Robot-assisted gait training can improve gait ability of patients with Parkinson's disease by repeating a normal gait pattern with high intensity. This study is a randomized controlled trial to investigate the effect of robot-assisted gait training on walking ability and functional connectivity of brain in patients with Parkinson's disease using an exo-skeletal robot.
Parkinson's disease is a disease caused by dopamine deficiency in the striatum resulting from the loss of dopaminergic neuronal cells in the cerebral substantia. It is a progressive neurodegenerative disease characterized by motor symptoms including gait disturbance and balance instability. In the early stages of Parkinson's disease, dysfunction of the sensorimotor area of the basal ganglia typically occurs, leading to habitual control hurdles. Accordingly, cognitive efforts are required to perform habitual tasks such as walking, and the automaticity of walking is reduced. Walking performance in a dual-task condition has been used to assess gait automaticity in patients with Parkinson's disease.
Patients with Parkinson's disease are known to exhibit changes in functional connectivity of the brain from an early stage. In addition, a number of studies have reported that patients with Parkinson's disease with gait freezing have a change in resting brain activity and functional connectivity of the brain. However, no studies have examined the functional connectivity of the brain in patients with Parkinson's disease before and after rehabilitation.
Robot-assisted gait training is a method of rehabilitation that repeats normal gait patterns at high intensity. Recent meta-analysis has shown that robot-assisted gait training improved the recovery of independent gait after stroke compared with conventional rehabilitation therapy. On the other hand, robot-assisted gait training in Parkinson's disease has been reported to improve walking speed and walking endurance compared to conventional physical therapy, but is not superior to treadmill exercise of the same intensity. In addition, it has been reported that in patients with Parkinson's disease with balance impairment, robot-assisted gait training can improve balance disorder compared with physical therapy, and gait freezing has improved in some small-scale patients. However, studies on the effectiveness of robot-assisted gait training in Parkinson's disease are still lacking, and the mechanism of the effect has not been elucidated. In particular, the effect on gait automaticity, which is a characteristic of Parkinson 's disease, and functional connectivity of the brain has not been studied. Therefore, this study is aimed to investigate the effect of robot-assisted gait training on walking ability and functional connectivity of brain in patients with Parkinson's disease using an exo-skeletal robot.

| Robot-assisted gait training | Device | Patients should use their belts (Harness) to support their weight when walking in equipment. In the first training session, the patient focuses on fitting and adapting the equipment and helps the patient learn. To minimize skin damage, the patient can wear a protector. The initial walking speed starts at 1.0 km/h and can be increased gradually to 3.0 km/h. The gait robot provides an auditory feedback according to gait cycle and a visual feedback on the patient's active participation. If the patient can tolerate, the gait robot may control the walking speed automatically according to the patient's participation. The treatment time per session is 45 minutes including don and doff time. Total 12 sessions are provided for 4 weeks. |

| Intensive treadmill training | Device | Patients exercise on the treadmill. The initial walking speed starts at 1.0 km/h and can be increased gradually to 3.0 km/h. The therapist provides appropriate visual and auditory instructions to allow the patient to participate in the treadmill training. The treatment time per session is 45 minutes including warm-up and cool-down. Total 12 sessions are provided for 4 weeks. |

| Berg balance scale | The Berg balance scale is used to objectively determine a patient's ability (or inability) to safely balance during a series of predetermined tasks. It is a 14 item list with each item consisting of a five-point ordinal scale ranging from 0 to 4, with 0 indicating the lowest level of function and 4 the highest level of function (Maximum score 56). | baseline, at 4 weeks, at 8 weeks |
| Timed-up & go test (sec) | baseline, at 4 weeks, at 8 weeks |
| Korean version of Falls Efficacy Scale-International | The FES-I is a 16-item questionnaire of fall-related self-efficacy. The 16 items of the FES-I are rated according to "how concerned you are about the possibility of falling", using the following responses (score in parentheses): not at all (1), somewhat (2), fairly (3), and very concerned (4). Thus, the total score ranges from 16 to 64 points. | baseline, at 4 weeks, at 8 weeks |
| New Freezing of Gait questionnaire (NFOG-Q) - Part I | Part I detected the presence of FOG using a dichotomous item in which individuals were classified as a freezer (FR) or a non-freezer (NFR) if they had experienced FOG-episodes during the past month. | baseline, at 4 weeks, at 8 weeks |
| New Freezing of Gait questionnaire (NFOG-Q) - Part II, III | Parts II and III were designed for FRs only, providing a total summed score between 0 and 28. Part II (items 2-6, scoring range 0-19) rated the severity of FOG based on its duration and frequency in its most common manifestation, i.e. during turning and initiation of gait. Part III rated the impact of FOG on daily life (items 7-9, scoring range 0-9). No separate on and off rating of parts II and III was considered to avoid unreliable assessment. | baseline, at 4 weeks, at 8 weeks |
