Reviewed in Japan on March 16, 2025Verified Purchase数年前に交通事故にあい、気圧の変化で、首や肩のこりが酷くなることがありました。
しかし、この温熱低周波治療器を使用すると、首、肩の筋肉の緊張の緩和された感が強く肩こり頭痛も緩和されました。
(個人的感想ですw)
低周波治療器と温熱低周波治療器どちらかを購入するか悩みに悩みましたが、温熱低周波治療器を購入して正解でした。
星が四つなのは、治療が終わったときに何か音がなったりして欲しいのと、Amazonでオムロン製の交換マットが販売されていないため。

Reviewed in Japan on November 19, 2024Verified Purchase定期的に発症する腰痛、臀部痛(坐骨神経痛)に悩まされています。先日、整形外科で低周波治療器をあててもらったところその後数時間、腰の重みが減り楽に過ごせたのですぐに色々調べてこちらの機種を購入してみました。整形外科のものと比べるとダイエットや腹筋を鍛えるEMSベルトみたく表面だけでピリつく低周波感が少しありますが、パッドを患部にピンポイントで貼れて温めながら刺激するためなかなか気持ち良いです。特に「深部」の治療パターンが気に入ってます。温熱と低周波の組合せは本当に効果高そうです。お風呂上がりなどであれば低周波のみ30分というのも良い感じです。パッドは10〜20回くらい貼っててそろそろ貼り付きが弱くなってきたかな?と感じます。面倒くさがりな方で定期的なパッド交換とか面倒なので、別で購入した粘度の高いジェルを今度試してみます。

Reviewed in Japan on March 8, 2025Verified Purchase確かに刺激はありますが患部が楽になる印象はない。手でもんだほうが楽になる。

Reviewed in Japan on December 10, 2024Verified Purchase小さいので弱いかな?と思っていましたが、さすがオムロンさん!強度を20にすればかなり効きます。強めが好きなので良いです♪
整形外科や整体院で受ける電気治療と同じ物が手軽に家で出来るので買って良かったです。
パットの粘着力があまり持たなそうな印象。
