![]() ![]() Its a simple, beat-based metronome app thats more fun than a. Several aspects of anticipatory motor control can be measured: including reaction time to the first metronome cue and the ability to adapt and anticipate the beat over time.Ĭrown Copyright © 2018. Search for beats, one-shots, loops, and instrumentals by BPM, key, and instrument. Hopping at a frequency of 40-bpm seemed more challenging. This new timed hopping test may be able to detect both physical ability, and feed-forward anticipatory control impairments in people with mild MS. However, at 40-bpm, the MS group was no longer significantly different from the elderly group, even though matched controls and elderly still differed significantly. In terms of hopping characteristics, at 60-bpm, people with MS and matched controls were significantly different from the elderly group. Delay of the first hop during 60-bpm predicted cognition in people with MS (R = 0.55, β = 4.64 (SD 4.63), F = 4.85, p = 0.05) but not among control (R = 0.07, p = 0.86) or elderly subjects (R = 0.17, p = 0.57). The MS group became more delayed from the metronome beat over time whereas elderly subjects tended to hop closer to the beat (F = 4.52, p = 0.02). Hop characteristics (length, symmetry, variability) and delay from the metronome beat were extracted from an instrumented walkway and compared between groups. ![]() ![]() MetronomeBot produces the sounds at a steady tempo for nine minutes in the Youtube video below. Participants performed two bipedal hopping tasks: at 40 beats/min (bpm) and 60-bpm in random order. Triple subdivision metronome at 40 beats per minute This metronome repeatedly subdivides the beat into three equal parts with a high woodblock sound on the beat, followed by two low woodblock sounds, at 40 BPM or 40 beats per minute. Participants with MS (n = 13), matched controls (n = 9), and elderly subjects (n = 13) completed tests of cognition (Montreal Cognitive Assessment (MoCA)) and motor performance (Timed 25 Foot Walk Test (T25FWT)). We examined whether hopping to a metronome beat had the potential to detect anticipatory motor control deficits among people with mild MS (Expanded Disability Status Scale ≤ 3.5). People with mild multiple sclerosis (MS) often report subtle deficits in balance and cognition but display no measurable impairment on clinical assessments. ![]()
