Description
Background: The functional range of motion is defined as the minimum motion necessary to comfortably and effectively perform a task. Wrist range of motion for activities of daily living has been previously studied. However, maximum and minimum values necessary to complete contemporary tasks such as using a tablet or a smartphone has not been studied.
Methods: Ten healthy adult subjects (five male and five female) participated. Among the subjects were two left-hand dominate males and two left-hand dominant females with the remaining being right-hand dominant. The average age (and standard deviation) was 28+/-1.4 years. All were in good health without any history of upper extremity musculoskeletal disorder. Radiographs were not utilized. Dominant and non-dominant wrists were tested for all subjects. A three-dimensional motion analyzer, CODA system (Codamotion system, Codamotion Charnwood Dynamics Ltd, Leicestershire, UK), using eight optical markers were used in a single laboratory during data collection to record flexion-extension and radial-ulnar deviation for four paired tasks using digital versus traditional devices.
Results: Wrist radial deviation was less when using a smartphone to answer a call (p=0.0287) and texting (minimum p= 0.0002; maximum p=0.0053). In addition, wrist radial-ulnar deviation was less when using a tablet to swipe backwards minimum (p=0.0207). More motion was seen when using the nondominant hand versus the dominant hand in texting (p=0.0386), swiping forward (p=0.0040), and swiping backwards (p=0.0065).
Conclusions: This study focused on the functional range of motion of the wrist in the digital age. It is the first to look at the wrist motion and digital devices. In addition, it is the first to compare wrist motion performing contemporary tasks using digital versus traditional devices. Overall, less wrist motion was used to perform contemporary tasks involving a smartphone and/or a tablet.
Level of Evidence: Clinical Relevance
