Reduced shoulder proprioception due to fatigue after repeated handball throws and evaluation of test–retest reliability of a clinical shoulder joint position test

Background Proprioception is vital for motor control and can be disturbed, example, due to fatigue or injury. Clinical feasible, reliable valid tests of shoulder proprioception are warranted. The aim was investigate the effects local on reliability a feasible joint position sense test using an experimental repeated measures design. Method Forty participants assess test–retest reliability. then utilized subgroup handball players who were subjected five bouts throwing task with dominant hand. effect investigated by comparing fatigued non-fatigued shoulder. Results There significant interaction arm × bout ( p = 0.028, η 2 0.20) 0.034, 0.35) decrease in compared non-throwing arm. intraclass correlation coefficient 0.78 (95% CI [0.57; 0.89]). standard error measurement between trials 0.70° (range: 0.57°–0.90°). Discussion results indicate that disturbs sense. Assessment modified showed acceptable valuable assessment tool clinic.
