Conduction velocity, response latency and amplitude following electrical stimulation were investigated. Thirty male football players and 30 untrained males comprised the subject and control groups, respectively. We showed that professional football players have significantly slower sural nerve conduction velocity than untrained controls (p<0.05). Although we found no signs of neuropathy, mild changes in nerve conduction velocity were evident in the sural nerve of the players. Motor conduction velocity of tibial nerve was also significantly prolonged in this group when comparing dominant and non-dominant extremities (p<0.05). The tibial nerve muscle action potential amplitude was lower in the players' dominant limbs compared with the controls (p<0.05). We found no statistical difference in motor conduction velocities, distal latencies and amplitudes of the common peroneal nerve when comparing players and controls in both dominant and non-dominant limbs (p>0.05). Our results showed abnormalities of function in the sural and tibial nerves in football players compared with untrained controls, which may indicate early signs of neuropathy.

Our aim was to evaluate the metacarpal morphometry for retrograde intramedullary entrance and to determine the optimal entry point. Computed tomography images of 105 patients including 64 men and 41 women, were examined. Distal and proximal metacarpal widths, medullary cavity width, cortex thickness and the measurements of the optimal entry site in volar-dorsal and radio-ulnar directions were measured in both coronal and sagittal planes. In the sagittal plane, the second metacarpal had the widest proximal width (16.29 mm), distal width was greatest in the third metacarpal (14.34 mm) which was significantly different between the sexes (p<0.001). Third metacarpal had the widest medullary cavity width in the sagittal plane (4.12 mm). In the coronal plane, it was the second metarcarpal with the widest proximal (16.14 mm) and distal width (13.92 mm) and was also the longest (66.32 mm). Unlike the sagittal plane, the medullary cavity width in the coronal plane was at the widest (4.06 mm) in fifth metacarpal. The points determined for optimal entry were respectively (4.60 mm; 4.97 mm; 4.55 mm; 4.36 mm) in the dorsal-volar plane, close to the dorsal side. There was no significant difference between the sexes for optimal insertion point in the sagittal planes in all the measured metacarpals. Considering its three dimensional structure, metacarpal bones have irregular morphometric properties and these features differ in sagittal and coronal planes. The optimal entry site is located in the midline in the coronal plane, while it is located in the sagittal plane close to the dorsal part. Knowing these properties can reduce the complication rate by reducing entry attempts and help select the correct material.

Stories can be used as an advantageous tool, which makes information more rememberable by stimulating cognitive behavior. Material and Methods: In order to determine the efficiency of the storytelling technique on the effects of grade point average in the anatomy session, stories were told to term II medical students (n = 132) at the end of the theoretical neurological lesson. A questionnaire with 12 questions was distributed to the students belonging to the pilot study. Grade point average, as well as gender and age (mean: 19.95 ± 0.995) of the students was the other parameters. Results: More than 90% of the students agreed that storytelling helps them to understand the subject and more than 70% of the students agreed that storytelling helps them to gather their attention. Furthermore, the statistical comparison with the previous 2 years demonstrated that the grade point average of the storytelling years was higher than the others. Discussion and Conclusion: Therefore, we believe that incorporating a storytelling learning style into the traditional anatomy curriculum, will be advantageous for education and will have a positive effect on the grade average. If we are able to revive the story in the minds of the students, we think that the lessons will be more permanent in their memory.

Furthermore, as the routine sport training involving aerobic exercises provides a fit and adequate musculoskeletal structure, doesn’t affect the core stabilization muscles. Therefore, strengthless muscles and unstable lumbo-pelvik musculoskeletal system provoke pain in related anatomical region. In this context, we aimed to evaluate the statistical relationship between the ergonomic approach and lack of core stabilization exercises with musculoskeletal pains of athletes. Material and methods A total of 80 athletes participated in our work. Standardized ergonomic muscle and skeletal system pains questionnaires were applied to participants. Correlation tests were performed and statistically evaluated by comparing the parameters such as gender, age range, height, weight, and sports age period. Also 52,25% (n: 41) of athletes complain of lumbar pain. Core stabilization exercises were performed during six weeks. Initial VAS and final VAS were analyzed. Results In total, 88,75% (n = 71) of participants had complaints of pain related to musculoskeletal system during the last week. Age, height, weight, and age of sport showed significant correlations with pain complaints seen in some body regions as topographically (P

Eleven elite female handball players and nine elite female volleyball players were selected as subjects for the study. Arm and forearm segment movement in the backswing and acceleration phases of players performing the volleyball spike and the handball jump shot were evaluated. Video data were captured using two Sony 50Hz cameras and were digitized and analyzed using Simi Motion Analysis 5.5 program. In the backswing phase, there were significant differences in the angular width, velocity and acceleration between the volleyball players and handball players on the transverse, vertical, and sagittal planes of the motions (p<.01). In the acceleration phase, the statistically significant difference was found in the angular width of the arm segment motion on the transverse plane (p<.05). On the sagittal plane, the significant difference was found in the angular width, velocity, and acceleration of the arm motions between the volleyball and handball players (p<.05). These results suggest that volleyball players use vertical flexion more frequently, thus increasing the time to gain velocity. Handball players transfer the velocity used in horizontal flexion to the vertical flexion in a short period of time.

