Understanding gait adaptation is essential for rehabilitation, and visual feedback can be used during gait rehabilitation to develop effective gait training. We have previously shown that subjects can adapt spatial aspects of walking to an implicitly imposed distortion of visual feedback of step length. To further investigate the storage benefit of an implicit process engaged in visual feedback distortion, we compared the robustness of aftereffects acquired by visual feedback distortion, versus split-belt treadmill walking. For the visual distortion trial, we implicitly distorted the visual representation of subjects’ gait symmetry, whereas for the split-belt trial, the speed ratio of the two belts was gradually adjusted without visual feedback. After adaptation, the visual feedback or the split-belt perturbation was removed while subjects continued walking, and aftereffects of preserved asymmetric pattern were assessed. We found that subjects trained with visual distortion trial retained aftereffects longest. In response to the larger speed ratio of split-belt walking, the subjects showed an increase in the size of aftereffects compared to the smaller speed ratio, but it steeply decreased over time in all the speed ratios tested. In contrast, the visual distortion group showed much slower decreasing rate of aftereffects, which was evidence of longer storage of an adapted gait pattern. Visual distortion adaptation may involve the interaction and integration of the change in motor strategy and implicit process in sensorimotor adaptation. Although it should be clarified more clearly through further studies, the findings of this study suggest that gait control employs distinct adaptive processes during the visual distortion and split-belt walking and also the level of reliance of an implicit process may be greater in the visual distortion adaptation than the split-belt walking adaptation. 相似文献
People of color with borderline personality disorder (PoCwBPD), in particular African-Americans and Latinxs in the inner city, present a special population at risk for unemployment and long-term impairment in psychiatric and psychosocial recovery. A growing literature points to the need for comprehensive care that addresses the symptoms of the borderline syndrome alongside social, vocational, and educational achievement. This article paints a picture of the individual, communal, and systemic complexities involved in aiding PoCwBPD achieve psychosocial recovery. After contextualizing the historical and systemic forces that impact recovery for PoCwBPD, I discuss principles of intervention to assist clinicians tailor treatment to this population. Drawing on insights from Transference-Focused Psychotherapy, an evidence-based psychodynamic therapy for BPD, I offer a theoretical cultural adaptation for people of color. This article provides clinical vignettes to illustrate the resulting model, and shows that helping the patient engage in productive activity provides the foundation for exploratory work, which in turn addresses intrapsychic obstacles to psychosocial success. 相似文献
The authors aimed to investigate the effects of an intervention based on interactive game set with the movement sensor Kinect on children with cerebral palsy (CP). Twenty-eight participants were recruited. Their age was between 3 and 12 years old, and rated as level I, II, or III on the Gross Motor Function Classification System. They played two games from the Xbox 360 Kinect system and were evaluated using the Gross Motor Function Measure (GMFM) after a period of 8 weeks. The intervention led to significant motor function improvement as increase of the global scores on the GMFM (p < .001). Rehabilitation interventions using the Xbox 360 Kinect interactive games may represent useful tools for children with CP. 相似文献
This study was conducted to investigate the effects of speed-interactive treadmill training (SITT) using smartphone-based motion tracking technology on gait in stroke patients. Thirty-four chronic stroke patients were randomly divided into a SITT group (n = 18) and a standard treadmill training (control) group (n = 16). The SITT group underwent smartphone-based SSIT while the control group underwent standard treadmill training. Both groups performed the training for 35 min per session, 3 times per week, for 6 weeks. Both groups used nonmotorized treadmills so that patients could control the speed. Evaluation was conducted during the week before and after the training. The OptoGait system measured gait spatiotemporal parameters. Both groups showed significant improvement in the temporal and spatial gait parameters (p < .05). In the SITT group, compared to the control group, the two-way analysis of variance with repeated measures showed an improvement in the temporal and spatial gait parameters after the intervention period (p < .05). This study confirmed that SITT improved the gait function of stroke patients. Based on this result, the authors propose that SITT, by improving gait, can be used as an effective training method to improve patients' functional activities in the clinic. 相似文献
There is converging evidence that changing beliefs about an illness leads to positive recovery outcomes. However, cardiac misconceptions interventions have been investigated mainly in Angina or Coronary Heart Disease patients, and less in patients following Myocardial Infarction (MI). In these patients, cardiac misconceptions may play a role in the adjustment or lifestyle changes. This article reports a randomized controlled trial of an intervention designed to reduce the strength of misconceptions in patients after a first MI. The primary outcome was the degree of change in misconceptions and the secondary outcomes were: exercise, smoking status, return to work and mood (anxiety and depression). Patients in the intervention condition (n = 60) were compared with a control group (n = 67) receiving usual care. Both groups were evaluated at baseline and 4, 8 and 12 months after hospital discharge. There was a significant time-by-group interaction for the total score of cardiac misconceptions. Patients in the intervention group significantly decreased their total score of cardiac misconceptions at 4 months compared with the control group and this difference was sustained over time. Patients in the intervention group were also more likely to exercise at the follow-up period after MI than the control group. This intervention was effective in reducing the strength of cardiac misconceptions in MI patients and had a positive impact on health behaviour outcomes. These results support the importance of misconceptions in health behaviours and the utility of belief change interventions in promoting health in patients with Myocardial Infarction. 相似文献
Cognitive training can allow patients with Alzheimer’s disease (AD) to reinforce individual cognitive abilities. In the present case study, we investigated the generalizability of trained cognitive skills to novel tasks, and their stability over time.
One AD patient underwent a structured cognitive training using the GEO (Geographical Exercise for cognitive Optimization) task, whereas eight AD patients underwent a control cognitive intervention. Participants’ performances on the GEO task, on a similar untrained cognitive task, and on a different untrained cognitive task were recorded before and after the intervention, and at the follow-up. On both the trained and the similar untrained tasks patients’ and controls’ performance significantly differed from one another. Our preliminary evidence shows that a cognitive training could allow patients to improve and maintain their performance not only on the trained task, but also on a similar task. 相似文献
This article explores a female university volleyball student-athlete’s experience with protracted concussion symptoms. Through the methodology of narrative inquiry, four salient themes became apparent related to Daphnée’s experiences: (a) “I felt so alone,” (b) “I had to make one of the hardest decisions of my life,” (c) “I feel like I’m in prison,” and (d) “There’s no light at the end of the tunnel.” Overall, this study offers a rare look into the impact of concussion on an individual’s athletic and academic identities, career progression, and in turn, her imagined stories of who she was and who she was becoming. 相似文献
Changes in health care have dramatically curtailed services to people with severe physical disability and their families. This has placed a greater burden of responsibility on those who live with these conditions and have ongoing care needs. Yet little is known about the subjective problems, challenges, and solutions reported by these people. We demonstrate how the nominal group technique can be used to obtain consumer-oriented information germane to these individuals and their concerns. We conducted nominal group technique meetings with 2 groups for persons with physical disability and a third with a group for family members in caregiving roles. We demonstrate how focus groups can be conducted with the nominal group technique to identify problems experienced by individuals who live with severe physical disability. Recommendations for using the nominal group technique with client populations are presented, and implications for clinical practice are discussed. 相似文献
