“…The highly innervated dorso-radial ligaments are highly involved during AA, while the less innervated volar ligaments get primarily stressed during FE and PS. These differences in mechanoreceptor density and innervation might be responsible for the proprioceptive anisotropy reported in our investigation, and find confirmation in previous outcomes obtained by using the same robotic device [16, 50, 51]. …”

BackgroundSeveral neurodevelopmental disorders and brain injuries in children have been associated with proprioceptive dysfunction that will negatively affect their movement. Unfortunately, there is lack of reliable and objective clinical examination protocols and our current knowledge of how proprioception evolves in typically developing children is still sparse.MethodsUsing a robotic exoskeleton, we investigated proprioceptive acuity of the wrist in a group of 49 typically developing healthy children (8–15 years), and a group of 40 young adults. Without vision participants performed an ipsilateral wrist joint position matching task that required them to reproduce (match) a previously experienced target position. All three joint degrees-of-freedom of the wrist/hand complex were assessed. Accuracy and precision were evaluated as a measure of proprioceptive acuity. The cross-sectional data indicating the time course of development of acuity were then fitted by four models in order to determine which function best describes developmental changes in proprioception across age.ResultsFirst, the robot-aided assessment proved to be an easy to administer method for objectively measuring proprioceptive acuity in both children and adult populations. Second, proprioceptive acuity continued to develop throughout middle childhood and early adolescence, improving by more than 50% with respect to the youngest group. Adult levels of performance were reached approximately by the age of 12 years. An inverse-root function best described the development of proprioceptive acuity across the age groups. Third, wrist/forearm proprioception is anisotropic across the three DoFs with the Abduction/Adduction exhibiting a higher level of acuity than those of Flexion/extension and Pronation/Supination. This anisotropy did not change across development.ConclusionsProprioceptive development for the wrist continues well into early adolescence. Our normative data obtained trough this novel robot-aided assessment method provide a basis against which proprioceptive function of pediatric population can be compared. This may aid the design of more effective sensorimotor intervention programs.

[Purpose] To investigate possible cross effects of proprioception training on proprioception repositioning accuracy of the knee joint and on balance in healthy subjects. [Subjects and Methods] Sixty healthy college students and faculty members from faculty of physical therapy, Cairo University were recruited to participate. Participants were randomly assigned to training group (n=30) and control group (n=30). The training group received proprioceptive training program only for the dominant leg while the control group did not receive any kind of training. Outcome measures were twofold: (1) proprioception repositioning accuracy quantified through the active repositioning test for the non-dominant knee; and (2) balance stability indices determined through using Biodex balance system. Measurements were recorded before and after 8 weeks of proprioception training. [Results] There were significant decrease in the error of repositioning accuracy and the stability indices including anterposterior stability index, mediolateral stability index, and overall stability index of training group, measured post training, compared with control group. [Conclusion] Proprioception training has significant cross training effects on proprioception repositioning accuracy of the knee joint and on balance among healthy subjects.

“…Moreover, this allows for optimization of sampling procedure-specific parameter settings for a specific threshold and slope range of the population of interest. So far, experimental results on the difference threshold of angular joint position revealed values ranging from 1 to 5 • , approximately, for elbow, wrist, and finger joints in healthy subjects (Tan et al, 1994;Brewer et al, 2005;Tan et al, 2007;Lambercy et al, 2011;Rinderknecht et al, 2014;Elangovan et al, 2014;Cappello et al, 2015). However, in patients with proprioceptive deficits those values are higher and may go up to around 10 • (Rinderknecht et al, submitted).…”

“…The combination of psychophysical procedures to estimate psychometric functions with robotic technology would offer more reproducible assessments with a higher resolution. There have been few studies exploring this approach for the assessment of the upper limb (Brewer et al, 2005;Tan et al, 2007;Lambercy et al, 2011;Rinderknecht et al, 2014;Simo et al, 2014;Elangovan et al, 2014;Cappello et al, 2015). So far MOCS has been predominantly used, with experiments typically lasting about 45 min (Brewer et al, 2005;Tan et al, 2007;Lambercy et al, 2011;Simo et al, 2014).…”

When estimating psychometric functions with sampling procedures, psychophysical assessments should be precise and accurate while being as efficient as possible to reduce assessment duration. The estimation performance of sampling procedures is commonly evaluated in computer simulations for single psychometric functions and reported using metrics as a function of number of trials. However, the estimation performance of a sampling procedure may vary for different psychometric functions. Therefore, the results of these type of evaluations may not be generalizable to a heterogeneous population of interest. In addition, the maximum number of trials is often imposed by time restrictions, especially in clinical applications, making trial-based metrics suboptimal. Hence, the benefit of these simulations to select and tune an ideal sampling procedure for a specific application is limited. We suggest to evaluate the estimation performance of sampling procedures in simulations covering the entire range of psychometric functions found in a population of interest, and propose a comprehensive set of performance metrics for a detailed analysis. To illustrate the information gained from these metrics in an application example, six sampling procedures were evaluated in a computer simulation based on prior knowledge on the population distribution and requirements from proprioceptive assessments. The metrics revealed limitations of the sampling procedures, such as inhomogeneous or systematically decreasing performance depending on the psychometric functions, which can inform the tuning process of a sampling procedure. More advanced metrics allowed directly comparing overall performances of different sampling procedures and select the best-suited sampling procedure for the example application. The proposed analysis metrics can be used for any sampling procedure and the estimation of any parameter of a psychometric function, independent of the shape of the psychometric function and of how such a parameter was estimated. This framework should help to accelerate the development process of psychophysical assessments.
