An Artificial Interface Between Brain and Hand Muscles Bypasses Damaged Nerves

Researchers here report on the use of a combination of a brain-computer interface and functional electrical stimulation of muscles to bypass damage leading to paralysis of the hand, allowing some degree of restored function. The approach was demonstrated in non-human primates in which nerves connecting the hand to the brain were damaged via surgery. Competition in approaches to the problem of nervous system damage is a good thing, but one would hope that this class of application of brain-computer interface is largely made irrelevant by future advances in regenerative medicine. Paralysis following stroke is a leading cause of long-term motor disability. Brain machine interfaces (BMIs) can transform cortical activity into control signals for an external device, such as a robotic arm or computer cursor, and may provide a solution for restoring lost function. Bypassing the damaged pathway using brain-controlled functional electrical stimulation (FES) to regain volitional control of the paralysed limb is promising for restoring lost motor function. Brain-controlled FES works as an "artificial" neural pathway by creating a causal relationship between brain activity and an evoked limb movement. However, subjects may be required to learn a novel causal input-output relationship to control the paralysed limb. Disruption of descending pathways, as can result from stroke, results in a lost connection between the brain and target muscles. Functional recovery in...

Are healthy habits worth cultivating? A recent study suggests healthy habits may help people tack on years of life and sidestep serious illnesses, such as diabetes and cancer. After all, if you’re going to gain an extra decade of life on this earth, you want to enjoy it! What did this research focus on? Researchers from the Harvard T.H. Chan School of Public Health looked at data from more than 73,000 women enrolled in the Nurses’ Health Study (NHS) who were followed for 34 years, and more than 38,000 men enrolled in the Health Professionals Follow-up Study (HPFS) who were followed for 28 years. In a previous s...

Stroke is a major cause of death and disability across the world, with many reviews from the Cochrane Stroke Group providing evidence on the effects of treatments and rehabilitation interventions. In November 2019, the Group published their update of their review of selective serotonin reuptake inhibitors and we asked lead author, Gillian Mead from the University of Edinburgh in Scotland, to tell us more.

Conclusions: Programs offering a variety of adaptive paddle boarding and kayaking configurations enable paddlers to make valued choices about their participation. In addition to providing equipment and support to meet paddlers' functional abilities, program developers and clinicians should also consider individual preferences for exercise, socialization, risk taking, self-presentation of disability, and independence.IMPLICATIONS FOR REHABILITATIONPeople living with physical, cognitive, and/or psychosocial impairments perceive kayaking and paddle boarding as meaningful activities offering opportunities to exercise, have fun...
