The kinetics and kinematics of the knee joint during a variety of activities of daily living were studied in a group of total knee replacement (TKR) patients. The parameters examined were those needed to program a force-controlled knee simulator (axial and anterior-posterior (AP) forces, internal-external (IE) moment, and flexion angle). These parameters were calculated for walking, fast walking, stand-to-sit, sit-to-stand, bending, stair ascent and stair descent using body-fixed inertial sensors, a force platform, and estimates of muscles forces. Peak values for loading patterns were not significantly different from those for an age-matched control group. Axial forces were lower in comparison to published results for normal and TKR populations, due to slower cadences and conservative estimates of muscle forces. Peak posterior forces and IE moments were higher than published results. These patterns were combined to form a spectrum loading pattern, with the activities occurring in approximately the same ratios of relative frequency as reported in the literature. The spectrum pattern can be used to program a force-controlled knee simulator in order to apply more relevant loading patterns to knee implants.

Background: Barriers to performing activities of daily living are common complaints of patients with cancer. One of the factors causing these barriers is pain. A modified pro-self pain control is a method used to enhance the patients’ ability to cope with pain to increase their activity.Purpose: This study aimed to evaluate the modified pro-self pain control to increase activity in patients with colorectal cancer undergoing chemotherapy.Methods: The present study employed an experimental design. Patients with colorectal cancer undergoing chemotherapy were randomly assigned to the intervention group (n=24) and the control group (n=24). The patients in the control group were given a standard hospital intervention, while the patients in the intervention group were given the modified pro-self pain control for nine days. The data were collected using the instrument of KATZ index and analyzed using the independent t-test.Results: The result of this study showed that there was a higher increase of activity among the patients in the intervention group than in the control group. Independent t-test showed that there was a significant difference between the intervention group and the control group (p=0.00).Conclusion: The modified pro-self pain control was found more effective to increase the activity in patients with colorectal cancer undergoing chemotherapy than that of the standard hospital intervention.

Background: Frailty is a status of extreme vulnerability to endogenous and exogenous stressors exposing the individual to a higher risk of negative health-related outcomes. Exercise using interactive videos, known as exergames, is being increasingly used to increase physical activity by improving health and the physical function in elderly adults. The purpose of this study is to ascertain the reduction in the degree of frailty, the degree of independence in activities of daily living, the perception of one’s state of health, safety and cardiac healthiness by the exercise done using FRED over a 6-week period in elderly day care centre. Material and Methods: Frail volunteers >65 years of age, with a score of <10 points (SPPB), took part in the study. A study group and a control group of 20 participants respectively were obtained. Following randomisation, the study group (20) took part in 18 sessions in total over 6 months, and biofeedback was recorded in each session. Results: After 6 weeks, 100% of patients from the control group continued evidencing frailty risk, whereas only 5% of patients from the study group did so, with p < 0.001 statistical significance. In the case of the EQ-VAS, the control group worsened (−12.63 points) whereas the study group improved (12.05 points). The Barthel Index showed an improvement in the study group after 6 weeks, with statistically significant evidence and a value of p < 0.003906. Safety compliance with the physical activity exceeded 87% and even improved as the days went by. Discussion: Our results stand out from those obtained by other authors in that FRED is an ad hoc-designed exergame, significantly reduced the presence and severity of frailty in a sample of sedentary elders, thus potentially modifying their risk profile. It in turn improves the degree of independence in activities of daily living and the perception of one’s state of health, proving to be a safe and cardiac healthy exercise. Conclusions: The study undertaken confirms the fact that the FRED game proves to be a valid technological solution for reducing frailty risk. Based on the study conducted, the exergame may be considered an effective, safe and entertaining alternative.

