Introduction:
Electromyographic examinations with the use of surface leads (sEMG) in the standing and lying position are used in the diagnosis of musculoskeletal disorders and prognostically, assessing the patient’s therapeutic process, especially kinesiotherapy. There is little data on synergistic muscle function in patients with partial spinal cord injury (iSCI) from which an optimal isometric rehabilitation program can be determined.

Aim:
The aim of the following pilot study is to demonstrate the pathological pattern of synergistic interaction of lower limb muscles in patients with (iSCI) preventing correct posture. This is to enable the future to create a detailed algorithm through selective and targeted activities aimed at restoring the correct pattern of muscle synergy.

Material and Methods:
The studies were carried out in 12 patients with (iSCI) (documented in the MRI at levels C3-C8 and Th7-S1). The electrodes recorded bipolar activity (sEMG) on both sides of the: gluteus maximus (GM), rectus femoris (RF), tibialis anterior (TIB), extensors of the back of the foot (EXT). Records were performed in the position that activated the proximal and distal muscles.

Results:
The results show changes in the muscle synergy pattern for the lower extremities in patients with (iSCI), by the intensification of muscle interaction (GM) with (EXT).

Conclusions:
The results demonstrate the behavior of the synergistic muscle pathways of the distal muscles of the lower extremities and the role of the interacting with (GM) activity in maintaining correct posture. Kinesiotherapy exercises should be aimed at returning balance between (RE) and (GM) to restore the patient’s correct posture.
