Breakthrough in Spinal Injury Recovery: Paraplegic Patient Walks Again with Innovative Therapy
In a remarkable medical breakthrough, a 33-year-old man who became paraplegic due to a traumatic spinal injury has regained the ability to walk with the assistance of a walker and an orthotic device. This groundbreaking case, detailed in a study published by Cell Med and led by Italian scientists, marks the first documented recovery of walking through epidural electrical stimulation for a patient with such an injury.
Four years prior, the patient suffered a spinal injury at the T11 and T12 vertebrae levels, affecting the conus medullaris—the terminal part of the spinal cord—resulting in severe motor deficits from damage to both the central and peripheral nervous systems. The research team, based at San Rafael Hospital in Milan, implanted a spinal neurostimulator within the epidural space, applying specific stimulation and rehabilitation protocols that significantly enhanced the patient's muscle strength, walking capacity, and motor control.
Upon discharge after treatment, the patient could walk 58 meters in six minutes and complete a 10-meter test in just over 40 seconds. Remarkably, six months later, he was able to walk one kilometer using only a walker and leg braces—an achievement the team described as the most incredible milestone.
Dr. Luigi Albano, a neurosurgeon at San Rafael Hospital and the first author of the study, emphasized the potential of epidural electrical stimulation combined with rehabilitation to restore motor functions in patients with paraplegia, allowing them to achieve upright positions and walk shorter distances.
The stimulation not only facilitated motor recovery but also led to clinically significant improvements in the patient’s neuropathic pain and overall quality of life, adding to the compelling nature of this case according to another researcher, Dr. Pietro Mortini.
The findings of this study offer new hope for patients with severe spinal injuries who have experienced prolonged immobility, providing a pathway to recoveries previously thought impossible. Trauma to the conus medullaris is often caused by traffic accidents, falls, or violent events, representing over 50% of injuries at the junction between the spinal cord and spinal roots. Since these areas are complex to treat, patients typically have limited options, with many experiencing severe and persistent motor and sensory deficits impacting their quality of life and autonomy.
In this instance, the research team implanted a spinal stimulation system with 32 electrodes between the T11 and L1 vertebrae, effectively reactivating certain residual nerve circuits essential for regaining posture and walking abilities. Following this, the patient underwent an innovative rehabilitation program incorporating virtual reality exercises that integrated sensory and motor feedback.
Within three months, the patient exhibited substantial improvement in lower limb mobility and trunk postural control while seated. This entire journey to walking one kilometer underscores the importance of collaborative efforts among physiotherapists, rehabilitation physicians, neurologists, neurosurgeons, and engineers. As noted by co-author Sandro Iannaccone, such significant progress in motor recovery could only be achieved through a multidisciplinary approach that blends advanced neuromodulation techniques with personalized rehabilitation strategies.
