Targeted enrichment rehabilitation is more effective than bipedal training after spinal cord injury. Figure 1. Activity tracking data

For quantitative analysis of the recordings from the T-EE cage, tracking of individual animals within the cage was conducted at weeks 3, 6, and 9 post-injuries. From each three-hour-long weekly recording, three 5-min-long segments were selected for analysis: 5-10 mins, 90-95 mins, and 150-155 mins. Distance measurements were conducted using Fiji and the MTrackJ plugin. MTrackJ was used to manually track each rat’s x/y coordinates in mm at every frame of the recording, with the time interval between frames set at 0.2 seconds. The real distances between successive coordinates were calculated and summed to determine the total distance travelled.

为开展T-EE笼（T-EE cage）录制数据的定量分析，本研究于伤后第3、6、9周对笼内的个体实验动物实施追踪。从每段时长3小时的周度录制视频中，选取三段各5分钟的片段用于分析：分别为录制起始后5~10分钟、90~95分钟以及150~155分钟的片段。本研究采用Fiji软件及MTrackJ插件（MTrackJ plugin）开展距离测量工作：借助该插件，手动提取每帧录制画面中每只大鼠的x/y坐标（单位：毫米），并将帧间时间间隔设为0.2秒。随后对连续坐标间的实际物理距离进行计算并求和，最终得到实验动物的总移动路程。
