AI Article Synopsis

  • A study investigated how preoperative high-intensity strength and balance training affects knee function in patients with end-stage knee osteoarthritis (KOA) after total knee arthroplasty (TKA).
  • Patients were split into an experimental group (receiving the training) and a control group, with various knee function assessments conducted before and after the surgery.
  • Results showed significant improvements in knee strength, balance, and overall function in the experimental group, indicating that this preoperative training can lead to better recovery outcomes post-surgery.

Article Abstract

Background: To investigate the effect of preoperative high-intensity strength training combined with balance training on the knee function of end-stage knee osteoarthritis (KOA) patients after total knee arthroplasty (TKA).

Methods: A prospective study was conducted on end-stage KOA patients awaiting TKA. The patients were divided into an experimental group and a control group according to whether they received a preoperative training intervention. The differences in knee flexor-extensor strength, knee range of motion (ROM), timed up and go (TUG) test result, stair ascend/descend test result, Knee Society score (KSS) and Berg balance scale (BBS) score were assessed in both groups at baseline (T1), before operation (T2), 3 months after operation (T3), and 1 year after operation (T4).

Results: After high-intensity strength training and balance training, the knee flexor-extensor strength, TUG test result, stair ascend/descend test result, and KSS were all significantly improved at T2 in the experimental group over the control group. At T3, the knee ROM, knee flexor-extensor strength, TUG test result, BBS score, and KSS clinical and functional scores were all significantly superior in the experimental group. The experimental group enjoyed a superiority in KSS clinical and functional scores until T4. Group × time and between-group interactions were found in all assessment indicators in both groups (p < 0.01).

Conclusion: Preoperative high-intensity strength training combined with balance training can enhance the knee flexor-extensor strength and balance of patients with end-stage KOA in the short term and help improve early outcomes after KOA. Trial registration ChiCTR2000032857, 2020-05-13.

Making Video Games More Inclusive for People Living With Motor Neuron Disease: Scoping Review.

JMIR Rehabil Assist Technol

December 2024

Background: Evidence suggests that individuals with motor neuron disease (MND), a terminal illness, find enjoyment and social connection through video games. However, MND-related barriers can make gaming challenging, exacerbating feelings of boredom, stress, isolation, and loss of control over daily life.

Objective: We scoped the evidence to describe relevant research and practice regarding what may help reduce difficulties for people with MND when playing video games.

Background: Selective serotonin reuptake inhibitors (SSRIs) are the primary choice for antidepressant therapy in cancer patients with depression. Programmed death-1 and programmed cell death-ligand 1 (PD-1/PD-L1) play a critical role in immune checkpoint inhibitors. To date, there have been no studies reporting adverse events (AEs) associated with the real-world use of PD-1/PD-L1 inhibitors-SSRIs combination.

Anterior Gastropexy for Paraesophageal Hernia Repair: A Randomized Clinical Trial.

JAMA Surg

December 2024

Cleveland Clinic Center for Abdominal Core Health, Department of General Surgery, Digestive Disease and Surgery Institute, The Cleveland Clinic Foundation, Cleveland, Ohio.

Importance: Paraesophageal hernias can cause severe limitations in quality of life and life-threatening complications. Even though minimally invasive paraesophageal hernia repair (MIS-PEHR) is safe and effective, anatomic recurrence rates remain notoriously high. Retrospective data suggest that suturing the stomach to the anterior abdominal wall after repair-an anterior gastropexy-may reduce recurrence, but this adjunct is currently not the standard of care.
