Purpose] The purpose of this study was to examine the factors influencing postoperative physical function using data collected from perioperative patients with gastrointestinal cancer.[Subjects] Subjects were 101 perioperative patients with gastrointestinal cancer.[Methods] Six-minute walking distance (6MWD) was measured to assess postoperative physical function. Subjects were divided two groups based on the 6MWD of greater or less than 400 m. Demographic data (age, gender, cancer stage, surgical site, and body mass index), intraoperative data (surgical time, blood loss, and surgery type), and biochemical data [serum albumin (Alb), prognostic nutritional index, and C-reactive protein] were collected pre and post-operatively.[Results] Multivariate logistic regression, with 6MWD as the dependent variable, identified postoperative Alb as a significantly independent variable in both groups. [Conclusion] We consider postoperative Alb is useful as an indicator of the impact of surgery on physical function of perioperative patients with gastrointestinal cancer.
Patients with cervical spondylotic myelopathy or ossification of the posterior longitudinal ligament have been considered to be prone to falls due to lower extremity dysfunction and gait instability. Anticipatory postural adjustments (APAs) are unconscious muscular activities to counterbalance perturbation. To date, there are no reports on APAs in cervical myelopathy patients, and quantification of postural control remains difficult. Thirty participants were enrolled, of which 15 were cervical myelopathy patients and 15 were normal age- and sex-matched controls. A three-dimensional motion capture system with force plates was used, and the APA phase was defined as the time between start of movement at the center of pressure and heel-off of the step leg. The APA phase (0.47 vs. 0.39 s, p < 0.05) and turning time (2.27 vs. 1.83 s, p < 0.01) were significantly longer, whereas step length tended to be shorter (305.18 vs. 361.04 mm, p = 0.06) in cervical myelopathy patients. There was a significant correlation between Japanese Orthopaedic Association lower extremity motor dysfunction scores and step length (p < 0.01). Cervical myelopathy patients are prone to falls due to longer APA phases with shorter step lengths. Analysis of the APA phase aids the visualization and quantification of postural control during initial gait in cervical myelopathy patients.
Purpose] We investigated changes in perioperative gastrointestinal cancer patients' physical function between before and after surgery, and the influence of gender and surgical procedure on the changes. [Subjects] The subjects were 50 perioperative gastrointestinal cancer patients, 27 males and 23 females with an average of 62.5± 10.7 years, who were categorized by gender and two surgical procedures. [Method] We measured the 6-min walking distance (6MWD) of each patient before and after surgery, and calculated the postoperative distance as a percentage of the preoperative distance (%6MWD).[Results] For all patients, and by gender and surgical procedure, postoperative 6MWD significantly decreased. Further, for %6WMD we found main effects of both gender and surgical procedure.[Conclusion] A significant postoperative decrease in physical function of perioperative gastrointestinal cancer patients was found after surgery, and our results suggest the possibility that gender and surgical procedure are factors influencing the changes in postoperative physical function. We consider that information on gender and surgical procedure of perioperative gastrointestinal cancer patients is important information, because it indicates changes in postoperative physical function.
[Purpose] The purpose of this study was to clarify the relationships between lumbar movement and pelvis, thorax and shoulder range of motion during forward arm elevation by patients with lumbar spinal stenosis.[Subjects and Methods] The subjects were 19 patients with lumbar spinal stenosis. The pelvic, thoracic, and lumbar movements during forward arm elevation, and shoulder range of motion were measured. The relationships between lumbar movement and the other parameters, and between shoulder range of motion and the pelvic and thoracic angles were analyzed.[Results] There were significant relationships between lumbar movement and pelvis angle, thorax angle, shoulder flexion angle, 1st internal rotation and 2nd external rotation, and between thoracic movement and shoulder flexion angle, 1st internal rotation and 2nd external rotation.
