Fall

Fall Risk Assessment Skill

Manage fall risk assessment for elderly, including fall history records, balance function tests, gait analysis, and home environment safety assessment.

Medical Safety Disclaimer

Safety Boundaries:

1. Do not handle post-fall injuries - fall injuries require immediate medical attention
2. Do not replace professional balance function assessment - balance tests require guidance from rehabilitation therapists
3. Do not provide specific rehabilitation training prescriptions - rehabilitation requires professional assessment

Can Do:

• Fall risk factor assessment
• Balance function test records (TUG/Berg/single-leg-stance)
• Gait analysis records
• Home environment safety assessment
• Fall prevention recommendations

核心流程

用户输入 → 识别操作类型 → [record] 解析跌倒事件 → 更新风险 → 保存
                              ↓
                         [tug/berg/single-leg-stance/gait] 解析测试结果 → 评估 → 保存
                              ↓
                         [home] 解析环境评估 → 更新建议 → 保存
                              ↓
                         [risk/risk-factors/interventions] 读取数据 → 显示报告

步骤 1: 解析用户输入

操作类型识别

步骤 2: 参数解析规则

跌倒事件 (record)

TUG测试 (tug)

Berg平衡量表 (berg)

单腿站立 (single-leg-stance)

步态分析 (gait)

步态异常类型

居家环境评估 (home)

步骤 3: 生成 JSON

跌倒记录数据结构

{
  "id": "fall_20250315_001",
  "date": "2025-03-15",
  "time": "10:30",
  "location": "bathroom",
  "cause": "slippery_floor",
  "injury_level": "bruise",
  "description": "在浴室因地滑跌倒，轻微擦伤",
  "required_medical_attention": false
}

TUG测试数据结构

{
  "id": "tug_20250315_001",
  "date": "2025-03-15",
  "time_seconds": 18,
  "interpretation": "基本正常",
  "fall_risk": "低风险"
}

居家环境评估数据结构

{
  "last_assessed": "2025-03-15",
  "living_room": {
    "floor_slippery": false,
    "adequate_lighting": true,
    "obstacles_removed": true,
    "rugs_secure": true
  },
  "bathroom": {
    "non_slip_mat": true,
    "grab_bars": true,
    "shower_chair": false,
    "easy_access": true
  },
  "recommendations": [
    "建议在浴室安装淋浴椅",
    "确保卧室床头灯可用"
  ]
}

步骤 4: 风险评估

Risk Factor Calculation

Low risk (0-5 points): All risk factors are under control Medium risk (6-12 points): Multiple risk factors exist, need attention and intervention High risk (13-18 points): Serious risk factors exist, immediate action required

Risk Factors

• Age (>75 years)
• Past fall history
• Balance dysfunction
• Gait abnormality
• Muscle weakness
• Vision problems
• Cognitive impairment
• Medications (>4 types)
• Chronic diseases (>3 types)
• Home environmental hazards

步骤 5: 保存数据

1. 读取 data/fall-risk-assessment.json
2. 更新对应记录段
3. 重新计算 overall_risk
4. 写回文件
