Pain pressure threshold algometry of the abdominal wall in healthy women

Abstract

The objective of this study was to determine the inter- and intra-examiner reliability of pain pressure threshold algometry at various points of the abdominal wall of healthy women. Twenty-one healthy women in menacme with a mean age of 28 ± 5.4 years (range: 19-39 years) were included. All volunteers had regular menstrual cycles (27-33 days) and were right-handed and, to the best of our knowledge, none were taking medications at the time of testing. Women with a diagnosis of depression, anxiety or other mood disturbances were excluded. Women with previous abdominal surgery, any pain condition or any evidence of inflammation, hypertension, smoking, alcoholism, or inflammatory disease were also excluded. Pain perception thresholds were assessed with a pressure algometer with digital traction and compression and a measuring capacity for 5 kg. All points were localized by palpation and marked with a felt-tipped pen and each individual was evaluated over a period of 2 days in two consecutive sessions, each session consisting of a set of 14 point measurements repeated twice by two examiners in random sequence. There was no statistically significant difference in the mean pain threshold obtained by the two examiners on 2 diferent days (examiner A: P = 1.00; examiner B: P = 0.75; Wilcoxon matched pairs test). There was excellent/good agreement between examiners for all days and all points. Our results have established baseline values to which future researchers will be able to refer. They show that pressure algometry is a reliable measure for pain perception in the abdominal wall of healthy women.

Widespread Pressure Pain Hypersensitivity and Ultrasound Imaging Evaluation of Abdominal Area after Colon Cancer Treatment

“…It suggests a greater sensitization in the surgical area joined to a reduced algometry levels in second metacarpal and supports the presence of secondary sensitization mechanisms in a similar way to breast cancer survivors [11]. The PPT values for abdominal wall muscles in colon cancer survivors were lower than previously reported in healthy women [20]. The magnitude of PPT differences between the colon cancer patients and healthy controls in our study was slightly higher in the supraumbilical site than the infraumbilical and lumbar areas.…”

“…The abdominal wall was assessed using four points marked bilaterally. Localized PPT points were established following previously reported methodologies [20]. The supraumbilical point was assessed 3 cm above the umbilical point inside the hemiclavicular line (the lateral border of each rectus muscle).…”

Evaluation of Pain Pressure Threshold and Widespread Pain in Chronic Low Back Pain

“…The gradually increasing force is applied over the target area until patients specify pain rather than pressure. Also, this device has been used in different areas of the body, such as the patellar tendon and abdominal wall, to assess pain pressure threshold (25,26).…”

“…По поводу латерализации болевой чувствительности данные литературы противоречивы. Ряд исследователей отмечают более высокое значение ИБП справа [5,11], в то время как в работе D. Maquet и соавт. [7], напротив, видна тенденция к более высоким значениям ИБП со стороны недоминантной руки (т.е.…”

“…Тензоалгометрия на сегодняшний день является одним из самых объективных методов определения индивидуальной болевой чувствительности при нарушениях в опорнодвигательном аппарате и в динамике реабилитационных мероприятий [2,4]. Проблеме оценки и стандартизации значений болевой чувствительности в различных отделах тела человека посвящен ряд работ [5][6][7][8][9], которые, однако, не акцентировались на исследовании паравертебральных точек. В литературе отсутствуют данные по количественным характеристикам ИБП в этих точках у здоровых лиц и у девушек с отклонениями в состоянии ПДС, определенными стандартным аппаратным методом с помощью тензоалгометрии на большой группе исследуемых.…”
