Clinical trials

To determine whether the combination of non-invasive spinal cord stimulation together with gait rehabilitation reduces spasticity and facilitates recovery of lower limb motor strength and gait function in patients with incomplete SCI, as well as studying the underlying physiopathological changes following incomplete SCI and its modulation by non-invasive stimulation techniques.

This clinical trial primarily aims to evaluate the safety and feasibility of a combined therapeutic approach for chronic spinal cord injury (SCI). The study will investigate whether the combination of intrathecal Wharton's jelly mesenchymal stem cells and transcutaneous spinal cord stimulation (tSCS) is safe and viable in individuals with chronic traumatic SCI. The trial will enrol 10 participants aged 16-70 with traumatic SCI (cervical or thoracic levels C1-T12) classified as ASIA Impairment Scale A-C, who are 1-5 years post-injury. Participants will receive three intrathecal injections of Wharton's jelly mesenchymal stem cells, each containing 30 million viable cells (±30%), administered intrathecally at the L3-L4 level. This cellular therapy will be combined with transcutaneous spinal cord stimulation and intensive neurorehabilitation. Participants will undergo comprehensive assessments over a 12-month follow-up period to monitor safety, feasibility, and secondarily to evaluate potential improvements in motor, sensory, and autonomic functions. Additional annual follow-up will continue for 2 years after study completion to evaluate long-term safety.

Acquired brain damage generates motor, cognitive, behavioral and emotional deficits. Neurorehabilitation aims to reduce these deficits and develop compensatory strategies that increase the person's functionality. However, the success of neurorehabilitation process varies and is influenced by the type of injury, the characteristics of the patient or the treatment received. Despite all the studies about patient characteristics, psychological aspects currently continue to be a field to be explored. The main objective of the study is to study the psychological characteristics of people with brain damage. Secondary objectives include analyzing its link with other indicators, exploring possible differences depending on the etiology of brain damage, assessing its evolution during neurorehabilitation and exploring its prognostic value. To carry out this prospective longitudinal observational study, adult patients with acquired brain damage to less than 6 months of evolution who present an objective cognitive alteration will be selected. Patients with a neurological or psychiatric history will be excluded. Patients included in the study will be administered computerized questionnaires at the beginning of the neurorehabilitation program. The same questionnaires will be administered again 2 months later. In those hospitalized patients who subsequently continue outpatient treatment, a third administration will be performed (2 months after the second administration).

The goal of this observational study is to develop a machine learning model to predict the outcome of a transcranial direct current stimulation (tDCS) treatment in patients suffering from neuropathic pain derived from a spinal cord injury. The main question it aims to answer is: • Can electroencephalography (EEG) and clinical assessment data predict the success of tDCS treatment in neuropathic pain patients? Participants will: * Undergo EEG recording sessions to collect brain activity data before treatment. * Complete clinical assessments, including medical diagnostics and questionnaires focused on factors related to neuropathic pain before and after treatment.
