Weakening iliopsoas muscle in healthy adults may induce stiff knee pattern

Objective The goal of the present study was to investigate the relationship between iliopsoas muscle group weakness and related hip joint velocity reduction and stiff-knee gait (SKG) during walking in healthy individuals. Methods A load of 5% of each individuals body weight was placed on non-dominant thigh of 15 neurologically intact, able-bodied participants (average age: 22.4 ± 0.81 years). For 33 min (135 s × 13 repetitions × 5 s rest), a passive stretch (PS) was applied with the load in place until hip flexor muscle strength dropped from 5/5 to 3+/5 according to manual muscle test. All participants underwent gait analysis before and after PS to compare sagittal plane hip, knee, and ankle kinematics and kinetics and temporo–spatial parameters. Paired t-test was used to compare pre- and post-stretch findings and Pearson correlation coefficient (r) was calculated to determine strength of correlation between SKG parameters and gait parameters of interest (p < 0.05). Results Reduced hip flexion velocity (mean: 21.5%; p = 0.005) was a contributor to SKG, decreasing peak knee flexion (PKF) (−20%; p = 0.0008), total knee range (−18.9%; p = 0.003), and range of knee flexion between toe-off and PKF (−26.7%; p = 0.001), and shortening duration between toe-off to PKF (−16.3%; p = 0.0005). Conclusion These findings verify that any treatment protocol that slows hip flexion during gait by weakening iliopsoas muscle may have great potential to produce SKG pattern combined with reduced gait velocity.

Scoliosis screening results of primary school students (11–15 years old group) in the west side of Istanbul

[Purpose] The present study aimed to find out the scoliosis prevalence 11–15 years old children and to create awareness about scoliosis. [Subjects and Methods] All of the children were assessed using the Adams Forward Bendings Test and a scoliometer. Sagittal plane changes such as kyphosis, lordosis, hypokyphosis, hypolordosis and anterior head tilt were screened. Children with trunk rotation angles (ATR) of 4 degrees or more were suspected of having scoliosis, and were evaluated for a second time for gibbosity height, arm-trunk distance, and ATR. [Results] A total of 2,207 children were screened and the evaluation revealed there were 11 girls (0.49%) with a Cobb angle of 10 degrees and more. The maximum Cobb angle was 43° (right thoracic-left lumbar) and the maximum ATR was 12°. Two children had kyphosis and lordosis, and one had hypokyphosis and was diagnosed as having idiopathic scoliosis. [Conclusion] Families should regularly check their children, even if they are not diagnosed as having scoliosis in school screenings. It is our opinion that our study increased the awareness of the families about scoliosis by screening, brochures and posters. In the future, if school screenings were performed as a routine procedure and scoliotic students were followed over the long term, the actual effectiveness of screening would be able to be detected.
