“…Subsequently, 'hemiplegia' signifies overall sense and nerve function loss (paralysis) of one half of the human body, which including one arm and leg. Any sickness or injury in the physiological motor center of human can cause hemiplegia [2]. Half of the body influenced is not quite the same as the states of paraplegia and quadriplegia, which are regularly mistaken for Hemiplegia.…”

“…On the off chance that the individual encounters injury on the left half of the head, at that point the right side of the body will be influenced.Right hemiplegia will occur when the left portion of the brain is damaged..Left hemiplegia often presents when the right portion of human brain is altered or damaged. It usually presents with Loss of control over purposeful movements, unable to use objects correctly and unable to draw, comb hair or cook [2,7].…”

“…Electromyogram (EMG) is the graphical representation of the biological electrical activity of the human muscle, which can be recorded using electromyograph. Here, we acquire the EMG signal through surface electrodes [2,7]. It is recorded to know the recovery status of the muscle after the movements by exoskeleton.…”

“…The Indian Council of Medical Research assessed that, there were 9.3 lakh instances of stroke and 6.4 lakh expired because of stroke in India. The quantity of new cases every year remains at around 100,000; it costs the NHS £2.3 billion per year to treat and care for stroke casualties.Health care professionals such as physical therapists play a large role in assisting these patients in their recovery hence the training duration is usually limited by personnel shortage and/or exhaustion of therapist.Physiotherapy is a labor intensive, manual assisted training and therefore training duration is usually limited by personnel shortage and/or exhaustion of therapist [2][3]. Moreover in recent times, the problem has been increased with increase in number of people affected by hemiplegia.Existing systems like the Lokomat, the LOPES or the ALEX are stationary systems and used in hospitals or rehabilitation centers [4] to assist the rehabilitation training.…”

Paralysis is a condition in which the muscle function is lost in a part of the body. Paralysis is mainly caused as a result of severe stroke, where in the blood supply to a part of the brain is cut off. Hemiplegiais a type of paralysis which affects half of the body includes one arm and one leg on the same side of the body. The case of left Hemiplegia is taken into account, which is caused by the absence of blood supply to the righthemisphere of the brain. Stationary systems like Lokomat, used in the rehabilitation centres to assist training, provide highly repetitive action and just assistance to the patient’s capabilities while walking on a treadmill. However these systems are not portable and cannot be used for home or daily activities. To overcome this, this paper presents the rehabilitation system, which comprises of an exoskeleton that aids the movement of the left upper limb. The entire system is driven by a motor through a microcontroller system which assists patient’s flexion and extension movements. Meanwhile, EMG signal can be recorded by placing surface electrodes to know the recovery of physiological motor function.
