Opis:
Purpose: One of the aims of the treatment in ambulant cerebral palsy (CP) patients is improvement of gait. Level of gait pathology is assessed by instrumented gait analysis, including surface electromyography. The aim of this study was to investigate the relation of the abnormality level of the gait and the co-contraction of the agonist-antagonist muscles, and relation between symmetry left /right leg in gait and symmetry of muscular activity. Methods: Fifty one patients with Cerebral Palsy underwent clinical assessment and instrumented gait analysis, including surface electromyography. Signals were bilaterally collected from rectus femoris, medial and lateral hamstrings, tibialis anterior, lateral gastrocnemius and gluteus maximus. In older children additionally signals from soleus and lateral vastus were recorded. Sixteen gait variables were selected to calculate Gillette Gait Index, separately for left and right leg. From the envelopes the series of cross-correlation coefficients were calculated. Results: Weak correlations were found between averaged agonist-antagonist correlation coefficient and Gillette Gait Index. Differences between hemiparetic less-involved legs, hemiparetic spastic legs, and diplegic legs were found for co-contraction of rectus femoris and biceps femoris and for averaged agonist-antagonist co-contraction. The differences between hemiparetic and diplegic groups were found for some muscle correlation coefficients. Conclusions: The results obtained in this study show, that the activity pattern of the leg muscles is specific for a given patient, and the dependence of the kinematics pathology on the abnormal activation pattern is not a direct one.

Opis:
The functional gait problems encountered by stroke patients include impaired balance, abnormal gait pattern with marked asymmetry, pathological trunk and spinal motion. Many different methods of physiotherapy are used to improve functional ability (especially gait) in stroke patients, but their efficacy and outcome are often not objectively assessed. The goal of this paper is to compare two therapeutic programs: one that is traditionally used in our rehabilitation facilities (exercises in lying position, “open chain” exercises, isolated movements of extremities with trunk stabilization) and the new one (exercises in vertical position, sitting or standing, “closed chain” exercises involving whole paretic side of the body). Fifty one stroke patients, aged 34 to 79 years, participated in the study. Patients were randomly allocated to one of the two groups. Patients underwent clinical assessment (Fugl-Meyer, Rivermead Motor Assessment, Berg Balance Scale) and instrumented gait analysis (using six-camera VICON 460 system) simultaneously three times: prior to the beginning of the rehabilitation program, after 6 weeks of the program, and after another 6 weeks of physiotherapy, at the end of rehabilitation program. Results demonstrated that both rehabilitation programs improved the gait function and clinical status in patients suffering from stroke. Despite the differences between the two programs the progress achieved by the patients in locomotor function is similar. Two equivalent physiotherapy programs could be applied during rehabilitation process depending on the patient’s individual preferences and needs, as the amount of functional improvement provided by them is comparable.
