The Benefit of Functional Movement Control for Patients With Knee Osteoarthritis

Overview

The study purpose is to explore the effect of functional movement control for patients who have stage II or III degenerative knee joint disease and also physical inactive. Half of patients will receive aerobic exercise and functional movement control training in combination, while the other will simply receive aerobic exercise.

Detailed Description

Physical inactivity, which is a common phenomenon among patients with degenerative knee joint disease has been proved a predictor of increased symptoms and poor general health. However, changing the lifestyle of people with this disease who is physical inactive is still a problem which has not been solved. Knee pain may act as barrier to engage in physical activity and can influence patient's movement performance. The different effectiveness between the aerobic exercise and functional movement control training. Aerobic exercise has been proved could improve knee pain for the patients with degenerative knee joint disease. The functional movement control training could improve knee alignment during walking and other functional activities to increase patient's movement awareness.

Interventions

  • Behavioral: Aerobic exercise & movement control
    • The aerobic exercise content is no different between the experimental group and the active comparator group. The movement control is individual training which divided into fourths progressing sessions. First, lumbo-pelvic and hip dynamic direction control. Second, trunk muscle groups, hip muscle groups and thigh muscle groups extensibility control. Third, trunk muscle groups and hip muscle groups through range control. Fourth, functional movement control training
  • Behavioral: Aerobic exercise
    • The aerobic exercise will organized in groups. Each group has 6-8 persons. The exercise form is fixed at each time. The description of exercise form is as below: 10 min Warm up 40 min Aerobic exercise (which focus on lower extremity muscle strengthening and increasing muscle endurance) 10 min Cool down

Arms, Groups and Cohorts

  • Experimental: Aerobic exercise & movement control
    • The duration of intervention is 8 weeks. Individualized functional movement control training is 60 min/week Aerobic exercise is 60 min/week
  • Active Comparator: Aerobic exercise
    • The duration of intervention is 8 weeks. Frequency: 2 times/ week Duration: 60min/ time

Clinical Trial Outcome Measures

Primary Measures

  • reaching proportions of the level of health enhancing physical activity
    • Time Frame: up to 6 months after intervention
    • the recommended level of health enhancing physical activity is at least 150 min of moderate intensity physical activity per week

Secondary Measures

  • Partial foot pressure as a percentage of body weight
    • Time Frame: Baseline and up to 1 week after intervention
    • The area footprinted during gait was divided into 6 parts according to the average foot areas of subject. Then, the partial foot pressure as a percentage of body weight was calculated as the average value during the stance phase of each step in each part as a percentage of the body weight.
  • Partial foot area as a percentage of body mass index
    • Time Frame: Baseline and up to 1 week after intervention
    • The area footprinted during gait was divided into 6 parts. The partial foot area as a percentage of body mass index was calculated as the average value during the stance phase of each step in each part as a percentage of the body mass index.
  • Gait Cadence
    • Time Frame: Baseline and up to 1 week after intervention
    • the number of steps per minute
  • Walking speed
    • Time Frame: Baseline and up to 1 week after intervention
    • the velocity of single step
  • Single leg stance time
    • Time Frame: Baseline and up to 1 week after intervention
    • the time of the stance phase of each foot
  • Step length
    • Time Frame: Baseline and up to 1 week after intervention
    • the distance between the first point of contact of a limb with the ground and the first point of contact of the limb on the opposite side
  • Step width
    • Time Frame: Baseline and up to 1 week after intervention
    • the distance between the centre of the first heel contact and the following one calculated perpendicularly to the direction of the horizontal axis drawn between the feet
  • Axis angle
    • Time Frame: Baseline and up to 1 week after intervention
    • the angle formed by the medial tangent of the foot and the line from the second/third toe to the center of the heel
  • The Knee injury and Osteoarthritis Outcome Score
    • Time Frame: Baseline and up to 1 week after intervention
    • A questionnaire to assess the patient’s opinion about their knee and associated problems.
  • Sort Form-12v2 Healthy Survey
    • Time Frame: Baseline and 1, 3, 6 month after intervention
    • 12 question to measure functional health and well-being from the patient’s point of view
