OBJECTIVES To evaluate the limits of stability (LOS) in persons with transtibial amputation (TTA), and to determine the effects of prosthetic alignment alterations on motor control strategies. DESIGN Before-and-after trial. SETTING A kinesiology laboratory at a university hospital. PARTICIPANTS Male patients with TTA (n=10) and controls (n=17). (More)
OBJECTIVE The aims of this study were: (i) to monitor changes in central facial paresis in patients with stroke after orofacial therapy, using functional scales and video analysis of the face; and (ii) to investigate correlations between changes in facial movement and mental function of patients after stroke. METHODS A prospective blind randomized study(More)
Individual indices of spectral analysis (SA) of heart rate variability (HRV), which are used to diagnose the autonomic nervous system (ANS) activity, often give somewhat inconclusive and antagonistic results. Based on the results of age dependence (Šlachta et al., 2002), and dependence of exercise intensity (Stejskal et al., 2001) on the short-term SA HRV,(More)
The morphologic variations of the shoulder blade have not yet been evaluated in clinical medicine. We observed that subjects with less standard shapes of the shoulder blade often suffer from musculo-skeletal shoulder syndromes with concurrent intrinsic impingement syndromes or, more precisely, partial-thickness rotator cuff tears. This experience became a(More)
Hippotherapy employs locomotion impulses that are emitted from the back of a horse while the horse is walking. These impulses stimulate the rider's postural reflex mechanisms, resulting in training of balance and coordination. The aim of the present study was to assess the changes in magnitude and distribution of the contact pressure between the rider and(More)
Take-off and transition phase were compared with the use of 2D videography by the competitors in ski-jumping and Nordic combined. The basic material was recorded at the events World Cup Liberec’99 and Championship of the Czech Republic. The quality of the motor abilities that are necessary for the performance was measured in the biomechanical laboratory(More)
Between 1992 and 2010, a total of 334 males participated in this study that assessed the differences and relationships between anthropometric variables and lower limb muscle strength in young and adult ski jumpers (n = 207) and Nordic combined (NC, n = 127) athletes. All athletes completed a maximal vertical jump from an in-run position and a maximal(More)
Spectral analysis (SA) of heart rate variability (HRV) is generally accepted to be a valid, noninvasive suitable method for evaluation of the autonomic nervous system (ANS) activity. Since advancing age in healthy subjects is related with deterioration in communication between the nervous and the cardiovascular systems (Xaio & Lakatta, 1991), HRV is known(More)
BACKGROUND Prosthetic gait increases demands on stability. Some variability measures can be used to investigate the stability of movement for prosthetic feet. OBJECTIVES The purpose of this study was to determine the influence of the prosthetic foot on ground reaction force variability for transtibial amputee gait. STUDY DESIGN Comparative analysis. (More)
A new approach in the evaluation of heart rate variability (HRV) is suggested by virtue of factor analysis, analysis of variance and correlation coefficients between parameters of spectral analysis (SA) heart rate variability and age. The reduced number of parameters were divided into three groups: age-dependent (increasing with age), age-dependent(More)
