Repeated Muscle Injury as a Presumptive Trigger for Chronic Masticatory Muscle Pain

Figure 2

Maximal isometric torque produced before and at various times after eccentric muscle contraction. Solid line is masseter muscle and dashed line is tibialis anterior muscle. Note equivalent loss of force for Masseter and tibialis anterior at day 0 after eccentric contraction. Asterisks denote significant reductions from initial maximal torque. masseter = 60 eccentric contractions, tibialis anterior = 150 eccentric contractions, masseter 𝑛 = 6 , and tibialis anterior 𝑛 = 2 5 .
