Summary

Considering the paucity of studies on robotic hand therapy, larger-scale and long-term follow-up studies are needed. The aim in this study is to demonstrate the effectiveness of robot-assisted hand therapy in patients with chronic stroke and to compare this effectiveness in patients with different Brunnstrom stages.

Detailed description

Stroke is one of the leading causes of disability worldwide. Although mortality is decreasing, the number of people living with the effects of stroke has increased due to the increasing and aging population. It has been observed that 26% of patients have decreased basic daily living activities and 50% have decreased mobility after stroke. Effective therapy in stroke rehabilitation should include repetitive, functional and task-specific exercises performed with high intensity and duration. In this context, in addition to traditional treatments, many new treatment approaches have come to the fore in recent years. Robot-assisted treatment (RAT) is one of these new treatment approaches. The use of robotic technology in rehabilitation has gained importance especially in the last 15 years and developments in this regard continue to increase. RAT is an innovative approach that includes intensive, repeatable, interactive and personalized applications. This technology-based treatment increases the efficiency of rehabilitation care with its features of intensity, interaction, flexibility and adaptability to the patient performance and needs. It has no significant side effects and is well tolerated by patients. In the literature on robot-assisted treatment, different robotic devices have been used in various studies and different treatment protocols have been applied. This treatment has been reported to provide significantly greater improvement in function compared to conventional usual care. Studies in the literature on RAT demonstrate the feasibility of using these technologies in large patient groups. The most common and devastating consequence of post-stroke disability is functional disability in the upper extremity. The functional prognosis of the lower extremity is generally better than the upper extremity after stroke. 20-30% of patients can walk normally, and 75% can reach some stage of ambulation. However, only 5% of patients return to normal upper extremity function, while 23-43% show inadequate functional recovery. Therefore, upper extremity rehabilitation requires more time and effort than lower extremity rehabilitation. Bertani et al. In their published meta-analysis, they stated that robot-assisted rehabilitation is more effective in improving upper extremity motor function, especially in patients with chronic stroke, compared to conventional therapy. Amadeo (Tyromotion, Graz, Austria), an end-effector robotic rehabilitation device designed for hand rehabilitation, has shown feasibility and preliminary efficacy for stroke in the subacute phase. A randomized controlled trial with 17 patients compared conventional occupational therapy with Amadeo robotic therapy and after forty sessions, both groups showed significant improvement, but robotic intervention caused a greater improvement in hand function as measured by Fugl-Meyer and Motricity Index. Robotic hand therapy has started to take its place in routine rehabilitation protocols today. Considering the scarcity of studies on robotic hand therapy, it has been seen that larger-scale and long-term follow-up studies are needed. The aim in this study is to demonstrate the effectiveness of robot-assisted hand therapy in patients with chronic stroke and to compare this effectiveness in patients with different Brunnstrom stages.

Conditions

• Stroke
• Hemiplegia

Interventions

Type	Name	Description
PROCEDURE	robotic rehabilitation	In addition to conventional therapy, the robotic therapy group was planned to receive robotic rehabilitation with a hand-finger robot \[Amadeo (Tyromotion, Graz, Austria)\] for 45 minutes, accompanied by a physiotherapist trained in robotic rehabilitation and with at least 5 years of experience. A total of 20 treatment sessions will be applied 2 days a week.
PROCEDURE	conventional rehabilitation	It was planned for the conventional therapy group to receive an exercise program consisting of 45 minutes of active, passive range of motion exercises and strengthening exercises, accompanied by a physiotherapist with at least 5 years of experience in stroke rehabilitation. A total of 20 treatment sessions will be applied 2 days a week.
