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:
- •Do not handle post-fall injuries - fall injuries require immediate medical attention
- •Do not replace professional balance function assessment - balance tests require guidance from rehabilitation therapists
- •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

步骤 1: 解析用户输入
操作类型识别
| Input Keywords | Operation Type |
|---|---|
| record | record - Record fall event |
| history | history - View fall history |
| tug | tug - TUG test |
| berg | berg - Berg balance scale |
| single-leg-stance | single-leg-stance - Single leg stance test |
| gait | gait - Gait analysis |
| home | home - Home environment assessment |
| risk | risk - Fall risk assessment |
| risk-factors | risk-factors - View risk factors |
| interventions | interventions - Intervention recommendations |
步骤 2: 参数解析规则
跌倒事件 (record)
| Parameter | Extraction Rule |
|---|---|
| Date | (\d{4}-\d{2}-\d{2}) or "today" |
| Location | bathroom, bedroom, living_room, kitchen, stairs |
| Cause | slippery_floor, trip, loss_balance, dizziness, weak |
| Injury | none, bruise, cut, fracture, head_injury |
TUG测试 (tug)
| Time (s) | Result |
|---|---|
| <10 | Normal |
| 10-19 | Basically normal |
| 20-29 | Mobility limited |
| >=30 | Dependent |
Berg平衡量表 (berg)
| Score | Result |
|---|---|
| 0-20 | Wheelchair required |
| 21-40 | Assistive walking required |
| 41-56 | Independent walking |
单腿站立 (single-leg-stance)
| Age | Normal Time (s) |
|---|---|
| <60 | >30 |
| 60-69 | >15 |
| 70-79 | >5 |
| >=80 | >3 |
步态分析 (gait)
| Gait Speed (m/s) | Result |
|---|---|
| >1.0 | Normal |
| 0.6-1.0 | Mobility limited |
| <0.6 | Severely limited |
步态异常类型
| Keyword | Type |
|---|---|
| shortened_step | Shortened step |
| widened_base | Widened base |
| unsteady_gait | Unsteady gait |
| shuffling | Shuffling |
| asymmetric | Asymmetric |

步骤 3: 生成 JSON
跌倒记录数据结构
json
{
"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

"date": "2025-03-15",
"time_seconds": 18,
"interpretation": "基本正常",

}
居家环境评估数据结构
json
{
"last_assessed": "2025-03-15",
"living_room": {
"floor_slippery": false,
"adequate_lighting": true,
"obstacles_removed": true,
"rugs_secure": true

]
}
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
- •读取
data/fall-risk-assessment.json - •更新对应记录段
- •重新计算 overall_risk
- •写回文件
