Prehabilitation Physical Activity in Persons With Osteoarthritis

Phase 4
Completed
Conditions
Osteoarthritis
Interventions
Other: therapeutical exercises
Registration Number
NCT02881463
Lead Sponsor
University of Tartu
Brief Summary

Knee joint osteoarthritis (OA) reduces functional mobility and performance of daily tasks such as rising from a chair. Therefore interventions aimed at improving muscle strength and sit-to-stand task performance are very important for these patients. The effect of exercise programs, including home exercise programs (HEP), on muscle strength, joint pain and function is well known and widely researched, yet not many studies have investigated the effect of an HEP on electromyographic activity (EMG) of muscles when performing everyday tasks, such as rising from and sitting on a chair. The aim of this study was to investigate effect of prehabilitation in women with severe knee joint OA scheduled for knee joint arthroplasty (TKA).

Primary Outcome Measures
NameTimeMethod
Muscle electromyographic (EMG) activityup to 12 months

Electromyographic (EMG) activity of thigh muscles during gait and sit to stand task (amplitude, mV)

Secondary Outcome Measures
NameTimeMethod
Knee joint pain intensityup to 12 months

Self-reported knee joint pain intensity measured by visual-analogue scale (VAS) (in mm: "0 mm" - no pain and "100 mm" - extreme pain)

Knee joint functionup to 12 months

Self-reported functional status measured by Knee Injury and Osteoarthritis Outcome Score (KOOS) - Symptoms, Pain, Daily Living Activity, Sport and Recreational Activity. Quality of Life. Maximum is 100 points (complains are absent) and minimum is 0 points (extreme complains)

Sit to Stand testup to 12 months

five time Sit to Stand test from standard chair (s)

Mobility testup to 12 months

Timed Up and Go test, 3-m plus return 3-m walking test (s)

Leg muscles strengthup to 12 months

strength of leg extensor muscles (N)

Body balanceup to 12 months

Body postural sway measuring during standing using Kistler force plate (Switzerland) (mm), eyes open and eyes closed

Gait patternup to 12 months

Gait kinematic characteristics measurement using three-dimensional movement analysis system and six optoelectronic cameras (BTS S.p.A. Italy) - joint angles (degrees)
