AIM To investigate proprioceptive discrepancies in the lower extremity in persons with type 2 diabetes mellitus(T2DM). 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.

OBJECTIVE: To determine the effects of Taijiquan practice on knee proprioception in patients with knee osteoarthritis(OA).METHODS: We conducted a randomized controlled trial comparing Taijiquan with a control condition(wellness education) in patients with knee OA. The patients participated in either a 60-min Taijiquan session three times weekly or a 60-min weekly educational session, for 24 consecutive weeks. The primary outcomes were changes in knee proprioception. Secondary outcomes were changes in the Western Ontario and Mc Master University Osteoarthritis Index(WOMAC).RESULTS: After 24 weeks, compared with the control group, the Taijiquan group demonstrated better improvements in the joint position sense in knee flexion(left:-2.12°; right:-2.02°), and knee extension(left:-2.22°; right:-1.54°). In addition,the Taijiquan group showed significantly greater improvements in the WOMAC scores(P proprioception in patients with knee OA. The present findings add increasing evidence regarding the clinical benefits of Taijiquan as a therapeutic modality for patients to improve the reflex protection of knee joints against potentially harmful forces.

Background Our previous studies have shown that electrical stimulation from the skin surface to the tendon region(Tendon Electrical Stimulation:TES)can elicit a force sensation,and adjusting the current parameters can control the amount of the sensation.TES is thought to present a proprioceptive force sensation by stimulating receptors or sensory nerves responsible for recognizing the magnitude of the muscle contraction existing inside the tendon,so it can be a proprioceptive module of a small-size,low-cost force feedback device.But there is also suspect that TES presents only strong,noisy skin sensation.From previous study,it was found that TES has some limitation on varying sensations.Methods In this study,in addition to characterizing the proprioceptive sensation induced by TES,we constructed a multimodal presentation system reproducing a situation in which force is applied to the hand was offered,so as to investigate whether TES contributed to the reproduction of haptics cooperating with other modalities,rather than disturbing them.Specifically,we used vibration to present a cutaneous sensation and a visual head mounted display(HMD)system to present simultaneous images.Using this system,we also evaluated the efficacy of TES itself and that of the multimodal system involving TES.Results We found that TES,along with visual and vibration stimulation,contributed to the perception of a certain force.Conclusions Thus,TES appears to be an effective component of multimodal force sense presentation systems.

It is known that anterior cruciate ligament(ACL) reconstruction needs to be combined with detailed postoperative rehabilitation in order for patients to return to their pre-injury activity levels, and that the rehabilitation process is as important as the reconstruction surgery. Literature studies focus on how early in the postoperative ACL rehabilitation period rehabilitation modalities can be initiated. Despite the sheer number of studies on this topic, postoperative ACL rehabilitation protocols have not been standardized yet. Could common, "ossified" knowledge or modalities really prove themselves in the literature? Could questions such as "is postoperative brace use really necessary?", "what are the benefits of early restoration of the range of motion(ROM)?", "to what extent is neuromuscular electrical stimulation(NMES) effective in the protection from muscular atrophy?", "how early can proprioception training and open chain exercises begin?", "should strengthening training start in the immediate postoperative period?" be answered for sure? My aim is to review postoperative brace use, early ROM restoration, NMES, proprioception, open/closed chain exercises and early strengthening, which are common modalities in the very comprehensive theme of postoperative ACLrehabilitation, on the basis of several studies(Level of Evidence 1 and 2) and to present the commonly accepted ways they are presently used. Moreover, I have presented the objectives of postoperative ACL rehabilitation in tables and recent miscellaneous studies in the last chapter of the paper.

This study was designed to investigate the effects of kinesio tape (KT) on functional performance of female basketball players with and without chronic ankle instability (CAI). The players with (n = 15) and without ankle instability (n = 16) were enrolled. KT was applied with tension in the instability group and without tension in the control group. Before KT application, 30 minutes and 48 hours after application; muscle strength and endurance were tested in plantar flexion and dorsiflexion, joint position sense was measured in ankle dorsiflexion and plantar flexion using a dynamometer. Dynamic postural stability was evaluated with a balance system between the levels of 12-4. Vertical jumping heights were measured by jump-meter. The results were statistically assessed by SPSS 19 version. In CAI group, dynamic postural stability showed statistically significant improvement in both legs overall (P < 0.0001), antero-posterior (P < 0.004) and medio-lateral indexes (P < 0.009). CAI group showed significant improvements in one-leg postural stability overall, antero-posterior and medio-lateral indexes after 48 hours (P < 0.011, P < 0.022, P < 0.038, respectively). Joint position sense, vertical jump height and muscle strength and endurance were also compared in both groups, and there was no significant difference between the groups. Postural stability indexes were decreased by supporting function of KT to the ankle. As a result, we can say that KT has a beneficial effect on maintaining posture by correcting standing kinematics in cases with CAI. We may suggest that KT can be utilized in preventing the injuries in CAI.

Lateral ankle sprain is a common orthopedic injury with a very high recurrence rate in athletes. After decades of research, it is still unclear what contributes to the high recurrence rate of ankle sprain, and what is the most effective intervention to reduce the incident of initial and recurrent injuries. In addition, clinicians often implement balance training as part of the rehabilitation protocol in hopes of enhancing the neuromuscular control and proprioception of the ankle joint. However, there is no consensus on whether the neuromuscular control and proprioception are compromised in unstableankles. To reduce the prevalence of ankle sprains, the effectiveness of engaging balance training to enhance the neuromuscular control and proprioception of the ankle joint is also questionable.

橡胶手错觉是一种健康个体将非肉体的假手视为自己真实身体的一部分的体验，这种错觉可以通过同时轻刷被试面前可见的橡胶手及其不可见的真手而产生。橡胶手错觉已成为一种研究身体拥有感的重要范式，其产生机制可以分为“自下而上的认知匹配”与“自上而下的认知匹配”两种加工方式。前者涉及视觉与触觉刺激的同步性；而后者涉及被试心中预存的身体意象与身体图式(包括真假手之间模态特征、位置空间的相似性)。综合上述证据，身体模型假说与个人边缘空间理论进一步为拥有感产生的复杂机制提供了整合两种加工方式的解释。橡胶手错觉范式已经被用于探索精神分裂症患者等特殊被试病理分析、错觉产生和心理特质之间的关系，以及神经外科和术后恢复上。未来的研究应该更加重视范式本身的拓展，应用虚拟现实技术来提高身体模态的仿真效果，利用橡胶手拥有感的易感性作为筛选与预测身体意象障碍疾病的指标。
