Send your doctor after the EXACT stroke protocols needed for this. They didn't seem to answer any questions about how much neurogenesis and angiogenesis is created from this. A failure of this research.

High-intensity interval training is a promising rehabilitation
strategy for chronic stroke patients and may be superior to the current
guidelines of moderate-intensity continuous exercise, new research from
the University of Cincinnati (UC) shows.
The research was presented Wednesday, Feb. 11, at
the American Heart Association/American Stroke Association (AHA/ASA)
International Stroke Conference 2015 in Nashville, Tennessee. Pierce
Boyne, PT, DPT, NCS, a doctoral student and research assistant professor
in the UC College of Allied Health Sciences' Department of
Rehabilitation Sciences, is the study's lead author and project
director.
Co-authors included Kari Dunning, PT, PhD, an associate professor in
the Department of Rehabilitation Sciences, and Brett Kissela, MD, MS,
Albert Barnes Voorheis Chair of Neurology and Rehabilitation Medicine in
the UC College of Medicine and a member of the UC Neuroscience
Institute. They are Boyne's mentors and were the principal investigators
on two pilot grants that funded the project, which also included
collaborators from Cincinnati Children's Hospital Medical Center and the
College of Medicine's Department of Internal Medicine.
Current AHA/ASA post-stroke guidelines recommend moderate-intensity
continuous exercise to improve aerobic fitness, mobility and
cardiovascular health. High-intensity interval training differs from
moderate-intensity continuous exercise by augmenting exercise intensity with bursts of concentrated effort alternated with recovery periods.
"In patients in the chronic stage of stroke recovery (six months or
longer post-stroke), aerobic deconditioning is a major barrier to
recovery," Boyne says. "We wanted to make a preliminary assessment of
the comparative efficacy of high-intensity and moderate-intensity
continuous exercise for improving aerobic capacity and walking function
in chronic stroke."
Previous research has shown that high-intensity interval exercise is
more effective than moderate-intensity continuous exercise for improving
aerobic capacity among healthy adults and persons with heart disease.
However, he says, no previous study has compared the two among persons
with stroke.
Boyne and colleagues from the College of Allied Health Sciences
Department of Rehabilitation Sciences, the UC College of Medicine's
Departments of Internal Medicine and Neurology and Rehabilitation
Medicine and Cincinnati Children's Hospital Medical Center recruited 16
subjects with residual gait impairment from stroke, all of whom passed a
treadmill stress test prior to enrollment in the study. They were
randomized to high-intensity interval training or moderate continuous exercise for 25 minutes, three times a week, for four weeks.
The high-intensity interval group alternated 30 seconds of maximum
tolerated treadmill speed with 30- to 60-second rest periods. The
moderate continuous exercise group did continuous treadmill walking at
40 to 50 percent heart rate reserve. Outcomes were measured pre- and
post-training by a blinded rater who assessed peak oxygen uptake,
aerobic capacity, energy cost of walking, floor walking speed and
treadmill walking speed.
Subjects in the high-intensity interval group showed significantly
greater improvement in aerobic capacity and treadmill speed, Boyne says,
with at least moderate improvement in the other categories. The
moderate-intensity group showed essentially no change in the same time
period, indicating that exercise intensity may be a key factor.
"These results show that high-intensity interval exercise is a potent intervention for improving aerobic capacity
and walking function in chronic stroke," Boyne says. "This is extremely
promising because these changes occurred in just four weeks of
training. However, further study with a larger sample is needed."
