TL;DR: Modified FRT is useful and reliable method to measure the sitting balance in subjects with spinal cord injury and the one-way ANOVA demonstrated that reach differed between groups with lower thoracic lesion and the other test groups.
Abstract: In general, sitting balance is decreased in subjects with spinal cord injury. The purpose of this study was to evaluate the inter- and intra-rater reliability of the Functional Reach Test (FRT) which is used to measure sitting balance. The subjects of this study were 26 persons with spinal cord injury, and they were divided into three groups according to their injury level. Group I, II and III consisted of the following quadriplegics, , and paraplegics, respectively. Subjects sat on a mat table that was set at an 80 degree inclination. During three sessions, the length subjects could reach in the FRT test was measured by three physical therapists, and compared to each other. The results showed that intraclass correlation coefficients (2,1) were above 0.97 and inter-rater difference was not statistically significant. The one-way ANOVA demonstrated that reach differed between groups with lower thoracic lesion and the other test groups. In conclusion, we think modified FRT is useful and reliable method to measure the sitting balance in subjects with spinal cord injury.

TL;DR: In this article, the reliability of aircraft electronic equipment between usage data and field data is investigated using MIL-HDBK-217, and the results show that the predicted reliability of MILHDBk-217 is more conservative (underestimated) than that of field data and usage data.
Abstract: Before an aircraft is delivered to customers, manufacturers have to verify required reliability for the aircraft In usual, reliability of electronic equipments in military aircraft are predicted based on MIL-HDBK-217 But the specification has not been revised since 1995 Some alternatives including SR-332 and 217PLUS are suggested in this study The processes and methods specified in MIL-HDBK-217 are compared with those of SR-332 Additionally, the predicted reliability of aircraft electronic equipment between usage data and field data are investigated using MIL-HDBK-217 The results show that predicted reliability of MIL-HDBK-217 is more conservative (underestimated) than that of usage data and field data

TL;DR: In this paper , the effects of upper limb resistance exercise on the sternum in patients following their first cardiac surgery via median sternotomy were investigated using a pretest-post-test design.
Abstract: Abstract Objective The purpose of this study was to determine the safety and feasibility of subacute upper limb resistance exercise on sternal micromotion and pain and the reliability of sternal ultrasound assessment following cardiac surgery via median sternotomy. Methods This experimental study used a pretest–posttest design to investigate the effects of upper limb resistance exercise on the sternum in patients following their first cardiac surgery via median sternotomy. Six bilateral upper limb machine-based exercises were commenced at a base resistance of 20 lb (9 kg) and progressed for each participant. Sternal micromotion was assessed using ultrasound at the mid and lower sternum at 2, 8, and 14 weeks postsurgery. Intrarater and interrater reliability was calculated using intraclass correlation coefficients (ICCs). Participant-reported pain was recorded at rest and with each exercise using a visual analogue scale. Results Sixteen adults (n = 15 males; 71.3 [SD = 6.2] years of age) consented to participate. Twelve participants completed the study, 2 withdrew prior to the 8-week assessment, and 2 assessments were not completed at 14 weeks due to assessor unavailability. The highest median micromotion at the sternal edges was observed during the bicep curl (median = 1.33 mm; range = −0.8 to 2.0 mm) in the lateral direction and the shoulder pulldown (median = 0.65 mm; range = −0.8 to 1.6 mm) in the anterior–posterior direction. Furthermore, participants reported no increase in pain when performing any of the 6 upper limb exercises. Interrater reliability was moderate to good for both lateral–posterior (ICC = 0.73; 95% CI = 0.58 to 0.83) and anterior–posterior micromotion (ICC = 0.83; 95% CI = 0.73 to 0.89) of the sternal edges. Conclusion Bilateral upper limb resistance exercises performed on cam-based machines do not result in sternal micromotion exceeding 2.0 mm or an increase in participant-reported pain. Impact Upper limb resistance training commenced as early as 2 weeks following cardiac surgery via median sternotomy and performed within the safe limits of pain and sternal micromotion appears to be safe and may accelerate postoperative recovery rather than muscular deconditioning.
