METHODS In this cross-sectional study, a total of 46 older persons were divided into a T2DM group(n = 23) and a control group who did not have T2 DM(n = 23). Participants were given a brief warm up with stretching exercises. Diabetic neuropathy scores were collected prior to proprioceptive testing. For proprioceptive testing, participants performed leg extensions to randomized target positions of 15°, 30°, 45, 60° degrees of elevation in the sagittal plane, each target was repeated a total of four times. Subjects were guided to target positions in the absence of visual feedback via auditory cues from a custom JPS application. When the participant entered the target position, they memorized the location of their limb in space and subsequently attempted to relocate this position in space. Proprioceptive errors were measured from the target positioned, target remembered, target repositioned protocol. RESULTS Proprioceptive accuracy was lower in the diabetic groupat all levels of target angle than the control group(P < 0.05). The diabetic group had 46% greater inaccuracy than the control group at all levels of target position. Diabetics also reported greater neuropathy scores than controls in the past 12 mo P < 0.01. CONCLUSION Deficits in lower limb localization and greater diabetic neuropathy scores were identified in this study. Our findings may be associated with deafferentation as peripheral neuropathy is a common complication with the disease. These findings may help to explain the declining balance function in the older persons with T2DM which is also commonly reported.展开更多

It is reported that the postoperative dislocation often occurs by the posterior approach of the THA and may be caused by functionality instability due to the injury of the periarticular soft tissue. We analyzed the joint position sense of the hip according to an approach of the THA and examined effect to give postoperative dislocation. Materials & Methods: 92 patients (184 hip joints) who received THA in our hospital were selected in the study. Cases in which position sensation measurements were insufficient were excluded. As for the classification, the posterior approach (PL groups) was 39 hips, anterolateral approach (AL groups) was 30 hips, and control group was 37 hips. Results: There was no significant difference between the AL group and PL group in the absolute reproduction angle error score (ARAES). The relative reproduction angle error scores (RRAES) for passive internal and external rotations and active internal rotation were significantly lower in the AL and control groups than the PL group. Discussion: This study was suggested that the hip joint position sense in the AL group was better retained for the preservation of the soft tissue.展开更多

文摘Introduction: The instability of the joint is classified roughly into mechanical and functional. It is reported that the postoperative dislocation often occurs by the posterior approach of the THA and may be caused by functionality instability due to the injury of the periarticular soft tissue. We analyzed the joint position sense of the hip according to an approach of the THA and examined effect to give postoperative dislocation. Materials & Methods: 92 patients (184 hip joints) who received THA in our hospital were selected in the study. Cases in which position sensation measurements were insufficient were excluded. As for the classification, the posterior approach (PL groups) was 39 hips, anterolateral approach (AL groups) was 30 hips, and control group was 37 hips. Results: There was no significant difference between the AL group and PL group in the absolute reproduction angle error score (ARAES). The relative reproduction angle error scores (RRAES) for passive internal and external rotations and active internal rotation were significantly lower in the AL and control groups than the PL group. Discussion: This study was suggested that the hip joint position sense in the AL group was better retained for the preservation of the soft tissue.
