Weight Training and Exercises for Stroke Patients

Chris Kaiser, Cardiology Editor of ”MedPage Today” reports on ”Working with Weights” for stroke rehab patients. The article is reviewed by Zalman S. Agus, MD; Professor Emeritus , Perelman School of Medicine at the University of Pennsylvania etal. This is a preliminary study of a 6 month study program for combined aerobic and resistance training which resulted in improvements in cognitive function for post stroke patients. The idea was to incorporate resistance training — often overlooked in stroke rehab — that may help improve cognitive skills in stroke survivors. In addition to that aerobic exercise also contributed to improvements in cognition at 6 months, according to Susan Marzolini, BPHE, MSc, of the Toronto Rehabilitation Institute, and her colleagues. Resistance training is not usually a standard component of stroke rehab, according to Marzolini. She stated that “To measure the muscle mass, we used dual-energy x-ray absorptiometry, which is a very precise method. We found that the greater the improvement in muscle mass, the greater the improvement in cognition.” The muscles that were affected most by stroke in this study were those for walking — especially, the hip flexors, which raise the knees up, and the pretibial muscles, which lift the toes up. Many rehab centers have stroke patients only moving their legs, but under the revised program weights are added. The intensity of the amount of weight is the key to their improvement,” according to Marzolini. Marzolini determines the heaviest weight a patient can lift, divides that by half, and then proceeds with 10 repetitions. The reps are then increased gradually. When the patient shows he is ready for more weight, he drops back down to 10 reps. In addition patients also use resistance bands in order to strengthen weak muscles. Resistance training has also added an overall 30% improvement in bilateral strength. Marzolini and her colleagues found an association between positive changes in concentration and attention and aerobic exercise, as it was measured by maximal oxygen consumption. This was independent of time from stroke, sex and change in fat mass and depression score . Forty one patients were studied who suffered a mild or moderate stroke. The mean age was 63, and 70% of the patients used some type of walking assistance. The time from stroke to the start of rehabilitation varied from several months to 5 years. By using the Montreal Cognitive Assessment test, the researchers found that this training program resulted in a significant overall improvement in cognition and specifically in attention and concentration at 6 months following rehabilitation. Marzolini and her team is preparing for stage two of this research, which is a study that randomizes stroke patients to aerobic and resistance training or exclusively resistance training. “I suspect aerobic and resistance training are working synergistically,” Marzolini said. Marzolini feels that exercise is very important for everyone, and especially for stroke patients. Rehab programs should include both strength and aerobic training. In line with the thinking of Marzolini when it comes to exercising limbs that have been affected by strokes the most effective physical therapy products should be used. One of the most efficient such devices currently in use in leading rehabilitation centers worldwide is the TUTOR system. The HANDTUTOR and its sister devices (ARMTUTOR, LEGTUTOR and 3DTUTOR) has become a key system in neuromuscular rehabilitation for stroke victims as well as for those recovering from brain and spinal injuries, Parkinson’s, MS, CP and other limb movement limitations. These innovative devices implement an impairment based program with augmented motion feedback that encourages motor learning through intensive active exercises and movement practice. The TUTOR products consist of a wearable glove or braces that detect limb movement showing the patient how much active or assisted active movement they are actually doing. The rehabilitation software uses special rehabilitation games to set a new target for this movement in terms of the patient’s ability to move their limb. The devices then measure the limb movement and give feedback to the patient. In this way the TUTOR system provides exercises that are challenging and motivating and allow for repetitive and intensive exercise practice. The TUTORs are fully certified by the FDA and CE and can be used in the patient’s home through the use of telerehabilitation. See WWW.MEDITOUCH.CO.IL for more information.

Should a Patient Undergo Rehabilitation After Stroke?

Henrik S. Jørgensen, MD etal of the Department of Radiology, Bispebjerg Hospital, Copenhagen, Denmark cocnducted a study to determine the value of post stroke rehabilitation. The objective of the study was to evaluate the outcome of stroke divided according to both the severity of the initial stroke and the initial level of disability. The study took place in a stroke unit of a hospital in Denmark that receives all acute stroke patients admitted from a large catchment area of approximately 240,000 inhabitants within the City of Copenhagen. Under normal circumstances acute treatment as well as rehabilitation is cared for within the stroke unit regardless of age, severity of the stroke and premorbid condition. In this study 1197 patients with acute stroke were used. The Main Outcome Measures were: Primary outcome was measured as death, discharge to a nursing home, or to the patient’s own home. Secondary outcome was measured as the patient having neurological deficits and/or functional disabilities after rehabilitation was completed and then again 6 months after the stroke occurred. The indices used were the Scandinavian Neurological Stroke Scale and Barthel . The results were as follows: Stroke was initially very severe in 19% of the patients, severe in 14%, moderate in 26%, and mild in 41% of the patients. Two hundred and fifty or 21% of the patients died during their hospital stay, 177 or 15% were discharged to a nursing home, and 770 or 64% of the patients were discharged to their home. After rehabilitation was completed 11% of the survivors still had severe or very severe neurological deficits, 11% had moderate deficits, and 78% had no or only mild deficits; 20% were severely or very severely disabled, 8% were moderately disabled, 26% were mildly disabled, and 46% had no disability in normal daily activities. The conclusions reached were that there is a great need for stroke rehabilitation in the community and the amount of postrehabilitation disability in stroke survivors cannot be exaggerated. Results, though, should not be used as a guideline for selecting patients for rehabilitation in the acute phase as even the most severe cases experience meaningful improvement during rehabilitation. The question then becomes what is the most effective physical therapy solution that can speed recovery of the affected stroke victim’s limbs. Other than robotic machines which are large and therefore usable only in rehabilitation facilities and hospitals or are cost prohibitive the physical therapy profession has come to know of the effectiveness of the TUTOR system. Consisting of the HANDTUTOR, ARMTUTOR, LEGTUTOR and 3DTUTOR these recently created products are in the forefront of stroke rehabilitation. These innovative devices implement an impairment based program with augmented motion feedback that encourages motor learning through intensive active exercises and movement practice. The HANDTUTOR, ARMTUTOR, LEGTUTOR and 3DTUTOR consist of wearable glove and braces that detect limb movement showing the patient how much active or assisted active movement they are actually doing. The rehabilitation software uses special rehabilitation games to set a new target for this movement in terms of the patient’s ability to move his limb. The devices then measure the limb movement and give him feedback on his success. In this way the Tutor system provides exercises that are challenging and motivating and allow for repetitive and intensive exercise practice. The TUTOR system is now part of the rehabilitation program of leading U.S. German, Italian, French, UK and other foreign hospitals and can be used at home through telerehabilitation. The TUTORs are fully certified by the FDA and CE. See WWW.MEDITOUCH.CO.IL for more information.
