Clinical trials

Patients with vascular and metabolic transfemoral amputations experience substantial functional limitations and high rates of prosthetic abandonment. Although multidisciplinary inpatient rehabilitation programs have been associated with improved outcomes, evidence regarding their effectiveness in low- and middle-income countries remains limited. This study aims to evaluate the effectiveness of an inpatient rehabilitation and prosthetic training model implemented at the National Institute of Rehabilitation "Luis Guillermo Ibarra Ibarra" (INRLGII), Mexico. An ambispective cohort design will be used, including a retrospective review of patients treated between 2013 and 2025 and a prospective cohort enrolled between 2026 and 2029. The primary objective is to determine the proportion of patients who achieve functional prosthesis use after hospital discharge. Secondary objectives include identifying clinical, metabolic, functional, and psychosocial factors associated with successful prosthetic use, adherence, and abandonment.

The study's main goal is to determine the efficacy of a therapy with brain-computer interface controlled functional electrical stimulation for neurorehabilitation of spinal cord injury patients' upper limbs. For this purpose, a randomized controlled trial will be performed to compare the clinical and physiological effects of the brain-computer interface therapy with those of a sham intervention comprised by the application of functional electrical stimulation independently of brain-computer interface control.

At the moment, the number of people with long COVID is unkown because there is still no effective diagnosis. This is why is very important to analyze the most common symptoms, which are: depression, anxiety and fatigue. This project seeks to analyze some blood components of people with long COVID, such as microRNAs and vitamin B12, in order to identify the body processes that changed after COVID-19 and thereby design better therapies and diagnostic methods focused on each of them. The hypothesis is that the expression of miR-21, -146a and -155 will be overexpressed as well as there will be a deficiency of vitamin B12 in serum in subjects suffering from long COVID with neurological symptoms of depression, anxiety and fatigue.

The objective of this research is to evaluate the efficacy of an experimental therapy for motor recovery of the arm after a stroke, which includes the application of a functional electrical stimulation therapy coupled to P-300 based Brain-Computer Interface system (BCI-FES). For this purpose, the investigators will compare two groups, the first one will receive only conventional physical therapy, while the second one will receive physical conventional therapy together with BCI-FES therapy. The control and experimental group will receive 20 sessions of conventional physical therapy at a rate of five sessions per week for 4 weeks, and the experimental group will receive 20 sessions of rehabilitation with the BCI-FES system at a rate of five sessions per week for 4 weeks. Broadly speaking, the BCI is in charge of determining the movement selected by the individual and assist the hand movement while performing functional tasks. The movements included in the sessions will be hand opening, grasping, pinching, pronation and supination, which are combined to facilitate the execution of functional movements that are performed together with the manipulation of daily used utensils. The visual, sensory and motor feedback provided by the BCI-FES system that enables the individual to replicate the afferent-efferent motor circuit, contributes to the activation and recruitment of neural pathways, which is associated with motor recovery. It should be noted that this BCI-FES system has already been tested previously in a study with healthy individuals, and in a non-randomized pilot study that used this therapy for upper limb motor function recovery in chronic post-stroke patients. It showed positive results, and the therapy was safe and tolerated by all the patients. Besides no adverse event related to the intervention occurred. To evaluate the results, a series of tests will be applied to assess the motor recovery and level of independence, including the FMA-UE: Fugl-Meyer Assessment Scale of Upper Extremity, ARAT: Action Research Arm Test, MAS: Modified Ashworth Scale, FIM: Functional Independence Measure and MAL: Motor Activity Log. Moreover, to assess neuroplasticity, two neuroimaging techniques including magnetic resonance imaging and electroencephalography will be used.
