Gait symmetry - A valid parameter for pre and post planning for total knee arthroplasty.

Objectives: We aimed to determine whether GS can help to plan and rearrange the treated side by using IMUs to measure the joint angle of the hip, knee, and ankle. We hypothesized that the kinematics in healthy individuals for both sides are approximately equal during walking.

Methods: IMUs were used to measure the joint angles of 25 healthy participants during walking.

Comparison of different symmetry indices for the quantification of dynamic joint angles.

Background: Symmetry is a sign of physiological and healthy movements, as pathologies are often described by increased asymmetries. Nevertheless, based on precisely measured data, even healthy individuals will show small asymmetries in their movements. However, so far there do not exist commonly accepted methods and reference values for gait symmetry in a healthy collective.

Unrestricted stride detection during stair climbing using IMUs.

Stride detection, or the identification of the initial (IC) and terminal contact (TC) of the feet while walking, is important for gait analysis. Automatic stride detection based only on kinematic data is challenging, even when using portable, low-cost, user-friendly Inertial Measurement Units (IMUs). Although there are algorithms for straight walking available, they are often not applicable to other movement patterns.

Effectiveness of total knee arthroplasty rehabilitation programmes: A systematic review and meta-analysis.

Objective: To investigate the effectiveness of modified rehabilitation programmes in comparison with standard rehabilitation programmes after total knee arthroplasty through randomized controlled trials.

Data Sources: A search was conducted in PubMed, PubMed Central (PMC) and Cochrane Library databases in December 2020.

Study Selection: Randomized controlled trials were reviewed if they compared a physiotherapy exercise intervention with usual or standard physiotherapy care, or if they compared 2 types of exercise physiotherapy interventions meeting the review criteria, after total knee arthroplasty for osteoarthritis.
