Tech Talk: A bionic leg made for walking
A neuroprosthetic interface allows a bionic leg to be fully responsive to the human nervous system, a new report suggests. The interface, made of surgically constructed agonist-antagonist muscle pairs that restore natural proprioception (the ability to sense limb position and movement), resulted in improved walking control in a clinical trial involving 14 people with below-the-knee amputation. The findings suggest that even partial reinstatement of neural signaling may be sufficient to enable improvements in neuroprosthetic functionality.

Physical activity, inflammation tied to age-related skeletal changes
New research indicates that some age-related changes in gene and protein expression in the skeletal muscles of older individuals may be affected more by physical inactivity and chronic inflammation than aging alone. This intriguing finding means some aspects of aging may be changeable, or soon will be.

Tech Talk: Samsung hip-assist robot boosts older-adult fitness
Age-related loss of muscle mass, particularly in the legs, often leads to a gradual decrease in physical activity among older adults, as the weakening of lower-limb muscles heightens the risk of falls. However, "a strategic blend of aerobic and balancing exercises" has the potential to not only enhance physical function but also mitigate the risk of falls in older adults, say researchers from Samsung Electronics Co., Ltd., (Suwon, Republic of Korea).

Same-level workplace falls set to rise
Same-level falls in the workplace are set to rise due to the rapid growth in the numbers of older female employees in the workforce, Australian research suggests. Although workplace falls, overall, are more common among male employees, particularly falls from height, same-level falls are more common in older women, the findings indicate. The prevalence and relative severity of workplace falls mean that better prevention strategies are needed to mitigate these sex-specific risk factors, the researchers conclude.

Mild COVID-19 can raise odds of worsening mobility two-fold
A study of data from close to 3,000 Canadian individuals ages 50 and older (51% women) from the beginning through the first nine months of the pandemic revealed that mild-to-moderate COVID-19 was associated with close to a two-fold greater odds of worsening mobility and functioning, even among those who were not hospitalized. Active aging organizations might want to take this into consideration as constituents recover from the illness.
