“…There is little research to date exploring the functional joint kinematics required to rise from the floor. Most studies investigating joint kinematics in older adults utilize walking, jumping, squatting and stair walking as activities [ 29 , 30 , 31 , 32 , 33 , 34 ]. However, two studies have looked at activities of daily living (ADLs) of older adults [ 35 , 36 ].…”

A third of older adults will fall each year and many will not be injured. Getting up from the floor in a timely manner is important, however it is unclear what technique older adults use to get themselves up off the ground unassisted, whether there are differences between men and women in getting up and what functional joint kinematics are used to rise from the floor. This study included a convenience sample of 20 older adults (65+ years) to answer these questions. Participants completed a series of movement tasks (i.e., rising from the floor using their own technique, a specified technique, walking 10 m and five repeated sit-to-stands), with temporospatial and joint kinematic data captured using an 18-camera 3D Vicon motion analysis system. Results found three techniques preferred by participants; the sit-up (n = 12), side-sit (n = 4) and the roll over (n = 4), with no differences found between sexes. The sit-up technique requires a higher degree of hip and knee flexion to complete compared to the side-sit and roll over. It may be beneficial for health professionals to work with older adults to identify their preferred technique for rising from the floor and encourage regular practice of this skill.

Obstacle Crossing in Older Adults with Total Knee Arthroplasty at the Initial Swing Phase

2022

After undergoing a total knee arthroplasty (TKA) procedure, patients are at a high risk of falling because they present with ineffective mobility within a complex environment, especially during obstacle crossing. Toe clearance (TC) is an important factor to quantify the risks of trip-related falls. The study aimed to investigate TC height and toe trajectory and joint kinematic changes occurring in the lower limb following TKA during obstacle crossing at the initial swing phase. Twenty TKA patients, including those in preoperative and postoperative stages (three and six months), performed obstacle-crossing tasks to compare their performance with 20 healthy controls. Participants walked at self-pace along an 8 m walkway with 2.5, 5, and 10 cm obstacles positioned along the center of the path. For each participant, body segment motions were traced using reflective markers and the kinematics of lower extremity, toe clearance, and gait parameters were analyzed using a 3D-motion analysis system. TKA patients had lower TC height and toe trajectory at six months, slower toe elevation than controls when swing toe crossed 5 and 10 cm obstacles (p < 0.05), and decreased hip and knee flexion (p < 0.05). These altered gait patterns with decreased TC height and toe trajectory were identified as tripping factors as the toe trajectory was close to the ground surface. TKA patients had acquired different lower limb kinematics to maintain adequate TC. At long-term follow-up, there was an increasing trend for patients to trip after surgery. Therefore, more focus is needed on the exercise prescription for rehabilitation programs to improve muscle strength and stepping control.

(1) Background: Total knee arthroplasty (TKA) performed on working-age patients significantly affects the participation of such patients in social life. A retrospective study was conducted to determine the return to work (RTW) rate after TKA. The goal of this study was to provide reference data for the Polish population and identify the factors impacting patients’ decisions to return to or resign from work, relative to their functional performance. (2) Methods: This retrospective study involved 48 patients. An interview related to RTW was carried out to identify the factors impacting a patient’s decision to return to or resign from work. Functional performance was assessed using the Knee Outcome Survey–Activities of Daily Living (KOS-ADL) scale. (3) Results: Before TKA, 15 individuals (31.25%) qualified for the study did not work and were receiving welfare benefits. After the surgery, 23 individuals (47.9% of those working prior to TKA) did not return to work. The number of those who did not work after TKA increased to 38 (79.17%), which was a significant change. The mean level of functional performance after TKA assessed using KOS-ADL was 75.89. (4) Conclusions: The findings show that the rate of RTW after TKA in Poland is significantly lower than that in other countries. The reasons for this situation, as shown in the study, may be related to the lack of an occupational rehabilitation system, resulting in a paucity of information about the possibility to return to work and about opportunities for retraining.
