“…However, the results of the present study are contrary to studies that did not show proprioceptive asymmetry between joints on the right and left sides of the body (Roy and MacKenzie 1978; Waddington and Adams 1999a; Bullock-Saxton et al 2001; Naughton et al 2002; Han et al 2011). The lack of asymmetry in proprioceptive matching tasks has been largely attributed to differences in methodology, since active generation of target position in a criterion movement, for subsequent reproduction, has been thought to provide movement-related information that may enhance the matching performance of the preferred limb joint (Goble et al 2006).…”

“…Studies using the same movement discrimination method did not find limb asymmetry (Waddington and Adams 1999a; Naughton et al 2002; Han et al 2011), presumably because side preference was not the main focus of the studies, and the degree of limb preference was not controlled. The present study controlled for the degree of both handedness and footedness and found that, for individuals with a strong right side preference, proprioceptive ability of the joints on the non-preferred/left side was consistently better than the joints on the preferred/right side.…”

Proprioceptive performance of bilateral upper and lower limb joints: side-general and site-specific effects

Superiority of the left upper limb in proprioception tasks performed by right-handed individuals has been attributed to better utilization of proprioceptive information by a non-preferred arm/hemisphere system. However, it is undetermined whether this holds for multiple upper and lower limb joints. Accordingly, the present study tested active movement proprioception at four pairs of upper and lower limb joints, after selecting twelve participants with both strong right arm and right leg preference. A battery of versions of the active movement extent discrimination apparatus were employed to generate the stimuli for movements of different extents at the ankle, knee, shoulder and fingers on the right and left sides of the body, and discrimination scores were derived from participants’ responses. Proprioceptive performance on the non-preferred left side was significantly better than the preferred right side at all four joints tested (overall F1, 11 = 36.36, p < 0.001, partial η2 = 0.77). In the 8 × 8 matrix formed by all joints, only correlations between the proprioceptive accuracy scores for the right and left sides at the same joint were significant (ankles 0.93, knees 0.89, shoulders 0.87, fingers 0.91, p ≤ 0.001; all others r ≤ 0.40, p ≥ 0.20). The results point to both a side-general effect and a site-specific effect in the integration of proprioceptive information during active movement tasks, whereby the non-preferred limb/hemisphere system is specialized in the utilization of the best proprioceptive sources available at each specific joint, but the combination of sources employed differs between body sites.

“…Thus, the apparatus permitted testing with participants in a functional posture, making movements similar to those in overhead sports. A previous study of unimanual discrimination performance after arm-raising to contact one of five variable locations overhead used the same apparatus and showed no significant difference in JND between the dominant and nondominant arms (Naughton, Adams, & Maher, 2002).…”

The experimenters examine upper limb movement discrimination performance in an arm-raising task for bilateral associations of low-level unilateral performance. On a cue from the experimenter, young adults (n = 23) with no history of shoulder injury raised either their left arm, right arm, or both together in a forward flexion movement until their hand or hands contacted an unseen, adjustable, overhead stop. The participant then judged which of the 5 possible stop positions, in the 12-20 degrees range forward of true vertical, the participant had contacted on the particular trial. Results showed that for the 16 participants whose best performance was in 1 of the unimanual conditions discrimination scores in the bilateral condition were equivalent to those of their worse-performing limb. For the 7 participants whose best discrimination performance was obtained on bimanual arm-raising, scores for the 2 unimanual conditions were equivalently low. Therefore, when a single limb that can perform well operates in conjunction with a limb performing at a lower level, the consequence is lowering the bimanual movement discrimination performance.

“…Shoulder JPS was assessed with a purpose-built shoulder AMEDA shown in Figure 1. The AMEDA was configured for active proprioception testing (Naughton, Adams, & Maher, 2002; and adapted so that it could be used to assess athletes both in-water and on-land. The apparatus consisted of a contact plate attached to the end of a hand-driven shaft used to set the stop point for the hand when moving backwards with the elbow flexed to 90° and shoulder externally rotated to 75°.…”

Throwing performance in water polo is related to in-water shoulder proprioception Water polo players require a high level of upper-extremity strength, flexibility and coordination to achieve a peak level of throwing performance. Increased levels of shoulder proprioceptive acuity, strength and range of motion (ROM) have been previously associated with higher sporting performance. A coachrating scale, used to quantify an athlete's kicking proficiency in soccer; was adapted in the current study to measure each coach's subjective expert opinion regarding athletes' throwing mechanics, velocity, and accuracy. To examine this hypothesis shoulder proprioception acuity of 18 water polo players was measured both in-water and on-land using an AMEDA apparatus and correlated with coach-rated throwing performance and clinical measures of shoulder strength and ROM. There was a moderate positive correlation between the in-water and the on-land proprioception acuity (r = 0.47, p < 0.05). The in-water score showing a strong positive correlation with coach rated throwing mechanics (r = 0.68, p < 0.05) and velocity (r = 0.75, p = 0.02), suggesting that superior proprioception acuity contributed to fast, mechanically-efficient throwing. These findings support the notion that inwater proprioceptive acuity is an important determinant of the throwing performance achieved by water polo athletes and its measurement may be a valuable adjunct to current athlete screening.
