Filter by:This project seeks to evaluate the effect of transcranial alternating current stimulation (tACS) on the recovery of motor control of the upper limb and associated neuronal synchrony during a 14-sessions (5-week) rehabilitation program for adult patients with diagnosis of stroke at chronic stage. Specifically, the stimulation on Gamma ranges, because the evidence available so far allows us to propose that the tACS in the Gamma range (around 70 Hz) facilitates motor execution. For this purpose, the experimental approach involves active (70 Hz in Gamma rhythm and 7 Hz, Theta rhythm) and sham tACS together with an analytical and integrated motor training with a double-blind and randomized design. Our hypothesis is that Gamma frequency tACS restores neuronal synchrony in Beta range, which enhances the upper limb motor recovery associated with a training program. Using specific motor control parameters, clinical scales and electroencephalography, the immediate and long-term (3 months after finished the training) behavioral and neurophysiological effect of this new neurostimulation paradigm (tACS plus training) for motor rehabilitation of stroke will be established.
This study wants to know if using handheld dynamometry (HHD) to test leg strength in persons who have had a stroke, will reduce mistakes and give therapists better information to use for therapy. This study will collect normal values of leg muscle peak force production, cumulative peak force production, and sustained peak force production in patients with chronic stroke.
The purpose of this clinical research is to verify if the patients with chronic stroke can regain the ability of living independently after daily using Testa BioHealing® Biophoton Generators to increase the energy of the brain and other parts of the body. The main study questions are: - Can patients with chronic stroke regain life independence by normalizing Activities of Daily Living (ADL). - Can brain-injury and recovery status of the patients with chronic stroke be detected by using an EEG machine. Participants will sleep-rest on a hotel bed energized by Tesla BioHealing Biophoton Generators, and clinical study staff will observe the participant's activities of daily living, as compared to those who will sleep in the hotel room equipped with placebo devices.
The purpose of this cross-sectional study is to translate and cross-culturally adapt to Spanish the Motor Evaluation Scale for Upper Extremity in Stroke Patients (MESUPES) and the Stroke Upper Limb Capacity Scale (SULCS) and to assess their psychometric properties in Spanish people with chronic stroke.
This project will examine the feasibility, safety and effect of home-based functional electrical stimulation (FES) applied to different lower limb muscles in combination with task-specific training on gait, balance and mobility in adults with chronic stroke. 30 individuals with chronic stroke will first undergo initial screening and baseline walking, mobility, balance and strength assessments in the laboratory. After determining their eligibility for the study, they will undergo 12-weeks of home-based FES and task-specific training. Following the initial screening (week 1) and pre-intervention assessment (week 2), participants will be trained in the lab for 6 sessions (week 3-4) for a FES home program and then given a FES home kit (FES device and an android tablet). Participants will then undergo home-training for 2 weeks (week 5-6) followed by mid-training assessment (week 7). Again, participants will undergo 4-weeks of home training (week 8-11) and final assessment at the end of training (week 12). This project has the following specific aims: Aim 1: To investigate the feasibility, safety and efficacy of 12-weeks of home-based FES and task-specific training in adults with chronic stroke. Aim 2: To examine the effect of 12-weeks of home-based FES and task-specific training on mobility, gait and balance (anticipatory and reactive balance) in adults with chronic stroke.
This study will determine the acceptability of delivering seated exercises online and if seated exercises can improve balance, mobility, quality of life, and cardiometabolic health in those living with a stroke related mobility impairment. Participants will be allocated to either a 10-week seated exercise program or a delayed 2-week Boot Camp program. All seated exercises sessions and assessments will be conducted virtually.
The purpose of this study is to Investigate the feasibility of a high-quality, high-dose, high-intensity upper extremity therapy program and to assess the treatment effects of a high-quality, high-dose, high-intensity upper extremity therapy program on functional outcomes, motor impairment, and quality of life
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 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.
