Stroke Recovery Program
The Stanford Stroke Recovery Program is dedicated to improving the function and quality of life of stroke survivors. Based at Stanford University, the Program is uniquely positioned to bridge the barriers between neuroscience, engineering, and clinical research, to develop new therapies for stroke survivors. With grant funding from the Stanford Neurosciences Institute, the Program has brought together world-renowned scientists from a wide variety of disciplines, including stroke neurology, neurosurgery, neuroscience, mechanical, electrical, and bio-engineering, systems and molecular neuroscience, imaging/radiology, neuroimmunology, and genetics.
Our multi-disciplinary team of scientists is constantly innovating to develop new treatments that will improve gait, arm function and cognition after stroke. The medical innovations developed in our laboratories span a wide array, including immune-modulating therapies, stem-cell therapies, non-invasive brain stimulation (TMS), and medical devices developed by Stanford engineers. Being located in the center of Silicon Valley, the worlds most well-known hub for technological innovation, the Program has also established ties with multiple start-up companies that have developed innovative technologies to help patients recover from stroke. Our highly-experienced group of clinical scientists conducts trials to tests how effective these new treatments are at improving the symptoms of stroke survivors.
In addition to advancing research in the field of stroke recovery, we have a strong clinical neurologic rehabilitation program that serves stroke patients from the San Francisco Bay Area and beyond. A multi-disciplinary team of physiatrists, stroke neurologists, stroke nurses, physical therapists, occupational therapists, speech therapists, neuropsychologists, and social workers works together to provide the best care possible for our patients. The outpatient neurological rehabilitation program is based at Stanford Healthcare's state-of-the-art Neuroscience Health Center. The center, designed with the patient in mind, has an expansive gym with specialty equipment for patients with neurological impairments, spacious exam rooms, and convenient parking in the adjacent parking structure. The center is also home to the Neuroscience Supportive Care Program, which provides a variety of free support groups, classes, workshops, personal one-on-one consultations and services that are open to all patients and families in the community regardless of where they receive their stroke care.

Relatedly, are there specific subcircuits implicated in epilepsy that could be focally targeted for novel therapies.
Michelle L. James, PhD
Instructor, Radiology and Neurology & Neurological Sciences
My research is focused on developing and evaluating molecular imaging agents for visualizing neurological diseases in living subjects.
In particular, I am interested in imaging neuroinflammation, microglial activation, neurodegeneration, cognitive decline, and neurogenesis using positron emission tomography (PET). Non-invasive PET imaging of these biochemical processes in living, intact, subjects may lead to an enhanced understanding of a range of brain disorders (including Alzheimer’s disease, multiple sclerosis, and brain injury), ultimately generating effective diagnostic techniques and treatment strategies.
My Ph.D. was focused on the design and development of novel PET radioligands for imaging the translocator protein (18kDa) (TSPO). Since TSPO expression reflects microglial activation and neuroinflammation, radioligands for this protein may act as valuable tools for detecting regions of active brain disease before clinical signs manifest. These radioligands may also be used to track disease progression and monitor response to novel therapeutics.

The Stanford Stroke Center is recognized as a world leader in clinical stroke research. The physicians at the Stanford Stroke Center are always exploring new ways to diagnose and treat stroke. Our stroke recovery trials are designed to improve our understanding of how the brain recovers after stroke and to tests new treatments aimed at improving the lives of stroke survivors. Your participation in these trials will help us develop new rehabilitation therapies for future stroke victims. We are currently recruiting patients for the following trials:
Memory and other cognitive problems are common after stroke but the exact mechanisms of these problems is not well understood. In the StrokeCog study we follow stroke patients for several years during which we assess cognitive function every year. We also obtain a blood sample every year which we examine for the presence of markers of inflammation to determine if inflammation causes cognitive decline after stroke. Substudies are available for interested participants to look more deeply for neuroinflammation using cerebrospinal fluid and PET scans. StrokeCog is a study funded by the Stanford Neuroscience Institute.
