As elderly individuals increasingly become the heart of family life, ensuring their health and well-being is more important than ever—especially for those who rely on a wheelchair in their daily lives.

One commonly overlooked issue is poor sitting posture, which can lead to serious health complications and negatively affect quality of life over time.

Poor Posture Can Lead to “Spinal Deformities”

When using a wheelchair that does not properly support the body, Space between the back and the backrest can develop. This often results in unnatural sitting postures such as slouching forward or leaning downward, placing strain on various parts of the body both short- and long-term.

Risks Associated with Improper Sitting

Risks You Can See

  • Pressure sores on the lower back and tailbone due to uneven pressure or tilted posture
  • Pelvic misalignment, causing gradual shifting of the pelvic bones
  • Chronic back pain resulting from poor ergonomic positioning
  • Forward slippage, which may lead to falling out of the wheelchair

    Risks You Cannot See Immediately

  • Difficulty swallowing or drinking, increasing the risk of choking
  • Compressed lungs, resulting in shallow breathing and reduced oxygen intake
  • Abdominal pressure, leading to a reduced appetite and discomfort
