Description:	Information about upper extremity (UE) kinematics among healthy people is important for reference in rehabilitation. There is abundance of information on three dimensional UE kinematics during functional movements among people with impairments. However, this information is limited among healthy adults. The aim of the present study was to quantify UE kinematics (range of motion, angular velocity, and angular acceleration of shoulder, elbow and wrist joints) among healthy adults during reaching task. The effects of age and limb dominance on UE kinematics was also examined. In this cross sectional study, 24 younger (age: 22.79±1.06), 24 middle aged (age: 37.25±5.96) and 24 older (age: 63.75±5.45) adults were involved. Four inertial measurement unit wireless sensors were attached on the dominant upper part of the shoulder, upper arm, forearm, and distal part of the hand and followed by the non-dominant limb. Participants were required to reach for a standard size mug placed at 90% of arm length distance on an adjustable table while sitting on a standard size chair. The average range of motion measured were: shoulder flexion (72.34°±1.36), adduction (30.78°±1.61), internal rotation (17.18°±1.42, elbow flexion (41.26°±1.95), pronation (34.92°±1.61), wrist extension (5.47°±0.44) and wrist radial deviation (5.65°±0.83). Two way mixed analysis of variance (ANOVA) showed significant main effect of age on wrist radial deviation range of motions, F(2,69)=8.76, p<0.001, np2=0.20 in which middle aged adults had the largest angle. Significant main effect of age was found on angular velocity measurements of shoulder, F(2,69)=6.94, p<0.01, np2=0.17; elbow, F(2,69)=6.89, p<0.01; np2 =0.17; and wrist, F(2,69)=6.49, p<0.01, np2=0.16. A significant main effects of age was also found for angular acceleration of shoulder, F(2,69)=8.27, p<0.001, np2=0.19; elbow F(2,69)=17.77, p<0.001, np2=0.34; and wrist, F(2,69)=5.10, p<0.01, np2=0.13. However, no significant main effects of limb dominance on UE kinematic measurements were demonstrated. These results suggest that clinicians should take clients’ age into consideration instead of limb dominance during UE functional training as UE velocity and acceleration are affected by age.
