台中大甲鎮瀾宮媽祖將在4月5日起駕遶境，大甲李綜合醫院醫師吳啟明提醒，骨質疏鬆患者要注意，切勿快速鑽轎底、彎腰角度過大；長時間走路應選擇有氣墊的鞋子，避免引起足底筋膜炎。

大甲李綜合醫院骨科主治醫師吳啟明指出，白沙屯媽祖進香期間，曾1天有4名香燈腳送進急診室，有人感冒累到昏倒，還有人在鑽轎腳時，因短時間迅速變化動作，背部受傷動彈不得，送醫治療。

吳啟明表示，40多歲的男子，當時跟著朋友參加白沙屯媽祖進香，從路邊緊急跑到隊伍前方，想要鑽神轎祈求媽祖庇佑，快速跪趴後，卻站不起來，緊急送醫治療。

吳啟明說，男子背部一陣劇痛，幾乎動彈不得，緊急送到急診室，馬上X光檢查，研判是在短時間內快速變化動作，又沒有暖身，導致背部拉傷，給予用藥休息後才離院。

吳啟明表示，患有骨質疏鬆、膝蓋受損或脊椎受傷的患者，在遶境、鑽鑾轎時更要注意，曾有位骨鬆患者，稍微用力打噴嚏或身體扭了一下，或彎腰搬重物，快速鑽鑾轎，引發背痛，都是骨質疏鬆造成。

The horn antenna has a distinctive design that is enlarged towards the end. Horn antennas typically feature a directional radiation pattern with a high antenna gain of 10-20 dBi, some antennas have a higher gain such as the standard horn antenna up to 25 dBi. Horn antennas feature a low VSWR and a wide impedance bandwidth.

Double Ridged Horn Antennas are very popular from 200 MHz frequency to higher frequencies up to 40GHz. We have recently extended the usage frequency of this antenna up to 60 GHz.

This antenna's operating frequency has recently been increased to 60 GHz. The research process for the product line is still ongoing but is planned to be completed this year. To receive the most recent price and technical information on the new product, please contact us for more information.

吳啟明指出，他看到很多媽祖的信眾，不少人是年紀比較大的長輩，如果罹患骨鬆，不小心輕微跌倒，或是被人群猛力撞擊倒地，最嚴重恐會引發腰椎壓迫性骨折。

吳啟明建議，參加繞境長時間走路，一定要選1雙有氣墊、鞋頭較寬的款式，並穿壓力襪，才能減輕雙腳及脊椎的負擔，否則引發足底筋膜炎，惡性循環不治療，就會形成骨刺。

吳啟明說，遶境要衡量自身身體健康狀況，行走時背包不宜背過重，背包肩帶調短一點，避免重心往後傾影響脊椎，鑽鑾轎前最好做伸展動作暖身，避免受傷。
