초록/요약
Background: Sensitization increase responsiveness and reduce threshold of nociceptors to stimulation of their receptive field. The symptom of sensitization occurs in many disease related with nervous system or musculoskeletal system. Sensitization has two characteristics which are allodynia and hyperalgesia. Sensory and motor signals are connected and affect each other. Also, noxious sensory input “pain” affects the movement system. However, there are lack of studies investigating effects of pain induced sensitization to motor control. This study investigates the effects of sensitization induced pain on C8 dermatome on maximal voluntary force (MVF), finger enslaving (FE) and finger sharing (FS) in the maximal finger pressing tasks. Methods: Sixteen healthy right-handed young adults (eleven males and five females) performed MVF task during three days. In first day, all participants performed experimental protocol. In either second or third day, participants were divided into two groups randomly to determine the day of inducing sensitization by capsaicin on C8 dermatome of medial forearm and performed MVF task with same protocol. Before and after administering capsaicin, 42°C heat was applied for 10 minutes and 5 minutes respectively. The intensity of pain was measured by visual analog scale and von frey filaments were used to confirm sensitization in medial forearm and finger. Results: Results of this study showed that after sensitization, MVF of middle finger and all four fingers decreased significantly (p<0.05). However, FE and FS both did not show significantly difference on all fingers. Conclusion: Pain derived from sensitization of the C8 dermatome affected the finger flexor muscles together but did not affect individual finger muscles. Clinicians need to understand the characteristics of pain derived from sensitization and know the best methods of rehabilitation for patients.
