| dc.description.abstract | Despite the increased prevalence of shoulder abnormalities with age, no identified study had analyzed the effect of age on shoulder joint proprioception. Based on previous research of proprioceptive changes at other upper extremity joints, our primary hypothesis was that older individuals would experience decreased shoulder joint proprioception when compared to younger individuals. We tested joint reposition accuracy in subjects aged 18-25 with an iPhone application designed to measure joint position sense. We obtained data regarding joint reposition accuracy in individuals aged 48- 55 from the 2012 American Society of Biomechanics Annual meeting. We detected no significant influence of age on constant error (p=0.456) or variable error (p=0.106). We secondarily worked to affirm previous claims that shoulder flexion angle affects repositioning accuracy. Our secondary hypothesis was that individuals would demonstrate greater repositioning accuracy as the target flexion angle increased from 0° to 90°. We detected significant influence of target angle on constant error (p=0.001). We detected no significant influence of target angle on variable error (p=0.106). | en_US |
