“…For each test, a purpose-built AMEDA, used in previous studies, was employed at four body sites: the ankle (Waddington and Adams 1999b; Waddington et al 1999; Symes et al 2010), knee (Waddington and Adams 1999a; Waddington et al 2000), shoulder (Naughton et al 2005; Vulcetic et al 2008) and fingers (Han et al 2011) (Fig. 1a).…”

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.

“…A battery of versions of the Active Movement extent Discrimination Apparatus (AMeDA) that had been used in previous studies was employed at 5 body sites: the ankle (Waddington & Adams, 1999b;Waddington, Adams, & jones, 1999;Waddington & Adams, 2004), knee (Waddington & Adams, 1999a;Waddington, Seward, Wrigley, lacey, & Adams, 2000), spine (hobbs, Adams, Shirley, & hillier, 2010;hobbs, Adams, Waddington, & hillier, 2011), shoulder (naughton, Adams, & Maher, 2005vulcetic, holmes, Adams, & Waddington, 2008;Whiteley, Adams, nicholson, & Ginn, 2008), and fingers (Han, Waddington, Anson, & Adams, 2011). reliability for the ankle AMeDA has been determined as 0.89 (Waddington & Adams, 2004) and 0.85 for the finger pinch AMEDA (Han, et al, 2011) .…”

Ability to Discriminate Movements at Multiple Joints around the Body: Global or Site-Specific

This study tested whether proprioceptive discrimination of movement is a global, general ability, or an attribute that is specific to the joint tested. 40 right-handed, healthy, young adults (19 men, 21 women; M age = 20.4 yr., SD = 1.7) volunteered. A battery of versions of the Active Movement Extent Discrimination Apparatus (AMEDA) were employed to generate the stimuli for movements of different extents at the ankle, knee, spine, shoulder, and finger; discrimination accuracy scores were derived from participants' responses. No significant correlations were found between the discrimination scores from the five sites (all rs < or = .21, all ps > or = .20). This finding extends a previous report of non-significantly correlated proprioception test scores at two lower limb sites, and the findings taken together suggest that rather than proprioception being a global, general ability, sensitivity to the proprioception that underlies movement control is site-specific.

“…Using this psychophysical approach to measure active, functional movement discrimination ability, Waddington and Adams [9] developed special equipment (Active Movement Extend Discrimination Apparatus (AMEDA)) to assess subjects' ability to discriminate active ankle movements. After the apparatus designed to test discrimination of the extent of ankle inversion, subsequent devices have been developed to assess joint position resolution at the knee [10,11], the hip [12,13], the spine [14] and the shoulder [15][16][17].…”

Proprioception provides feedback that is vitally important for motor control. A deficiency in joint proprioception is thought to be associated with various upper limb rheumatological disorders. Currently, there is a lack of a portable device that could be used for measuring functional proprioception at the fingertips in the field. Therefore, a novel portable device for measuring pinch movement discrimination between index finger and thumb of either hand was constructed. This device is manually operated and requires the subject to make an absolute judgment of a joint position, choosing which one of five pre-experienced positions is being presented to them, with trials given in a random order. The 5 physical differences used were between 1.22 and 2.42cms. Reliability analysis was performed over a 7-day interval, with 8 healthy young adult volunteers. The discrimination scores, measured as the Area Under the Curve (AUC), for the group showed a mean (SD) of 0.794 (0.544) and 0.794 (0.549) on days 1 and 8, respectively. The day 1 and 8 reliability assessed with the interclass correlation coefficient ICC(3,1) was 0.85. Nondominant hands showed better pinch discrimination on the two days, with AUC values of 0.800 and 0.810 compared with 0.788 and 0.778, but these differences were not statistically significant (p>0.05). No difference in pinch movement discrimination was found between sexes. The ease of use and portability of the novel device for measuring functional proprioception at the fingertips described in this note make it ideal for measuring hand functional proprioception as part of clinical and epidemiological studies. The mid-range AUC discrimination scores found with healthy young adults mean that factors thought to diminish (eg. hand injury) or improve (eg. having expert finger skills) discrimination could be detected with the device.
