In the last few years robotic exoskeletons has been developed to assist people with lower limb impairments. These devices are able to improve physical ability and allow people with disabilities reach their full potential. They are also used to aid paralysis patients recovering from stroke, spinal cord injury, and other neurological conditions. Exoskeletons are seen as a way of encouraging more exercise by a variety of organizations. Unfortunately, patients with limited funds may find it difficult to access the equipment because of the high price. These devices are being developed at a higher rate and many companies are now entering this market.
The first exoskeleton with force amplification was the MAN-Amplifier, developed by Cornell Aeronautical Labs. The MANAmplifier was a system that utilized a servomotor for driving a pneumatic drive. 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 is also designed to enable people to climb steep slopes.
Exoskeletons have been shown to improve gait function in patients suffering from acute injuries or chronic illnesses. There have been numerous studies. Exoskeleton use has also been studied in relation to cardiovascular health, body composition and gait parameters. These studies provided preliminary evidence of the ability to improve gait function for patients with SCI. These studies did not evaluate the effectiveness of exoskeletons on different applications or with different types of patients.
Robotic exoskeletons can help patients improve their mobility, ability to perform activities and social participation. They can be used to provide independence in rehabilitation and medical settings. However, patients must be properly trained in the use of exoskeletons. The trainer must also be able provide hands-on training for patients to use the exoskeleton.
The Honda Walking Assist is an exoskeleton with hip robotics that can help stroke victims. The exoskeleton is composed of two motors, which transmit torque to user's thigh via two strap frames. The sensors on the exoskeleton are able to measure the wearer’s speed and direction while walking. The sensors allow the exoskeleton to adjust its motors to provide assistance to the wearer. It can also provide power to the hips and knees.
Soft Exosuit - A flexible textile material exoskeleton which optimizes metabolic energy during walking. A Bowden line drives the Soft Exosuit. The depth camera is used to gather information about the environment. It also employs machine learning algorithms that recognize walking patterns. A four-point binding system provides stability while standing and is included in the exoskeleton.
Soft Exosuit, a lower extremity robotic exoskeleton, was also developed by Connor Walsh and his team at Harvard University. This exoskeleton is equipped with auxiliary torques that are applied to human joints to increase flexibility. Soft Exosuit optimizes walking and uses the auxiliary torques in order to reduce joint stress.
