Background: To date, reliability of ultrasound imaging (USI) measures of the abdominal muscles in children during the active straight leg raise (ASLR) test has not been confirmed. The aim of this study is to assess the intra-rater reliability of USI in measuring of the thickness and percent thickness change of the external oblique (EO), internal oblique (IO) and transversus abdominis (TrA) on both sides of the body during the ASLR test. Material/Methods: Thirty-two healthy children between 10-12 years old participated in the study. Three repeated USI measurements were recorded, in supine and resting positions and during the ASLR test. In supine position, measurements were collected at the end of normal expiration. In the case of ASLR, measurements were collected when the person undergoing examination touched the transverse delimiter with the distal part of the lower leg. A repeat session of the measurements was carried out 6 to 8 days later. Results: The use of mean value of the three repeated measurements showed that ICC3.3 fluctuated from 0.81 to 0.97 for OE, OI and TrA in resting position and during the ASLR test. In terms of percentage change of muscle thickness, the ICC3.3 result obtained for TrA, OE and IO were 0.86, 0.83 and 0.78, respectively. Conclusions: The USI evaluation of the lateral abdominal muscles thickness at rest has high reliability in children between 10-12 years old. The USI of the actual thickness and reflex activity of OE, OI and TrA during the ASLR test, based on three repeated measurements, is also reliable. It is recommended to perform three repeated measurements for children between 10-12 years old. There is still a need to seek solutions that will decrease the SDD value while evaluating the reflex activity of the lateral abdominal muscles during the ASLR test.

Background: In the physiotherapeutic practice, the need for measurements of e.g. range of motion or strength of the cervical spine muscles results from a variety of degenerative processes in the area of the head, cervical spine and shoulder girdle. In Poland, we designed a measurement stand based on the equipment described in foreign literature. Validation of the measurement stand was performed in order to determine the usefulness of this stand for measurements of maximal strength and muscle torques for the isometric contraction of the cervical spine muscles. Material/Methods: A group of 13 women was examined to validate the device. The criteria for inclusion into the study group were adult age, no back pain and head pain syndromes. Validation of the equipment consisted in the calculation of the intraclass correlation coefficient (ICC). Three measurements were performed for each movement in three planes: initial measurement (I), second measurement after 15 minutes (II) and the third measurement after a week (III). The ICC coefficient was calculated based on the methodology discussed in the study by Shrout and Fleiss (1979). Results: The results of the measurements reached the "excellent" level of the ICC coefficient between the first and the second test. In the case of the first and the third tests, the ICC coefficient reached the "good" level for the movements in the sagittal and transverse planes and the "excellent" level for the movements in the frontal plane. Conclusions: The measurement system used in the measurement stand designed by the authors of the present study can be successfully used for comparative studies of several groups or repeated examinations of the same study group after application of a specific therapeutic procedure.The stand cannot be used for evaluation whether the results obtained are consistent with the standards for specific populations or for comparison with the results obtained from other devices.
