Publication Open Access The effect of different body mass index levels on static and dynamic postural balance performance in adults(2023-01-01) TİMURTAŞ, EREN; SELÇUK, HALİT; DEMİRBÜKEN, İLKŞAN; POLAT, MİNE GÜLDEN; TİMURTAŞ E., SELÇUK H., Canoz E. U., Kortelli O. S., DEMİRBÜKEN İ., POLAT M. G.Purpose: It was aimed to estimate the static and dynamic postural balance performance in adults with different Body Mass Index (BMI) levels. Material and Methods: The study was conducted in Üsküdar Diabetes and Obesity Treatment Center between September and October 2021. Participants were divided into 5 groups according to BMI scores: normal-weight, overweight, 1st degree obese, 2nd degree obese, and 3rd degree obese. In addition, participants' static and dynamic balance performance were assessed by the Limits of Stability (LOS) and modified Clinical Test of Sensory Integration of Balance (m-CTSIB) tests. Results: For LOS parameters, there was a significant difference between groups in reaction time scores only for the backward direction (p<0.05). The endpoint and maximum excursion measurements except for the backward and directional control measurements except for the back and right were significantly different between groups, with the worst scores for 3rd degree obese group (p<0.05). For the m-CTSIB test, there was a significant difference between groups in all parameters except the eyes open condition on foam surface (p<0.05). Conclusion: The 3rd degree obese individuals are the most affected subgroup in dynamic balance. We recommended that rehabilitation and fall prevention programs primarily focus on 3rd degree obese individuals.

G.Publication Metadata only Ayak postürüne göre ayak bileği çevresi kas yapısının incelenmesi(2022-12-09) ÖZGÜL, BAHAR; DEMİRBÜKEN, İLKŞAN; POLAT, MİNE GÜLDEN; Özgül B., Aygün N. B., Demirbüken İ., Polat M. G.Amaç: Internal ve eksternal yumuşak doku yapıları, kuvvet ve dinamik destek uygulayarak ayak postürü üzerinde etkilere sahiptir. Bu çalışma kapsamında farklı ayak postürüne sahip bireylerde muskuloskeletal ultrasonik değerlendirmesiyle ile seçilen kasların yapısal karakterizasyonun gerçekleştirilmesi ve ayak bileği çevresinde yer alan majör kas gruplarının yapısal özelliklerinin karşılaştırılması amaçlandı. Yöntem: Otuz üç kadın olgunun (ortalama yaş: 21,45±1,60 yıl) dominant ayağı Ayak Postür İndeksi (APİ) uygulanarak değerlendirildi ve pron ayak postürüne sahip 15 olgu (APİ skoru = 6-10) ve normal ayak postürüne sahip 18 olgu (APİ skoru = 0-5) tespit edildi. Olguların tibialis anterior, gastrocnemius medialis ve peroneal kasların kalınlığı ve ek olarak peroneal kasların kesit alanı görüntüleri 5-13 MHz’lik bir prob ve Venue 40 ultrasonografik görüntüleme sistemi aracılığıyla toplandı. ImageJ programı kullanılarak üç farklı görüntünün ilgili yapısal özellikler analiz edildi ve ortalaması alındı. Ultrasonografik görüntüleme, uluslararası sertifikası olan ve beş yıldır muskuloskeletal ultrasonik görüntülemede tecrübesi olan fizyoterapist tarafından gerçekleştirildi. Bulgular: Her iki grupta yer alan olgular demografik özellikler açısından benzerdi (p>0,05). Pron ayak postürüne sahip bireylerin tibialis anterior (p=0,025, z=2,242), peroneus brevis (p=0,013, z=-2,459) ve total peroneus kas kalınlığının (p=0,007, z=2,639) normal ayak postürü grubundan daha fazla olduğu tespit edildi. Gastrocnemius medialis, peroneus longus kalınlığı ve peroneal kasların kesit alanı açısından gruplar arasında fark yoktu (p>0,05). Sonuç: Mevcut çalışmanın bulgularına göre, ayak postürüne göre ayak bileği hareketlerini kontrol eden tibialis anterior ve peroneal kasların kalınlığı farklılık gözlenmektedir. Daha fazla olgunun yer aldığı, ayak postürüne göre tendona aktarılan kuvvet hakkında daha detaylı bilgi verebilen penasyon açısının da değerlendirildiği ileri çalışmaların yapılması planlanmıştır.

