Effect of a neoprene sleeve on knee joint kinesthesis: influence of different testing procedures.

PURPOSE: Objectives of this study were to examine the perceived sense of knee joint position during selected test situations, and to evaluate the proposed kinesthetic effect of a neoprene knee sleeve during these test situations. METHODS: Fifty-nine young healthy subjects (39 females and 20 males) attempted to replicate target knee joint angles using active and passive knee extension movements completed in sitting (nonaxially loaded) situations, and during active knee extension movements completed in supine while applying a load of 15% body weight through the long axis of the tibia (axially loaded). The criterion measure used was the absolute difference between target and reproduced angles, averaged over five attempts (Average absolute difference: AAD). RESULTS: A three-way ANOVA (two genders by three test situations by two sleeve conditions), with repeated measures on the last two factors, indicated a significant main effect for test situation and sleeve condition (P < 0.05), but not for gender. There was also a significant test situation by sleeve condition interaction (P < 0.05). Post-hoc analysis indicated that the AAD score during the active nonaxially loaded test situation without the sleeve was significantly greater than AAD scores for all other tests (P < 0.01). CONCLUSIONS: Pre-existing differences in knee joint kinesthesis observed during different contexts of limb movement must be recognized before various interventions, including the effect of knee supports, can be adequately interpreted. Because knee joint position sense was attenuated during voluntary active movement, and because this attenuation was ameliorated by the use of a sleeve, future studies evaluating the kinesthetic effects of knee bracing may benefit from using active movements. However, since the sleeve did not affect performance during the axially loaded test situation, future studies should also evaluate the relationship between tests of knee joint kinesthesis and other more functional tests of neuromuscular performance.

Vision and kinesthesis in spatial short-term memory.

This investigation examined the effects of different localizing cues on the precision with which subjects can recall the position of a target in space. The availability of the cues--vision, kinesthesis, or both--was varied during both learning and recall. Subjects (age range 26 to 58 yr.) placed the stimulus or watched it being placed. The stimulus was removed, and subjects replaced or indicated its replacement location. Results show a striking similarity of performance for all subjects and significant performance differences relative to the different cues. The results provide information about intramodal and intermodal visual and kinesthetic transfer effects and about the effects of unimodal and multimodal input in such transfer. Results confirm a dominance of vision over kinesthesis, i.e., "kinesthetic memory" does not provide as accurate localizing information as does "visual memory."

Figural after-effects in kinesthesis: more data on age differences.

A cross-sectional study of figural after-effects in kinesthesis on 144 subjects ranging in age from 10 to 87 years was carried out. The procedure was nearly identical to one used by Köhler and Dinnerstein (1947). The data show a significant nonmonotonic age trend of the figural after-effect. There is a decline of the kinesthetic after-effect from the youngest to the 35-50-year-old group, followed by an increase in the 51-66-year-olds, and a decrease from this group to the 67-87-year-old group. The pre-test judgments follow a quadratic trend, with a minimal deviation from the objective block size in the group of 35-50-year-old people. The theoretical basis for the relationship between age and figural after-effects is discussed with respect to an age specificity of the attentional capacity, of the cognitive strategy for making successive comparisons, and of stimulus persistence.

The role of the inertia tensor in kinesthesis.

We report experiments directed at the ability of humans to perceive the spatial orientation of occluded objects, to position an occluded limb relative to targets or directions in the environment, and to match the spatial orientation of occluded contralateral limbs. Results suggest that each of these abilities is tied to the inertial eigenvectors of each object or limb, which correspond to the object's or limb's principal axes of rotational inertia. It is suggested that the mechanisms supporting the perception of intact limbs, neuropathic or anesthetized limbs, prosthetic devices, and hand-held tools and implements via kinesthesis may be one and the same--the detection of movement-produced physical invariants such as the inertia tensor. While the research reported presently has focused on the perception of intact limbs and hand-held objects, future research should be directed at possible generalizations of this work to a variety of clinical populations, including those involving peripheral neuropathies and prosthetic devices.

Vision and kinesthesis in accuracy of hand movement.

Two experiments examined the accuracy with which college students were able to touch a target when knowledge of the target location had been gained either visually, kinesthetically, or by both modalities. In all but "baseline" trials, individuals were not allowed to guide the hand visually and so relied on kinesthetic cues during movement to the target location. No feedback was provided. Contrary to students' expectations, accuracy of the movements was greater when the target location had been given kinesthetically (passive movement to the target) as opposed to visually. When target location was provided by seeing one's hand move to the target (kinesthetic plus visual), performance was slightly poorer (though nonsignificantly) than for the purely kinesthetic condition, but significantly better than for a purely visual target condition. These results are discussed in terms of visual dominance and the roles of vision and kinesthesis in guiding normal hand movements.

