An American with paralysis of the lower extremities was able to stand up thanks to stimulation of the spinal cord, reports MedPage Today. A new method of rehabilitation was tested by a group of researchers led by Reggie Edgerton (Reggie Edgerton) from the University of California at Los Angeles (University of California, Los Angeles). Article researchers published in the journal The Lancet.
Rob Summers sustained a spinal injury during a traffic accident in 2006. As a result of spinal cord injury at the level of the seventh cervical and first thoracic vertebrae, a 20-year-old man developed lower paraplegia - paralysis of both legs. Rehabilitation of the musculoskeletal system, which the victim underwent for 26 months, did not produce results.
According to the authors of the study, most spinal cord injuries do not lead to complete damage to this organ, and in such cases the integrity of some nerve fibers is preserved. The Edgerton group suggested that, due to the electrical stimulation, the motor neurons that survived the injury would provide the movements of the lower limbs in the victim's spinal cord.
In December 2009, a team of surgeons from the University of Louisville, Kentucky, implanted 16 electrodes into Summers' spinal cord. The electrodes were implanted into the solid membrane of the brain from the first lumbar to the first sacral vertebra and connected to an electrical impulse generator that surgeons placed in the male abdominal cavity.
Doctors conducted 29 sessions of electrostimulation of the victim's spinal cord. The duration of one session ranged from 40 minutes to four hours. As a result, Summers was able to keep his own weight on his legs for four and a half minutes. After seven months of rehabilitation, the patient was able to get up on his feet from a sitting position.
The researchers noted that Summers could only perform these exercises during spinal cord electrostimulation sessions. At other times, scientists could not register the electrical activity of the muscles of the patient's lower limbs. According to the BBC, Edgerton and his colleagues have already selected four patients for further research on a new rehabilitation method.

Good afternoon, dear colleagues!
In this topic, the problem of electrostimulation in the treatment of such diseases as spastic cerebral palsy, spasms after strokes, spasms of the adductor muscles and other disorders associated with paralysis and paresis of acute genesis is suggested for discussion.
I have long been interested in this issue in terms of the possibility of using neuromodulation techniques.
Communicating with colleagues - colleagues on this topic, studying literary sources, I did not find definite answers and ready-made solutions on this topic. Collecting information on "bricks", I try to systematize this knowledge in order to create effective equipment and methods for the treatment of these diseases.

To start the dialogue, I propose to read the following material.
A practical example of the treatment of muscle spasticity with electric currents. In the mid-60s, in his book "Niederfrequente Ströme zur Diagnostik und Therapie" [Low-frequency currents for diagnosis and therapy] (1981, 2nd edition, Maudrich-Verlag) Dr. Jantsch and Hoefschmidt recommended a two-channel treatment of muscle spasticity, thus deriving , spasticity from the list of contraindications for electrotherapy. The fundamental principle of special electrotherapy, such as spastic cerebral palsy, spasms after strokes and spasms of the adductor muscles, is stimulation of the neuro-tendon spindles, which, in turn, is aimed at inhibiting muscle spasm at the bone marrow level. Immediately after inhibition of the affected muscle, antagonist muscles are stimulated by the second channel. In the video, Dr. Felipe Medina gives an example of adjuvant therapy.

When electromyostimulation of the spinal cord is used
Electromyostimulation comes to the aid of chronic pain syndrome, because steroid injections can not be used for a long time, because they can cause considerable damage:
- violation of the gastrointestinal tract,
- development of bone resorption,
- endocrine disorders, etc.
In 70% of cases, electrostimulation helped to relieve pain medication.
Indications for electrostimulation are:
- posttraumatic dystrophy,
- peripheral nerve damage
- spinal arachnoiditis,
- ischemic paralysis
- cerebral palsy, including cerebral palsy (cerebral palsy),
- para- and tetraparesis for dorsal herniation of the intervertebral disc,
- somatic disorders of neurological nature,
- phantom pains
- chronic radicular syndrome, etc.
- At the first stage, using an epiduroscopy method under local anesthesia, electrodes are inserted into the epidural space of the spinal cord.
- Visual observation with the endoscope video camera allows you to arrange them as accurately as possible.
- A trial test is conducted: for a certain time, the pain dynamics is analyzed - whether or not there is no reduction of pain under the influence of impulses.
- Experimentally determine the most optimal radiation parameters.
Contraindications for electromyostimulation
Complications with this procedure, if the system is introduced correctly, are relatively rare, but still the patient after the introduction of the endoscope may have not very pleasant feelings:
- feeling of pressure at the location of the endoscope,
- pain, paresthesia,
- clouding of consciousness for two or three minutes.
The nature of the possible complications:
- damage to the dura mater, nerve roots,
- infectious inflammatory processes and bleeding.
It is also possible allergies to drugs with side effects:
- reactive adhesions,
- numbness of the limbs
- pelvic dysfunction.
Clinical practice cases
The effectiveness of electrical stimulation is proven by joint research of Russian and American scientists.
In 2014, they investigated the effect of electrical stimulation on four men who had a terrible accident, which led to loss of sensitivity and impaired motor functions of the legs.
In the lumbosacral region of the epidural space of the spinal cord, in the area containing the large venous plexuses, they were implanted with electrodes imitating signals from the brain to motor neurons.
Patients soon had a very positive dynamic:
- restored motor functions of the legs,
- work of intestines and urinogenital system was adjusted,
- the muscular system has got stronger,
- improved health.
Electrical stimulation in the treatment of cerebral palsy
Electromyostimulation with cerebral palsy is effective in spastic paraparesis of the lower extremities, while the endoscope is inserted into the lumbar thickening.
Constant electrical stimulation for cerebral palsy is often practiced abroad in patients with:
- with spinal spastic paralysis,
- with multiple sclerosis,
- with severe post-traumatic consequences.
As a result of research of our scientists it was found out:
- The use of electrostimulation of the lumbar spine in patients with cerebral palsy reduced muscle spasms of not only the lower but also the upper limbs.
- As a result of the ensuing normalization of muscle tone, SCS stimulation could be stopped one or two years after the operation.
Cerebral palsy is treated very long and difficult. In treatment, in addition to electrical stimulation, neuromuscular blockades, neurosurgical operations, and physiotherapy methods are used.
But about this - in a separate article.
