Researchers from the University of Cincinnati Academic Medical Center evaluated and compared the efficacy of 20-, 40-, and 60-minute mental practice (guided imagery) sessions on affected upper extremity impairment and functional limitation, using a randomized, controlled study with a multiple baseline design.
Twenty-nine subjects with chronic stroke, exhibiting stable, mild hemiparesis (weakness on one side), were given 30-minute rehabilitative sessions, 3 days/week for 10 weeks, emphasizing affected upper extremity use during valued activities.
Researchers from Northumbria University in Newcastle upon Tyne, UK, conducted a randomized, controlled trial to evaluate the therapeutic benefit of mental practice with motor imagery in stroke patients with persistent upper limb motor weakness.
Recent studies have suggested that mental rehearsal of movement can produce effects normally attributed to practicing the actual movements. Imagining hand movements could stimulate restitution and redistribution of brain activity, which accompanies recovery of hand function, thus resulting in a reduced motor deficit. Current efficacy evidence for mental practice with motor imagery in stroke is insufficient due to methodological limitations.
I am an occupational therapist working with elders who have suffered a stroke. I am interested in incorporating your stroke CD in my treatment. While I have used your guided imagery CDs myself and found them very helpful, I'm wondering whether there are any precautions I should be aware of prior to using them with my patients.
Thanks for your response, and for your important work!
Warmly,

Dear Daria,
There are no special counter-indications for stroke patients that I’m aware of or that have ever been reported to me. One consideration, however, is that some of your elderly patients may suffer from hearing loss - especially in the lower registers – and this could mean they have trouble hearing my voice over the music. It’s something to be alert for.
The usual orientation should be fine: reminding people to sit comfortably, relax to it, to not try too hard or think too hard about it, but rather just let the images soak in, in an easy, open, receptive way. Over time, they will take hold below the thinking brain, deep in the body.

Researchers from McGill University in Montreal analyzed research data on the effectiveness of Virtual Reality for retraining motor function of the upper limbs in stroke patients. They posed two questions to examine: (1) Is the use of immersive VR more effective than conventional therapy or no therapy in the rehabilitation of the UL in patients with hemiplegia? and (2) Is the use of nonimmersive VR more effective than conventional therapy or no therapy in the rehabilitation of the UL in patients with hemiplegia?
Researchers from the Department of Physical Medicine & Rehabilitation at the University of Cincinnati’s Academic Medical Center looked at the impact of “mental practice” (the imaginal rehearsal of physical movements) on affected arm movements in stroke patients, as well as changes in cortical mapping in the brain.
Mental practice (MP) is a noninvasive, inexpensive method of enabling repetitive, task-specific practice (RTP) which has been shown in past studies to increase affected arm use and function significantly more than just RTP alone.
As a next step, this 10-subject case series examined the possibility
that cortical plasticity is a mechanism underlying the positive
treatment effect from mental practice (MP) when combined with RTP
(repetitive task-specific practice). Ten chronic stroke patients (mean
= 36.7 months) exhibiting stable, moderate motor deficits, received
30-minute therapy sessions for their affected arms 3 days/week for 10
weeks, emphasizing valued activities of daily living (ADLs).
Interested in building upon recent studies showing that imagery helps post-stroke patients relearn daily tasks, researchers from the Hong Kong Polytechnic University in Kowloon, Hong Kong, China investigated whether imagery could also help with generalizing skills on trained and untrained tasks in new environments in a small, randomized, controlled clinical trial.
Thirty-five acute post-stroke patients were randomly assigned to an
imagery training group (n=18) or conventional functional rehabilitation
(n=17) group. The imagery intervention was 3-weeks of standardized
practices and daily tasks using chunking-regulation-rehearsal
strategies.
Outcome measurements were the performances on trained and untrained tasks in the training and novel environments.
Researchers from the All India Institute of Medical Sciences in New Delhi examined the short-term impact of a brief yoga intervention on some of the biochemical risk indicators for cardiovascular disease and diabetes mellitus.
Ninety-eight subjects (67 male, 31 female), ages 20-74, with hypertension, coronary artery disease, diabetes mellitus, and a variety of other illnesses, participated in a lifestyle training program that consisted of yoga asanas (postures), pranayama (breathing exercises), relaxation techniques, group support, individualized advice, lectures and films on the philosophy of yoga and the place of yoga in daily life, meditation, stress management, nutrition, and knowledge about their disease.

IMAGERY SHOWS BIG GAINS FOR POST-STROKE HEMIPARESIS
Researchers from the Wingate Institute in Netanya, Israel, tested the feasibility of using a home-based motor imagery gait training program to improve walking performance of people suffering from chronic poststroke hemiparesis.
Seventeen community-dwelling volunteers with hemiparesis caused by a unilateral stroke that occurred at least 3 months before the study were recruited. They received 15 minutes of supervised imagery gait training in their homes 3 days a week for 6 weeks. The intervention addressed gait impairments of the affected lower limb and task-specific gait training.
Walking ability was evaluated by kinematics and functional scales twice before the intervention, 3 and 6 weeks after the intervention began, and at the 3-week follow-up.
Imagery Rehearsal Found Critical in Motor Rehab for Stroke, Better than Physical Practice Alone
Researchers from the University of Lyon in Bron Cedex, France
tested whether "mental rehearsal" (motor imagery) is equivalent to
physical learning in restoring motor function in hemiplegic patients
(paralyzed on one side), and examined what would be optimal proportions
of real execution vs. rehearsal.
Subjects were asked to grasp an object and insert it into an adapted
slot. One group (G0) practiced the task only by physical execution (240
trials); three groups imagined performing the task in different rates
of trials (25%, G25; 50%, G50; 75%, G75), and physically executed
movements for the remaining trials; a fourth, control group imagined a
visual rotation task in 75% of the trials and then performed the same
motor task as the other groups.
