Influence of surgical treatment of selected malignant tumours on gait kinematics – a pilot study

Abstract

Introduction. Assessment of the influence of surgical treatment of selected malignant tumours on gait kinematics. Methods. The study involved 115 patients of the Lower Silesian oncology Centre in Wroclaw, Poland (95 women and 20 men), mean age 58.39 ± 11.14 years, treated surgically for diagnosed cancer (group A: breast cancer; group B: reproductive cancer; group C: gastrointestinal cancer). Gait measurements were performed with the BTS G-Walk accelerometer before and after the surgery (5 th-6 th postoperative day). The t-test for dependent samples and analysis of variance-least significant difference test-were applied. Results. A significant decrease in cadence and walking speed was observed, by 7.9% (p < 0.001) and 17.5% (p < 0.001) in group B, and by 4.0% (p < 0.001) and 11.7% (p < 0.001) in group C, respectively. Additionally, there was an upward trend for symmetry of pelvic tilt in the sagittal plane (67.9% vs. 76.7%, p = 0.09) in group A, and a significant difference in pelvic deflections in the frontal plane (94.8% vs. 88.1%, p = 0.02) in group C. Statistically significant differences were found in walking cadence between groups A and B (p = 0.002), and in walking speed between group A and groups B and C (group A vs. B: p < 0.001; group A vs. C: p = 0.03). Conclusions. in patients treated surgically for reproductive system and gastrointestinal cancers, a decrease in time and space parameters of gait was demonstrated. Additionally, in patients treated for gastrointestinal cancers, the effect of surgical treatment on gait kinematics was found.

Lumbopelvic Biomechanics in Patients with Lumbar Disc Herniation—Prospective Cohort Study

“…Our study did not reveal differences in other lumbopelvic parameters in LDH people and healthy controls. This might be due to the young age (18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35) and/or the subacute chronic stage of the disease. Although we did not find differences in other analyzed parameters, the LDH needs further research on gait and lumbopelvic biomechanics.…”

“…Normal values according to the guidelines of the manufacturer, BTS Bioengineering, were given in Table 2. The BTS G-Walk device is based on works based on the correlation coefficient between the mean left and right normalized anteroposterior acceleration signal [25].…”

Walking Speed and Risk of Falling Patients Operated for Selected Malignant Tumors

“…Body posture disorders may result from increased postoperative pain, changes in joint mechanics, and overloading of muscles and tissues. Changing the mechanics of movement in the joints makes it uneconomical and leads to faster tissue wear and the appearance of degenerative changes [11].…”
