“…A wide range of methodologies has been employed, but the validity and reliability of these measurements have been little discussed. Measurements commonly employed include the ability to sustain sub maximal loads, between 20 and 80% of maximum strength, for the longest time possible, as well as strength deterioration indices measured before and after consecutive contractions (Jones, Robertson, & Figoni, 2009;Reuter et al, 2011;Wallström & Nordenskiöld, 2001). In the present work, the slope of the regression curve was used to represent the deterioration in the force produced during a single measurement.…”

“…The gold standard for measuring hand strength is the Jamar hydraulic dynamometer, recommended by the American Society of Hand Therapists (ASHT) (Fernandes & Marins, 2011;Moreira, Godoy, & Junior, 2001). On the other hand, electronic instruments provide larger amounts of data through time with greater precision, and efforts have been made to combine different sources of information during measurements of muscular endurance (Oliveira, 2011;Reuter, Massy-Westropp, & Evans, 2011).…”

Abstract-This study aimed to identify useful electronic grip dynamometry parameters to track differences between trained (TR) and untrained (UT) participants, and between dominant (DO) and non-dominant (ND) limbs as a consequence of upper limbs muscle fatigue following 10 RM tests of the brachial biceps. This experimental study with transversal design involved 18 young adult males, of whom 9 were untrained and 9 were experienced in resistance training.Isometric grip force was evaluated (30 seconds long) previous and after 10RM tests by means of a G200 Model grip dynamometer with precision load cell (Biometrics®). Significant differences between initial and final measurements were found only for trained participants: Peak force for TR-DO (67.1 vs 55.5 kgf, p = .0277); Raw average for TR-DO (46.96 vs 42.22 kgf, p = .0464), and for TR-ND (40.34 vs 36.13 kgf, p = .0277). Electronic grip dynamometry efficiently identified upper limbs fatigue in trained participants, being raw average measurements the best parameter.Keywords: muscle strength dynamometer, muscle fatigue, hand strength, resistance training.Resumo-"Rastreamento de fadiga de membros superiores por meio da dinamometria eletrônica." Objetivou-se identificar parâmetros da dinamometria eletrônica de preensão palmar úteis para monitorar diferenças entre indivíduos treinados (TR) e não treinados (UT) e entre membros dominantes (DO) e não dominantes (ND) após indução de fadiga pelo teste de 10RM para bíceps braquial. Tratou-se de estudo experimental, transversal, envolvendo 18 homens adultos jovens, 9 não treinados e 9 experientes em treinamento resistido. Avaliou-se a força isométrica de preensão palmar (por 30 segundos) antes e após o teste de 10 RM por dinamômetro de preensão com célula de carga de precisão modelo G200 (Biometrics®). Houve diferença significativa entre valores iniciais e finais somente para treinados: Pico de força para TR-DO (67,1 vs 55,5 kgf, p = 0,0277); média bruta para TR-DO (46,96 vs 42,22 kgf, p = 0,0464) e para TR-ND (40,34 vs 36,13 kgf, p = 0,0277). A dinamometria eletrônica mostrou-se eficaz em identificar a fadiga de membros superiores nos participantes treinados, sendo a média bruta o melhor parâmetro.Palavras-chave: dinamômetro de força muscular, fadiga muscular, força da mão, treinamento de resistência.Resumen-"Seguimiento de fatiga de miembros superiores mediante dinamometría electrónica."

“…During this face-to-face assessment, the examiner was physically present to supervise the testing session and actively led the participant through all functional tests in line with recommended guidelines (Holland et al, 2014;Podsiadlo & Richardson, 1991;Reuter et al, 2011). The same walking aids and footwear were used for both telerehabilitation and face-to-face assessments.…”

“…Each test was measured twice, with the average of the two tests recorded. Maximum grip strength for each hand was measured three times with a hand-held dynamometer (Jamar) as described previously (Reuter et al, 2011), and the best measurement used in the analysis as maximum voluntary contraction, in kilograms. Quadriceps strength was also measured three times with a hand-held dynamometer (Lafayette manual muscle tester) as per previous methodology (O 'Shea et al, 2007) with an adjustable strap, and the best measurement in kilograms was used in the analysis.…”

Providing Heart Failure Rehabilitation in the Home via Telerehabilitation

Exercise is effective for patients with chronic heart failure (CHF). Despite this, many patients are unable to access traditional exercise-based rehabilitation programs for various reasons, such as transport difficulties and program availability. Telerehabilitation, in which telecommunication technologies are used to provide rehabilitation at a distance, is an alternative approach which may overcome some of these barriers.The current literature suggests that telerehabilitation is effective in patients with cardiopulmonary diseases. However the majority of studies focus on phone-based interventions, so there is a need for more studies on the use of video-based telerehabilitation programs. Video-based telerehabilitation is a new approach which enables patients to exercise in the comfort of their homes, whilst maintaining synchronous audiovisual communication. This approach enables the clinician to watch patients performing the exercises and to provide real-time feedback and modification as required, as well as facilitate the development of rapport between the clinician and patients, and peer support amongst patients. Video-based telerehabilitation also presents a potential way to conduct remote assessment of functional exercise capacity.This thesis aimed to explore a new service delivery model for providing heart failure exercise-based rehabilitation programs. The thesis commences with a systematic review of telerehabilitation in patients with cardiopulmonary diseases (Study 1, Paper 1). The next study aimed to determine the suitability of the timed up and go test (TUGT) as an outcome measurement in heart failure rehabilitation programs (Study 2, Paper 2). In addition, the validity and reliability of telerehabilitation assessments of functional tests including the TUGT were examined in patients with CHF (Study 3, Paper 3). A randomised controlled trial determined the feasibility and effectiveness of a home-based heart failure telerehabilitation program compared with a traditional centre-based program (Study 4, Paper 4). A mixed methods study was also conducted to determine patient experiences and perspectives related to a heart failure telerehabilitation program (Study 5, Paper 5).Based on the systematic review of 11 studies, telerehabilitation appears to be a promising alternative to traditional centre-based programs in patients with cardiopulmonary diseases. In particular, telerehabilitation has been shown to improve exercise capacity and quality of life in these patient groups and has higher adherence rates compared with traditional centre-based programs.iii However, suitable outcome measures that can be administered via telerehabilitation are required. A possible outcome measure is the TUGT, which is a quick and easy-to-administer functional test.However prior to using the TUGT as an outcome measure in telerehabilitation studies, it was first important to validate its use in both face-to-face and telerehabilitation environments. The TUGT demonstrated excellent test-retest reliability in patients with C...

During hand grip operations, the fatigability of the local muscle determines the antifatigue capacity and influences the risk of injury of the workers. This study proposes a new hand grip subject‐specific fatigability indicator using a parameter identification technique from a physiologically based muscle fatigue model. Experimental measurements were conducted in a laboratorial fatiguing operation with a fixed external load (5 kg) under a static posture. Sixty participants (30 males and 30 females) participated in the experiment. Subject‐specific hand muscle fatigue rates (k) were identified by performing regressions of the muscle strength during time intervals using the muscle fatigue model. The majority (46/60) of the goodness of fit statistics (R2) was over 0.70, which indicates the validity of using the fatigue rate (k) as a hand grip fatigability indicator. Individual differences in the hand grip fatigue rate (k) were substantial, ranging from 0.14 to 2.57 min−1 with a coefficient of variation of 59.0%. The gender effect and body mass index did not exhibit significant influences on the hand grip muscle fatigue rates (k).
