The evidence of efficacy of therapeutic horse riding in children with cerebral palsy is increasing. However, there are limitations in applying it because of scarce of experts for hippotherapy and the hassle of going to the place for horse riding. Therefore, some people apply the horse riding simulator instead of horse riding for the therapeutic purpose. The study aimed to determine the difference between the movement and heart rate response on the actual horse and the device.
The participants were 12 children with cerebral palsy (GMFCS level I-III) aged 5-12 years recruited from university rehabilitation hospital. Five were boys, and eight were bilaterally involved. The body movement was monitored by accelerometer wearing at the waist during the beginner mode of the simulator and the horse riding. And heart rate was monitored by wireless heart rate monitor equipment. Movement of 3 axes, x, y, z, and monitored heart rate was analyzed by Data Analysis Software.
The movement of the y-axis was significantly less during the horse riding simulator compared to real horse riding, 300.27 ± 277.22 and 210.71 ± 243.70, respectively (P < 0.05). However, movement of x- and z-axes significantly more during the simulator. The axis x movement were 649.89 ± 337.24 and 1050.44 ± 379.00, and axis z movement were 840.66 ± 406.85 and 1147.95 ± 414.10 during horse riding and simulator exercise, respectively (P < 0.05). The motion tracked in three axes is presented in Figure 1 and 2. The variability of heart rate on equipment was significantly less than the real horse riding (P = 0.001) (Figure 3).
On a horse, there is a rhythmical up and down movement while the horse is walking. However, on the simulator equipment, the movement of the y-axis was less, but the movement of x- and z-axes was significantly more than the horse riding. Although total vector magnitude of movement was more on the simulator, the variability of heart rate was significantly more during the real horse riding. Data comparing the horse riding and horse riding simulator is scarce. In addition to movements, we tracked variations of heart rate but, further study about the simulator’s effect on postural reaction and gross motor function is needed. |
