Combined Functional Electrical and Transcranial Direct Current Stimulation for Foot Drop (tDCS)

11 maja 2026 zaktualizowane przez: Saint Joseph's University, Philadelphia

Combined Functional Electrical and Transcranial Direct Current Stimulation for Foot Drop: A Case Series

This study aims to determine if combining the treatments of transcranial direct current stimulation (tDCS) and functional electrical stimulation (FES) will better help persons with stroke who have difficulty lifting their toes. As part of the treatment, subjects will receive electrical stimulation through pads on their scalp (similar to what one may have received in physical therapy previously to an arm or leg). This protocol is called transcranial direct current stimulation (tDCS). Subjects will also receive electrical stimulation through pads on their leg. This is called functional electrical stimulation (FES). During treatment sessions, subjects will also perform leg activity/strengthening exercises. The aim is to evaluate whether combining FES and tDCS within a PT session would reduce foot drop as indicated by improvements in the amount of toe clearance and ankle motion persons with stroke.

Eksperymentalny: FES and tDCS

The tDCS was applied as a bilateral montage with the anode of the tDCS device (ActivaDose II, ActivaTek Inc., Salt Lake City, Utah, USA) applied to the involved hemisphere and the cathode over the unaffected hemisphere. The dosage of the tDCS device was one mA for 60 minutes for the duration of the gait training delivered via a pair of sponge electrodes moistened with 0.9% NaCl solution. The exact locations for the electrode placements were based on a 20-point electrode system, in which we chose two points that targeted the motor cortex region corresponding to the left lower limb. Treatments were performed twice weekly over the 8 weeks.

The FES was administered to the tibialis anterior muscle of the impaired lower extremity with one electrode over the common peroneal nerve at the head of the fibula and the other over a motor point in the middle of the muscle belly of the tibialis anterior muscle.
Behawioralne: Standard protocol for combo of FES and tDCS
The gait training consisted of treadmill training with forward and backward ambulation with speed progression as appropriate, ambulation over obstacles, ramp ambulation forwards and backwards, and stair ambulation up and down. In each condition, cues were to increase toe clearance on the affected limb and achieve heel strike at initial contact. Vitals were collected at the start and end of each session, and heart rate was measured at the end of each activity, along with the Rating of Perceived Exertion (RPE), to determine whether the participant was working at a higher intensity than baseline.

The tDCS was applied as a bilateral montage with the anode of the tDCS device (ActivaDose II, ActivaTek Inc., Salt Lake City, UT, USA) applied to the involved hemisphere and the cathode over the unaffected hemisphere. The dosage of the tDCS device was set initially at one mA for 60 minutes and then for the duration of the gait training the machine was turned to subthreshold levels, delivered via a pair of sponge electrodes moistened with 0.9% NaCl solution. The exact locations for the electrode placements were based on a 20-point electrode system, in which we chose two points that targeted the motor cortex region corresponding to the left lower limb.

minimum toe clearance
Ramy czasowe: A pretest at baseline 2-3 days prior to the start of the intervention and then after 12 training sessions (between 6 and 8 weeks) posttests will occur 2-3 days after the 12th and final intervention is completed.
For the motion capture, participants were fitted with a modified Cleveland Clinic marker set where 4 clusters of 4 markers were attached to the thighs and shanks, and wand-mounted markers were also attached bilaterally to the anterior superior iliac spines (ASIS) and the sacrum. Additionally, seven 14 mm reflective markers were attached to the shoe at the upper ridge of the posterior surface of the calcaneus, sustentaculum tali, and lateral aspect of the calcaneus (peroneal tubercle); the heads of the first, second, and fifth metatarsals (MET); and the tip of the shoe/second digit if barefooted. Scores will vary by participant, and the key finding is the change in score from pre- to post-testing, indicating whether or not the intervention effected this change. Minimum value is 10 mm, max value is 40 mm, with a higher score indicating better and safer clearance.

Ramy czasowe: A pretest at baseline 2-3 days prior to the start of the intervention and then a posttest 2-3 days after the 12th and final intervention session is completed, 6-8 weeks after the training began.
Participants' perceived ability to safely perform a series of activities was rated on a percent scale. This indicator will vary, as sometimes prior to training, individuals are unaware of the concerns of falling, and then sometimes post-training, one is more cautious, and it can be vice versa as well. Thus, the goal is to look for patterns of change.
