BACKGROUND Multiple human experiments have shown that articular lesions can have a negative effect on proprioception. The influence of total elbow arthroplasty on joint position sense has not been reported so far. The purpose of the study was to evaluate proprioception, defined as a joint position sense, after total elbow arthroplasty. METHODS The study included 16 patients with unilateral se...

Age-related changes in lower limb joint position sense and their contributions to postural stability are well documented. In contrast, only a few studies have investigated the effect of age on proprioceptive hand function. Here, we introduce a novel test for measuring joint position sense in the fingers of the human hand. In a concurrent matching task, subjects had to detect volume differences ...

OBJECTIVE To assess joint position sense performance in subacute stroke patients using a novel quantitative assessment. DESIGN Proof-of-principle pilot study with a group of subacute stroke patients. Assessment at baseline and after 2 weeks of intervention. Additional data for a healthy age-matched control group. SUBJECTS/PATIENTS Ten subacute stroke patients (aged 65.41 years (standard dev...

In this article it is shown how the end effector position of a single flexible-link robot can be directly controlled by the angular position of its joint, so that, trajectory tracking in the end effector of the robot is possible by properly designing a reference trajectory for the joint angle. In order to ensure trajectory tracking of the angular position of the robot joint, a Sliding Modes Con...

Background: Anterior Cruciate Ligament) ACL (injury is the most prevalent knee ligament injury during exercise, with a frequency of 36.9 per 100000 individuals. The one characteristic of this injury is proprioception dysfunction. The current study investigated the knee proprioception in soccer players after ACL reconstruction. Methods: The study participants consisted of 20 elite male soccer p...

A joint amplitude and position search procedure is proposed for searching algebraic multipulse codebooks. It is implemented within the reference G.723.1 codec as an example. This joint search method is shown to reduce down to one third the number of comparisons per subframe relative to the focused search over an extensive speech database. An e cient implementation of the joint search is derived...

The objective of this study was to evaluate the effect of negative intra-articular pressure on shoulder joint stability in canine cadavers. Cadaver forelimbs from 12 mature dogs were used. The forelimbs were placed in a testing frame and axially preloaded with 4 kg of weight. Shoulder joint stability was tested in flexion, extension, and neutral position before and after venting of the joint ca...
