Publication Metadata only The Efficacy of Tai Chi and Yoga in Rheumatoid Arthritis and Spondyloarthropathies: A narrative biomedical review(SPRINGER HEIDELBERG, 2018) AKYÜZ, GÜLSEREN DERYA; Akyuz, Gulseren; Kenis-Coskun, OzgeRheumatoid arthritis (RA) and spondyloarthropathies (SpA) are among the most common inflammatory rheumatic diseases, which might induce chronic pain for their sufferers. Mind-body interventions like Tai Chi and yoga are among the many alternative therapies for combatting chronic pain. This review aims to overview the articles about their effectiveness in RA and SpA. We searched PubMed/MEDLINE, Scopus, and Web of Science for English-language sources from their inception through September 2017. Case-control studies, interventional studies, and case series that included more than three cases and randomized crossover studies were included. The literature search retrieved 133 non-duplicate records, and 15 of them were eligible and were included in this review. The influence of Tai Chi remains debatable in RA, while there is only one study that investigated its efficacy in SpA. Yoga seems effective in decreasing pain and inflammation while increasing quality of life. There are no data available about its effect on SpA. Even after a thorough research, the number of articles is quite limited on the effectiveness of Tai Chi and yoga in RA and SpA. While these complementary approaches still show some promise as alternative therapies in RA and SpA, the literature lacks long-term studies with larger patient groups.Publication Open Access Assessment of the Relationships Between Spinopelvic Radiologic Parameters and Balance, Gait and Falls Efficacy in Patients with Postmenopausal Osteoporosis(GALENOS YAYINCILIK, 2018-12-01) AKYÜZ, GÜLSEREN DERYA; Giray, Esra; Akyuz, GulserenObjective: The aim of this study is to investigate the relationship between sagittal balance, spinopelvic parameters, bone mineral density, balance, and falls efficacy in postmenopausal osteoporosis patients. Materials and Methods: Forty patients between the ages of 40-80 with a diagnosis of postmenopausal osteoporosis were included in the study. Spinopelvic parameters (sagittal vertical axis (SVA), thoracic kyphosis, lumbar lordosis, pelvic tilt, pelvic incidence, sacral slope) were calculated from spine radiographs. Patients were applied Tinetti Balance and Gait Assessment and Falls Efficacy Scale. Relationship between bone mineral density measurements, clinical parameters, spinopelvic parameters, balance and gait, and falls efficacy were investigated. Results: Mean age of the patients was 63.42 +/- 8.98 and the mean L1-L4 T score was 2.5 +/- 0.68. Statistically significant negative correlation was found between the L1-L4 and L2-L4 vertebrae bone mineral density and T score, and sacral slope. Negative statistical correlations were found between SVA and Tinetti Balance and Gait Assessment balance subtest and total scores. There was no statistically significant relationship with other spinopelvic parameters. There was no significant correlation between SVA and spinopelvic parameters and Falls Efficacy Scale, while a statistically significant negative correlation detected between Falls Efficacy Scale and Tinetti Balance and Gait Assessment balance and gait subtests and total scores. Among the patients with normal, mild and severe deformity sagittal balance, there was statistically significant difference in terms of Tinetti Balance and Gait Assessment balance and gait subtests scores and total scores, while there was no difference with regards to Falls Efficacy Scale. Conclusion: In postmenopausal women with osteoporosis, SVA, sagittal balance parameters, and balance and gait functions were found to be associated.Publication Metadata only Ulnar nerve entrapment at wrist associated with carpal tunnel syndrome(ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2003) AKYÜZ, GÜLSEREN DERYA; Gozke, E; Dortcan, N; Kocer, A; Cetinkaya, M; Akyuz, G; Us, OIn this study, ulnar nerve entrapments at the wrist were investigated using nerve conduction studies in cases with established diagnosis of carpal tunnel syndrome (CTS). Cases with cervical radiculopathy and polyneuropathy as well as patients with ulnar nerve entrapment at elbow were excluded from the study. Fifty-three cases (46 females, seven males) whose ages ranged between 20 and 72 years (mean: 49.3 +/- 13.78) were evaluated. Among 53 cases, 12 (22.6%) bilateral and 41 (77.3%) unilateral CTS were detected. Totally 65 wrists evaluated and prolongation of median nerve wrist-3rd digit distal sensory latencies (DSL; n: 59; 90.7%) and wrist-abductor pollicis brevis distal motor latencies (n: 48; 73.8%) were seen. In six wrists, diagnoses were established with the detection of an increase in the differences between wrist-4th digit DSL of median and ulnar nerve. This test was used if other test results were in normal limits. Prolongation of ulnar nerve wrist-5th digit DSL were found in 12 wrists (18.4%) in cases with CTS. Among these 12 wrists mild (n: 2), moderate (n: 7) and severe (n: 3) CTS were detected. Ulnar nerve motor conduction studies provided normal results. In conclusion, we are in the opinion that for the detection of associated ulnar nerve wrist entrapments, ulnar nerve conduction studies paying special attention to DSL convey importance in established cases with CTS.

