Background. Overweight and obesity are likely to be considered risk factors for osteoarthritis in adult age, with consequences of pain in a lot of districts, such as low back, knee, hip and foot, muscular weakness and limited activities of daily living. Sit-to-Stand (STS) is a typical daily living activity and it can be sperimentally used to monitor pain or illness conditions. Respecting osteoarthritis, musculo-skeletal pain and muscular weakness, STS movement may become difficult in obese patients. Aim of the study is the analysis of the STS movement in healthy and obese subjects, by using a biomechanical model, in order to evidence different biomechanical strategies and postural changes, and to define peculiar rehabilitation programs.
Methods. Ten adult young normal weight subjects (7 female, 3 male; age 26.50±1.64 yrs; BMI 22.20±2.85) and 30 obese patients (25 female, 5 male; age 48.12±11.74; BMI 37.52±4.48) were recruited. A specific motion measurement system, a force platform and a biomechanical model were adapted and studied to analyse kinetic and kinematic data at the low back, at the hip, at the knee and at the foot.
Results. In obese subjects the movement strategy was characterised by a limited trunk flexion and a feet movement backwards from the initial position. Kinetic data are able to confirm high values of the momentum of the knee joint and a reduction of the momentum of the hip joint. Reverse pattern of strategy movement and kinetic data were found in healthy subjects.
Conclusions. During STS, obese subjects use a strategy characterised by a low trunk flexion and a high momentum at the knee joint. This overload condition could be dangerous for degenerative problems, joints and muscular weakness, and poor functional activities of daily living, and it could be important in planning adapted postural re-educational and specific rehabilitative programs.