The Neofect Smart Glove study tests the feasibility of the Neofect Smart Glove as an effective, home-based hand rehabilitation tool for recovering stroke victims. The Neofect Smart Glove system consists of the wearable Smart Glove with which participants use to interact with a tablet pre-loaded with games and activities. Using the system, participants will be asked to use the Smart Glove for an hour a day for five days a week over the course of 8 weeks. We will be evaluating participant's satisfaction of the system as a rehabilitation tool as well as monitoring progress to see if participants have improvement in their hand function.
StrokeCoach: A novel approach to home-based rehabilitation
StrokeCoach is an application for post-stroke rehabilitation geared to improve arm weakness. It uses the Apple Watch to provide patients with daily assessment of movements and progress of the weak arm to better follow their recovery. StrokeCoach also offers the patients with daily exercises created by our rehabilitation team. The exercies the degree of impairment of the patient using the application. With this study, we want to assess if StrokeCoach can be use to supplement therapy of stroke patients and see if it is a realiable way to assess recovery after stroke.
We will provide our participant with an AppleWatch and support during the duration of the study. We are looking for patients having suffered a stroke in the past and who currently have arm weakness.
StrokeCoach is an application that created by a Stanford multidisciplinary team of stroke and rehabilitation physician, occupational therapist engieneers, computer scientists and biology students.
Even after rehabilitation, many stroke survivors walk abnormally, with one leg taking a longer step than the other, resulting in a limp. This lack of symmetry in walking is correlated with decreased balance and slower walking speeds. We are investigating different learning techniques with motion capture that allows us to accurately track each step and give real-time feedback to promote walking more symmetrically.
Proprioception is a person's sense of their own body in space, without having to rely on vision. For example, proprioception is how we know whether our arm is raised or lowered without looking at it. In this study, we use a robotic support to assess arm proprioception. Stroke survivors will move and identify the location of their supported arm so that we can model the effects of proprioception on movement control. These models can be used in the future to influence the design of new rehabilitation technologies.
After a stroke, individuals frequently have difficulty lifting their arms due to muscle weakness, stiffness, or a loss of control of individual muscles. Several devices exist to help rehabilitate those experiencing these problems, but they are expensive, cumbersome, and complicated. We are developing inexpensive, unintrusive, and simple devices and testing their effectiveness for providing portable assistance for rehabilitation after stroke.
The ACTIsSIMA (“Allogeneic Cell Therapy for Ischemic Stroke to Improve Motor Abilities”) trial studies if an injection of stem-cells into the brain increases arm strength in patients with persistent arm weakness up to 5 years after their stroke. Patients who participate in the study are randomized to receive active treatment (an injection of stem-cells into the brain) or a sham surgery during which nothing is injected into the brain. Details of the study are at clinicaltrials.gov.
The Collins biomechatronics lab develops wearable robots and exoskeletons that improve mobility for individuals whose strength and coordination have been affected by stroke, amputation, or aging. Using these devices it may be possible to restore function or even enhance performance beyond typical human limits.
The Shamloo lab studies normal and pathological brain function with the long-term goal to discover novel therapeutic approaches for neurologic disorders such as stroke, Alzheimer’s disease (AD), and autism. The lab has focused its efforts on characterizing genes and proteins that are involved in neuroprotective or neurodegenerative pathways.
The Brain Interfacing Laboratory is interested in the applicability of brain-machine interfaces as a platform technology for a variety of brain-related medical conditions, particularly stroke and epilepsy. This research spans both preclinical models and human clinical studies.
With respect to stroke, we are exploring how the brain recovers from injury in translational preclinical models. This investigation leverages multichannel electrode arrays to gather a neural population estimate of the state of the brain. The goal here is to develop and then leverage a neural biomarker to guide stroke rehabilitation, with the aim of improving both the rate and total recovery from stroke.
