What data are generally included in plantar pressure and gait analysis reports?

Plantar pressure and gait analysis reports usually include the following core data categories:

1. Static plantar pressure data

Foot shape characteristics

Arch type (flat foot, normal arch, high arch foot) and plantar contact area distribution.

Plantar weight-bearing area ratio (e.g., 60% forefoot and 40% for rear foot during normal static standing).

Pressure distribution

Unilateral maximum plantar pressure peak and mean.

Symmetry of left and right foot pressure (e.g., center of gravity distribution deviation, front and rear pressure concentration areas).

2. Dynamic gait cycle parameters

Basic gait indicators

Step length (single step distance), stride (distance between two consecutive heel touchdowns), cadence (number of steps per minute), and speed (distance moved per unit time).

Total duration of walking cycle and proportion of support phase and swing phase (e.g., support phase accounts for 60%-65%, double support phase accounts for 28.8%).

Dynamic pressure characteristics of the plantar ‌

Peak pressure distribution of the plantar (such as heel, forefoot and other areas) and dynamic pressure curve ‌.

Load ratio of each sub-area of the plantar (forefoot, midfoot, rearfoot) and deviation of the center of pressure (COP) trajectory ‌.

III. Gait stage segmentation data ‌

Stand phase stage division ‌

Pressure changes and duration ratios of the first touchdown, load-bearing reaction, mid-support, and push-off phases ‌.

Swing phase stage division ‌

Kinematic parameters of the acceleration phase, mid-swing phase, and deceleration phase (such as changes in hip, knee, and ankle joint angles).

IV. Abnormal indicators and evaluation ‌

Common abnormal data ‌

Abnormal pressure distribution areas corresponding to inversion and pronation of the foot, arch collapse, metatarsalgia, etc. ‌.

Gait symmetry deviation (such as too short unilateral support time) or abnormal energy consumption ‌.

Balance ability test ‌

Stability of the center of gravity during static standing (such as the amplitude of left and right sway) and balance control ability during dynamic walking ‌.

V. Comprehensive analysis conclusions

Combining static and dynamic data, evaluate the impact of abnormal foot biomechanics (such as arch function and uneven joint force) on the lower limbs or spine.

Provide personalized suggestions (such as orthotic insole fitting, gait training program or postoperative rehabilitation plan).

The report data is usually collected through pressure-sensitive tablets or insole sensors, and the plantar pressure distribution and gait characteristics are presented with the help of three-dimensional visualization technology.
