Quantifying the Impact of C7 Spinal Nerve Harvest on Spontaneous, Patient-Initiated Movement of the Donor Upper Extremity.

Background: Transfer of a healthy C7 spinal nerve is a tool for upper extremity reanimation in patients with severe brachial plexus injury (BPI). Its use remains controversial owing to concern for neurological injury to the donor arm. Utilizing wearable motion-sensor technology, we aimed to quantify donor arm morbidity after C7 spinal nerve harvest in patients with pan-BPI, reporting both the time and magnitude of donor arm movement in a real-world setting compared to healthy controls.

Effectiveness of a home training program on improving pinch force perception in older adults.

Background: Hand function is reduced with aging which can lead to impairments in the performance of daily activities and eventually loss of independence. The ability to perceive the forces being applied to an object is an important component of hand control that also declines with age. However, the extent to which force perception can be improved through training remains largely unknown.

Racial/Ethnic Differences in Self-Reported Upper Limb Limitations Among U.S. Older Adults.

Background: The development of disability related to activities of daily living (ADL) is of great concern in the aging population, particularly for Hispanic and Non-Hispanic (NH) Black older adults, where disability prevalence is greater compared to NH Whites. ADL-disability is typically measured across many functional tasks without differentiating upper- versus lower-limb limitations, hindering our understanding of disability burden. Despite the importance of the upper limbs for completing ADL and known age-related declines in function, racial/ethnic differences in upper limb function remain largely unknown.

An intergenerational service-learning approach to improve hand function in older adults.

Homebound older adults are at greater risk for functional impairments, social isolation, and loss of independence. Adequate hand function is needed to perform many daily activities, yet is understudied, particularly in the homebound population. The purpose of this study was to pilot test an intergenerational program in which pre-health college students were trained to deliver hand exercises to homebound older adults receiving Meals on Wheels (MOW) services.
