Science behind BaxBag™

BaxBag™ has the unique and fundamental design for reducing generalised back pain related to carrying a backpack. Many people are unaware or have simply accepted the way traditional backpacks affect our bodies.

Postural muscles

The cushioned design of the X made to press gently against your scapulae (shoulder blades) creates a broad stretch of the anterior pectoralis muscles (your chest). This reduces the chances of developing a kyphotic (hunchback) posture created by forward head carriage and an over compensation of the trapezius muscles.

The surrounding musculature of the upper back as well as the levator scapulae of the neck help to elevate the scapulae which is why when wearing a traditional backpack we create a more kyphotic posture because our shoulders are dragged down by the straps leaning our bodies forward.

When wearing a traditional backpack, we increase the chances of developing an anterior pelvic tilt. The supportive curved lumbar cushion reduces excessive loads to the lumbar spine and promotes the natural position of the erector spinae muscles helping keep us in extension when standing upright and allowing for a neutral pelvis.Because the straps are made to be personalized to your body, the adjustments made provide an exceptionally comfortable wearing experience as the weight is evenly distributed and optimized for your body goals.

Keeping a neutral spine is different for every person but by promoting posture ergonomics into the BaxBag™ design it stops the bag from dropping down to the lumbar area towards the glutes commonly found when wearing traditional backpacks. This increases the chances of developing a sway-back posture causing pressure on the lower back which can lead to excessive compression and possible degenerative changes in the joint complexes, weakening of the abdominals, and ligament laxity.

As we move we want our vertebrae and cartilage to remain in good alignment and good health but what is important for the musculature surrounding the spine with carrying traditional backpacks is that over time it has the possibility of increasing thoracic curvature as we tend to lean forward to compensate for the weight which adds extra stressors to the joints of the neck, upper thoracic and surrounding muscle groups limiting physical function and inducing pain.

Over time muscle and bone adaptation causes muscle length and structures to adapt to the loads placed upon them. The ‘normal’ healthy vertebrae and cartilage can become exacerbated with wear and tear through carrying unnatural loads which increase the chances of degenerative disc diseases like osteoarthritis, spondylosis, etc.

Promoting back health and the importance of carrying evenly distributed loads helps to reduce the discomfort felt by people already struggling with pain or discomfort. Keeping a neutral pelvis is fundamental in back health, BaxBag™ helps to keep you in an upright position by engaging the muscles of the rectus abdominis providing a stable and supportive foundation between the upper and the lower body which allows the cervical spine supporting the head to be in alignment with the thoracic and lumbar spine over the pelvis - without overstretching the extensors of the of lumbar spine, erector spinae, rectus femoris and quadratus lumborum preventing a weakened core and anterior pelvic tilt.

Sample study

BaxBag™ has preliminary results from a study group done to measure posture correction. A sample of 31 healthy adults aged 21-40, all able-bodied, without any clinical presentations of serious pathology, systemic illness, neurological/muscular degenerative disorder, or pre-existing conditions preventing them from carrying a loaded backpack using both shoulder straps. Digital photographs taken from a sagittal view were recorded with anatomical points marked and reduced variability measures taken into account. Conditions studied were without bag, with bag standing, and without bag standing after walking with bag for 3 minutes (post walk). Examples of changes in posture are shown here:

BaxBag™ is currently measuring forward trunk lean changes. These preliminary results are being submitted for spine biomechanics research with the use of finite element modeling, medical imaging, computer-aided design, and mechanical testing tools at the Department of Orthopaedic Surgery, National University Hospital, Singapore. This is an interdisciplinary team of Singapore's top spine surgeons and clinicians.
