Robotic exoskeletons were developed over the years to aid people with lower limb impairments. These devices improve human physical capabilities and can help disabled people reach their full potential. These devices can be used to help paralyzed patients recover from strokes, spinal cord injuries, and other neurological conditions. Exoskeletons have been supported by many organizations as a means to increase physical activity among people with SCIs. Unfortunately, patients with limited funds may find it difficult to access the equipment because of the high price. Diverse companies are now entering market after increasing their investments in the development of these devices.
Cornell Aeronautical Labs was the inventor of the MANAmplifier. It is the first exoskeleton equipped with force amplification. The MAN–Amplifier was a system which used a servo motor and a pneumatic drive to drive it. It was designed to help people with physical disabilities walk more smoothly. The exoskeleton, in addition to its motors, was also designed to increase strength. The exoskeleton was also designed to help people climb steep slopes.
Several studies have examined the effectiveness of exoskeletons in improving gait function in patients with acute injury or chronic illness. Researchers have also looked at the effects of exoskeletons upon cardiovascular health, body structure, and gait parameters. These studies provide preliminary evidence that exoskeletons may improve gait function in patients suffering from SCI. These studies did not evaluate the effectiveness of exoskeletons on different applications or with different types of patients.
Robotic exoskeletons could help patients to improve mobility and physical activity, as well as their social participation. They can also help patients feel more independent in rehabilitation or medical settings. However, patients must be properly trained in the use of exoskeletons. A certified trainer must also be able to provide patients with hands-on training to help them use the exoskeleton.
The Honda Walking Assist is an exoskeleton with hip robotics that can help stroke victims. The exoskeleton includes two motors which transmit torque from the user's hip through two strap frames. Sensors in the exoskeleton can also measure the speed and direction that the wearer is walking. The sensors enable the exoskeleton's motors to be adjusted to give the wearer the right assistance. They can also power the wearer’s hips or knees.
Soft Exosuit is a flexible textile fabric exoskeleton that maximizes metabolic energy usage during walking. A Bowden line drives the Soft Exosuit. The exoskeleton is equipped with a depth camera that is used to gather environmental information. It also uses a machine learning algorithm that recognizes walking patterns. The exoskeleton comes with a 4-point binding system to provide stability while standing.
Soft Exosuit, a robotic exoskeleton designed for lower extremities and developed by Connor Walsh’s Harvard University team. The Soft Exoskeleton comes with auxiliary torques which can be applied to human joint to increase flexibility. Soft Exosuit helps optimize walking mode and reduces joint stress by applying the auxiliary torques.