E., AKGÜN İ., POLAT M. G.1. Introduction Diabetes which is a major health problem is related to impaired postural control due to peripheral neuropathy [1]. Obesity, another common health problem, is also found to be inseparably connected with postural instability. In particular, excessive body weight is demonstrated to significantly influence postural stability by altering center of mass position in the body. Impaired postural stability in T2DM and obesity has been documented separately by recent evidence [2,3]. We hypothesized that obesity would worsen the postural stability especially in adults who were diagnosed with T2DM. Therefore, the purpose of the current study was to investigate the possible impact of obesity on postural stability during quite standing in both obese and non-obese adults with T2DM. 2. Research question How does obesity influence the postural stability in adults with T2DM by means of sway velocity of center of mass during quite standing? 3. Methods The study was conducted at Fatih Sultan Mehmet Hospital Diabetes and Obesity Center in Istanbul, Turkey. Sixty-five adults (obese 37 adults with BMI ≥ 30 kg/m2 , non-obese 27 adults with BMI < 30 kg/ m2 ) who had no any musculoskeletal and neurological disorder were recruited. Modified Clinical Test of Sensory Interaction in Balance test among Balance Master System (NeuroCom, USA) was used to evaluate the postural stability. The sway velocity (degrees/second) of center of mass was measured on firm surface on firm and foam surface with eyes open (EO) and eyes closed (EC) conditions by the system. We created binary outcome according to normative scores. We performed logistic regression to estimate which groups has greater risk. 4. Results Number of people who had under normative scores in obese adults with diabetes; 14 (37,8%) in EO and 10 (27,0%) in EC on firm surface; 17 (45,9%) in EO and 34 (91,9%) in EC on foam surfaces; 26 (%70,3) in composite score. For non-obese adults with diabetes; 2 (7,4%) in EO and 8 (29,6%) in EC on firm surface; 9 (33,3%) in EO and 22 (81,5%) in EC on foam surfaces; 17 (%63,0) in composite score were determined. Obesity was higher risk eyes open scores in firm surface EO (OR:1.49 CI:1.13-1.96) but not in firm surface EC (OR:0.96 CI:0.70-1.32), firm surface with EO (OR:1.23 CI:0.82-1.84), firm surface with EC (OR:2.28 CI:0.60-8.75), composite score (OR: 1.26 CI:0.62-2.50). 5. Discussion Findings of current study revealed that obesity in T2DM is an important concern for deteriorating postural stability during quite standing. Interestingly standing with more demanding conditions as foam surface and/or eyes closed did not disturb postural sway of remarkable distinct percentages. It is noteworthy to pronounce that maintaining normal body weight in T2DM would encourage better postural stability in quite standing. An understanding of the obesity and its effect on postural stability in T2DM would provide another aspect for future intervention approaches for this population.Publication Open Access Robot-assisted therapy for upper extremity rehabilitation in Erb-Duchenne palsy: A case report(2020-10-01) AVCI, ENDER ERSİN; AKGÜN, İREM; TİMURTAŞ, EREN; DEMİRBÜKEN, İLKŞAN; POLAT, MİNE GÜLDEN; Akgün İ., Avcı E. E., Timurtaş E., Demirbüken İ., Polat M. G.Erb-Duchenne palsy (EDP), happens during a difficult birth due to the lesion in the upper brachial plexus (involving 5thand 6th, and rarely 7th cervical nerve roots), is characterized by muscle weakness and loss of motor functions in the affected upper extremity. While some injuries are temporary with full recovery, some may be lifelong resulting in significant functional limitations in daily life [1]. Various conservative rehabilitation approaches including muscle strength and range of motion training in upper extremity have been widely used in rehabilitation clinics [2]. Robot-assisted therapy (RAT) as an intervention for upper extremity rehabilitation is an encouraging approach in order to improve upper limb function in patients with neurological impairments [3]. RAT would offer motivational and intensive rehabilitation for a pediatric patient with EDP to interact and train with task-related games in the robotic devices.Publication Open Access The relationship between ankle eversion to inversion strength ratio and postural balance control in healthy individuals(2020-10-01) AVCI, ENDER ERSİN; AKGÜN, İREM; POLAT, MİNE GÜLDEN; TİMURTAŞ, EREN; DEMİRBÜKEN, İLKŞAN; Avcı E. E., Şenocak E., Akgün İ., Timurtaş E., Demirbüken İ., Polat M. G.The distal part of the lower extremity, foot and ankle joint, has an essential role to control postural balance through coordinated movements. The role of co-contraction between ankle dorsiflexor and plantar flexor muscles in maintaining postural balance has been mostly focused on previous researches [1,2]. However, the ankle strategy for postural control primarily occurs through eversion and inversion effort to keep the foot stable on the ground [3]. The current study aimed to investigate the relationship between isometric muscle strength ratio of eversion/ inversion (E/I) and postural balance control which is firstly corrected by ankle joint strategy.Publication Open Access Exoskeleton-assisted upper limb rehabilitation after stroke: a randomized controlled trial(2024-01-01) AKGÜN, İREM; DEMİRBÜKEN, İLKŞAN; TİMURTAŞ, EREN; POLAT, MİNE GÜLDEN; AKGÜN İ., DEMİRBÜKEN İ., TİMURTAŞ E., Pehlivan M. K., Pehlivan A. U., POLAT M. G., Francisco G. E., Yozbatiran N.Objectives: The upper-limb exoskeleton training program which is repetetive and task-specific therapy can improve motor functions in patients with stroke. To compare the effect of an upper-limb exoskeleton training program with Bobath concept on upper limb motor functions in individuals with chronic stroke. Methods: Participants were randomly assigned to exoskeleton group (EG, n = 12) or to Bobath group (BG, n = 12). Interventions were matched in terms of session duration and total number of sessions and performed 2 times per week for 6-weeks. Primary outcome was Fugl-Meyer- Upper Extremity (FMA-UE). Secondary outcomes were Modified Ashworth Scale (elbow and wrist flexor muscles), Motor Activity Log-30 which is consist of two parts as an amount of use (AOU) and quality of movement (QOM), and The Nottingham Extended Activities of Daily Living (NEADL) index. Results: After 12-sessions of training, the mean (SD) FMA-UE score increased by 5.7 (2.9) in the EG, and 1.9 (1.5) points in the BG (p <.05). In total, 40% of participants (5/12) demonstrated a clinically meaningful improvement (≥5.25 points) in the FM-UE, while none of the participants reached MCID score in the bobath group. Changes in the AOU, QOM, and NEADL were significantly larger in the EG compared to BG (p <.05). 7/12 (58.33%) of participants for AOU and 5/12 (42%) of participants for QOM in the EG showed that clinically meaningful change. 5/12 of participants (42%) in the EG demonstrated ≥4.9-point increase in NEADL score. Discussion: High-intensity repetitive arm and hand exercises with an exoskeleton device was safe and feasible. Exoskeleton-assisted training demonstrated significant benefits in improving upper limb functions and quality of life in individuals after stroke.
