A comparison of hand function in Colles and scaphoid casts using a modified Jebsen Hand Function Test

This study investigates the impact of Colles versus scaphoid casts on hand function in modern day activities using the Jebsen Hand Function Test with additional modified subtests including texting on a mobile phone, using a computer mouse and typing on a computer keyboard. Twenty healthy volunteers were recruited for the study. Study participants performed worse in a scaphoid cast compared to a Colles cast; most evident in tasks involving fine motor movements such as writing, picking up small objects and stacking checkers (mean time difference 2.3 seconds, 1.5 seconds and 1.2 seconds, respectively) and tasks involving forearm rotation such as card turning and picking up large light objects (mean time difference 1.6 seconds and 1.1 seconds, respectively). This study highlights the importance of careful consideration when assessing the need for thumb immobilization, due to its impact on hand function when performing both traditional and modern-day activities of daily living.
