什么是被动软组织放松技术---The image provided contains two photographs side-by-side, depicting a manual therapy or massage technique being performed on a person's lower leg. There are no textual questions, options, or other written information present in the image. --- **Chart/Diagram Description:** **Type:** Two photographic images illustrating a physical therapy or massage technique on the lower leg. **Main Elements:** * **Overall Scene:** Both images show the lower half of a person's body (from the thighs down, specifically focusing on the calves and feet) lying prone on a blue treatment table. Another person's hands and forearms are visible, performing a manipulation on the prone person's left calf muscle. The background is a wooden floor. * **Left Image (First Photograph):** * **Subject:** A person's bare lower legs are seen resting on a blue, padded treatment table. The left foot is visible, with the toes pointing downwards, suggesting a relaxed position or mild plantarflexion. * **Practitioner:** A pair of hands, likely belonging to a therapist or practitioner, are positioned around the calf muscle of the left leg. The hands appear to be grasping the muscle with fingers curled slightly. * **Action/Direction:** A solid black horizontal arrow is drawn over the calf muscle, pointing from left to right (towards the foot/ankle). This indicates the direction of movement or force being applied by the practitioner's hands. The hands appear to be moving distally along the calf. * **Right Image (Second Photograph):** * **Subject:** Similar to the left image, a person's bare lower legs are seen resting on the blue treatment table. The left foot is visible, also with toes pointing downwards. * **Practitioner:** The same pair of hands are again positioned around the calf muscle of the left leg, similar to the left image. * **Action/Direction:** A solid black horizontal arrow is drawn over the calf muscle, pointing from right to left (towards the knee/upper leg). This indicates the direction of movement or force being applied by the practitioner's hands. The hands appear to be moving proximally along the calf. * **Relative Position and Direction:** The images effectively demonstrate two different directions of a manual therapy stroke on the calf muscle: one moving downwards towards the ankle (distally) and the other moving upwards towards the knee (proximally).
