A rehabilitation pressure ball is used to solve the problem that the conventional pressure ball cannot remind the user to rehabilitate. The utility model comprises: a holding portion, which is an elastic material and has a chamber inside; and a counting member disposed in the chamber, sensing a pressure value applied to the holding portion by a pressure sensor, A processor electrically connects the pressure sensor, a power source and a warning component, and the processor receives and determines whether the pressure value is not less than a pressure threshold. If the determination result is no, the warning component emits a warning tone.一種復健用壓力球,用以解決習知壓力球無法提醒使用者進行復健的問題。係包含:一握壓部,為一彈性材質且內部具有一容室;及一計數件,設置於該容室內,以一壓力感測器感測施加於該握壓部的一壓力值,以一處理器電連接該壓力感測器、一電源及一警示元件,該處理器接收並判斷該壓力值是否不小於一壓力門檻值,若判斷結果為否,則該警示元件發出一警示音。