The aim of this study was to investigate the relationships between clinical instruments and transcranial magnetic stimulation (TMS)-evoked neurophysiological parameters in stroke patients. This study included 22 chronic post-stroke patients who were clinically assessed using the Motricity Index (MI), finger-tapping test (FTT), Motor Activity Log (MAL) 28, Brunnstrom motor staging and Ashworth Scale (ASH). Motor-evoked potential (MEP) latency and amplitude, resting motor threshold (rMT) and central motor conduction time (CMCT) were measured with TMS. Shorter MEP-latency, shorter CMCT, higher motor-evoked potential amplitude, and diminished rMT exhibited significant correlations with clinical measures evaluating motor stage, dexterity, and daily life functionality. rMT exhibited a negative correlation with hand and lower extremity Brunnstrom stages (r = -0.64, r = -0.51, respectively), MI score (r = -0.48), FTT score (r = -0.69), and also with amount of use scale and quality of movement scale of MAL 28 scores (r = -0.61, r = -0.62, respectively). Higher MEP amplitude and diminished rMT showed positive correlations with reduced ASH score (r = -0.65, r = 0.44, respectively). The TMS-evoked neurophysiologic parameters including MEP latency, amplitude, rMT and CMCT generally have positive correlation with clinical measures which evaluate motor stage, dexterity and daily life functionality. Additionally, spasticity has also remarkable relationships with MEP amplitude and rMT. These results suggest that TMS-evoked neurophysiological parameters were useful measures for monitoring post-stroke patients.Publication Metadata only A method for determining the grade of osteoporosis based on risk factors in postmenopausal women(SPRINGER LONDON LTD, 2005) AKYÜZ, GÜLSEREN DERYA; Ofluoglu, D; Gunduz, OH; Bekirolu, N; Kul-Panza, E; Akyuz, GThe aim of this study was to determine whether the probability of osteoporosis and osteopenia was affected by the risk factors, physical examination findings, or radiological investigations such as spinal X-rays in postmenopausal women. We assessed risk factors such as use of hormone replacement therapy, physical activity level, calcium intake, smoking, caffeine consumption, long-term immobilization, previous history of fracture, family history of fracture, presence of certain systemic diseases (hyperthyroidism or hyperparathyroidism), or use of medications (corticosteroids or others), physical examinations, and presence of vertebral fractures on spinal X-rays. Patients' bone mineral density (BMD) was evaluated using dual energy X-ray absorptiometry (DXA) in the lumbar spine, and we compared the risk factors between osteopenic and osteoporotic women according to DXA. We evaluated 235 postmenopausal women who attended our osteoporosis outpatient clinic. Those patients were divided into two groups as either osteopenic (n=67, mean age: 63.1 years) or osteoporotic (n=168, mean age: 66.2 years) according to WHO criteria. The lumbar spinal (L1-L2) T-score values were -1.5 +/- 0.6 and -3.1 +/- 0.6 in osteopenic and osteoporotic groups, respectively. There were significant differences between the two groups in terms of mean age and lumbar BMD (p=0.009 and p < 0.001, respectively). We also observed that vertebral tenderness on palpation, back pain, and existing vertebral fracture (fx) were significantly different between the osteopenic and osteoporotic groups (p < 0.05). As a result of the statistical analysis, we found an equation to determine osteopenic and osteoporotic women by using those four factors (age, vertebral tenderness on palpation, back pain, and existing vertebral fx) in multivariate stepwise logistic regression. The equation is as follows: Y (DXA) = -2.9024 + 0.044 (age in year) + 0.819 (vertebral fx) + 0.877 (pain) + 1.136 (vertebral tenderness). We can estimate whether a postmenopausal woman is osteopenic or osteoporotic based on these risk factors by using the stepwise logistic regression equation.Publication Open Access Fracture History in Osteoporosis: Risk Factors and its Effect on Quality of Life(AVES, 2015-01-15) AKYÜZ, GÜLSEREN DERYA; Kuru, Pinar; Akyuz, Gulseren; Cersit, Hulya Peynirci; Celenlioglu, Alp Eren; Cumhur, Ahmet; Biricik, Sefikcan; Kozan, Seda; Goksen, Aylin; Ozdemir, Mikail; Luleci, EmelBackground: Fractures are one of the main outcomes in osteoporosis and have an important effect on the general health status. Aims: The purpose of this study was to determine the effect of major fracture history on quality of life. We also investigated the important risk factors and their effect on bone mineral density and fracture history. Study Design: Cross-sectional study. Methods: We recruited 105 patients who were admitted to an osteoporosis outpatient clinic. Medical history, family history, calcium intake, physical activity level and biochemical tests were evaluated. Lumbar spine and femur neck bone mineral density were measured. The Qualeffo-41 questionnaire was also used for evaluating quality of life. Results: The average age of the 105 patients included in the study was 56.04 +/- 13.73 and 89% of them were post-menopausal women. The average body mass index was 26.84 +/- 5.99, which means that the women were overweight. Also, 48.5% of the patients were diagnosed with osteoporosis and 51.5% of them were diagnosed as low bone density. A total of 34 patients had a fracture history with minor trauma and some of the patients had more than one fracture (12 ankle and foot, 10 forearm, 9 vertebral, 4 hand, 3 hip, 2 rib, 1 tibial). When the patients with and without fracture history were compared, the mean Qualeffo-41 score in patients with fracture was 43.85 +/- 2.57 and in the non-fracture group was 36.27 +/- 2.01. Conclusion: Forearm, ankle and foot fractures can be commonly seen in osteoporosis patients with fracture history. We suggest that it is important to recognise osteoporosis prior to first fracture and disease-specific quality of life assessment should be done.Publication Metadata only Anatomy and Assessment of the Autonomic Nervous System(AVES, 2012) AKYÜZ, GÜLSEREN DERYA; Akyuz, Gulseren; Akdeniz Leblebicier, MerveAutonomic Nervous System (ANS) is responsible for the vegetative functions of the body. It is composed of many ganglions, plexi, cerebrospinal nuclei and nerves. ANS, which is also known as visceral or vegetative nervous system, helps to control many functions, such as blood pressure, gastrointestinal motility, glands, bladder functions, sweating and body temperature. ANS innervates all the smooth muscles and the heart, and keeps to stabilize body functions within certain limits. ANS is composed of 3 components: sympathetic system (thoracolomber-adrenergic), parasympathetic system (craniosacral- cholinergic) and enteric system (nonadrenergic- noncholinergic). Autonomic nerves are classified with regard to their origin from central nervous system, the distribution of peripheral ganglions, their various physiological effects on visceral organs, and response to pharmacological agents. It is essential to know the anatomy and the physiology of the ANS, in order to evaluate disorders, achieve the correct diagnosis and to plan accurate treatment.Publication Metadata only Comparison of the effectiveness of orthotic intervention, kinesiotaping, and paraffin treatments in patients with carpal tunnel syndrome: A single-blind and randomized controlled study(HANLEY & BELFUS-ELSEVIER INC, 2019) AKYÜZ, GÜLSEREN DERYA; Kaplan, Basak Mansiz; Akyuz, Gulseren; Kokar, Serdar; Yagci, IlkerPurpose: The aim of the study was to compare