Filter by:In this study, it is aimed to examine the effect of rigid taping on hyperextension control in stroke patients with knee hyperextension in the stance phase of gait. Hypothesis Ho: Rigid taping has no effect on the control of knee hyperextension in stroke patients. H1: Rigid taping has an effect on the control of knee hyperextension in stroke patients.
Introduction: Gait speed is currently used to predict the future functional status of the patient or to evaluate the improvements produced by different neurorehabilitation treatments. There is no common agreement among researchers and clinicians as to the optimal distance required to accelerate and decelerate in walking tests (4-meter and 6-meter timed) in people in the chronic phase of stroke. Objectives: The main objective is to analyze what is the optimal distance to accelerate and decelerate in the 4-meter walk test (4mWT) and 6-meter walk test (6mWT) at comfortable and fast speed with optical motion capture for chronic stroke survivors (> 6 months). The secondary objective is to evaluate whether the mean gait speed taken by stopwatch is comparable to optical motion capture system Optitrack for the 4mWT and the 6mWT for a correct measurement of gait at comfortable and fast speed in in chronic stroke survivors. Methods: A cross-sectional observational study is performed. The walking speed is measured using the OptiTrack optical motion capture system consisting of 8 PrimeX 13 cameras and Motive 2.0 capture and analysis software (Natural Point Inc. Corvallis OR USA).The patient ware 8 markers sensors applied to different parts of the body. The two tests are performed first at a comfortable gait and second at the fastest gait that the patient can safely perform. There were 3 repetitions for each of the tests. The individuals are randomized to start with either the 6mWT or the 4mWT test. All tests are performed on the same day. Discussion: This study will shed light on what is the optimal distance required for acceleration and deceleration phases on the 6mWT and 4mWT walking tests at comfortable and fast speed.
The goal of this intervention study is to investigate the effects of immersive virtual reality in rehabilitation of language and communication of individuals with post-stroke aphasia. The main research questions are: 1. Is VR-based script training a feasible treatment to Cantonese-speaking PWA? 2. Will VR-based script training, when compared to conventional script training, better enhance treatment outcomes in functional communication of PWA? Participants will be assessed before, in the middle of, immediately after treatment and 8-week post treatment in terms of their performance on: 1. Accuracy and time for producing trained scripts. 2. Accuracy and time for producing un-trained scripts 3. Standardized aphasia test on severity of language impairment 4. Standardized aphasia test on functional communication The participants will be randomly allocated to receive one of the treatment: 1. Virtual reality-based computerized script training; or 2. Computerized script training without virtual reality Researchers will compare the treatment outcomes of the two treatment conditions and see if treatment with virtual reality would better promote outcomes when compared to training without virtual reality.
The purpose of the study is to compare assessments of arm function following a standard exercise program in chronic stroke patients.
Upper limb impairment is present in more than 85% of people with stroke, which greatly affect the quality of life, social participation, and performance of daily activities of people with stroke. Previous study also revealed that 53.4% of people after stroke experienced cognitive impairment. Different cognitive domains might be affected following stroke, such as attention, memory, language, and orientation, and the problems with memory are often prominent. Yet, there is no effective treatment for the post-stroke cognitive impairment. Transcutaneous electrical nerve stimulation (TENS) applied on thoracic region and transcutaneous vagus nerve stimulation (tVNS) are simple and non-invasive treatment to improve upper limb motor function and cognitive function. However, no existing studies have explored on the effects of TENS and tVNS on cognitive function in people with stroke. Therefore, the purpose of this study is to evaluate the effectiveness of TENS on improving upper limb function and cognitive function in people with chronic stroke. Also, this study will investigate the cortical response of people with stroke during TENS by using EEG power spectrum analysis.
The recovery from a stroke is often incomplete. It is the leading cause of acquired permanent disability in the adult population. Persistent functional loss of the hand and arm contributes significantly to disability. However, the current standard of care to treat hand and arm movements are inadequate. There is an urgent need for innovative and effective therapies for recovery of the upper limb after stroke. Growing evidence shows that electrical spinal cord stimulation, combined with activity-dependent rehabilitation, enables voluntary movement of paralyzed muscles in some neurologic disorders, such as spinal cord injury. The investigators hypothesize that spinal networks that lost control after stroke can be activated by non-invasive electrical stimulation of the spinal cord to improve functional recovery. The aims of the study are: 1. to determine the improvements in hand and arm function that result from the combined application of non-invasive spinal stimulation and activity-based rehabilitation. Surface electrodes placed over the skin of the neck will be used for non-invasive electrical stimulation of the spinal cord. Functional task practice will be used for activity-dependent rehabilitation, 2. to evaluate long-lasting benefits to hand and arm function that persist beyond the period of spinal stimulation.
After a stroke, 80% of patients continue to have difficulty using their paretic upper limb in activities of daily living (ADL) despite post-stroke rehabilitation practices that aim to promote the use of the paretic upper limb. It is known that functional recovery depends on actual use (Use it or Loose it), but one-time measurements in the clinic do not allow quantification of the actual use of the paretic upper limb in daily life (in the person's living environment). The investigators hypothesize the feasibility of quantifying functional use of the paretic upper limb by actimetry in clinical routine.
The aim of this randomized controlled is to assess the effect of kinesiotape technique upon wrist joint among the patients with chronic stroke. Patients are devided into groups, in group A kinesiotaping facilitation technique is applied on wrist extensor muscles while inhibition technique is applied on wrist flexor muscles and the result is the compared between the groups and within the group.
The purpose of our study is to evaluate Vibrotactile Coordinated Reset stimulation (vCR) and its effects on motor ability within stroke patients. vCR will be administered with a device called the Vibrotactile (VT) Brain Glove. vCR is expected to provide patients with a non-invasive therapy to aid in recovery from a stroke. This study will include a dedicated sham arm that will aid in understanding true treatment effects from vCR.
