Masuda et al 9,10 have reported that standardized palpation of the masseter and temporalis muscles can evoke referred pain and sensations. The degree of pain elicited by palpation is determined by several factors, with the intensity of pressure exerted by the observer as likely the most important.…”

BackgroundThe evaluation of muscle pain and sensitivity by manual palpation is an important part of the clinical examination in patients with myalgia. However, the effects of clinical experience and visual feedback on palpation of the masticatory muscles with or without a palpometer are not known.ObjectiveTo estimate the effects of clinical experience and visual feedback on the accuracy of palpation in standardized settings.MethodsThirty‐two dentists (age 35 ± 11 years) classified as either specialists (n = 16) or generalists (n = 16) participated in this experiment. All dentists were instructed to target force levels of 500‐ or 1000‐gf, as determined on an electronic scale using either standardized palpometers or manual palpation (MP). All dentists participated in four different tests: MP, MP with visual feedback (MPVF), palpometer (PAL) and PAL with visual feedback (PALVF). Actual force values for each type of palpation from 0 to 2, 2 to 5 and 0 to 5 s were analysed by calculating target force level.ResultsThe relative differences during 2–5 and 0–5 s with 1000 gf were significantly lower for generalists than for specialists (p < .05). In generalists and specialists, the coefficients of variation and the relative differences during 2–5 s were significantly lower for PAL and PALVF than for MP (p < .05).ConclusionsThese findings suggest that the use of a palpometer, but not clinical experience with palpation of masticatory muscles, increases the accuracy of palpation, and ≥2 s of palpation with a palpometer is optimal for masticatory muscles.

BackgroundThe temporal tendon is a structure often compromised in patients suffering from temporomandibular disorders (TMD), yet its intraoral location makes a standardised assessment difficult.ObjectivesTo evaluate the variability and accuracy to target force of a newly designed intraoral extension for a palpometer device (Palpeter, Sunstar Suisse) when compared to manual palpation, in addition to clinically assessing the mechanical sensitivity and referred sensations of the temporal tendon in healthy individuals.MethodsExperiment 1: 12 individuals were asked to target on a scale 0.5, 1 and 2 kg, for 2 and 5 s by using five different methods (Palpeter, Palpeter with three different extension shapes and manual palpation). Experiment 2: 10 healthy participants were recruited for a randomised double‐blinded assessment by applying pressure of 0.5, 1 and 2 kg to the right temporal tendon with the three extensions and manual palpation. Participants rated the intensity of their sensation/pain on a 0–50–100 numeric rating scale (NRS), unpleasantness on a 0–100 NRS, and if present, they rated and drew the location of referred sensations. Repeated measures analysis of variance (ANOVA) was used in both experiments to compare differences between palpation methods. Tukey's HSD tests were used for the post hoc comparisons, and p values below .05 were considered significant.ResultsExperiment 1: The extensions showed no significant differences between them regarding reliability and accuracy for all forces and durations (p > .05). The manual method was significantly less reliable and accurate when compared to the other methods (p < .05). Experiment 2: There were no significant differences between the Palpeter extensions regarding pain intensity or unpleasantness NRS scores (p > .05), but all the extensions had significantly increased pain intensity and unpleasantness when compared to manual palpation (p < .05). Similarly, the frequency of referred sensations was similar between extensions but increased when compared to manual palpation.ConclusionsThe new Palpeter extensions proved to be significantly more accurate and have lower test–retest variability than the manual method in a non‐clinical setting. Clinically, they showed no significant differences in NRS scores for pain intensity nor unpleasantness, with no major differences in referred sensations, making any of the extensions suitable for clinical testing of the temporal tendon in future studies.

BACKGROUND A digital pain manikin is measurement tool that presents a diagram of the human body where people can mark the location of their pain to produce a pain drawing. Digital pain manikins facilitate collection of more detailed spatial pain data compared to questionnaire-based methods and are an increasingly common method for self-reporting and communicating pain. However, an overview of how digital pain drawings, collected through digital pain manikins, are analysed and summarised is currently missing. OBJECTIVE To map the ways digital pain drawings were summarised and analysed, and which pain constructs these summaries attempted to measure. Specific objectives were to: 1) identify and characterise studies which used digital pain manikins for data collection; 2) identify (a) which individual drawing-level summary measures they reported, and (b) the methods by which these summaries were calculated; 3) identify if and how multi-drawing (e.g., time series) summary and analysis methods were applied. METHODS We conducted a scoping review to systematically identify studies using digital pain manikins for data collection which reported any summary measures or analysis of digital pain drawings. We searched multiple databases using search terms related to “pain” and “manikin”. Two authors independently performed title, abstract and full text screening. We extracted and synthesised data on how studies summarised and analysed digital manikin pain data at the individual pain drawing-level as well as across multiple pain drawings. RESULTS Our search yielded 6,189 studies, of which we included 92. The majority were clinical studies (n=51), and collected data cross-sectionally (n=64). Eighty-seven studies reported at least one individual drawing-level summary measure. We identified individual drawing-level manikin summary measures related to 10 distinct pain constructs, with the most common ones being pain extent (or, pain area) (reported in 53 studies), physical location (n=28), and widespreadness (n=21), with significant methodological variation within constructs. Forty-two studies reported at least one multi-drawing summary method, with five distinct categories. Heatmaps were most common (n=35), followed by the number or proportion of participants reporting pain in a specific location (n=14). Sixteen studies reported multi-drawing analysis methods, with the most common being an assessment of the similarity between pairs of pain drawings intended to represent the same individual at the same moment in time (n=6). CONCLUSIONS We found a substantial number of studies which reported manikin summary and analysis methods, with the majority being cross-sectional clinical studies. Studies commonly reported pain extent at the individual pain drawing-level and used heatmaps to summarise data across multiple drawings. Analysis methods which went beyond summarising pain drawings were much rarer. Methodological variation within pain constructs meant a lack of comparability of methods between studies and across manikins. This highlights a need for standardisation of methods to summarise and analyse digital pain drawings, which are applicable across manikins.
