Background: Neonatal brachial plexus palsy (NBPP) results in muscle weakness and impaired somatosensory function of the arm. Current functional assessment is primarily based on clinician-elicited measurements including muscle strength and range of motion. To what extent these measures are representative of real-world arm movement is unclear. Objective: To determine the feasibility of using body-worn accelerometers to remotely assess arm movements in children with NBPP. Design: Prospective criterion validity study of accelerometry versus clinician assessment. Setting: Academic medical center. Participants: Nine adolescents with NBPP and nine age-and gender-matched control adolescents participated in the study. All were enrolled in school and participated in community activities.Interventions: Not applicable. Methods: Standard clinician-elicited measurements were collected. For assessing spontaneous arm movements, participants wore activity monitors during all waking hours for 7 days. Results were expressed as ratios of affected to unaffected arm motion for duration and magnitude and correlated with traditional clinic-based assessments. Spearman correlations were used to determine relationships between accelerometry results and traditional assessments. A p value <.05 was considered statistically significant. Main Outcome Measurements: Accelerometry measurements of arm motion and traditional clinical assessments. Results: Compared to control ratios, duration of arm movement and magnitude ratios were reduced in the NBPP group, particularly for arm magnitude due to reduced affected arm movement and an increase in unaffected arm movement. Ratios were highly correlated with shoulder function and, to a lesser extent, with elbow function. Conclusion: Real-world arm use is an appropriate outcome measure that reflects functional recovery. This study demonstrates the feasibility of wearable technology to quantify duration and intensity of spontaneous arm movement in children with NBPP. Accelerometry also allows for the association between traditional clinician-elicited assessment measures and spontaneous arm movements, demonstrating the importance of the shoulder as a focus of treatment in NBPP.

Homebound older adults represent an understudied population who are at greater risk of losing hand strength and manipulation skills that, in turn, can lead to increased disability and cognitive declines (Dayanidhi and Valero-Cuevas, 2014). The Hands and Health at Home program was developed through a partnership with the University of Michigan’s School of Kinesiology and Michigan Medicine’s Ann Arbor Meals on Wheels program to demonstrate the feasibility of an intergenerational approach to address unmet needs of Meals on Wheels recipients. Undergraduate movement science student trainers were paired with a client who they visited twice weekly for 5 weeks. Students received training, including mock training scenarios, from an interprofessional team with backgrounds in social work, nursing, and neurorehabilitation. Home training protocols were developed using commercially available games and occupational therapy tools with the aim of improving hand function and facilitating socialization. Pre- and post-assessments included hand strength and dexterity, and client-reported measures of physical function and self-efficacy. Feedback from clients and students was overwhelmingly positive with several students indicating that the experience had stimulated interest in pursuing gerontology careers. Changes in quantitative assessments were variable across clients although pinch strength increased significantly in the non-dominant hand (p&lt;0.02) and was predictive of measures of self-efficacy (r=.78, p&lt;0.02). To our knowledge, this pilot program is the first of its kind and demonstrates the value of an intergenerational approach aimed at improving quality of life in Meals on Wheels clients, and may be of benefit for other underserved older members of the community.
