The purpose of this study is to investigate the implementation of a novel gait rehabilitation stimulus (G-EO System) that could advance current clinical practices. The goal is to establish the safety and feasibility of gait training using the G-EO System as well as investigating the impact on mobility, function, quality of life, and participatory outcomes.

Research Design: We propose a single-blinded, randomized trial of electromechanically-assisted gait training using the G-EO System in patients with Parkinson's disease with gait disability.

Specific Aim 1 will establish the safety and feasibility of gait training using the G-EO System.

Specific Aim 2 will determine the efficacy of gait training using the G-EO System for improving mobility, function, and quality of life

Visão geral do estudo

Descrição detalhada

Individuals diagnosed with Parkinson's disease (PD) often suffer from difficulties with gait initiation, maintaining a consistent kinematic gait pattern, and transitions between gait environments. Focused gait training that provides an environment that can emphasize motor control improvement in these deficits would be ideal for building a rehabilitative foundation for gait recovery for individuals with PD.

One approach that has been used to maintain and restore function in other neurological populations with severe disability is gait rehabilitation using treadmill training. This approach allows for specific and repetitive practice of walking movement and can involve therapist or electromechanical assistance. There is preliminary evidence from two small, uncontrolled studies supporting the benefits of therapist-assisted treadmill training on walking, balance, fatigue, spasticity, muscle strength, and quality of life in patients with PPMS and SPMS. Nevertheless, therapist-assisted gait training can require up to three trainers per patient making it burdensome and inefficient in the clinical setting. The intensity of manual treadmill training is low (i.e., <1.5 METs) based in part on the physical capacity and fitness level of the trainers, yet physiological adaptations for optimizing outcomes require moderate or vigorous intensity exercise.

Robotic-assisted gait training (RAGT) addresses many of the limitations of therapist-assisted gait training and can be performed using either exoskeleton or end-effector devices. Exoskeleton devices involve programmable drives or passive elements which physically move the lower limbs, whereas, end-effector approaches involve driven footplates that have trajectories that simulate the stance and swing phases. The G-EO System (Reha Technology AG: Olten, Switzerland) is a novel end-effector robotic gait training system that was developed for regaining mobility and independence in stroke survivors. This system involves minimal therapist and patient burden (e.g., quick set-up, single operate usage), there is the unique capacity for practicing walking and stair climbing movements, and the patient can receive real-time visual feedback. Gait training using the G-EO System has been applied in patients with stroke, Multiple Sclerosis (MS), and cerebral palsy (CP). These studies have established safety and feasibility, and preliminary evidence for benefits on mobility and function. For example, two studies involving 4 weeks of G-EO training with conventional physical therapy in non-ambulatory subacute stroke patients reported improved gait, stair climbing ability, leg strength, and activities of daily living (ADL) compared to physical therapy alone. There is limited RAGT studies evaluating the impact of this type of training for individuals with PD. The potential focus on improved gait kinematics may be of particular benefit for PD patients who often struggle with maintain step length and initiation.

The logistic advantages and advanced training capabilities of the G-EO System, as well as the benefits reported in other populations, support this strategy as an effective rehabilitation tool for restoring and maintaining function in Parkinson's disease. This approach represents an opportunity for improving current clinical practices for patients with Parkinson's disease. If successful, this project will provide initial evidence for increasing patient access to the G-EO System, and this could be accomplished through "regional technology centers" using a rural health-delivery approach.

The purpose of this study is to investigate the implementation of a novel gait rehabilitation stimulus (G-EO System) that could advance current clinical practices. The goal is to establish the safety and feasibility of gait training using the G-EO System as well as investigating the impact on mobility, function, quality of life, and participatory outcomes.

Research Design: We propose a single-blinded, randomized trial of electromechanically-assisted gait training using the G-EO System in patients with Parkinson's disease with gait disability. Enrolled participants will be randomized to either conventional physical therapy (CPT) or CPT with G-EO training. Participants will complete baseline assessments on Day 1 and then be scheduled for the intervention phase of the study. Regardless of group allocation, each participant will receive 12 total visits scheduled ideally for twice a week for 6 weeks. Within one week of completing the 12th physical therapy visit, participants will repeat the outcome assessments (post-intervention timepoint). Participants will then be asked to return 30 days later for a final outcome assessment (one month follow-up timepoint).

Specific Aim 1 will establish the safety and feasibility of gait training using the G-EO System.

Specific Aim 2 will determine the efficacy of gait training using the G-EO System for improving mobility, function, and quality of life.

Experimental: Conventional Physical Therapy (CPT) Group with G-EO Training (CPT-GEO)

CPT-GEO sessions will involve a warm-up using a cycle ergometer or treadmill walking, stretching, progressive strength training exercises, and balance training. Gait training will be administered using end-effector gait training protocols (G-EO trainer). Training will be administered 2 times per week for 40-60 minutes for six weeks.

Therapists will use traditional methods of neurological rehabilitation for improved gait and balance. These approaches will include stretching, strengthening, therapeutic exercises, balance training, and over-ground walking

The G-EO Gait Trainer uses distal fixation to promote a gait recovery by facilitating a controlled walking environment that includes an over-ground pattern and stair climbing. In addition, the device provides body position control to enable the patient to concentrate on the cyclical motion of walking without the fear of falling. Physical therapists can control different parameters of the gait cycle through computerized adjustments and the training setting can be manipulated to engage patients in active participation.

Mini-Balance Evaluation Systems Test (MiniBESTest) - Anticipatory Subscale
Prazo: Baseline, Post-Intervention (within 1 week after last therapy session), and 30 days after Post-intervention Visit

The Mini-Balance Evaluation Systems Test (MiniBESTest) is a performance-based measure of dynamic balance. The Anticipatory subscale assesses anticipatory postural adjustments during functional movement. Item scores are summed to produce a subscale score ranging from 0 to 6 points. Higher scores indicate better balance performance and lower scores indicate greater balance impairment.

Baseline, Post-Intervention (within 1 week after last therapy session), and 30 days after Post-intervention Visit
Mini-Balance Evaluation Systems Test (MiniBESTest) - Reactive Postural Control Subscale
Prazo: Baseline, Post-Intervention (within 1 week after last therapy session), and 30 days after Post-intervention Visit

The Mini-Balance Evaluation Systems Test (MiniBESTest) is a performance-based measure of dynamic balance. The Reactive Postural Control subscale assesses the ability to recover balance following an external perturbation; examining the effectiveness of compensatory stepping response. Item scores are summed to produce a subscale score ranging from 0 to 6 points. Higher scores indicate better balance performance and lower scores indicate greater balance impairment.

Parkinson's Disease Questionnaire-39 (PDQ-39) Summary Index Score
Prazo: Baseline, Post-Intervention (within 1 week after last therapy session), and 30 days after Post-intervention Visit

The Parkinson's Disease Questionnaire-39 (PDQ-39) is a 39-item, disease-specific questionnaire assessing health-related quality of life in individuals with Parkinson's disease. It includes eight domains: Mobility, Activities of Daily Living, Emotional Well-being, Stigma, Social Support, Cognitions, Communication, and Bodily Discomfort. Each item is scored from 0 to 4, with higher scores indicating greater difficulty. Individual domain scores are calculated by summing item responses, dividing by the maximum possible domain score, and multiplying by 100. Each domain ranges from 0 to 100. The PDQ-39 Summary Index is calculated as the unweighted mean of the eight domain scores and ranges from 0 to 100. Lower scores indicate better health-related quality of life, while higher scores indicate worse health-related quality of life.