[Measuring knee joint kinesthesis for determining proprioceptive deficits in varus gonarthrosis].

Studying knee osteoarthrosis proprioceptive deficits play a growing role. However, the methods for the detection of these deficits using joint position sense measurements have been criticized recently. Therefore, we developed a new method for the measurement of knee-joint kinaesthesia. At 5 different angular velocities of passive knee movement both movement and stop detection were tested. Tests were performed both in 25 patients with osteoarthrosis of the knee and in a control group of 20 age related normal subjects. In addition to the measurements of movement detection and stop-detection thresholds, a specific detection-failure analysis was performed in our study. In addition to a significant improvement of proprioceptive abilities with increasing angular velocities, detection failure analysis brought about significant differences between patients with knee osteoarthrosis and normal subjects yielding a significant proprioceptive deficit in osteoarthrosis of the knee. In contrast, in case of correct movement detection or stop-detection there were no significant differences in the detection-threshold values between normal and ostheoarthrotic knees. In conclusion, both the lack of differences in detection thresholds between the arthrosis and the control-groups and the increased detection failure rates in arthrosis patients gave evidence for these proprioceptive differences being a result of central nervous dysregulation in knee osteoarthrosis.

Some contributions of touch, pressure and kinesthesis to human spatial orientation and oculomotor control.

Human spatial orientation and oculomotor control are under multimodal influence. It is not possible in the normal animal to stimulate differentially the vestibular receptors without activating other receptor systems whose activity may have a profound influence on postural control and experienced orientation. Many patterns of behavior and response that have been attributed solely to vestibular function are actually dependent wholly or in part on touch, kinesthetic, and proprioceptive stimulation.

[Quality and quantitative comparison of health status during nursing care before and after basic kinesthesis training in a nuclear and radiotherapy clinic].

UNLABELLED: Immediately before and half a year after an introductory course into the principles of kinesthetic nursing the nursing team of the Clinic for Nuclear Medicine and Radiotherapy, City Hospital Triemli (Zurich, Switzerland), was asked to attend a semi-structured interview and nonverbal rating of a selection of important aspects of their physical and mental state during nursing. Eighteen persons had two interviews. The main differences in the second interview compared to the first one are the following: With respect to personal aims at work caring for the patients' well-being had fewer mentions; instead nursing was more often considered a process to which both sides do contribute significantly. Considerable improvements were found regarding to the physical contact to patients while caring, the team, and the nurses' general mental well-being. Physical benefits from the new nursing method were experienced only by part of the team, probably due to unplanned cancelling of kinesthetic supervision. Pressure due to the nurses' compassion for their patients' suffering and dying also was much less mentioned in the second interview, when pressure from outside, and lack of interdisciplinary communication and cooperation weighted more heavily. INTERPRETATION: Competence was already high in the team at the time of the first interview, but even improved by the time of the second interview. This is expressed by the resource-oriented patient-nurse partnership in the process of nursing, by team communication, as well as the heavily weighing discrepancy between knowledge and limited authorisation.

Effector-specific visual information influences kinesthesis and reaction time performance in Parkinson's disease.

Twelve patients diagnosed with idiopathic Parkinson's disease and 11 age-matched control participants performed a continuous bimanual wrist flexion-extension tracking task while vision of their hands was manipulated. Participants were required to match the frequency and amplitude of movements of 1 limb that was driven at 0.6 Hz by a torque motor by actively moving the contralateral limb. In half the trials, the more affected limb (subdominant for controls) was driven, and in the other half, the less affected limb (dominant for controls) was driven. Vision of both hands, vision of the driven hand only, vision of the active hand only, or no vision of the hands was allowed. Simple and probe reaction times were assessed. Parkinson's disease patients performed the tracking task to a reasonable level of temporal and spatial accuracy as compared with control participants in terms of hand phasing and root mean square error. Patients demonstrated a marked posture deviation (toward flexion), which was exaggerated when the less affected limb was active. Amplitude deviations were smaller in both groups when the less affected (dominant) limb was active and when participants had vision of the driven hand. Overall, patients delivered slower responses in both simple and probe conditions. Reaction times of Parkinson's disease patients who were allowed vision of only the active hand were longer than were those of patients in all other visual conditions, whereas visual conditions did not affect the reaction times of control participants. The authors conclude that central demands increase when movement regulation must be based solely on kinesthetic information and when vision directs attention away from the most relevant source of kinesthetic information.
