Abstract: 

Study tested the reliability and validity of tracker-based posturography with a commercial virtual reality system to record the trunk displacement (TD) path for evaluation of sitting stability among stroke patients. Twenty-one stroke individuals and 21 healthy adults had their postural sway measured with this system under four sitting conditions, i.e., sitting on a solid surface or a soft surface, with eyes open or closed. The test-retest reliability of the TD parameters was evaluated with intraclass correlation coefficients in 22 participants. We also tested the discriminative validity of these parameters to discriminate between stroke and healthy controls, and among four sitting conditions. Furthermore, the TD parameters were correlated with the three balance function tests: the Berg Balance Scale (BBS), the Postural Assessment Scale for Stroke Patients (PASS) and the Function in Sitting Test. The results indicated that the TD parameters obtained by tracker-based posturography had mostly moderate to good reliability across the four conditions, with a few exceptions in the solid surface and eyes open tasks. The TD parameters could discriminate the postural stability between sitting on solid and soft surfaces. The stroke group had more seated postural sway than the control group, especially while sitting on a soft surface. In addition, velocity measures in the sagittal and frontal planes had moderate-to-high correlations with the PASS and BBS scores. This tracker-based system is a cost-effective option for the clinical assessment of body stability for stroke patients in a seated position and shows acceptable reliability and validity.

Abstract: Study compared the effects of dynamic neuromuscular stabilization (DNS) and conventional neurodevelopmental treatment (NDT) exercises on diaphragm movement, abdominal muscle thickness, and postural control in stroke patients. Thirty-one participants were randomly allocated into DNS and NDT for 30 minutes each day, 3 days a week for 4 weeks. Diaphragm movement and abdominal muscle thickness were determined using ultrasonography. The Trunk Impairment Scale and Berg Balance Scale (BBS) were used to measure postural control. The Functional Ambulation Category (FAC) was used to evaluate gait ability. Analysis of covariance (ANCOVA) was used to evaluate post-test differences in the DNS and NDT exercise groups. ANCOVA revealed the superior effects of DNS in diaphragm movement and abdominal muscle thickness (transversus abdominis, internal oblique), as well as clinical BBS and FAC tests, compared with those of NDT. The findings demonstrate that DNS training was more effective than NDT training in improving postural movement control and gait ability via a balanced co-activation of the diaphragm and transversus abdominis/internal oblique muscles in patients with hemiparetic stroke.

Abstract

Current methods of balance assessment in the clinical environment are often subjective, time-consuming and lack clinical relevance for non-ambulatory older adults. The objective of this study was to develop a novel method of balance assessment that utilizes data collected using the Microsoft Kinect 2 to create a Berg Balance Scale score, which is completely determined by statistical methods rather than by human evaluators. 74 older adults, both healthy and balance impaired, were recruited for this trial. All participants completed the Berg Balance Scale (BBS) which was scored independently by trained physical therapists. Participants then completed the items of the "Modified Berg Balance Scale" in front of the Microsoft Kinect camera. Kinematic data collected during this measurement was used to train a feed-forward neural network that was used to assign a Berg Balance Scale score. The neural network model estimated the clinician-assigned BBS score to within a median of 0.93 points for the participants in our sample population (range: 0.02-5.69). Using low-cost depth sensing camera technology and a clinical protocol that takes less than 5 min to complete in both ambulatory and non-ambulatory older adults, the method outlined in this manuscript can accurately predict a participant's BBS score and thereby identify whether they are deemed a high fall risk or not. If implemented correctly, this could enable fall prevention services to be deployed in a timely fashion using low-cost, accessible technology, resulting in improved safety of older adults.

Summary

Background

Stroke is one of the main causes of disability among adults.

Objective

The aim of the present study was to analyze the effect of postural insoles on static balance in individuals with stroke.
Methods: twenty-four strokes survivors with hemiparesis were recruited from the rehabilitation clinics of the university and randomly allocated to two groups: experimental and control group. The subjects were analyzed for stabilometry, immediately following insole placement and after three months of insole usage, with eyes open and eyes closed.

Results

A significant difference was found immediately after postural insole placement regarding anteroposterior range of movement (p < 0.05). Moreover, significant reductions were found in the inter-group analysis after three months of insole usage.

Conclusion

Based on the present findings, postural insoles combined with conventional physical therapy offer significant benefits regarding static postural control among stroke victims after three months of use, as demonstrated by computerized stabilometry.

Abstract

OBJECTIVE:

To evaluate the effect of caffeine on balance control of hemiparetic stroke patients, we investigated the difference in postural stability before and after drinking coffee by observing changes in stability index (SI) from posturography.

METHODS:

Thirty patients with history of stroke and 15 age-matched healthy subjects participated in this study. Effect of group factor (of the control and stroke groups) and treatment factor (pre- and post-drinking of coffee) on SI were tested in three conditions: with eyes opened, with eyes closed, and with a pillow support. The effects of these factors on visual deprivation and somatosensory change of subjects were also tested.

RESULTS:

Under all conditions, SI was higher in the stroke group than in the control group. Under eyes-open condition, the treatment factor was not statistically significant. Under eyes-closed condition, the interaction between group and treatment factor was statistically significant. After the subjects drank coffee, SI in the control group was increased. However, SI in the stroke group was decreased. Under pillow-supported condition, the interaction between group and treatment factor appeared marginally significant. For visual deprivation effect, the interaction between treatment and group factor was statistically significant. After caffeine consumption, the visual deprivation effect was increased in control group but decreased in the stroke group. For somatosensory change effect, the interaction between group and treatment factor was not statistically significant.

CONCLUSION:

Postural stability of hemiparetic stroke patients related to somatosensory information was improved after intake of usual dose of caffeine.

Documenting abnormal anticipatory control prior to gait initiation in sub-acute stroke

Background: Anticipatory postural adjustments (APAs) are medio-lateral centre of pressure (ML COP) shifts towards the swing limb to preserve lateral stability prior to gait initiation. Previous research demonstrated that APAs are reduced in magnitude or delayed among individuals with stroke compared to healthy controls.
Clinically, we have observed multiple APAs prior to gait initiation in individuals post-stroke, which has not been reported in the literature. The purpose of this study was to document the prevalence of abnormal APA patterns and to examine the differences in APA timing and magnitude in a sub-acute stroke population prior to gait initiation. Methods: Sixty-six independently ambulatory stroke inpatients stood on two force plates and were instructed to initiate gait at a self-selected speed. Six trials were completed, three leading with each limb. MLCOP was obtained from the force plates. An APA was defined as a shift in ML COP >10mm from baseline. An
abnormal APA pattern could involve either no APA or multiple APAs (mAPA). Results: Fifty-six percent of patients (37/66) exhibited trials with both one and multiple APAs. Foot-off time was significantly faster for trials with
mAPAs than those with one APA (p=0.0029). Unloading time for trials with mAPAs was also faster than those with one APA (p=0.014). Forty-eight percent of patients (32/66) demonstrated trials with both normal APAs and no
APA activity. When comparing trials with one APA to those with no APA, there were no significant differences in timing. Conclusions: This study reports a high prevalence of abnormal anticipatory control prior to gait initiation
in individuals with stroke. Significant temporal differences associated with multiple APAs exist, which alter the normal gait initiation sequence. The clinical significance of these abnormal APA patterns in individuals with stroke prior to voluntary gait initiation warrants further investigation.
