Outcome Measures

Primary Outcomes (4)

• Postural Assessment

  Each participant was fitted with two Shimmer3 sensors (Shimmer Sensing, Dublin, Ireland) on their head (occiput) and low back (over S2 tubercle) (see Figure 2) with a third Shimmer3 sensor placed on the surface (ground or rocker board). Participants were asked to perform a series of four postural tasks with two surface conditions (floor or rocker board) and two variations of each (eyes open or closed, and AP or ML rocker board direction). The conditions were randomized (using REDCap) such that either both floor or both rocker board conditions were performed first, with the remainder performed second. The order of variation within the surface type was held consistent for all occasions; eyes open then eyes closed on the floor, and AP then ML rotation direction on the rocker board.

  Post Treatment on Day 1

• Postural Assessment

  Each participant was fitted with two Shimmer3 sensors (Shimmer Sensing, Dublin, Ireland) on their head (occiput) and low back (over S2 tubercle) (see Figure 2) with a third Shimmer3 sensor placed on the surface (ground or rocker board). Participants were asked to perform a series of four postural tasks with two surface conditions (floor or rocker board) and two variations of each (eyes open or closed, and AP or ML rocker board direction). The conditions were randomized (using REDCap) such that either both floor or both rocker board conditions were performed first, with the remainder performed second. The order of variation within the surface type was held consistent for all occasions; eyes open then eyes closed on the floor, and AP then ML rotation direction on the rocker board.

  Pre Treatment on Day 2

• Postural Assessment

Study Arms (2)

Lower Extremity First (LEF)

EXPERIMENTAL

The treatment was a non-specific long-axis distraction to the ankle, knee, and hip provided was at the discretion of the clinic doctor (over 25 years experience).

Procedure: Lower Extremity First (LEF)

Upper Extremity First (UEF)

EXPERIMENTAL

The treatment was a non-specific long-axis distraction to the shoulder, elbow and wrist provided was at the discretion of the clinic doctor (over 25 years experience).

Procedure: Upper Extremity First (UEF)

Interventions

Lower Extremity First (LEF) PROCEDURE

The intervention for the LEF group was a non-specific long-axis distraction to the ankle, knee, and hip or shoulder, elbow and wrist provided was at the discretion of the clinic doctor (over 25 years experience).

Lower Extremity First (LEF)

Upper Extremity First (UEF) PROCEDURE

The intervention for the UEF group was a non-specific long-axis distraction to the shoulder, elbow and wrist provided was at the discretion of the clinic doctor (over 25 years experience).

Upper Extremity First (UEF)
