[Purpose] This study aimed to examine how supporting the knee from the front with a knee pad affected upper-limb dexterity while sitting. [Participants and Methods] A total of 14 healthy adult males were included in the study. As a measure of upper-limb dexterity, the number of pins was counted when the Purdue pegboard test was performed for 60 seconds. In addition, the ease of task performance was assessed using the visual analogue scale. There were two experimental conditions, with and without knee pad. The paired t-test was used to detect differences between the two conditions. A p-value of 0.05 was considered statistically significant. [Results] The Purdue pegboard test was 29.4 ± 2.5 and 27.9 ± 3.6 pins with and without knee pad, respectively. The VAS was 76.1 ± 10.3 and 62.9 ± 14.1 with and without knee pad, respectively. Both measured values were significantly higher with knee pad than without. [Conclusion] Supporting the knees from the front with knee pad improves upper-limb functionality while sitting, making it easier to perform seated tasks.
