    Comparison of asymmetries in ground reaction force patterns between normal human gait and football players
    (Inst Sport, 2004) Cigali, BS; Ulucam, E; Yilmaz, A; Cakiroglu, M
    The purpose of this study is to investigate the asymmetry of some temporal gait parameters and Ground Reaction Forces (GRF) in normal subjects and football players. 31 football players and 33 normal subjects participated in our study. The gait parameters were recorded by using an insole system. GRF values were recorded from the heel (Fmax1), middle feet (Fmax2), forefeet lateral side (Fmax3) and forfeet medial side (Fmax4). The subjects were asked to walk along an 8 in footpath and time versus force graphics recorded. Data were collected after exporting a worksheet program for percentage of swing and stance phase time (Tswing, Tstance), double support time (DST), and GRF values from four different parts of their feet and times to reach maximum force values (Tmax1, Tmax, Tmax3, Tmax4). Temporal parameters of both groups Tswing, T stance and DST have no statistical differences but they have no exact symmetry as well. All Fmax values were significantly high for the left side of the football players and in the control group only Fmax1 and Fmax4 were significantly high for the left side. Moreover, when comparing both groups, while for the left side Fmax3 and Tmax4 were significantly high for the football players group, Fmax1 was significantly low. For the right side only Fmax3 was significantly high for the football players. In conclusion, GRF values show asymmetry especially for the football players because of their stronger muscles coupled with the fact that they could stop and propel themselves into motion better than the control group.

    Measurement of tendon excursion velocity with colour Doppler imaging: A preliminary study on flexor pollicis longus muscle
    (Elsevier Sci Ireland Ltd, 1996) Cigali, BS; Buyruk, HM; Snijders, CJ; Lameris, JS; Holland, WPJ; Mesut, R; Stam, HJ
    Purpose: To study the use of colour Doppler imaging (CDI) for the measurement of maximum and mean tendon velocity, Recent studies showed that CDI, normally used for blood flow examinations, can be used for the imaging of tendons at the hand and wrist region. Although other modalities are available for imaging of the musculo-skeletal system, in vivo measurements of the velocity of tendon excursion are not possible. Methods: The flexor pollicis longus (FPL) tendon of 16 healthy volunteers was measured bilaterally at two levels (wrist and thenar), A sprint from the fingers along the proximal lower arm was applied, The thumb was fixed to the splint from the first phalanx to allow flexion of the interphalangeal (IP) joint only, Pulsed CDI was used for the measurements, The maximum and mean velocities of the FPL tendon were measured at spectrum display mode during continuous voluntary contractions, At least 10 sequential Doppler peaks (cm/s) were recorded at every trial, The measurements were repeated three times. Paired t-test and correlation coefficients were calculated between levels on the same side and the opposite side. Results: No significant differences were found between two levels of the same hand and of the opposite hand. As expected, the data revealed variations in the inter-individual tendon velocities, Conclusions: The velocity of the excursion of the FPL tendon can be measured with CDI with good reproducibility. It is expected that velocity measurements can be used in the future for the assessment of other tendons affected by various disorders.

    Musculus extensor digiti medii proprius and musculus extensor digitorum brevis manus - A case report of a rare variation
    (Blackwell Verlag Gmbh, 2002) Cigali, BS; Kutoglu, T; Cikmaz, S
    The musculus extensor digiti medii proprius and musculus extensor digitorum brevis manus are anomalous extensor muscles of the hand. During the routine dissection of a white male cadaver a musculus extensor digiti medii proprius was seen on both hands and a musculus extensor digitorum brevis Manus was seen on the left hand. The extensor medii proprius has a belly originating from the distal third of the ulna near the extensor indicis proprius and its tendon is inserted into the dorsal aponeurosis of the middle finger on both hands. On the left hand there was another anomalous muscle (musculus extensor digitorum brevis manus) which originated from the distal end of the radius, carpal ligaments and carpal joint capsule and inserted on the tendon of the extensor digiti medii proprius. This case is a multivariation of the hand extensor muscles and a musculus extensor digitorum brevis Manus inserting on the musculus extensor digiti medii proprius has not been reported previously.
