Brief Summary

To recover lower-limb motor function is a primary goal for rehabilitation after anterior cruciate ligament (ACL) reconstruction. Although quantitative testing and questionnaire evaluation provide a lot of valuable information, while functional magnetic resonance imaging (fMRI) provides a powerful method to assess functional connectivity (FC) involved in motor function recovery before and after receiving a novel combined rehabilitation training. However, our understanding of the FC changes during early rehabilitation after ACL reconstruction is partial and incomplete.

Outcome Measures

Primary Outcomes (2)

  • resting-stage fMRI

    Resting-stage fMRI images data acquisition was carried out in the Air Force Medical Center with a 3.0T MRI scanner (GE Discovery MR750, USA) using the echo planar imaging (BOLD) sequence for 6 min each time (TR/TE = 2000 ms/30 ms, matrix 64 × 64, FOV = 220×220mm2, number of slices = 36) with contiguous 3 mm slice thickness providing whole brain coverage. In addition, a series of anatomical images were also obtained during the first imaging session using T1-weighted 3D TFE sequence with 1×1×1mm resolution

    before and after 4 weeks

  • IKDC

    The IKDC score is a subjective knee assessment scale used to assess the level of knee function and severity of symptoms. The functional status of the knee joint is assessed by summing the scores for each item, converting the scores to a scale of 0 to 100

    before and after 4 weeks

Study Arms (1)

MI-BCI combined with tDCS

EXPERIMENTAL

The MI-BCI combined with tDCS treatment was performed five days per week (in the late afternoon)

Device: MI-BCI combined with tDCS treatment

Interventions

The treatment intervention was carried out in an independent and quite room and included following steps: During the MI-BCI based training, MI of leg flexion and extension training was first performed 10 times to accurate the training threshold, and then later in the formal BCI training, if the attention was reached the threshold, functional electrical stimulator was trigger to stimulate the corresponding muscle to execute the actual action. Additionally, the patient was given a brief training about how to operate tDCS device until he felt comfortable using it, and then asked to show and give feedback to the researcher. For motor function and pain improvement, tDCS is typically delivered with the anode electrode placed over the primary motor cortex (M1), and the cathode over the supraorbital area (SO) to trigger neuroplastic changes\[5\]. The MI-BCI combined with tDCS treatment was performed five days per week (in the late afternoon), and MI-BCI training for 30min.
