Footwear with a curved sole profile has become popular due to the proposed benefits to gait, posture and altered muscle activity and tone. In addition, rocker profiled footwear are one of the most commonly prescribed therapeutic shoes [1–4]. The altered movement of the body over the foot due to the curved sole profile is assumed to alter the position of the hips and thereafter the trunk, spine and perhaps the head too. This could have some benefits for those with back pain . However, whilst evidence for the effects on the lower limb is becoming comprehensive [1–4], there is a paucity of information for any effects on head and trunk posture.
To investigate the effect of rollover footwear on head and trunk posture during standing.
Material and methods
Head and trunk posture data of ten healthy female participants(age:24.5±1.8 years) was collected during one minute of quiet standing in two conditions (1) barefoot and (2) rollover footwear (Perfect Steps). The positions of 11 markers mounted on the spinous processes of S2, L5, L3, L1, T11, T9, T7, T5, T3, C7 and midpoint of forehead were collected by an eight-camera motion capture system at 100 Hz. The planar angles of head and neck, and the radii of thoracic and lumbar curve in the sagittal plane were calculated using an approach described by Forghany et al .

The current study showed that rollover footwear is able to modify head and trunk posture in quiet standing compared to barefoot. Participants stood more erect in footwear than barefoot. These shoes could therefore have a role in the management of some conditions where an increase in back extension is desirable but the clinical relevance of those changes remains to be determined.
