Title: Determine the relationship between the valuesof short-term acceleration impulse caused by heel contact with the ground during walking, and osteoarthrosis of knee joint
Abstract:
There are many factors responsible for the development of gonarthrosis. It is suspected that one of such factors is the short-term impulse of the vertical reaction strength component occurring during walking, at the moment of a heel contact with the ground. This impulse is transferred, under the form of acceleration, from the heel, through the whole lower limb, spine, to the skull. The aim of the study was to determine the relationship between the values of short-term acceleration impulse caused by heel contact with the ground during walking, measured at the level of knee joint, and the grade of advancement of radiological degenerative changes and pain complaints in patients suffering from osteoarthrosis of knee joint (gonarthrosis). The aim of the project was achieved based on the studies covering:- a group of 51 subjects of both genders (41 women and 10 men) with gonarthrosis, diagnosed based on criteria of the American College of Rheumatology (ACR),- a control consisting of 30 subjects of both genders (20 women and 10 men) without the diagnosed knee joint arthrosis. Based on the interviews, anthropometric measurements (including determination of BMI index) and assessment of Xray scans of knee joints with gonarthrosis (according to Kellgren-Lawrence grading), the following classification was made:1. Both the group of patients with diagnosed gonarthrosis and the control group ; were divided into:- subjects aged ≤ 65 years and subjects aged >65 years,- subjects with proper body weight, overweight subjects and subjects with obesity.2. The group of patients with diagnosed gonathrosis was divided into sub-groups: - group P 1-2 and L 1-2– subjects with the 1st and 2nd level of advancement of radiological degenerative changes in the knee joint with gonathrosis (P-right, L-left), - group P 3-4 and L 3-4 – subjects with the 3rd and 4th level of advancement of radiological degenerative changes in the knee joint with gonathrosis (P-right, L-left). In all subject studied, the short-term acceleration impulse value was measured at the level of knee joints, as corresponding to the moment of a heel hitting the ground during walking at a natural and maximum speed. In the measurement of acceleration values, two combined accelerometers made according to MEMS technology were used.Directly following the completion of the acceleration measurement, the level of intensity of pain complaints was also assessed in patients with diagnosed gonathrosis (the VAS visual and analogue scale), sensed in the knee joint with gonathrosis. The analysis of the results obtained has shown:1. Lack of significant statistical differences in average values of short-term acceleration impulse caused by a heel contact with the background during walking, both at the natural and at the maximum speed, ; between right knee joints with gonathrosis (in patients from groups: P 1-2, P 3-4), and right knee joints without the diagnosed arthritis (in patients from control group) as well as between left knee joints with gonathrosis (in patients from groups: L 1-2, L 3-4), and left knee joints without the diagnosed arthritis (in patients from control group), among:- subjects aged ≤ 65 years and subjects aged >65 years,- subjects with proper body weight, overweight subjects and subjects with obesity. ; 2. The statistically significant decrease in values of the short-term acceleration impulse caused by heel contact with the ground during walking, both at the natural and at the maximum speed, measured at the level of left knee joints with the 1st and the 2nd advancement grade of radiological degenerative changes, including the major pain complaints in these joints. The results of conducted studies allow for stating the following conclusions:1. No statistically significant differences have been observed between knee joints with gonathrosis and knee joints without the diagnosed arthrosis, in terms of short-term acceleration impulse caused by heel contact with the ground during walking, both at the natural and at the maximum speed, measured at the level of these joints.2. The major pain complaints in the left knee joint suffering from gonathrosis, with the 1st and the 2nd advancement grade o ; f radiological degenerative changes (according to Kellgren-Lawrence grading) is connected with the decreased value of the short-term acceleration impulse caused by a heel contact with the ground during walking, both at the natural and at the maximum speed, measured at the level of this joint.
