Detailed Description
Objective :
To investigate the effects of core stabilization and sensorimotor exercise program on range of motion, proprioception, balance and functional status in patients with total knee arthroplasty.
Design :
Prospective randomized controlled trial
Subjects :
A total of 36 Ostearthritis patients (69.8 ± 5.1 years) who underwent unilateral knee arthroplasty. Participants were performed TKA surgery by the same physician and followed by the same therapist.
The following inclusion criteria were used: being volunteer, 50-85 age range, being diagnosed with stage 4 OA and undergoing unilateral TKA surgery. The following exclusion criteria were applied: having previous surgery history of affected lower limb, impaired hearing, vision or verbal problems, physical or mental disability, having a neurological or oncologic disease that may affect functional performance.
Patients who met inclusion criteria and were willing to join the study (n=52) were evaluated after being diagnosed with OA and before the operation at the clinic. A total 40 patients undergoing TKA surgery participated in our study and were randomly separated to the Sensorimotor Training Group (SM, n=20) and the Core Stabilization Training Group (CS, n=20). Group allocation was randomized in two blocks of 40 sealed envelopes without external marks, which were mixed and numbered from 1 to 40, containing a piece of paper with the group allocation. All participants were blinded to the treatment type. As a result, 36 patients completed the process.
Outcome Measures :
Patients were assessed on three separate occasions (presurgery, 2 weeks and 8 weeks postsurgery). The primary outcome was proprioception and seconder outcomes were range of motion, Knee Injury and Osteoarthritis Outcome Scale (KOOS), Berg Balance Test, Timed-up & Go test and Sit & Stand -Up tests.
Interventions :
Participants were randomized into two intervention groups: sensorimotor training group (SM, n=17) and Core Stabilization training group (CS, n=19). Both groups were prescribed a 6-week home based exercise programme for 3-5 sessions/week between 2 and 8 weeks postsurgery.

Experimental: Sensorimotor exercise training
SM program included combination of traditional hip and knee exercise, various balance and proprioceptive exercises.
|
The program included side stepping, tandem walking, perturbation exercise, overcoming mini obstacles, walking different surfaces and traditional hip and knee exercise.
Participants applied these exercise as home program between postoperative second weeks and 8th weeks, 3-5 day /week , 20 25 min every session.

Experimental: Core Stabilization exercise training
Core stabilization exercise program contained traditional hip and knee ROM exercise combining the core stabilization as mat activities
|
Core stabilization exercise program was also prepared parallel to the sensorimotor training group intensity; the program contained traditional hip and knee exercise combining the core stabilization as mat activities depending on previous research.core

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Proprioception
Time Frame: change from baseline to postsurgery second weeks , change from postsurgery second weeks to eighth weeks
|
Joint Position Sense(JPS) was assessed to proprioception.
JPS was evaluated via ability to reproduce joint angles using position-matching with active or passive movements (21, 22).
Therapist showed each reference 30 and 60 degree flexion angles passively three times, held it for 10 second and returned to starting position during sitting.
Then, patients were asked to show the target angles with eyes-closed, three deviated angles were recorded and the mean of errors was used for statistics

Measure Description |
Time Frame |
|---|---|---|
|
Range of motion (ROM)
Time Frame: change from baseline to postsurgery second weeks , change from postsurgery second weeks to eighth weeks
|
The ROM of knee and hip joints were assessed bilaterally via a universal goniometer.
|
change from baseline to postsurgery second weeks , change from postsurgery second weeks to eighth weeks
|
|
Sit to Stand Test
Time Frame: change from baseline to postsurgery second weeks , change from postsurgery second weeks to eighth weeks
|
The STS test was applied by recording the elapsed time between the patients who were asked to sit and stand up 5 times as fast as possible
|
change from baseline to postsurgery second weeks , change from postsurgery second weeks to eighth weeks

|
Timed up and Go Test
Time Frame: change from baseline to postsurgery second weeks , change from postsurgery second weeks to eighth weeks
|
In the TUG test, patients were asked to stand up independently from the chair, walk 3 m, turn around and sit at the starting point; the time elapsed between them was recorded (25).
The minimum 2.49 seconds change indicates good clinical properties and below the 14 sec during performance indicate higher risk of falling.

|
Berg Balance Test
Time Frame: change from baseline to postsurgery second weeks , change from postsurgery second weeks to eighth weeks
|
Berg Balance Test was also used to assess the static balance and falling risk of the participants.
The test includes 14 different tasks scored between 0-4 points.
Total scores were recorded between 0-56 points, higher score indicates better balance level
|
change from baseline to postsurgery second weeks , change from postsurgery second weeks to eighth weeks
|
|
KOOS Scale
Time Frame: change from baseline to postsurgery second weeks , change from postsurgery second weeks to eighth weeks
|
KOOS consists of 42 items and five subscales: pain, symptom, activities of daily life, quality of life, sport and recreation.
All questions are scored 0-4 points and subscales points are converted separately to 0-100 points.
Higher point indicates no knee problems

Tampa Scale of Kinesiophobia
Time Frame: change from baseline to postsurgery second weeks , change from postsurgery second weeks to eighth weeks
|
Consist of 17 items, evaluate the fear of movement.
|
change from baseline to postsurgery second weeks , change from postsurgery second weeks to eighth weeks

Oswestry Low Back Disability Questionnaire
Time Frame: change from baseline to postsurgery second weeks , change from postsurgery second weeks to eighth weeks
|
The Oswestry Disability Index is an index derived from the Oswestry Low Back Pain Questionnaire used by clinicians and researchers to quantify disability for low back pain.
