“…This is a very efficient model since scores of 1 or 2 in the root node (i.e., the observed impaired balance of the non-dominant or more affected leg in the side-step test) correctly classify 128.4 instances (93.1%) as moderate spastic hemiplegia. Recent research describes similar difficulties for maintaining balance stability, indicating differences in control postural strategies in para-footballers with CP during a one-leg stance position with the dominant [ 59 ] and when comparing both body sides [ 32 ]. Our findings are in line with Reina et al [ 14 ], who demonstrated that the mean velocity of the centre of pressures when performing a one-leg stance is the best predictor for discriminating between different levels of spastic hemiplegia.…”

This study aimed (1) to determine the appropriateness of using decision trees as a classification tool for determining the allocation of sport classes of para-footballers with “moderate vs. mild” cerebral palsy (CP) profiles of spastic diplegia/hemiplegia and ataxia/athetosis based on observational outcomes by international classifiers, and (2) to identify what key observational features were relevant to discriminating among different impairment levels. A sample of 16 experienced international classifiers from five world regions participated in this study, observing activity limitation of a final sample of 21 international CP footballers when performing 16 gross-motor and sports-specific tests for balance (n = 3), coordination (n = 5), running, accelerations and decelerations (n = 3), jumping (n = 4), and change of direction ability (n = 1). For the overall sample (336 observations), the model included eight decision nodes and 24 branches with 17 leaves, including side-step, side-stepping, and triple hop as the tests with the best sensitivity (precision = 67.0%). For those with spastic diplegia (64 observations: Two nodes, six branches with five leaves), the range of motion in the side-step test and the balance in the tandem walk tests correctly classified 89.1% of the observations. In those with athetosis and ataxia (96 observations), the model included five nodes, 15 branches, and 11 leaves (176 observations, precision = 86.5%). For those with spastic hemiplegia, a model containing two nodes, six branches, and five leaves had 90.9% accuracy, including observational features of balance in the side-step test and symmetry in the side-stepping test. The observational tool used in this study, based on the impact of specific impairment measurements of hypertonia, athetosis, and ataxia, can be used to determine which assessments are more appropriate for discriminating between functional profiles in para-footballers with CP.

“…Postural balance is the ability to maintain the center of mass over the base of support under static or dynamic conditions [12]. Postural balance during the unipedal stance is especially important because athletes drive and handle the ball with their feet by consistently using a single limb stance [13]. In soccer, the unipedal postural balance is a fundamental component of performance [14].…”

Background: Balance impairment is a common feature in people with cerebral palsy (CP), affecting the performance of daily-life and physical activities. Objectives: To (1) explore the absolute and relative intrasession reliability of two balance tests to assess dynamic and static balance in ambulant paraathletes with CP; (2) explore the relationships between the two balance tests to determine potential application in sport classification; (3) assess the differences between CP profiles (ie, spastic diplegia, athetosis/ataxia, and spastic hemiplegia) in comparison to those with a minimum impairment; and (4) compare the outcomes of the static and dynamic balance of ambulant para-athletes with CP regarding controls. Methods: A group of 129 male well-trained para-footballers with CP, classified as Level I according to the Gross Motor Function Classification System, participated in the present study. Static balance was assessed using the One-Leg Stance test, performed bilaterally on a force platform, and the dynamic balance was assessed in two conditions of the Tandem Walk test (TW): walking heeltoe contact over a 5 -m straight line and performing 10 steps. Results: Moderate-to-excellent intrasession reliability (intraclass correlation coefficient = 0.60-0.98) was obtained for all the measurements and groups. However, only small to moderate correlations were found between the dynamic and the static measurements of balance for the CP group when performing the One-Leg Stance test with the unimpaired or dominant leg (0.23 < r < 0.30; P < .01). The TW performed over 10 steps revealed more sensitivity to discriminate between CP profiles. Those para-athletes with ataxia/athetosis performed worse in all the tests whereas all CP profiles performed worse than the control group (P < .01). Conclusions: Balance performance and postural control are constrained to a higher extent in those with impaired voluntary control due to ataxia or with involuntary contractions of the muscles due to athetosis.
