JOURNAL FREE ACCESSObjectives: To investigate the short-term effects of low-frequency repetitive transcranial magnetic stimulation (rTMS) over the motor cortex on writing parameters in patients with writer's cramp. Design: Comparisons between writing performance before and after a 25-minute train of 1-Hz rTMS (1, 500 stimuli) at 95% intensity of the motor threshold. Setting: Outpatient clinic at a department of rehabilitation medicine in a university hospital in Japan. Subjects: Five healthy subjects (mean age, 28 years, 4 males) and 5 patients with writer's cramp (mean age, 27 years, 4 males). Main outcome measures: Using a simple writing pressure gauge, maximum and average writing pressure; degree of variation in writing pressure, which reflects the writer's skill in writing; and writing time, which is the amount of time required. Results: After patients received rTMS all writing parameters improved, in particular, the degree of variation decreased with significance (p<0.01, three-way ANOVA). Conclusions: In writer's cramp suffers, low-frequency rTMS over the motor cortex can improve handwriting. The electronic pen is an easily used instrument that is helpful for analyzing writing patterns.View full abstractDownload PDF (781K) -

JOURNAL FREE ACCESSForty-one patients with an average age of 64±9 years were recruited for this study from our clinic. In the 10-second grip and release test, the first of the two test administered, each patient was asked to grip and release as many times as possible during a ten second period. Our second test, the simple walking test, measured the time and number of steps a patient took to walk comfortably a distance of 15 meters and back. The 10-second grip and release test averaged 14.5 (±4.8). The time and number of steps for the simple walking test averaged 25.1 (±8.2) and 51.7 (±13.1), respectively. JOA motor function scores were also measured and these were 2.4 (±0.8) in the upper extremities and 2.3 (±0.9). The 10-second grip and release test correlated significantly (CC=0.37, p=0.02) with the JOA motor function score for the upper extremities. The time and number of steps required for the simple walking test correlated significantly with the JOA motor function score for the lower extremities (CC=0.41, p=0.009; CC=0.45, p=0.004). The 10-second grip and release test and the simple walking test can clearly delineate patients with spinal disorders and paraparesis and are therefore useful as diagnostic indicators.View full abstractDownload PDF (425K) -

JOURNAL FREE ACCESSA contracting muscle generates a pressure wave due to the lateral dimensional change in active muscle fibers, which is detectable with vibration transducers such as accelerometers and microphones on the body surface overlying the muscle. The recording of this pressure wave is referred to as the mechanomyogram (MMG). The MMG is the mechanical counterpart of myoelectrical activity. The MMG amplitude, when elicited by electrical stimulation, increases with the intensity of stimulation, although at high stimulation rates a reduction in the MMG amplitude occurs due to mechanical fusing of the motor unit activity. These properties indicate that both the number of recruited motor units and their firing rate influence the MMG. It is possible that the MMG is a useful way of indicating force, evaluating muscle fatigue, controlling prostheses, determining muscle contractile properties, and estimating the motor unit activation strategy. The present review article focuses on the introduction of the MMG in clinical examinations and in diagnosing neuromuscular diseases. The time and frequency domain parameters of the MMG during voluntary muscle action and electrical stimulation have been used in previous clinical studies. However, only a small number of clinical MMG studies and papers, i. e., less than several score have been published in the relevant international journals.View full abstractDownload PDF (1093K)