Group Reminiscence

The current study aimed to investigate the effects of group reminiscence therapy on cognitive function, depression, neuropsychiatric symptoms, and activities of daily living in patients with mild-to-moderate Alzheimer disease (AD). A single-blind randomized parallel-design controlled trial was conducted between May 1, 2017, and April 30, 2018. Ninety patients with mild-to-moderate AD recruited from Beijing Geriatric Hospital were randomly allocated into intervention (n = 45) and control groups (n = 45). In the intervention group, group-based reminiscence therapy was performed in two 30- to 45-minute sessions weekly for 12 weeks. Control participants received only conventional drug treatments and routine daily care. Alzheimer disease–related symptoms were evaluated using the Alzheimer’s Disease Assessment Scale-Cognitive section, the Cornell Scale for Depression in Dementia (CSDD), the Neuropsychiatric Inventory, and the Barthel Index. Four time points were set for data collection: baseline (before treatment), 4 weeks (during treatment), 12 weeks (end of treatment), and 24 weeks (12 weeks posttreatment). χ2 Tests, independent t tests, repeated-measures analysis of variance, and Bonferroni tests were used for data analysis. Significant improvements in depressive and neuropsychiatric symptoms were found in the intervention group compared to the control group ( P < .05). Mean CSDD scores in the intervention group were improved at all 3 time points compared to baseline and showed the greatest effect at 12 weeks ( t = 2.076, P = .041) and 24 weeks follow-up ( t = 3.834, P = .000) compared to controls. Group reminiscence therapy was effective for improving depressive symptoms and was beneficial for treating neuropsychiatric symptoms in patients with AD.

AbstractThis study intends to explore the effects of tranexamic acid (TA) on occult blood loss, blood transfusion, and recovery of knee function in patients undergoing total knee arthroplasty (TKA). From October 2013 to April 2015, 224 patients undergoing TKA were enrolled in this study. These patients were randomly assigned into the control group (intravenous infusion of normal saline), 10 mg/kg TA group (intravenous infusion of 10 mg/kg TA) and 15 mg/kg TA group (intravenous infusion of 15 mg/kg TA). Compared with the control group, the 10 and 15 mg/kg TA groups were lower in postoperative blood loss, occult blood loss, blood transfusion rate, and volume. In comparison to the control group, hemoglobin levels were lower and the number of red blood cells was higher at 7 days after surgery in the 10 and 15 mg/kg TA groups. Higher fibrinogen levels and lower prothrombin time (PT), activated partial thromboplastin time, D-dimer levels, thrombin time, lower the visual analog scale/score, and circumference diameter of knee joint were observed in the 10 and 15 mg/kg TA groups compared with the control group at 7 and 14 days after surgery. At 1 and 3 months after surgery, the knee joint range of motion scores, Hospital for Special Surgery scores, and Knee Society Score were increased in 10 and 15 mg/kg TA groups in comparison to the control group. TA could reduce occult blood loss and blood transfusion rate and improve recovery of knee function in patients undergoing TKA.

Abstract Background To examine the effects of a 6-month multicomponent (MT) exercise intervention in the functional capacity and ability to independently perform activities of daily living (ADL) of individuals diagnosed with neurocognitive disorder (NCD). Methods A quasi-experimental controlled trial with a parallel design study was conducted in multicentered community-based settings. Forty-three individuals (N Female: 30) were allocated to an exercise group (EG; N: 23; mean 75.09, SD = 5.54 years) or a control group (CG; N:20; mean 81.90, SD = 1.33 years). The EG engaged in a 6-month MT program (60-min sessions, twice a week). Exercise sessions were divided into a warm-up, specific training (e.g., coordination and balance, lower and upper body strength, and aerobics), and cool down. Lower body function, mobility, and gait speed were evaluated through Short Physical Performance Battery (SPPB), Timed-Up and Go test (TUG) and 6-Meter Walk test, respectively. The Barthel Index (BI) was administered to assess individuals’ ADL independence. Evaluations were performed before and after the 6-month intervention. Results Linear Mixed Models revealed a statistically significant interaction (time X group) effect factor on SPPB (B = 2.33, 95% CI: 1.39–3.28, p < 0.001), TUG (B = − 11.15, 95% CI: − 17.23 – − 5.06, p = 0.001), and 6-Meter Walk test (B = 0.17, 95% CI: 0.08–0.25, p < 0.001). No differences between groups or assessment moments were found in the ability of individuals to independently perform ADL. Conclusions The 6-month MT exercise intervention improves the functional capacity of older adults living with NCD. Trial registration ClinicalTrials.gov – identifier number NCT04095962; retrospectively registered on 19 September 2019.
