About

Objective: To investigate the effects of core stability exercises (CSE) added to the standard exercises (SE) on patient-reported (PR) and performance-based (PB) outcomes in patients with total knee arthroplasty (TKA) followed with telerehabilitation (TR).

Methods: The 42 patients who participated in the study were randomly divided into 2 groups [group 1: SE (n= 21), group 2: SE + CSE (n= 21)]. The first 8 weeks of the post-discharge follow-up were performed by videoconference-based TR under the supervision of a physiotherapist and the last 4 weeks by telephone-based TR. Functional level was assessed by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), pain intensity by Visual Analog Scale (VAS), affected knee range of motion (ROM) by Copenhagen Knee Range of Motion Scale (CKRS), quality of life by Short Form-12 (SF-12) and World Health Organization Quality of Life Scale Brief Version (WHOQOL-BREF), lower extremity muscle strength by 30-seconds Chair-Stand Test and locomotor performance by Stair Climb Test. Assessments were performed with TR preoperatively and at the first, second and third post-op months.

Full description

At the beginning of the study, an exercise booklet and exercise videos were prepared to be followed throughout the follow-up period. Subsequently, a telerehabilitation (TR) system was established using a laptop computer, a smartphone and a camera as hardware and WhatsApp® and Zoom® applications as software. The surgeries of all patients participating in the study were performed by the same surgical team with fast-track surgical procedure. Until discharge (1 day), a standard physiotherapy and rehabilitation (PTR) program consisting of range of motion and strengthening exercises, cold application, weight transfer and walking training was applied to both groups of patients. At the time of discharge, each patient was given an exercise booklet according to the intervention group.

During the follow-up period, only the interventions included in the standard exercise (SE) program were applied to the SE group, while interventions included in both the SE and core stability exercise (CSE) program were applied to the SE + CSE group. In addition to the TR sessions, each patient performed the interventions belonging to the group they were included in as a home program (HP), 3 sessions per day for the first 8 weeks of the follow-up period. Patient follow-up, which started from the 1st week after discharge, continued for 12 weeks. The content of the follow-up process was planned to include information, assessment, and PTR interventions. The first 8 weeks of the follow-up period consisted of PTR sessions performed with video-conference-based TR method under the supervision of a physiotherapist and HP, while the last 4 weeks consisted of the follow-up of the walking program performed with telephone-based TR method.
