Question: In his famous work on patients presenting acute with cerebellar injuries Gordon Holmes demonstrated that some exemplary patients with unilateral damage (N=3) showed a delayed start of auxometric finger movements as well as incomplete force production [1]. The aim of this study was to investigate these results in more detail. Methods: Patients presenting with cerebellar lesions (N=9, age: 51.6 years) and age and sex matched subjects (N=9, age: 51.3 years) performed a sequence of precise auxometric finger movements with a custom-made dynamometer. The apparatus consists of a hinge (58 mm legs) kept open by a leg spring at an angle of 11°. The spring had a constant of 39.4 Nmm/° resulting in a force range of 8.7 N (initial value) to 16.2 N (maximal value). Subjects had to squeeze the hinge each time a 1 kHz tone (duration: 2 s) was presented. Trial intervals varied randomly between 10 – 15 s. During each trial the tone was presented twice with a constant inter-stimulus interval of 2 s. Mean values for reaction time (RT) and movement time (MT) of both hands were compared statistically. During the procedure electro-myographic activity (EMG) of the thenar muscle (TH) and first dorsal interosseus muscle (FDI) were recorded. Results: In the patient group (CBL), RT and MT of the two movements in the sequence were significantly increased (both p < 0.05) compared with the control group (CTRL), regardless of the hand in use. Interestingly, for the right hand RT and MT of the second movement were clearly reduced (both p < 0.05) compared with the first movement (RT: 435 vs. 355 ms, MT: 374 vs. 250 ms, respectively) in CBL, indicating an improvement of movement performance when timing is predictive. The EMG-onsets of FDI were significantly later in CBL than in CTRL. Detailed analysis revealed that the mean EMG-onset asynchronicity between TH and FDI was significantly greater in CBL (right hand 72 ms, left hand 131 ms) than in CTRL (right hand 30 ms, left hand 25 ms), suggesting better co-ordination of the muscles around the thumb joint in CTRL. Conclusions: Patients presenting with cerebellar degeneration have more difficulties in starting precise auxometric finger movements. This may be, in part, due to a limited co-ordination of co-acting muscles around a joint. Nevertheless, they can improve in performing simple movements when timing remains predictive, because of a fixed interval.
