Pain Sensitivity Evaluation in Respiratory Patients

3. März 2020 aktualisiert von: Marie Carmen Valenza, Universidad de Granada
Previous studies have reported that asthmatic or chronic pulmonary obstructive disease patients have an increased response to pain stimulus. However, this aspect has not been evaluated in allergic patients. Additionally, the difference in pain sensitivity between asymptomatic period crisis have not been evaluated yet.

Zeitfenster
Pressure pain threslhold
Zeitfenster: Baseline
The pain pressure thresholds (PPTs) were evaluated by an analogic manual mechanical algometer. This tool consisted of a circular platform with an area of 1 cm2 area, which was perpendicularly applied to generate progressive pressure on the skin at a 1 kg/sec rate. The points selected were chose based on a previous study in asthma patients. Patient was assessed in a seated position and pressure was applied two times at five bilateral points of the body: At two distal points, the distal thumb phalangeal and the gracilis muscle tendon at the inside of the knee. Further at three points at the chest, the costae II, distal of the midst part of the clavicle, the supraspinous muscle and the trapezius muscle's second portion, between the angulus superior at scapulae and the vertebral column.

Borg scale
Zeitfenster: Baseline
The Borg scale was used to assess the dyspnea, which is a comprehensive instrument designed to measure breathlessness in patients with respiratory pathology. Patients rated their dyspnoea from 0 to 10, where 0 represents "no dyspnoea" and 10 represents "maximum dyspnoea." A difference of 0.9 units was considered as the minimal clinically important difference (MCID), according to previous studies in patients with respiratory disease
Baseline
Leicester Cough Questionnaire
Zeitfenster: Baseline
The Leicester Cough Questionnaire (LCQ) was used to evaluate cough. This questionnaire brief, easy to administer and well-validated. It consists of 19 items with scores ranging from 1 to 7 and it is divided in three subscales: physical, psychological, and social. The minimum and maximum achievable LCQ total scores are 3 and 21, respectively. A lower LCQ score signifies more cough

Catastrophizing about Asthma Scale
Zeitfenster: Baseline
In the Catastrophizing about Asthma Scale (CAS) patients rate the extent to which 24 items expressing catastrophic thoughts and feelings about asthma are applicable to themselves (e.g., "There is nothing I can do to reduce the intensity of the asthma attack", "I worry all the time about whether the asthma attack will end", "I feel I can't go on"). The scale has two subscales, one referring to the situation of an asthma exacerbation (the exacerbation scale; 13 items), the other scale referring to daily life, whenever no exacerbation is present (general scale; 11 items). The CAS has high internal consistency (Cronbach's alpha = .93), excellent test-retest reliability (r = .94), and good construct validity.

Latency and summation
Zeitfenster: Baseline
In each testing session two series of contacts of the mechanical probe with the flexor digitorum muscle (one at ISI 3 s and one at ISI 5 s) were presented to each forearm. The forearms were always alternated between each series of contacts. Ratings of both forearms were used to control for differences in hand dominance and sites of pain.

Fatigue
Zeitfenster: Baseline
Fatigue was measured by the Fatigue Severity Scale. The Fatigue Severity Scale (FSS) was used to assess fatigue and is a 9-item scale, scored from 1 to 7, with the greater the number suggesting more severe fatigue.

Health status
Zeitfenster: Baseline
The EQ-5D was used to evaluate self-perceived health status and is divided into two sections. The first section contains five questions about mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. For each question, problems within the domain are evaluated on a three-level basis. Responders can choose between Bno problems^, Bsome problems^, or Bextreme problems^. The second part is a VAS score, which records the responder's self-evaluated health, where 0 is the worst imaginable health and 100 is the best imaginable health.
