Abstract
ABSTRACT
Are ground reaction forces and frontal plane knee kinematics during sit-to-stand and stand-to-sit movements related to knee pain and function in people with unilateral knee osteoarthritis? - A pilot study
Keywords
Knee Osteoarthritis, Ground Reaction Force, Varus-Valgus Range Of Motion, Function In ADL, Pain
Background
Movement characteristics and their relationship with individual experience of pain and function have been well documented in patients with knee osteoarthritis (OA) during level-walking. However, little is known about their correlation during other activities of daily living (ADL). Such knowledge can be of interest for the design and evaluation of therapeutical interventions.
Aim
To explore biomechanical... (More)

Background
Movement characteristics and their relationship with individual experience of pain and function have been well documented in patients with knee osteoarthritis (OA) during level-walking. However, little is known about their correlation during other activities of daily living (ADL). Such knowledge can be of interest for the design and evaluation of therapeutical interventions.
Aim
To explore biomechanical measures, in particular ground reaction forces (GRF) and frontal plane knee joint kinematics, during sit-to-stand and stand-to-sit movement. Furthermore, examine their relationship with patients’ subjective experience of pain and function in people with unilateral knee OA.
Design
This cross-sectional study is a preliminary part within a larger project examining biomechanical measures of the knee in various ADL.
Methods
Three-dimensional motion analysis was conducted on 16 patients with unilateral knee OA using a twelve-camera digital optical motion capture system (Vicon MX, Oxford Metrics, UK). Vertical GRF impulse, peak GRF as well as varus-valgus range of motion (VVROM) were calculated as objective variables.
The patients’ experiences of pain level and functionality in ADL were collected with the German version of the KOOS questionnaire.
Pearson’s correlation coefficients were calculated between each variable in order to detect possible interactions.
Ethics
The Ethics Committee of the State Medical Council Baden-Württemberg (Stuttgart, Germany) approved the study. All participants were recruited on a voluntary basis and had to give their written consent to participate in the study.
Results
None of the examined variables differed statistically significant between the affected and the healthy leg.
For the sit-to-stand movement, differences in impulse between the affected and the healthy leg were highly correlated with absolute VVROM of both healthy and affected knee (r= 0.7 resp. r= 0.629) and moderately related to differences in VVROM between the knees (r= 0.447).
In the stand-to-sit movement, only a moderate relation between differences in impulse and absolute VVROM of both healthy and affected knee was identified (r= 0.489 resp. r= 0.405 ).
No correlation between subjective and objective measures could be detected.
Conclusion
Since no correlation between subjective and objective measures could be found, a proposal of therapeutical interventions is not possible based exclusively on these data.
The movements of rising up from a chair or sitting down may be too simple to detect a significant relationship between biomechanical measures and experiences of pain and function in patients with unilateral knee OA. Thus, future research, which evaluates dynamic measures during more complex ADL, is necessary.
Moreover, a distinction that considers the affected knee compartment could be useful to detect specific patterns and relate these to the patient’s experiences.
A healthy control group is necessary in order to verify that measures are specific for patients with OA. (Less)
