Stroke With Hemiparesis

In post-stroke rehabilitation of the affected upper limb, increasing treatment intensity has been shown to lead to better outcomes compared to conventional approaches with fewer hours of therapy per day and week. However, logistical, human, and material constraints in neurorehabilitation centres often limit the feasibility of increasing treatment intensity. The GRASP programme (Graded Repetitive Arm Supplementary Program) is a home-based exercise intervention grounded in motor learning principles and conducted weekly under the supervision of an occupational therapist. This strategy enables the intensity of upper limb rehabilitation to be increased by up to seven additional hours per week. This project aims to evaluate the effectiveness of the Spanish version of the HomeGRASP programme, implemented as an adjunct to conventional occupational therapy, in improving quality of life, autonomy, and upper limb functionality in people after stroke. To this end, a single-blind, randomised controlled clinical trial will be conducted. Participants in the experimental group will receive conventional occupational therapy in addition to the HomeGRASP programme performed at home, while those in the control group will receive only conventional therapy. The treatment period for both groups will last eight weeks. Participants will be assessed at baseline and after the 8-week intervention period by a blinded evaluator. The primary outcomes will include changes in quality of life and upper limb functionality, measured using the CAVIDACE scale and the Wolf Motor Function Test. Secondary outcomes will include upper limb dexterity and personal autonomy, assessed using the Box and Block Test, Purdue Pegboard Test, Motor Activity Log-30, Duruöz Hand Index, and the Functional Independence Measure (FIM).

The aim of the study was to explore potential pathways for recovery and adaptation of the motor cortex by examining cerebral blood flow characteristics and hemodynamic markers analyzed by functional near-infrared spectroscopy (fNIRS) in patients with hemiparesis after stroke. Participants in the study performed a simple stimulus-response task several times with one healthy and one paralyzed limb at different stages of basic rehabilitation. A group of healthy, age-matched volunteers participated in the same experiment to verify the stroke-related changes. The researchers recorded fNIRS signals, muscle activity using electromyography, and heart activity using electrocardiography.

This clinical trial aims to investigate the effectiveness of a novel neurorehabilitation technology for treating stroke in adults. The study will evaluate a simulator that combines robotic orthosis, a non-invasive brain-computer interface (BCI), and a virtual reality (VR) display. The goal of this trial is to advance stroke rehabilitation by exploring the potential benefits of these cutting-edge technologies. Key Research Questions: Efficacy: Does the new simulator significantly improve arm function compared to standard rehabilitation techniques? BCI Technology: Which approach - motor imagery of only the paretic arm or both the paretic and healthy arm - yields greater functional improvements? VR Contribution: How does the integration of VR enhance rehabilitation outcomes? Safety and Tolerability: What potential side effects or adverse events may arise from using the new simulator? Participants who have suffered a stroke will undergo a standard rehabilitation course, during which 10-12 sessions will take place using the innovative simulator: a robotic device moves a patient's paralyzed arm at the command of a non-invasive brain-computer interface to perform a game task resembling real-life activities, augmented by a virtual reality display. Researchers will assess the impact of the new technology on arm function to determine its efficacy in promoting recovery.

The overarching goal is to determine if the BOOST GAIT program can improve functional mobility in patients with stroke who are undergoing inpatient rehabilitation and have some walking function, through the application of augmented therapeutic exercises designed to achieve a normative gait pattern. The evaluation will be conducted using a combination of clinical scales and objective motion sensors that map walking quality and performance during activities of daily living, such as rising from a chair and standing. It is acknowledged that this single-group pilot study, which aims to include 12 participants, is insufficiently powered to address the primary objective. A larger parallel-design study is required to definitively address this issue. To help design a larger study, the current objectives are: first, to have realistic expectations regarding recruitment and dropout rates; second, to identify potential barriers to therapy adherence and data collection that may impede the success of a larger study; third, assess the test-retest reliability of sensor-based motion capture of movement quality during walking and related tasks in hemiparetic stroke patients. For the latter objective, the sensor measurements at the end of the intervention will be repeated on two consecutive days. In addition to their usual care, participants will undergo additional therapy over a four-week period, with sessions occurring five times per week for one hour as part of the BOOST GAIT program. The BOOST GAIT sessions will be conducted as group-based therapy with four patients and two physiotherapists present to oversee the performance of mobility-specific exercises, including sit-to-stand transfers, standing and stepping, and eventually walking. The rationale for this approach is that the combined effects of augmenting the amount of therapeutic exercises and specifically targeting motor control of the paretic leg will facilitate symmetry during tasks, which in turn will have carry-over effects on safe performance of walking and other mobility tasks.
