PAS for Lower Extremity Rehabilitation in Tetraplegic Patients

May 12, 2025 updated by: Anastasia Shulga, Helsinki University Central Hospital

Long-term Paired Associative Stimulation for Rehabilitation of Lower Extremities in Persons With Incomplete Tetraplegia

The investigators have recently shown in incomplete SCI patients that long-term paired associative stimulation is capable of restoring voluntary control over some paralyzed muscles and enhancing motor output in the weak muscles (1,2). In this study, the investigators will administer long-term paired associative stimulation to patients with incomplete cervical level SCI and investigate its effectiveness for lower extremity rehabilitation.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: PAS
The intervention is given to peripheral nerve - motor cortex pairs selected by the investigator.
Device: Paired associative stimulation (with eXimia magnetic stimulator and Dantec Keypoint® electroneuromyography device)
Paired associative stimulation (PAS) administered several times per week for 8 weeks to lower limbs. PAS comprises transcranial magnetic stimulation (eXimia magnetic stimulator, Nexstim Ltd, Helsinki, Finland) and peripheral nerve stimulation (given with Dantec Keypoint® electroneuromyography device (Natus Medical Incorporated, Pleasanton, CA, USA)).
