A partial extraction of the PD-Q (Chinese version)
Examples from PD-Q
There are 3 questions from which the patient may elect to give a score on a NRS from 0 (none) to 10 (max.), e.g. how would you assess your pain now at this moment, your strongest pain and your pain on average during the past 4 weeks?你會怎樣評估你這一刻的痛楚?
The questionnaire is accompanied by four pictorial representations of aspects of pain and the patient should mark the picture that best describes the course of pain, e.g. persistent pain with slight fluctuations, persistent pain with pain attacks, pain attacks without pain between them, pain attacks with pain between them.請標誌下列哪一幅圖最能形容你痛楚的過程.
The questionnaire offers a mannequin with front and backside to draw the pain location, e.g. please mark your main area of pain and if it radiates to other regions of your body, please draw the direction in which the pain radiates.請標誌你主要痛楚的部位.
There are 7 questions which the patient has to answer by ticking one out of 6 optional boxes (never, hardly noticed, slightly, moderately, strongly, very strongly). The questions relate to 7 specific descriptor items within the painful area: 1. Burning 火燒 2. Tingling or pricking 輕微針刺或刺痛 3. Allodynia (light touching) 輕觸衣物 4. Sudden pain attacks like electric shocks 觸電的間歇性痛楚 5. Thermal pain (cold or heat, like bath water) 冷或熱溫度(冷水浴/熱水浴) 6. Numbness 麻痹 7. Hyperalgesia (slight pressure) 輕壓The 7 questions lead to a score with a max of 35. This is transferred to page 2, where the score has to be add up depending on the marked pain behavior pattern and the pain radiation, ending up in a final score between 0−38 (screening result 0−12 = negative; 13−18 = unclear; 19−38 = positive).
