| Abstract: | [Purpose] The study investigated the effects of joint position on the distractiondistance during Grade III glenohumeral joint distraction in healthy individuals. [Subjectsand Methods] Twenty adults in their forties without shoulder disease were randomly dividedinto neutral position group (NPG; n = 7), resting position group (RPG; n = 7), and endrange position group (ERPG; n = 6). After Kaltenborn Grade III distraction for 40s, thedistance between glenoid fossa and humeral head was measured by ultrasound. [Results] Theaverage distances between the humeral head and glenoid fossa before distraction were 2.86± 0.81, 3.21 ± 0.47, and 3.55 ± 0.59 mm for the NP, RP, and ERP groups. The distancesafter applying distraction were 3.12 ± 0.51, 3.86 ± 0.55, and 4.35 ± 0.32 mm.Between-group comparison after applying distraction revealed no significant differencesbetween the NP and RP groups, while there was a statistically significant differencebetween the NP and RP groups, as well as between the NP and ERP groups. [Conclusion] Jointspace was largest in ERP individuals when performing manual distraction.Key words: Joint position, Manual distraction, Glenohumeral joint |
