護理師觀察病人使用拐杖，哪項觀察結果顯示病人使用方式正確？
A nurse observes a client using a cane. Which observation indicates the client is using the cane correctly?
- AThe elbow is kept straight when holding the cane持拐杖時手肘保持伸直
- BThe cane is moved forward with the healthy leg拐杖與健康腿同時向前移動
- CThe cane is held on the injured side拐杖握在受傷側
- DThe cane is held on the unaffected side✓ 正解拐杖握在未受損側
使用拐杖時，應將拐杖握於健側（患肢對側），以模擬正常步態並擴大支撐面積，將重量轉移至健側手部。若握於患側，支撐效果不足且容易跌倒。拐杖應與患肢同時移動，維持支撐穩定度。手肘應維持約 15-30 度的屈曲，而非完全伸直，以利緩衝與承重。
When using a cane, it should be held on the unaffected (opposite) side to simulate a normal gait and widen the base of support, transferring weight to the unaffected hand. Holding the cane on the affected side provides insufficient support and increases fall risk. The cane should be advanced simultaneously with the affected leg to maintain stable support. The elbow should maintain approximately 15-30 degrees of flexion rather than full extension, to allow for shock absorption and weight bearing.
台美皆遵循 COAL（Cane Opposite Affected Leg）原則，但台灣衛教常強調拐杖長度設定（大轉子高度），美國則更重視動態步態評估。
