Effects of Low Intensity Exercise Training during Hemodialysis on Fatigue, Activity of Daily Living, Positive Psychological Capital, and Blood Pressure / 기본간호학회지

PURPOSE: The purpose of this study was to estimate the effects of a video low intensity exercise program provided during hemodialysis on fatigue, activity of daily living, positive psychological capital and blood pressure of patients being treated. METHODS: A non-equivalent control group pre-post test design was used. Participants were 85 hemodialysis patients assigned to either the experimental group (n=41) or the control group (n=44). The experimental group exercised for about 25 minutes 3 times a week for 8 weeks. Data analyses involved descriptive statistics, χ2 test, t-test, multiple regression and repeated measure ANOVA using SPSS/WIN 23.0. RESULTS: The exercise intervention significantly reduced post hemodialysis fatigue and significantly increased positive psychological capital. There was a significant interaction effect on time by group in blood pressure. Systolic blood pressure changes in the experimental group were stable but, changes in the control group tended to increase gradually. CONCLUSION: To reduce fatigue and increase positive psychological capital for hemodialysis patients, providing exercise during hemodialysis is recommended. Furthermore individualized exercise in terms of intensity, time, duration, etc should be developed and tested. Also, to reduce drastic blood pressure changes during hemodialysis, exercise should be provided.

Autologous Bone Marrow Mesenchymal Cell Induced Chondrogenesis for the Treatment of Osteoarthritis of Knee

Healthy and high quality of life has become the main issue with increasing human life span. Many biological treatments for osteoarthritis of the knee have been tried with limited success. We compared data from 7 patients who underwent total knee arthroplasty and 46 patients who underwent autologous bone-marrow mesenchymal cell induced chondrogenesis (MCIC) for osteoarthritis of grade IV of the Kellgren-Lawrence classification and grade IV of modified Outerbridge classification from 50 to 65 years of age. Clinical evaluation of the 2 groups showed significant improvement in the mean telephone Knee Society Scoring system (tKSS)-A (pain) and tKSS-B (function) scores throughout the postoperative follow-up period. There was no difference in the patients' satisfaction between the 2 groups. MCIC is a treatment option at least for delaying disease progression of osteoarthritis of the knee.
