title: Radial nerve measurements in nonsymptomatic upper extremities of Filipinos: A cross-sectional study.
abstract: BACKGROUND
  Despite reports on the association of radial nerve (RN) size and lateral epicondylalgia (LE), Filipino normative values on RN size in healthy elbows are not established. An association with upper extremity anthropometric measurements is likewise not reported.
  
  
  METHODS
  Musculoskeletal ultrasound measurements of the RN at the level of the lateral epicondyle (RN-LE), posterior interosseous nerve at the level of the radial head and supinator (PIN-RH and PIN-sup), and superficial RN (SRN) in the elbows of healthy Filipinos were made in Manila from January-September 2011.
  
  
  RESULTS
  A total of 198 elbows of 99 healthy participants aged 43 years (range, 33-48 years) [median(IQR)] were investigated. Men have larger PIN-RH, PIN-sup, and SRN compared with women. Arm length was associated with PIN-RH, PIN-sup, and SRN (P < 0.05). Activities and elbow circumference measurements (at 2 levels) were associated with PIN-RH.
  
  
  CONCLUSIONS
  RN reference values can now be used for comparison in elbows with LE.
