Aerobic exercise significantly improves endurance and walking ability in stroke patients, finds study

Aerobic exercise significantly improves aerobic endurance and walking ability in stroke patients, finds new study.

The new research has found that stroke survivors who completed group-based aerobic exercise programs similar in design and duration to cardiac rehabilitation programs significantly improved their aerobic endurance and walking ability.


Although stroke remains the leading cause of disability current rehabilitation care following stroke has little to no focus on aerobic fitness and when continued rehabilitation activity is suggested patients often fail to keep active without any support or guidance, according to a study to assess the impact of aerobic exercise programs on endurance and walking ability after stroke.


The physical therapy we currently provide to patients after a stroke focuses more in improving the ability to move and move well rather than on increasing how far and long you can move, said the lead author of the study.  It doesn't matter how well you can walk, if your endurance level keeps you at home.


Nearly 500 adults average ages between 54-71 completed aerobic exercise programs similar in structure to cardiac rehabilitation.  Participants attended 2-3 sessions per week for about 3 months. Of nearly 2 dozen different exercise groups, walking was the most common type of activity, followed by stationary cycling as mixed mode aerobic exercise. Physical abilities were tested before and after the intervention.


Looking at results by activity type, researchers found-
*mixed aerobic activity provides the best result ( 4 treatment groups) followed by walking ( 12 treatment groups)
*cycling or recumbent stepping ( machine that allows stepping while in seated position) while still significant was the least effective ( 7 treatment groups)

*overall, participants significantly improved their endurance level and walking speed.
*On average, participants walked almost half the size of a football field during a 6 minute walking test. Participants with mild movement impairments benefited the most.

These benefits were realised regardless of how long it had been since their stroke, the Dr. said. Our analysis included stroke survivors across a wide range, from less than 6 months to greater than a year since their stroke, and the benefits were seen whether they started an aerobic exercise program one month or one year after having a stroke.


Cardiac rehab programs may be a viable option for patients after a stroke who have health risks and endurance losses similar to traditional cardiac rehab participants, said the study's co-author. Almost every hospital has a cardiac rehab program, so it's an existing platform that could be used for stroke survivors, Funneling patients with stroke into these existing programs may be an easy, cost-effective solution with long-term benefits.


While this study suggests group-based aerobic exercise programs improve health and endurance in stroke survivors, no control group analysis was performed for results comparison. Limited hollow-up data were available to determine whether the health benefits persisted.

Indian scientists develop world’s 1st robotic hand for paralytics

Scientists at the IIT-Kanpur have ventured into the world’s first robotic hand for the rehabilitation of stroke patients and have finished their tests on it.

The device is a two-finger robotic hand (exoskeleton) that uses a four-bar mechanism and has four degrees of freedom (DOF).

Professors who have achieved this feat, explain that “The exoskeleton can be used by a patient on the hand. It uses brain signals, with the help of the brain computer interface (BCI) that is worn on the head, and helps paralysed patients to open and close the movement of their thumb, forefinger and middle fingers for physical practice.”

The exoskeleton is operated by an MEGA microcontroller of 300 Mhz and powered by a battery. The teachers say that the device will cost around Rs 15,000.

For the exoskeleton, the duo has partnered with the University of Ulster, based in the United Kingdom, and their teacher who belongs to Gorakhpur.

The device has sensors that control the pressure of the fingertip applied by the patient. If the patient can close or move the finger, the device follows the movement passively. If it does not, then the device actively forces the finger to close, while taking BCI instructions using signals.

Regarding the design of the device, the movement of degrees of freedom of the exoskeleton is based on the movement of the human finger while manipulating a coin in the hands. The joints in the device consist of four bars to give a human movement.

The design and development of an exoskeleton robot for the support and rehabilitation of human hands is a Rs 55 lakh MHRD (Ministry of Human Resource Department) and the British Council (the UK) project which was approved in 2018.
