The purpose of this study was to determine which stratification (anatomical versus functional) forms a better construct for classification of para surfers with spinal cord injury; to assess the groupings of these para surfers; and to evaluate the strength of association between manual muscle testing and surfing performance.
Cross-sectional.
Archived data from classification records including demographics, spinal cord injury levels, trunk strength, and limb strength were compared to judged wave scores and competition rankings.
Participants (n = 70, male n = 56; female n = 14) met inclusion criteria and were classified into Para Surfing Kneeling (n = 9); Sit (n = 11); Prone 1 (n = 25); and Prone 2 (n = 25) sport classes. Reliability statistics showed that functional grouping (Cronbach's α = 0.759) is better grouped with strength testing and rankings compared to anatomical grouping (Cronbach's α = 0.721). Under exploratory factor analysis with 2 fixed components, based on the factor loadings (rank and strength) functional stratification (0.978) is better aligned compared to anatomical stratification (0.785) for grouping of surfers. Further, the association and impact of strength with functional spinal cord level stratification were confirmed using regression analysis (chi-square of 74.06 with p-value <.0001).
Trunk and limb strengths have been shown to influence wave riding performance in surfers with spinal cord injury. Surfers with spinal cord injury can equitably be classified into one of the four para surfing sport classes. The use of functional stratification of spinal cord injury with trunk and limb strengths should be considered as an integral component in para surfing athlete sport classification.
本研究旨在确定哪种分层方式（解剖学分层与功能分层）能更好地构建脊髓损伤残疾冲浪运动员的分类体系；评估这些残疾冲浪运动员的分组情况；并评估徒手肌力测试与冲浪表现之间的关联强度。
横断面研究。
将分类记录中的存档数据（包括人口统计学数据、脊髓损伤水平、躯干力量和肢体力量）与评判的波浪分数和比赛排名进行比较。
参与者（n = 70，男性n = 56；女性n = 14）符合纳入标准，被分为残疾冲浪跪姿组（n = 9）；坐姿组（n = 11）；俯卧1组（n = 25）；和俯卧2组（n = 25）运动类别。可靠性统计显示，与解剖学分组（Cronbach's α = 0.721）相比，功能分组（Cronbach's α = 0.759）在与力量测试和排名的分组上表现更好。在具有2个固定成分的探索性因素分析中，基于因素载荷（排名和力量），功能分层（0.978）在残疾冲浪运动员分组方面比解剖学分层（0.785）更匹配。此外，使用回归分析（卡方值为74.06，p值 <.0001）证实了力量与功能性脊髓水平分层之间的关联和影响。
已证明躯干和肢体力量会影响脊髓损伤残疾冲浪运动员的冲浪表现。脊髓损伤残疾冲浪运动员可公平地分为四个残疾冲浪运动类别之一。应考虑将脊髓损伤的功能分层与躯干和肢体力量作为残疾冲浪运动员运动分类的一个组成部分。