different conservative treatments in patients with carpal tunnel syndrome (CTS). Study Design: A single-blind randomized controlled study. Methods: Patients (n = 169) diagnosed with mild or moderate CTS were screened; 110 met study requirements. The patients were randomized into 3 groups. The control (CON) comparison provided to all patients was a fabricated night orthotic which held the wrist in a neutral position. The second group received adjunctive kinesiotaping (KIN) and the third group received paraffin (PARA). All patients were evaluated clinically, electrophysiologically, and ultrasonographically before treatment and at 3 weeks, 3 months, and 6 months. Results: There were 36 patients in CON, 37 in KIN, and 37 in PARA. Pain reduction in KIN was better than the other groups at 3 weeks (mean difference [MD] in CON 2.4 +/- 2.5, KIN 3.7 +/- 2.0, PARA 2.7 +/- 2.3; P < .01) and 6 months (MD in CON 3.4 +/- 3.0, KIN 4.9 +/- 3.1, PARA 3.7 +/- 2.9: P < .05). KIN pain reduction was better than CON at 3 months (MD in CON 3.8 +/- 2.8, KIN 5.0 +/- 2.5: P <.05). Reduction of the cross-sectional area of median nerve at the level of radioulnar joint was greater for KIN than CON at 3 weeks (MD in CON 0.0 +/- 0.5, KIN 0.3 +/- 0.7; P < .01) than PARA at 3 months (MD in KIN 0.3 +/- 0.8, PARA 0.0 +/- 0.8; P < .05) and both groups at 6 months (MD in CON 0.1 +/- 0.8, KIN 0.5 +/- 0.9, PARA 0.0 +/- 1.0 P < .05). Conclusion: Adding KIN to night use of an orthotic was more effective in achieving symptomatic and structural improvements than either the orthotic alone or adjunctive use of paraffin in patients with mild and moderate CTS.

We determined the normal values of SSR and RRIV in 23 (14 females, nine males) Turkish children aged 5 to 14 (mean 9.86, SD 2.48) years. SSR was recorded on the hands and feet during the electrical stimulation of both median and posterior tibial nerves, respectively. Similar response was elicited on both feet during the stimulation of the right median nerve. RRIV testing was performed during rest on the supine position and deep inspiration at a frequency of 6 times/min. The SSR was elicited in all children. The mean SSR latencies recorded on the feet during the stimulation of median or posterior tibial nerve were significantly more prolonged than those recorded at the hands (P < 0.001). There was no significant difference between the mean latencies of SSR recorded at the ipsilateral and contralateral palms or soles. The mean latencies recorded at the sole during stimulation of the median nerve were not significantly different compared to those that recorded at the sole during the posterior tibial nerve (P > 0.05). The SSR amplitudes were not assessed because of great variability and rapid habituation. The mean RRIV (46.54+/-11.29%) during deep breathing was significantly increased as compared to that (35.90+/-10.63%) during rest (P < 0.003). As a result, SSR and RRIV are preferred non-invasive tests for evaluation of autonomic nervous system in children. The SSR is useful and reliable if it is obtained in the optimum technical conditions. Further research is necessary to establish strict criteria for abnormality.Publication Open Access World Report on Disability: analysis of the disability issues and contributions of physical medicine and rehabilitation medical specialty in Turkey(BAYCINAR MEDICAL PUBL-BAYCINAR TIBBI YAYINCILIK) AKYÜZ, GÜLSEREN DERYA; Oral, Aydan; Aydin, Resa; Ketenci, Aysegul; Akyuz, Gulseren; Sindel, Dilsad; Yaliman, AyseWorld Report on Disability was prepared to facilitate the implementation of the United Nations Convention on the Rights of Persons with Disabilities which puts forward the requirement of full and effective participation of people with disabilities in the society as a human rights issue.
