What Systematic recommends
Where to start
- Place the shoes with their heels against the wall, about shoulder-width apart. Stand barefoot with your heels touching the toes of the shoes.
- Push the hips backward toward the wall as the shoulders move forward and down. Maintain a neutral spine throughout the movement.
- Keep full tripod-foot contact with the floor and keep the knees slightly soft rather than fully locked.
Condensed from the published Development Pathway (The Toe Touch Screen: Wall-Supported Hip Hinge). This is a starting point, not a training program or medical advice.
More than hamstrings
The lower back contributes as the body folds toward the floor, and so do the pelvis and the hips. The result depends on more than one region.
Tissue length is one part of it. Systematic calls this posterior-chain extensibility: the available length of the tissues that can influence how the pelvis and trunk move. A study of the toe-touch movement found that people with shorter hamstrings moved their pelvis less, which changed how the bend was distributed through the trunk.
How the bend is shared
Research on lumbopelvic rhythm, the way the lower spine and pelvis move together, shows that a forward bend is spread across the lower back, the upper back, and the pelvis and hips. The lower spine and pelvis contribute differently through the movement.
That split is not fixed. It varies with age and with the task. Fatigue and a history of pain change it too, which is one reason two people's forward bends can look quite different.
What a limited result can and cannot tell you
Systematic describes the toe touch through three ideas. The first is integrated lumbopelvic motion: how the lower back shares the bend with the pelvis and hips. The second is posterior-chain extensibility. The third is movement strategy: how you organize the bend to reach the floor while keeping the required knee and tempo standards. The test also works as a movement-clearance screen.
A limited result can reflect any of these. It can also reflect how much the hips, pelvis or spine contribute, or pain and protective sensitivity. The test does not say which structure is responsible.
The evidence
Each cited source is labeled according to how it supports the particular claim on this page. Direct test evidence, underlying-capacity findings and population reference values are distinguished from Systematic-defined protocols and standards. Historical development notes are retained internally rather than presented as public evidence. A study of an underlying capacity is never presented as validation of the Systematic test itself.

Underlying-capacity evidence
Vazirian et al. (2016). Lumbopelvic rhythm in the sagittal plane: A review of the effects of participants and task characteristics. International Musculoskeletal Medicine.
What it found. A forward bend is spread across the lower back, the upper back, and the pelvis and hips. How the lower spine and pelvis share it varies with age and task, and with fatigue and pain history.
What it does not show. It does not show that a limited toe touch points to one tissue, and it does not link toe touch results to health outcomes.

Direct test evidence
Gajdosik et al. (1994). Influence of hamstring length on the standing position and flexion range of motion of the pelvic angle, lumbar angle, and thoracic angle. The Journal of orthopaedic and sports physical therapy.
What it found. During a standing toe-touch movement, people with shorter hamstrings moved their pelvis less, which changed how the bend was distributed through the trunk.
What it does not show. It did not use the exact Systematic protocol, and it does not show that hamstring length alone explains every result.
The Systematic Healthspan Assessment is a physical baseline. It is not a diagnosis, and it does not estimate a biological age, a disease risk or a lifespan.
