Mid-upper arm circumference and nutritional risk in macrocephalic pediatric patients
… study is to determine if the measurement of mid-upper arm circumference (MUAC) in pediatric patients with macrocephaly better identifies children at nutritional risk as compared to weight-for-length (WFL) or body mass index (BMI). Methods: A cross-sectional pilot study of children aged 6-36 …

Mid-upper arm circumference: a surrogate for body mass index in pregnant women?
… body fat or nutritional state in pregnancy. Mid upper arm circumference has been used for many decades in children under the age of five, to assess malnutrition. Many studies have shown a strong correlation between MUAC and BMI in the adult population. MUAC is a much simpler anthropometric …

Development of a human body upper arm dynamic model for compensation and control of a body mounted robot
… system was developed to model simple human arm reaching motions. From this simulated system, a set of virtual measurements were made to construct input/ output data sets. Subspace identification applied to these data sets indicated the applicability of the approach. Further testing was then …

Three-Dimensional Analysis of the Development of Upper Arm Musculoskeletal Stress Markers in Late Adolescents and Young Adults of Archaic and Mississippian Populations of Tennessee
… and fractal analysis The morphology of 19 upper limb attachment sites was observed in 33 males aged 15 and 30+ years, dating to the Archaic and Mississippian periods from the southeastern U.S. It was hypothesized that 1) the microscopic method would identify subtler differences than the …

The double burden of malnutrition in South Africa: risk factors for undernutrition and overnutrition and the development of a novel mid-upper arm circumference (MUAC) screening tool in children
The World Health Organisation has produced recommendations for screening for malnutrition in childhood. However, evidence is emerging that the performance of these tools is region-specific. The aim of this set of six studies were to identify contextual factors which contribute to childhood …

Estimation of distal arm joint angles from EMG and shoulder orientation for transhumeral prostheses
… studies have shown that shoulder orientation and upper-arm electromyography (EMG), taken separately, are predictors of both elbow flexion/extension and forearm pronation/supination during arm movements. In this thesis, we quantify the extent to which shoulder orientation, upper-arm EMG, and …

Design of a spring-integrated crutch for ascending stairs
Using conventional underarm or forearm crutches is uncomfortable and awkward. Further, underarm crutches make climbing stairs difficult and unsafe. One may climb stairs with forearm crutches, which do not impede elbow movement, but doing so is fatiguing and requires upper body strength. In 2011, …
