Efficacy and Safety of 6Degrees MyMove Interactive Virtual Reality Compared to Passive Virtual Reality in Subacute Stroke and Traumatic Brain Injury Rehabilitation: A Randomized Controlled Trial

Stroke and traumatic brain injury frequently result in persistent upper and lower limb motor impairment. While conventional rehabilitation improves outcomes, patient adherence and training intensity remain limiting factors. Immersive virtual reality (VR)-based therapy may enhance neuroplasticity by delivering high-intensity, task-oriented motor practice with enriched sensory feedback. This randomized controlled trial evaluates the efficacy and safety of the 6Degrees MyMove interactive VR system compared to passive VR exposure in individuals undergoing subacute inpatient rehabilitation after stroke or traumatic brain injury. Sixty participants will be randomized 1:1 to receive either interactive VR-based motor training or passive VR viewing, in addition to standard rehabilitation care, three times weekly for eight weeks. The primary objective is to determine whether interactive VR leads to greater improvement in motor function compared to passive VR. Secondary outcomes include dexterity, gait speed, functional independence, psychological status, adherence, usability, and safety.

Intravenous Thrombolytic Therapy in Acute Ischemic Stroke Patients on DOAC

Direct oral anticoagulants (DOAC) have emerged as safe and efficacious ischemic stroke prophylaxis for non-valvular atrial fibrillation (NVAF). All four DOACs - apixaban, dabigatran, edoxaban, rivaroxaban - were associated with lower risks of major bleeding compared to warfarin. Listed as core essential medicines by the World Health Organization, DOAC prescriptions have been surging worldwide. In Hong Kong, approximately 80,000 patients received DOACs from January 2009 through December 2022 according to the Hospital Authority registry. The widespread DOAC usage had created DOAC-specific clinical dilemmas that lack evidence-based treatment despite twenty years of prescribing experience. Ischemic stroke despite DOAC (IS-DOAC), in particular, may occur in up to 6% of DOAC users annually. Due to the in vivo anticoagulation effect, there had been concerns of intracerebral bleeding (ICH) with intravenous thrombolytic therapy (IVT) for acute IS-DOAC. Under the current guideline recommendations, most acute IS-DOAC are contraindicated to IVT (see Intravenous thrombolytic therapy), which resulted in only a small proportion of acute ISDOAC patients being able to receive IVT even if presented early. Nonetheless, our group found that majority of patients had a DOAC level of \<50ng/mL only 24 hours after DOAC cessation (see work done by us), a level deemed clinically negligible and safe for thrombolytic therapy. Together with evolving clinical evidence discussed below, IS-DOAC patients maybe unnecessarily barred from IVT, thus compromised functional recovery. With robust pharmacokinetic and retrospective clinical evidence to support, it is hypothesized that IVT are safe in IS-DOAC patient. The investigators hereby propose a prospective multicenter study to determine the efficacy and safety of IVT in acute IS-DOAC.

Constraint-Induced Movement Therapy for Adults Post-Stroke With Mild Upper Extremity Impairment

Constraint-Induced Therapy (CI Therapy) is a behavioral approach to neurorehabilitation and consists of multi-components that have been applied in a systematic method to improve the use of the limb or function addressed in the intensive treatment. CI Therapy for the more-affected upper extremity (UE) post-stroke is administered in daily treatment sessions over consecutive weekdays. Sessions include motor training with repeated, timed trials using a technique called shaping, a set of behavioral strategies known as the Transfer Package (TP) to improve the use of the more-affected hand in the life situation, and strategies to remind participants to use the more-affected UE including restraint. Robust improvements in the amount and qualify of use have been realized with stroke participants from mild-to-severe UE impairment.

A Novel, Comprehensive Approach to Post-stroke Gait Rehabilitation

The goal of this project is to determine the feasibility and optimal parameters of a novel, comprehensive approach to gait training in individuals with chronic stroke. The comprehensive approach includes biofeedback-based gait training and aerobic exercise intensity-based gait training.

Cognition and Motor Learning Post-stroke

This project seeks to determine how post-stroke cognitive impairment moderates motor learning during walking in older adults with chronic stroke and identify brain structural markers that mediate this relationship. The chosen experimental design integrates biomechanical analyses, neuropsychological assessments, and brain imaging techniques to determine the impact of post-stroke cognitive impairment severity on two forms of motor learning (explicit and implicit) and examine the role of the dorsolateral prefrontal cortex in the relationship between cognition and explicit motor learning. Ultimately, this work may lead to the development of a more comprehensive, effective treatment approach to improve walking dysfunction in older adults post-stroke.

Constraint-Induced Movement Therapy Plus Sensory Components After Stroke

Constraint-Induced Movement Therapy or CI Therapy is a form of treatment that systematically employs the application of selected behavioral techniques delivered in intensive treatment over consecutive day with the following strategies utilized: behavioral strategies are implemented to improve the use of the more- affected limb in life situation called a Transfer Package (TP), motor training using a technique called shaping to make progress in successive approximations, repetitive, task oriented training, and strategies to encourage or constrain participants to use the more-affected extremity including restraint of the less-affected arm in the upper extremity (UE) protocol. Numerous studies examining the application of CI therapy with UE rehabilitation after stroke have demonstrated strong evidence for improving the amount of use and the quality of the more-affected UE functional use in the participant's daily life situation. CI Therapy studies with adults, to date, have explored intensive treatment for participants with a range from mild-to-severe motor impairment following stroke with noted motor deficits and limited use of the more-affected arm and hand in everyday activities. Each CI Therapy protocol was designed for the level of impairment demonstrated by participants recruited for the study. However, often following stroke, patients not only have motor deficits but somatosensory impairments as well. The somatosensory issues have not, as yet, been systematically measured and trained in CI Therapy protocols with adults and represent an understudied area of stroke recovery. We hypothesize that participants with mild-to-severe motor impairment and UE functional use deficits can benefit from CI therapy protocols that include somatosensory measurement and training components substituted for portions of motor training without loss in outcome measure gains. Further, we hypothesize that adults can improve somatosensory outcomes as a result of a combined CI therapy plus somatosensory component protocol.

A randomized control trial will be done on diagnosed stroke patients of subacute stage in Fauji Foundation Hospital Rawalpindi and leading edge physical therapy and rehabilitation clinic.The purpose of the study is to determine Additional Effects of Kinesio-Taping along with conservative Physical Therapy on upper limb function, Range of motion and Spasticity in the patients with Subacute Stroke. The conservational physical therapy includes Passive and active ROMs 25 repetitions each, 3 times per week. PNF stretching (hold relax) for spastic muscles for 20 repetitions with a 10 second hold and 10 second relaxation of the muscle group 3 times per week. D1 flexion and extension for 20 repetitions 3 times per week. Kinesio tape 3 times per week.

The Brain Injury Neurorehabilitation Project

The primary objective of The Brain Injury Neurorehabilitation Project is a systematic effort to generate cutting edge research in brain injury and cognitive rehabilitation that will advance neurorehabilitation research. It will establish the first surveillance system and implement multimodal data to characterize the long-term effects of moderate to severe TBI. Additionally, the project will implement innovative rehabilitation methodologies, namely, cognitive training, social communication deficits and non-invasive brain stimulation with tDCS, to determine which modality can improve neurocognitive and psychosocial performance in adult ABI. Two funded projects, BRAIN-REHAB \& ACESO are incorporated in this project.
