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.

Time Difference Between Onsets of Lateral and Medial Hamstring Muscles During Gait in Patients With Patellofemoral Pain: a Preliminary Study
(Marmara Univ, inst Health Sciences, 2022) Karagözoğlu Coşkunsu, Dilber; Can, Filiz; Kuchimovs, Shavkat; Akalan, Nazif Ekin; Kilicoglu, I. Onder; Ozturk, Necla; Fizyoterapi Ve Rehabilitasyon Bölümü
Objective: Early activation of lateral hamstrings (LH) relative to medial hamstrings (MH) has been thought to be the cause of abnormal knee abduction and external rotation of the tibia, which affects the orientation of patellar tendon and increases lateral patellofemoral compression. Therefore, early activation of LH relative to MH is considered to have a role in the patellofemoral pain (PFP). The aim of this study was to investigate the time difference between MH and LH onsets in patients with PFP during gait. Methods: Thirteen patients with bilateral PFP (mean age 28.73 +/- 7.44 years) and 13 asymptomatic subjects (mean age 30.47 +/- 6.22 years) were recruited in the study. Gait analysis was performed using the ELITE system (BTS, Milano-Italy) with video cameras (TVC, BTS, Milano-Italy). Participants were requested to walk at a self-selected speed on a force platform, and EMG data were recorded from MH and LH muscles for 10 initial contacts by using TELEEMG (BTS, Milano-Italy). Time difference between the onsets of the MH and LH was calculated for each initial contact by using moving averaging method, then their mean was obtained for each participant. Results: The time difference between onsets of MH and LH was - 26.9 +/- 22.2 ms for PFP subjects and - 11.2 +/- 14.2 ms for control subjects, and LH mainly became activated earlier compared to MH in most of the subjects in both groups. There was a statistically significant difference between the time differences of the groups (p=0.041). Conclusion: Our findings suggest that LH displayed an earlier activation in subjects with PFP compared to control subjects during gait.
