Children with profound intellectual and multiple disabilities (PIMDs) and typically developed (TD) children were measured during tandem ski (TS) activity to assess its effect on postural control and cardiac activity by a multidisciplinary team from Lausanne (HES SO, ISSUL and CHUV). Inertial Physilog® sensors were placed on the participants (on head, pelvis, seat and trunk with a special ECG module) and a GPS module in the pilot’s pocket to analyze the movements and adjustment of their body segments and to monitor the speed and trajectory of the TS.
They conclude: “Tandem skiing appears to elicit active postural adaptations and increased heart rate in children and youth with PIMD to a similar extent to those of their TD peers. Therefore, tandem skiing can be considered a rare genuine sport activity for this category of children with special needs, and in our opinion, its practice should be encouraged on a regular basis.”
- Purpose: The objective of study was to determine the effect of tandem ski (TS) activity on postural control and cardiac activity in children with profound intellectual and multiple disabilities (PIMDs).
- Method: Twenty children with PIMD and 20 age-matched controls (typically developed (TD) children) participated. Body segment movements were measured with inertial sensors (Physilog®) placed on the head, C7, trunk (including ECG) and pelvis with a seat reference. Each participant was measured during a 12-turn slalom pattern.
- Results: In each group, significant differences were observed between the head vs. trunk and head vs. pelvis angular speeds (p<0.001). In both groups, heart rate differed significantly during rest (PIMD 99 bpm, TD 97 bpm), exercise (PIMD 140 bpm, TD 139 bpm; rest vs. exercise p<0.001) and recovery (PIMD 101 bpm, TD 107 bpm; exercise vs. recovery p<0.001).
- Conclusions: In children with PIMD, TS elicits active postural control associated with cardiac activities similar to that of the controls.
