Assessment of body posture can be observed from several aspects:

Head tilt: Head tilt might be due to one side of the neck muscles being tighter than the other, causing the head to lean to one side. Prolonged posture like this may cause neck stiffness, pain, or headaches. Frequently checking phones or incorrect screen positions may be common reasons.

Shoulder level: Unbalanced shoulders might indicate that the muscles of one side of the shoulder or upper back are tighter. Maintaining this posture for a long time can lead to back, shoulder, or neck pain. Prolonged computer use, lifting heavy objects, or unbalanced exercise training could be common reasons.

Arm angle: Excessively bent arms might indicate overuse of the elbows or wrists, which can lead to muscle pain or stiffness. Typing, writing, or other repetitive motions for long durations might be the cause.

Ankle distance: A too small distance between the ankles might affect standing stability, increasing the risk of falls. Too large an ankle gap might result in uneven pressure distribution in the lower limbs, possibly causing leg pain.

Pelvic tilt: An imbalance in the pelvis might indicate that the muscles on one side of the buttocks or waist are tighter. This could result in lower back pain or functional disorders of the lower limbs. Incorrect sitting posture, prolonged standing on one side, or foot injuries might be common causes.

Trunk tilt angle: A forward-leaning trunk might indicate weakened back muscles, with tighter abdominal muscles. A backward-leaning trunk might indicate weakened abdominal muscles and tighter back muscles. Both situations might cause lower back pain or discomfort. Prolonged sitting, incorrect lifting techniques, or muscle imbalances could be common reasons.

After all, human observation is subjective and requires the accumulation of experience. But with the assistance of computer vision AI, details can be observed accurately, and values can be directly digitized.

Of course, the above evaluations provide some basic indications of body posture. As mentioned, to determine specific health issues or symptoms, a more in-depth clinical assessment is needed. If there are symptoms of pain or discomfort, it is recommended to consult a doctor or therapist early.
