Abstract EN
Intention tremor is related to lesions in the cerebellum or connected pathways.
Intention tremor amplitude decreased after peripheral arm cooling in patients with multiple sclerosis (MS), likely caused by a reduction of muscle spindle afferent inflow, while amplitude increased when muscle spindles were artificially stimulated by tendon vibration.
This study investigated the contribution of peripheral reflexes to the generation of MS intention tremor.
Tendon reflexes of biceps, triceps, and brachioradialis, muscles were measured, using an electromechanical triggered reflex hammer.
MS patients with (n = 17) and without (n = 17) upper limb intention and 18 healthy controls were tested.
Latency of brachioradialis, biceps, and triceps tendon reflexes was greater in MS patients with tremor than in healthy controls and MS patients without tremor (except for the triceps reflex).
Peak and peak-to-peak amplitude were not different between groups.
It is concluded that tendon reflexes were delayed but not enlarged in MS patients with tremor.
