About

The aim of this study is to compare the effects of robotic rehabilitation on balance, body control, mobility, spasticity, motor function and depression compared to traditional therapy in individuals with chronic stroke. Patients aged between 40-70 years, who applied to the Private Avrasya Hospital Physical Therapy and Rehabilitation Clinic, were diagnosed with hemiplegia based on an epicrisis medical board report, were included in the study on a voluntary basis, regardless of gender. After recording the demographic and clinical information of the participants, based on the physician's decision, they were included in 2 groups: conventional treatment combined with robotic rehabilitation (n=20) and conventional treatment only (n=20).

While one of the groups received traditional treatment, the other group received robotic walking training in addition to conventional treatment. Traditional treatment includes strengthening, balance, range of motion exercises and gait training applied 3 days a week for 4 weeks. Robot-assisted walking training was planned for 20 minutes, 3 days a week.

As assessment methods, number of steps, the 10m Walk Test, Brunnstrom motor staging, Functional Ambulation Classification, Fugl Meyer Rating Scale (lower extremity section), Modified Ashworth Scale, Beck Depression Scale, Tinetti Balance and Gait Test, Postural Assessment Scale in Stroke Patients and Stroke Impact Scale were used. Gender, age and duration of illness showed homogeneous distribution between the groups.

Full description

More than 80% of stroke survivors have impaired walking ability, but most regain their ability to walk. While 40% of them need help while walking, 60% of the group do not have the ability to move independently outside the home. Balance disorder is the most common problem after stroke. Decreased muscle strength and joint range of motion and impaired coordination and sensory organization mechanism prevent balance. 80% of individuals who have had a stroke for the first time have balance disorder in the subacute phase. As a result of restricted balance, postural control deteriorates, the risk of falling increases and mobility decreases.

Interventions to improve gait function should be intense, repetitive, and task-oriented. Intensive efforts of more than one physiotherapist are required in patients who do not have independent gait. Robot assisted walking devices; provides high-intensity, repetitive, task-specific therapy. It both reduces the workload of physiotherapists and improves gait quality, functional results (walking speed and capacity) and motor performance with multi-sensory stimulation.
