摘要

目的：探討視力屈光異常運動員經適當屈光調節前後對頭頸部肌肉緊張情形的影響。方法：由合格的眼科醫師檢查評估後，以有屈光異常的大學運動員15人為受試者，進行屈光調節前後的測量，受測項目包含上斜方肌激痛點之肌肉緊張程度及壓痛自覺水準、上斜方肌激痛點及眼眶肌群激痛點之壓痛閾值。結果：一、屈光異常情形以過度調節、散光及散光軸度的比例較高；二、屈光調節前後的上斜方肌肌張力評估之肌肉張力、肌肉彈性、肌肉硬度、肌肉放鬆時間及肌肉黏滯性等均未達顯著差異；但在屈光調節後的肌肉張力、肌肉彈性、肌肉硬度等有小幅度的改善；三、屈光調節後的上斜方肌壓痛閾值、眼眶肌群壓痛閾值及視覺類比量表（visual analogue scale, VAS）壓痛自覺均顯著優於調節前；四、各種屈光異常情形皆與肌肉張力、肌肉彈性、肌肉硬度、肌肉放鬆時間、肌肉黏滯性、上斜方肌壓痛閾值、眼眶肌群壓痛閾值、VAS壓痛自覺等未達顯著相關。結論：屈光異常運動員經適度屈光調節後，可提升頸後上斜方肌及眼眶肌群的壓痛閾值，並降低上斜方肌壓痛自覺水準，且肌肉緊張程度有獲得改善。

Purpose: To investigate the effect of refractive error to accommodation on head and neck muscle tension for athletes. Methods: After examination and evaluation by ophthalmologists, 15 college athletes of participants were measured on pre and post accommodation. The measured included the tension and the visual analogue scale (VAS) of tenderness level on the upper trapezius muscle trigger point, and tenderness threshold on trigger point of the upper trapezius muscle and the orbicularis oculi muscle orbital part. Results: (1) The refractive error on over-accommodative, astigmatism and astigmatism axis had a higher proportion. (2) There were no significant difference between pre and post accommodation on the upper trapezius muscle tension, but the tone, elasticity, and stiffness had improve on after accommodation. (3) The tenderness threshold of the upper trapezius muscle, the orbicularis oculi muscle and VAS of tenderness level were significantly better than pre accommodation. (4) There were no significant correlation between the refractive error to accommodation (myopia, hyperopia, and astigmatism) and the tenderness threshold of the upper trapezius muscle tension, the orbicularis oculi muscle, and VAS of tenderness. Conclusion: After refractive accommodation for athletes, it improved the tenderness threshold of the upper trapezius muscle and the orbicularis oculi muscle, and reduced the level of tenderness of the upper trapezius muscle, and to improved muscle tension.
