Analysis of Pressure Pain Hypersensitivity, Ultrasound Image, and Quality of Life in Patients with Chronic Plantar Pain: A Preliminary Study
Abstract
To evaluate widespread pressure pain in patients with chronic plantar heel pain compared with that in healthy controls and to investigate the differences in ultrasound imaging and quality of life between these two groups. A total of 22 patients (11 female) with chronic plantar heel pain and the same number of healthy patients, matched according to age and gender, were included in this pilot study. Pressure pain thresholds (PPTs) were bilaterally assessed over the calcaneus bone, the plantar fascia, the first and fifth metatarsals, the soleus muscle, the second metacarpal, and the zygapophyseal joint of C5-C6. Plantar fascia thickness was measured via ultrasound imaging. In addition, quality of life and physical function were assessed using the Short-Form 36 (SF-36) questionnaire and the Foot and Ankle Ability Measure (FAAM) questionnaire, respectively. Analysis of covariance (ANCOVA) results showed significant differences in the PPTs at all points between the groups (P < 0.001), but not between sides. The PPTs were significantly lower in the patients than in the controls at all sites (P < 0.05). The results showed significant increases in fascia thickness at the calcaneus insertion (group: F = 74.172, P ≤ 0.001; side: F = 8.920...Continue Reading

Alternative Complement Pathway
The Alternative Complement Pathway is part of the innate immune system, and activation generates membrane attack complexes that kill pathogenic cells. Discover the latest research on the Alternative Complement Pathway.
Allergy and Asthma
Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
