Introduction
A physiotherapy session typically lasts 20–30 minutes, which is generally appropriate. The exact duration should be adjusted based on the type of therapy, treatment goals, and individual physical condition. Physiotherapy should follow the principle of gradual progression, avoiding excessively prolonged sessions. During routine physiotherapy, it's important to follow professional guidance, adjust according to personal response, and pay attention to keeping warm and resting after treatment to achieve optimal therapeutic effects.

Generally, a physical therapy session lasting 20–30 minutes is considered appropriate. The exact duration should be adjusted based on the type of therapy, treatment goals, and individual physical condition. Details are as follows:

For common physical therapies such as heat application, infrared irradiation, and ultrasound treatment, a duration of 20–30 minutes ensures sufficient thermal or mechanical effects on the targeted area, effectively relieving pain and promoting blood circulation, while avoiding excessive stimulation due to overly prolonged sessions.

For acute injuries, such as cold compress therapy during the initial stage of a sprain, the duration should be shortened to 15–20 minutes to prevent skin frostbite. For chronic conditions like lumbar muscle strain treated with traction therapy, the duration may be slightly extended under professional guidance, although single sessions typically do not exceed 40 minutes. Individuals with weaker constitutions should reduce the duration as needed to avoid discomfort such as dizziness or fatigue.

Physical therapy should follow the principle of gradual progression, avoiding盲目 prolongation. During routine therapy, it's important to follow professional guidance, adjust according to personal response, and pay attention to keeping warm and resting after treatment to maximize therapeutic benefits.
