Objective Pelvic movements when walking should be objectively evaluated in the context of clinical data in order to understand the function of compensatory mechanisms in the onset and management of symptomatic degenerative lumbar stenosis (DLS). The purpose of this study was to compare patients treated with decompression surgery (DS) and patients with symptomatic DLS in terms of pelvic movements while walking.Materials and Methods A total of 107 participants were included in this study. 34 patients who underwent DS performed by the same surgeon were selected as the DS group, while 39 patients with DLS who required surgery were selected as the DLS group. The control group consisted of 34 age-matched healthy individuals who had no disease and no gait disorder. The BTS G-WALK sensor system (G-Walk) was used to measure pelvic movements (tilt, rotation, obliquity) and gait parameters (speed, cadence, stride length).Results DS and control groups had decreased maximum (p=0.008 and p=0.006, respectively) and minimum anterior tilt of the pelvis (p=0.015 and p=0.001, respectively) compared to the DLS group. There was no significant difference between the groups for rotation, oblique and tilt range of motion of the pelvis (p>0.05). Compared to the control group, speed during gait were significantly lower in both the DLS (p=0.012) and DS groups (p=0.016).Conclusions In this study, decompression surgery was found to affect pelvic movements. Patients with DLS walked differently from those who had no symptoms, and this difference usually disappeared following surgical decompression. Pelvic movements may serve as a helpful screening measure to identify early compensatory mechanisms.

Objective This study aims to investigate the effects of six weeks (three times a week) Wingate style high-intensity interval training (HIIT) on strength, proprioception, flexibility, laxity, performance, and body composition in subjects who have undergone anterior cruciate ligament (ACL) reconstruction with the hamstring autograft method.Material and Methods Within the scope of the study, 29 volunteers who had undergone hamstring autograft ACL reconstruction at least six months ago were randomized and divided into two groups HIIT (n=15) and control (n=14) groups. After the initial assessments, the Wingate style HIIT was applied to the experimental group three days a week for six weeks. The control group continued their normal lifestyle and exercise habits. After six weeks, final evaluations were made. After obtaining the subjects' demographic information, body composition was measured with Tanita. Then, knee laxity measurement with GNRB arthrometer, 30(degrees) and 60(degrees)proprioception assessed with an isokinetic dynamometer, muscle strength (quadriceps femoris, hamstring (concentric/eccentric) at 60(degrees)/sec and endurance measurements at 180(degrees)/sec were performed respectively. Sit and reach test for flexibility and performance (single leg jump, vertical jump, agility) parameters were measured.Results According to the findings, significant decrease in body composition (p 0.005), 180(degrees)/sec endurance strength increase (p > 0.005), and flexibility (p > 0.005) did not occur in the quadriceps and hamstring muscles better than control group.Conclusions With these results, it is thought that HIIT can be added to current physiotherapy programs as it provides positive enhancements in body composition, restoring muscle strength, operated side proprioception, and increasing performance parameters without increasing knee laxity after ACL reconstruction.
