Abstract
Background. Scoliosis is defined as a multi-dimensional deformity of the spine frequently associated with a compensatory spinal curvature and changes in pelvic and lower limb alignment. Changes in the spatial arrangement of the foot joints may affect coordination of movement patterns, muscle balance and static and dynamic proprioceptive control. The aim of this study was to assess dynamic and static postural control in children with scoliosis and different longitudinal foot arch patterns. Material and methods. The study involved 69 children aged 5 to 18 years with scoliosis confirmed by an orthopaedist. The patients were treated at orthopaedic outpatients clinics and had not undergone previous operative treatment. Longitudinal foot arch parameters were assessed with a Podoskop (Posmed, Poland) device and the Wejsflog index.. Static and dynamic postural control was assessed with a CQStab2P Stabilometric Platform (two-platform version, CQ Elektronik System, Poland) and the Delos Postural System (Delos s.r.l., Italy). Results. In the children with reduced functional efficiency of the feet, the sway path and the sway area were higher during stabilometric measurements with eyes closed. Mean postural priority among persons with inefficient feet did not exceed 60%. Conclusions. Preliminary results indicate the presence of disturbances of balance and proprioception among children with scoliosis and reduced or poor functional efficiency of the feet.

Abstract
This paper presents the results of comparative bilateral global surface electromyography (gEMG) recordings from selected upper and lower extremity muscles in patients undergoing rehabilitation following spinal cord injuries at C4-Th8 levels. It was assumed that this technique can enable precise monitoring of changes in muscle tone during treatment in patients with spinal injuries.Surface gEMG recordings were obtained at rest (complete muscle relaxation) and during maximum muscle contraction in 12 patients (aged from 21 to 45 years) from the anterior tibial muscle, gastrocnemius muscle and abductor pollicis brevis muscle before and after four weeks of rehabilitation.Signs of increased muscle tone during surface gEMG recordings at rest observed in the patients were associated with elevated amplitude (mean 52μV). This parameter decreased to a mean of 37μV following rehabilitation. The observed decrease in muscle tone was accompanied by an increase in mean gEMG amplitude of the muscles during their maximum effort.Surface gEMG recordings are a precise diagnostic tool serving to evaluate not only muscle performance during maximum effort but also muscle tone at rest.
