    (Hanley & Belfus-elsevier inc, 2023) Karagözoğlu Coşkunsu, Dilber; Coskunsu, Dilber Karagozoglu; Akcay, Sumeyye; Akyol, Kubra; Hanoglu, Lutfu; Ozturk, Necla; Fizyoterapi Ve Rehabilitasyon Bölümü
    Objective: To investigate the effect of electromyography (EMG)-driven robotic therapy on the recovery of the hand in a stroke case lasting 9 years.Case: An 18-year-old patient with hemiparesis due to the ischemic lesion was admitted to our clinic with hand impairment. Fifteen sessions (5 weeks x 3 times) of robotic rehabilitation were applied with the Hand of Hope. Average EMG (mV) of flexor digitorum superficialis (FDS) muscle, average force (N) and the rate of force development (RFD)(N/s) were also assessed before and after the treatment following the 5th and 10th sessions and at the end of treatment. Also, Fugl-Meyer Assessment of Upper Extremity Scale (FMU-UE), Motor Activity Log (MAL), Canadian Occupational Performance Score (COPM) and Visual Analog Scale (VAS) were used for assessment before and after the treatment.Results: The average EMG measured from FDS increased from 0.093-0.133 mV. The average force and average RFD increased from 45.6-97.7 and from 135.6-172.6 respectively. While affected and/or unaffected side force ratio increased dramatically from 54%-82%, the FMA-UE score increased from 56-59. The MAL quality of use score increased from 3.93-4.13. Performance and satisfaction scores of COPM changed from 5.25-7.25 and 4.5-8.25 respectively. VAS score for fatigue changed from 6 to 4.Discussion: The improvement achieved 9 years later with 15 sessions of rehabilitation suggests that im-provement may be possible for chronic stroke patients.(c) 2021 Elsevier Inc.

    Effects of Robotic Rehabilitation on Recovery of Hand Functions in Acute Stroke: a Preliminary Randomized Controlled Study
    (Wiley, 2022) Karagözoğlu Coşkunsu, Dilber; Akcay, Sumeyye; Ogul, Ozden Erkan; Akyol, D. Kubra; Ozturk, Necla; Zileli, Fusun; Krespi, Yakup; Fizyoterapi Ve Rehabilitasyon Bölümü
    Objective The aim of this study was to investigate the effects of EMG-driven robotic rehabilitation on hand motor functions and daily living activities of patients with acute ischemic stroke. Materials & Method A preliminary randomized-controlled, single-blind trial rectuited twenty-four patients with acute ischemic stroke (<1 month after cerebrovascular accident) and randomly allocated to experimental group (EG) and control group (CG). Neurophysiological rehabilitation program was performed to both EG and CG for 5 days a week and totally 15 sessions. The EG also received robotic rehabilitation with the EMG-driven exoskeleton hand robot (Hand of Hope (R), Rehab-Robotics Company) 15 sessions over 3 weeks. Hand motor functions (Fugl-Meyer Assessment-Upper Extremity (FMA-UE) and Action Research Arm Test (ARAT)), activities of daily living (Motor Activity Log (MAL)), force and EMG activities of extensor and flexor muscles for the cup test were evaluated before treatment (pretreatment) and after the 15th session (posttreatment). Results Eleven patients (59.91 +/- 14.20 yr) in the EG and 9 patients (70 +/- 14.06 yr) in the CG completed the study. EG did not provide a significant advantage compared with the CG in FMA-UE, ARAT and MAL scores and cup-force and EMG activities (p > .05 for all). Conclusion In this preliminary study, improvement in motor functions, daily living activities and force were found in both groups. However, addition of the EMG-driven robotic treatment to the neurophysiological rehabilitation program did not provide an additional benefit to the clinical outcomes in 3 weeks in acute stroke patients.
