Article Title: Muscle excitability testing: Age and sex dependency of normative data
Article Snippet: .. Stimulation and recording were controlled by QtracS software (©University College London, U.K., distributed by Digitimer Ltd). ..

Article Title: Cortical hyperexcitability and disease spread in amyotrophic lateral sclerosis.
Article Snippet: doi:10.1111/ene.13295 Background and purpose: Amyotrophic lateral sclerosis (ALS) is characterized by focal disease onset with a predominantly contiguous pattern of disease spread.. The pathophysiological mechanisms underlying disease progression in ALS have not been elucidated.. Given that cortical hyperexcitability has been identified as an important pathogenic mechanism in ALS, the aim of the present study was to determine whether changes in cortical function could mediate disease spread in ALS.

Article Title: Axonal Excitability Does Not Differ between Painful and Painless Diabetic or Chemotherapy-Induced Distal Symmetrical Polyneuropathy in a Multicenter Observational Study.
Article Snippet: .. QTracS software (©UCL Institute of Neurology, London, UK, available from Digitimer at www.Digitimer.com) was used to acquire and analyze the axonal excitability measures. ..

Article Title: Physiological Processes Underlying Short Interval Intracortical Facilitation in the Human Motor Cortex.
Article Snippet: .. Data acquisition and stimulation delivery were controlled by QTracS software (Digitimer Ltd., UK). ..

Article Title: Pathophysiological associations of transcallosal dysfunction in ALS.

Article Title: Abnormalities of cortical stimulation strength-duration time constant in amyotrophic lateral sclerosis.
Article Snippet: CMAP responses were amplified with a gain of 1000 and bandpass filtered (3 Hz-5 kHz) using a D440 Isolated amplifier (Digitimer, UK), and sampled at 10 kHz using a 16-bit data acquisition card (National Instruments USB-6341). .. Data acquisition and stimulus delivery were controlled by QTRACS software (Version 2017, Digitimer, United Kingdom). ..

Article Title: Axonal Excitability Does Not Differ between Painful and Painless Diabetic or Chemotherapy‐Induced Distal Symmetrical Polyneuropathy in a Multicenter Observational Study
Article Snippet: .. QTracS software (©UCL Institute of Neurology, London, UK, available from Digitimer at www.Digitimer.com ) was used to acquire and analyze the axonal excitability measures. ..

Article Title: Measurement of axonal excitability: Consensus guidelines.
Article Snippet: .. Threshold tracking typically utilises QTracS software (© UCL Institute of Neurology, London, UK, available from Digitimer Ltd at www.Digitimer.com), a nerve excitability stimulus control, acquisition and data analysis software package (Figure 4) with a number of relevant features: a choice of tracking modes for determining the step size, from fixed step (e.g., 2%) to proportional step (i.e., step size proportional to difference between actual and target response; JO UR NA L P RE -P RO OF the ability to cycle between different stimulus channels, each with different conditioning and test stimulus combinations, keeping separate records of the threshold and tracking history for each; the option to fix the amplitude of the conditioning stimulus on one channel to a specified fraction of the test stimulus on another channel, used, e.g., for latent addition and threshold electrotonus; the option to subtract the response on one channel from that on another, before comparing the response with the target response (e.g., in measurements of the recovery cycle when the conditioning-test interval is short, and the response to the conditioning stimulus overlaps with the response to the test stimulus); and the option to increment one of a number of time intervals (e.g., the conditioning–test interval), either in regular steps or in a predetermined irregular sequence, and either after a fixed number of test stimuli or only when threshold has been determined to a specified accuracy. .. Axonal excitability data generated by the TROND protocols can be analysed directly in QtracP (© UCL Institute of Neurology, London, UK, available from Digitimer Ltd at www.Digitimer.com), which creates to special text files (.MEM) for further analysis.