A person transmits more explicitly his/her thoughts that are about an event or a concept he/she experienced. The aim of this study was to reveal emotions and thoughts of 1st class students in nursing about Anatomy lesson. 62 people who are students at 1st class in Vocational School of Health Services in 2014-2015 academic year have attended to our study. In questionnaire anthropometric and demographic traits of them were asked. They were wanted to create a metaphor about anatomy by filling in the blanks in " Anatomy resembles ...../ Anatomy is like .... ; because ..... " At the end of the assesment it has been detected that 44 metaphors have been produced. In these metaphors the most produced are ocean, puzzle, etc. When we divide these metaphors into categories and investigate them, there is an accumulation in discovering/revealing category with 24 metaphors. We believe that the metaphors which the students will generate, determining how to be lectured theoretical and practical anatomy lessons in a way that students are able to comprehend, will guide them.

The aim of this study was to compare sensory nerve conduction velocities (SNCV) for median, radial and ulnar nerves in the wrist of computer users with the same parameters in controls who do not use computers regularly. Material and Methods: Twenty one male computer users (age: mean (M) = 28.3 years ± standard deviation (SD) = 7.5 years) and 21 male control subjects (age: M±SD = 24.1±4.6 years) were recruited for the study. Limb length and the perimeters of the dominant arm and forearm were measured for each subject. The neurophysiological study consisted of measuring sensory nerve conduction of the median, ulnar and radial nerves. Results: The sensory conduction velocities of both median and ulnar nerves were significantly delayed in the dominant arm of the computer users compared to the controls. In addition, sensory conduction velocity of the median nerve was significantly delayed in the dominant extremity of the computer users compared to their non-dominant extremity. Conclusions: This study shows that computer users have a tendency toward developing median and ulnar sensory nerve damage in the wrist region. Mechanism of delayed SNCV in the median and ulnar nerves may be due to sustained extension and ulnar deviation of the wrist during computer mouse use and typing. Reduced SNCV changes were more apparent on the dominant side of the median nerve. This may indicate the increased neural deficits related to an increased use of the dominant side. Further investigation is needed to determine how to reduce potential risk factors at this stage in order to prevent development of median or ulnar neuropathy in the long term computer users.

Araştırmaya Kocaeli ilinde bulunan 1937 seka spor kulübünün, futbol okulunda aktif bir şekilde antrenmanlara katılan gönüllü 19 erkek(yaş:11,52±0,51 yıl), (boy:145,10±6,23 cm), (ağırlık:36,12±4,82kg) katılmıştır. Futbolculara birbirini izlemeyen ayrı günlerde 2 farklı ısınma protokolü uygulanmıştır. Isınma protokolleri, akut olarak iki ayrı protokol şeklinde, sadece 5 dakika koşu ve ardından dinamik ısınma egzersizlerinden oluşan Protokol A(PA) ve 5 dakika koşu ardından yin-yoga statik germe egzersizleri+dinamik ısınma egzersizlerini içeren Protokol B(PB)'den oluşmaktadır. Futbolculara her ısınma protokolünden sonra dikey sıçrama, 30m sürat ve illinois çeviklik testlerini uygulanmıştır. Araştırmada elde edilen verilerin analizinde SPSS 22.0 programı kullanılmıştır. Bu çalışmada, PA uygulanan futbolcuların dikey sıçrama test sonuçları(32,32 ± 5,96 cm) ile PB uygulanan futbolcuların dikey sıçrama test sonuçları(30,68 ± 5,96 cm) arasında PA'de artış yönünde anlamlı farklılık bulunmuştur(p<0,05). Her iki protokol grubunun, Illinois çeviklik testi ve 30m sprint testi sonuçları arasında istatiksel olarak anlamlı bir farklılık bulunmamıştır(p>0,05). Sonuç olarak dinamik ısınma öncesi yapılan yin-yoga germe egzersizlerinin(PB) dikey sıçrama performansını düşürdüğü, sadece dinamik ısınmanın(PA) dikey sıçrama performansına akut dönemde daha etkili olduğu, 30m sprint performansında ve illinois çeviklik testinde ise iki ısınma protokolü arasında anlamlı bir fark olmadığı tespit edilmiştir. Buna bağlı olarak bu yaştaki çocuklara belirlenen amaç doğrultusunda ve kişi bazında ısınma protokollerinin oluşturulması ve bu protokollerde akut dönemde yin-yoga türü statik germe egzersizlerine yer verilmemesi daha doğru olacaktır.
