ClinConnect Summary

This clinical trial is studying how different control methods of wearable robotic devices can help people recovering from a stroke improve their walking. The trial focuses on training patients to walk with the help of a robot that supports the lower legs. Participants will complete walking sessions where they walk back and forth along a hospital corridor with the robot, using three different types of control settings to see which works best.

To take part, patients need to be between 18 and 75 years old, have had a stroke at least three months ago, and be able to stand and walk at least 10 meters on their own. They should have some movement in their legs but still experience difficulty walking. Participants must be medically stable, able to understand and follow instructions, and have no serious balance, coordination, or health problems that would make the training unsafe. During the trial, patients will complete several short walking trials with the robotic device, and their progress will be monitored. This study is currently recruiting participants who meet these criteria and are interested in trying this innovative approach to stroke rehabilitation.

Eligibility criteria

• Inclusion Criteria:
• • Stroke patients aged between 18 and 75 years. Patients who are medically stable and able to stand and walk independently for at least 10 meters during rehabilitation.
• • Stroke event occurred at least 3 months ago Patients with impaired lower limb motor function but with some degree of muscle activity in the lower extremities.
• • Patients without severe cognitive impairment and capable of understanding and following the treatment protocol.
• • Patients without severe balance or coordination disorders, able to maintain balance and perform gait training with assistive devices.
• • Patients without lower limb fractures or other serious skeletal issues affecting the lower limbs.
• • Patients without severe cardiovascular or other serious illnesses and able to tolerate the intensity and duration of rehabilitation therapy.
• • Patients willing to participate in the study and able to provide written informed consent.
• Exclusion Criteria:
• • Severe cognitive impairment that prevents the patient from understanding or complying with the treatment protocol.
• • Severe balance or coordination disorders that prevent the patient from maintaining balance and participating in gait training, even with assistive devices.
• • Other serious motor disorders, such as abnormal muscle tone or ataxia, which may interfere with the effectiveness of rehabilitation therapy.
• • Active cardiovascular disease or other serious systemic illnesses that may affect the patient's safety or treatment outcomes.
• • Lower limb fractures or other serious skeletal issues that may impact the suitability and safety of robot-assisted rehabilitation therapy.
• • Patients currently receiving other rehabilitation or experimental treatments. Patients with skin ulcers, infections, or other severe skin conditions that may interfere with the use and application of robotic devices.
• • Unexplained discomfort or pain symptoms that may limit the patient's ability to participate in rehabilitation therapy.
• • Failure to meet other specific inclusion criteria outlined in the study protocol.
