Understanding the medical base of 8sense
8sense focusses on primary and secondary prevention of back pain. Therefore, the 8sense users will be supported in conducting an active lifestyle. The 8clip can be connected with different coaching systems (8sense – better sitting, 8sense – better training, 8sense – better lifting). The following paper explains the medical background on which the three coaching systems are based on.
8sense- better sitting
8sense aims to foster a more active daily life, dynamic sitting behavior and the users’ awareness of their own sitting behavior. Current studies report, that there is no single recommended sitting position. Some sitting positions, such as the upright one, cause less load on the intervertebral discs of the lower back compared to an arched sitting position (Huang et al.,2016). Moreover, the leaned back sitting position disburdens the intervertebral discs as well as the musculature of the back (Pape et al.,2018). Nevertheless, no static posture should be taken too long. Static sitting behavior is related to a higher risk of back pain (Zemp et al.,2016). Back pain during the last 24 hours is related
with a more static sitting behavior (Zemp et al., 2016). Thus, it’s important to change the sitting position as often as possible, to reduce the time spent sitting and to stand up more often (Barone Gibbs et al.,2018). This active behavior enhances the intervertebral discs’ diffusion and therefore, the intervertebral discs’ nutrition as well.
The individual, daily sitting behavior as well as the ratio between sitting, standing and walking per day is presented to each user via the app better sitting. Based on this data recommendations concerning physical exercise are given, in order to inspire and motivate the users to integrate more movements in their daily work routine.
