficacy derived from spine-only and brain-only recruitment curves

    Compared at visit 7/8 to visit 24/25 (~end of week 2 and end of week 5)

  • Selectivity derived from spine-only and brain-only recruitment curves

    Compared at visit 7/8 to visit 24/25 (~end of week 2 and end of week 5)

  • Immediate effect of volitional motor activation combined with spinal stimulation

    Compared at visit 7/8 to visit 24/25 (~end of week 2 and end of week 5)

  • Immediate pairing effect of spine and brain stimulation

    Compared at visit 7/8 to visit 24/25 (~end of week 2 and end of week 5)

  • Lasting effects of sustained spine and brain pairing

    Compared at visit 7/8 to visit 24/25 (~end of week 2 and end of week 5)

  • +23 more secondary outcomes

Study Arms (1)

Epidural Spinal Cord Stimulation

EXPERIMENTAL

Participants will undergo temporary placement of cervical epidural spinal cord stimulation (SCS) electrodes. They will undergo 2 visits of stimulation optimization based on mapping of motor responses to SCS and clinical assessments at a range of SCS parameters. Once a stimulation plan has been established, subjects will undergo baseline assessments with and without SCS over 2 visits. Subjects will then undergo 15 days of continuous SCS in conjunction with structured rehabilitation with occupational therapy. On each day of therapeutic stimulation, subjects will receive two sessions of SCS plus structured rehabilitation (for up to 1.5 hours per session). Subjects will undergo a clinical assessment with and without stimulation at the midpoint of the therapeutic stimulation period. After this therapeutic stimulation period, subjects will undergo 2 days of repeat assessments.

Device: Epidural spinal cord stimulation and paired spine and brain stimulation

Interventions

The spinal cord and brain stimulator allows for stimulation of the spinal cord and brain. Spinal cord stimulation (SCS) is provided by temporarily implanted SCS catheter electrode leads (Medtronic) that are connected to an external stimulator (Digitimer); brain stimulation is provided by transcranial magnetic stimulation (TMS).

Masking Details
Given that this is a single-arm, open label study, complete masking is not possible. However, to the greatest extent possible, subjects will be blinded to the stimulation-on versus stimulation-off conditions during assessments. In support of the blind, the stimulation condition will be determined by randomization, and both the subjects and the assessors will be blinded to the assignment of the stimulation condition. The stimulation-on condition will begin with a gradual ramp up of stimulation over the course of a minute as subjects are known to acclimate to the presence of stimulation relatively quickly; likewise, the stimulation-off condition will begin with the same one-minute ramp up of stimulation followed by a ramp down of stimulation to off over one minute.
