Previous literature has theorized that alterations in shoulder physical characteristics are present in wheelchair athletes and contribute to shoulder pain and injury. Limited empirical evidence is present that evaluates the effectiveness of a shoulder injury prevention program focusing on improving these altered characteristics.
To evaluate the effectiveness of a 6-week intervention program at improving characteristics that increases the risk of developing pain or shoulder injury.
Pretest and posttest.
Home-based and controlled laboratory.
Seven college wheelchair athletes.
Shoulder range of motion (ROM) and scapular muscle strength were assessed, and a 5-minute injury prevention program was taught to participants. Participants completed the intervention 3 times per week for 6 weeks. Following completion of the program, a postintervention screening was performed.
Internal rotation (IR)/external rotation (ER) ROM, retraction strength, and IR/ER strength.
Participants experienced a significant improvement in dominant limb shoulder IR ROM (t = 3.56, P = .01) with an average increase of 11.4° of IR ROM and a significant improvement in dominant limb shoulder ER ROM (t = 2.79, P = .03) with an average increase of 8.0° of ER ROM. There were no significant increases in shoulder IR or ER strength and scapular retraction strength (P > .05).
Improvements in ROM have previously been linked to decreases in shoulder pain and injury in other upper-extremity dominant sports by improving scapular kinematics. These results provide evidence that a 6-week strengthening and stretching intervention program may decrease risk factors for shoulder injury in wheelchair basketball athletes.
以往文献推测,轮椅运动员存在肩部生理特征改变,这会导致肩部疼痛和损伤。但评估针对改善这些改变特征的肩部损伤预防计划有效性的实证证据有限。
评估一项为期6周的干预计划在改善增加疼痛或肩部损伤风险特征方面的有效性。
前测和后测。
居家和受控实验室。
7名大学轮椅运动员。
评估肩部活动范围(ROM)和肩胛肌力量,并向参与者教授一个5分钟的损伤预防计划。参与者每周完成3次干预,共6周。计划完成后,进行干预后筛查。
内旋(IR)/外旋(ER)ROM、后缩力量以及IR/ER力量。
参与者优势侧肩部IR ROM有显著改善(t = 3.56,P = 0.01),IR ROM平均增加11.4°;优势侧肩部ER ROM也有显著改善(t = 2.79,P = 0.03),ER ROM平均增加8.0°。肩部IR或ER力量以及肩胛后缩力量无显著增加(P > 0.05)。
此前在其他上肢主导运动中,ROM的改善通过改善肩胛运动学与肩部疼痛和损伤的减少相关。这些结果提供了证据,表明为期6周的强化和拉伸干预计划可能会降低轮椅篮球运动员肩部损伤的风险因素。
