Active clinical trials for "Paraplegia"

The study seeks to determine whether high intensity interval training has an effect on cardiovascular parameters in wheelchair users with paraplegia.

Hereditary spastic paraparesis type 11 (SPG11) is caused by mutations in the SPG11 gene that produces spatacsin, a protein involved in lysosomal function. Studies performed in skin cells (fibroblasts) from SPG11 patients, mice and zebrafish models of the disease showed that the material accumulated in the lysosomes is made of glycosphingolipids (GSL). Miglustat is a drug that inhibits an enzyme called glucosylceramide synthetase (GCS) which is used for the production of GSL. Miglustat, therefore, helps to delay the production of GSL. This study aims to collect preliminary data on the safety of miglustat on the SPG11 disease and to assess biomarkers.

Background: Hereditary spastic paraplegia (HSP) usually progresses slowly. Researchers want to learn more about how its symptoms change over time. They want to look for changes in the blood and cells of people with the most common forms of HSP that might allow them to better understand the disease. Objectives: To learn more about common forms of hereditary spastic paraplegia and find out how it progresses over time. Eligibility: People age 7 and older with SPG3A, SPG4A, or SPG31 Design: Participants will have 1 two-hour visit each year for up to 5 years. At 1 visit, adult participants may have a skin biopsy. An area of skin will be numbed then a tool will remove a small piece of skin. At all visits, all participants will have a physical exam and blood drawn. At all visits, participants will do a few tasks like walking quickly and climbing stairs. Participants can give permission for their skin cells, DNA samples, and data to be used in other studies. The samples and data will have no identifying information.

Incomplete spinal cord injury often results in difficulty walking. Training on a treadmill with body weight support may improve walking ability after spinal cord injury. The purpose of this study is to examine the effect of treadmill speed on spinal cord function and walking performance.

The purpose of this study is to compare transcutaneous electrical spinal stimulation (TESS) and epidural electrical stimulation (EES); in particular, the motor activity enabled by each method and the potential health benefits of each method.

The purpose of this research is to compare the effectiveness of a training protocol integrating Brain-machine Interfaces, Visuo-tactile feedback and Assisted Locomotion (referred to as the Walk Again Neurorehabilitation protocol, or WANR), with classical physiotherapy training for patients with chronic complete paraplegia due to spinal cord injury.

Ambulation would bring many physiological and psychological benefits and getting up and walking has been a dream for paraplegia patients.The reciprocating gait orthoses (RGOs) for paraplegics particularly draws research attentions because it mimics human gait pattern.But, the high energy consumption and low walking speeds caused the frequent abandonment or the low utilization of the reciprocating gait orthoses.To improve the design reducing the energy expenditure, it requires biomechanical analysis of the pathological gait such that the gait deviations and energy consuming mechanisms can be identified and remedial means can be implemented. The investigators hypotheses will include that there would exist an energy saving mechanism of human reciprocating locomotion based on the principle of conservation of mechanical energy.Secondly, kinematic and kinetic gait determinants could be derived from the energy saving mechanism. Finally, the control of knee joint coordinating with the hip joint movements would facilitate the gait progression and further reduce the energy consumption. The objective of this clinical trial is to evaluate the gait of paraplegic patients with reciprocating gait orthoses and to support the investigators research in biomechanical analysis, design and control of reciprocating gait orthoses for paraplegia patients. An experiment to study the pathological gait of paraplegia patients with an existing reciprocating gait orthosis will be carried out.

The primary objective of this study is to achieve successful walking skills using exoskeletal walking devices over the course of 36 sessions in 3 months at specific velocities and distances in people with chronic SCI who are wheelchair dependent for community mobility. The secondary objectives are to determine if this amount of exoskeletal walking is effective in improving bowel function and body composition in the same patient population. The exploratory objectives are to address additional questions concerning the retention or non-retention of the positive changes, the effects of the increased physical activity from this intervention on vagal tone, orthostatic tolerance, lipid profile, total testosterone, estradiol levels, and quality of life (QOL). A Phase III randomized clinical trial (RCT) will be performed using a crossover design and employing an exoskeletal-assisted walking intervention. The experimental arm will be compared to a usual activities (UA) arm, as the control, in 64 persons with chronic SCI (>6 month post injury) who are wheelchair-dependent for outdoor mobility in the community. The WALK arm will consist of supervised exoskeletal-assisted walking training, three sessions per week (4-6 h/week) for 36 sessions for their second 12-week period. The UA arm will consist of identification of usual activities for each participant, encouragement to continue with these activities and attention by study team members throughout the 12-week UA arm. These activities will be recorded in a weekly log. The investigators hypotheses are that 1) this exoskeletal intervention will be successful in training ambulatory skills in this patient population, 2) the exoskeletal intervention will be better than a control group in improving body composition, bowel function, metabolic parameters and quality of life in the same population.

Spinal cord injury (SCI), causes loss of supra-spinal control of the sympathetic nervous system and in some cases loss of sensation. As a result, people with SCI have impaired thermoregulatory system and the consequence of this thermoregulatory dysfunction, is that they cannot respond to the environmental changes. All the above lead to dysregulation in vasomotor tone, skeletal muscle shivering and sweating dysfunction. It is well known that skin plays an important role in regulating body temperature and regulates interactions between the environment and human body. A previous study in people with incomplete SCI showed that there are no differences in core temperature between patients with different level of mobility and sensation and different level of lesion, but there are significant differences in skin temperature. As mentioned above people with SCI have an impaired thermoregulatory capacity due to sudomotor and vasomotor dysfunction and that leads to greater thermal strain during rest and exercise when they expose to hot conditions. A previous study that performed exercise in people with SCI, highlights the fact that because of the impaired evaporative heat loss during exercise in hot conditions, they are in great risk. Because of this risk they propose different cooling strategies that promote evaporation such as fans and water spraying. It is therefore important to observe the thermoregulatory function (vasomotion and sudomotor) in people with SCI when they are exposed to different environments (cold, neutral and warm).

Spinal cord injury (SCI) is a devastating, life-altering injury; requiring tremendous changes in an individual's lifestyle. Cycling, provides an ideal way for individuals with SCI to exercise and address the long-term consequences of SCI by targeting the lower extremity muscles. Cycling with the addition of functional electrical stimulation (FES) allows persons with paralysis to exercise their paretic or paralysed leg muscles. The Queen Elizabeth National Spinal Injury Unit (QENSIU) in Glasgow offers FES cycling for people with spinal cord injuries, which combines functional electrical stimulation (FES) with a motorised ergometer that allows repetitive cycling activity. It stimulates muscles with electrodes attached to the skin, producing muscle contractions and patterned activity. So far no previous randomised control trials on FES cycling in the acute SCI population have reported changes in ability to undertake activities of daily living or the trunk balance.
