“…The strength values that were recorded (Table 6.3) are within the normal range for the subjects in the reference sample Fain & Weatherford 2016;Nilsen et al 2012), although they are slightly lower than the mean values in the literature. This is probably because the sample consists of persons who carry out work that does not require manual strength (academic setting or similar).…”

“…Manual tasks, such as palmar grip and lateral pinch, are study objects since the hand combines two different functions: strength and dexterity. In addition, palmar grip strength is predictive of future disabilities, morbidity and mortality, not only in older adults, but also in middle-aged and young people 6,[33][34][35] , which strengthens the importance of studies in this area.…”

“…In the evaluation of results of patients treated for upper limb disorders, various clinical parameters are used, among which we highlight the lateral pinch and palmar grip strength 5,6 . Individuals with palmar grip and lateral pinch dysfunction present deficit in daily life activities, thus the return of strength to this body segment is necessary 7,8 .…”

“…With the same goal, Araujo et al 15 conducted a populational study of pinch strength with pinch gauge™ dynamometer and concluded that the strength of lateral pinch in the male gender presents an average of 9.9±1.9 kgf and 6.7±1.4 kgf in the female gender. Studies related to normative data for grip and pinch are presented in different countries and serve as a reference in clinical practice in order to compare possible changes of grip strength and pinch, arising from different lesions of the upper limb 6,16 . Tang et al 17 describe that changes in biomechanical parameters of the wrist can be an important cause of diseases and dysfunctions.…”

RESUMO O objetivo deste estudo foi avaliar os efeitos de um protocolo de fadiga dos músculos extensores de punho na força de preensão e da pinça lateral através da dinamometria e eletromiografia de superfície (EMG). Foram selecionados 40 indivíduos do sexo masculino, divididos em dois grupos: preensão ou pinça lateral. O protocolo de fadiga foi baseado no teste de 1 Repetição Máxima (1-RM), seguido da realização do movimento de extensão de punho repetidas vezes com carga de 75% da 1-RM. Os voluntários realizaram as tarefas de preensão ou pinça lateral associadas à dinamometria. A EMG foi realizada para ambos os grupos, analisando o comportamento, segundo o protocolo, pela frequência mediana (FM) do extensor radial do carpo (ERC), do extensor ulnar do carpo (EUC) e do flexor superficial dos dedos (FD). A dinamometria de preensão ou pinça lateral e a EMG foram realizadas antes e após o protocolo de fadiga para ambos os grupos. O protocolo de fadiga foi eficaz na diminuição da força de preensão palmar (43,5±3,85 kgf inicial e 36,50±5,1 kgf final) e da pinça lateral (10,26±1,01 kgf inicial e 8,54±0,86 kgf final), bem como na diminuição da FM, sugerindo uma condição de fadiga do EUC no grupo preensão. Os achados do presente estudo possibilitam relacionar a fadiga dos extensores de punho à diminuição de força em atividades funcionais, como a preensão, o que pode implicar em disfunções musculoesqueléticas do membro superior.

“…To validate whether the new device produced MVC readings that were the same as those reported in the literature, we compared our data to data from eight previous studies that assessed hand grip strength in pediatric populations [42,43,[49][50][51][52][53][54]. These studies all used a commercially available hand grip dynamometer with six of the eight using the gold-standard Jamar dynamometer.…”

Background While new therapies are continuously introduced to treat muscular dystrophy, current assessment tests are challenging to quantify, cannot be used in non-ambulatory patients, or can de-motivate pediatric patients. We developed a simple, engaging, upper-limb assessment tool that measures muscle strength and fatigue in children, including children with muscular dystrophy. The device is a bio-feedback grip sensor that motivates children to complete maximal and fatiguing grip protocols through a game-based interface. Methods To determine if the new system provided the same maximum grip force as what is reported in the literature, data was collected from 311 participants without muscle disease (186 M, 125 F), ages 6 to 30, each of whom played the four minute grip game once. We compared maximum voluntary contraction at the start of the test to normative values reported in the literature using Welch’s unequal variances t-tests. In addition, we collected data on a small number of participants with muscle disease to determine if the assessment system could be used by the target patient population. Results Of the 311 participants without muscle disease that started the test, all but one completed the game. The maximum voluntary contraction data, when categorized by age, matched literature values for hand grip force within an acceptable range. Grip forced increased with age and differed by gender, and most participants exhibited fatigue during the game, including a degradation in tracking ability as the game progressed. Of the 13 participants with muscle disease, all but one completed the game. Conclusions The study demonstrated the technical feasibility and validity of the new hand grip device, and indicated that the device can be used to assess muscle force and fatigue in longitudinal studies of children with muscular dystrophy.
