Contralaterally-controlled functional electrical stimulation-induced muscle contraction for severe lower extremity...

[Purpose] We describe a new method of functional electrical stimulation therapy for severe hemiparesis. Conventional functional electrical stimulation of the lower legs has limited applications. It is only suitable for patients who can monitor their muscle contractions, and it has complicated equipment installation procedures. [Participant and Methods] The participant was a male in his 40s with severe motor paralysis following brain surgery. We monitored the participant's healthy side using the external assist mode of an Integrated Volitional Control Electrical Stimulation (IVES^® OG Giken, Okayama, Japan) system while forcibly contracting the paralyzed side. The participant received this new functional electrical stimulation therapy five times per week. [Results] Two weeks after initiation of therapy, paralysis was noticeably improved, and motor function was maintained for approximately 1 year. [Conclusion] The outcomes of this case suggest that the addition of forced contraction therapy, mirror therapy, and repetitive exercise therapy to regular physical therapy may be beneficial. This treatment method may also be useful in postoperative patients with central motor palsy and no muscle contraction ability.
