Physiology Research

KEY FINDING: The study found that after training, the participant's vastus lateralis muscle fiber area increased by 27.1%.

KEY FINDING: In fresh muscle, feedback-controlled stimulation offered minimal advantage in maintaining peak torque or mean torque over constant stimulation.

KEY FINDING: SCS applied to L2-L3 spinal segments significantly reduced the excitatory responses of L6-S2 neurons to noxious colorectal distension.

KEY FINDING: dAIH-induced recovery of breathing capacity transitions from a serotonin-independent mechanism with acute C2Hs to a serotonin-dependent mechanism with chronic C2Hs.

KEY FINDING: The relationship between muscle force and stimulation intensity is exponential.

KEY FINDING: Excitation of plantar cutaneous afferents facilitated the soleus H-reflex and the long latency flexion reflex during hip extension in SCI subjects.

KEY FINDING: SCI impairs systolic function independent of loading conditions, as evidenced by a significant reduction in end-systolic elastance.

KEY FINDING: Body weight increased in the tetraplegia group and decreased in the high paraplegia group after the intervention.

KEY FINDING: Locomotor training improved peak torque production in all participants, with the most significant increases in the plantar flexor muscles of the more-involved limb.

KEY FINDING: Women with paraplegia tended to have healthier diets, with lower calorie and fat intakes and fewer nutrient deficiencies.
