“…However, no studies were found which investigated the effects of various sources of outcome values for the assessment of strength of the UE and trunk muscular groups and their measurement properties in subjects with stroke [11]. Furthermore, variations regarding the number of trials have been reported in the literature [16][17][18][19]. For example, if only one assessment trial proved to be reliable, this would rapidly improve the applicability and feasibility of dynamometry for the assessment of strength, considering that valuable time would be saved, besides avoiding muscular and general fatigue [16,17].…”

“…Coldham et al [16] showed that only one trial of maximal grip strength was as reliable as the mean of three trials, and had also the advantage of being less tiring, when measuring strength of subjects following carpal tunnel decompression, flexor tendon repair, and even in asymptomatic subjects. Kennedy et al [17] investigated the test-retest reliability of grip strength in subjects with rheumatoid arthritis, and also reported that the use of only one trial provided similar values and it was as reliable as the mean of three trials. Abizanda the dynamometer, only one trial was sufficient.…”

“…All patients gave written informed consent to participate in the study. A previous reliability study 14 reported requiring a sample size of 19 if looking for true reliability exceeding an intra-class correlation coefficient (ICC) of 0.7. Kennedy et al 17 based their sample size of 24 participants on a target intra-class correlation coefficient (ICC) of >0.90, with 80% power and a significance level of p > 0.05.…”

“…16 In patients with hand OA, where each trial may trigger pain, recovery periods may need to be longer. However, recent studies 14,17 have indicated that a single trial of grip strength may be as reliable as the average of three trials. Patients with symptomatic OA first CMCJ may fatigue quicker and experience pain even at rest, therefore using fewer trials would be desirable.…”

Objectives: To compare pain, patient preference and the test-retest reliability between the Jamar dynamometer and the MIE myometer using a single trial of pinch strength in patients with first carpometacarpal joint (CMCJ) osteoarthritis (OA). Methods: A prospective, within patient, repeated measures design was used. A digital strain gauge torsion dynamometer (MIE) and a hydraulic dynamometer (Jamar) were used to measure tripod pinch strength using a single trial on two occasions. Pain was assessed after each trial of pinch strength using a numeric pain rating scale (NRPS). Patients were asked which instrument they preferred and why. The test-retest reliability of each instrument was calculated using an intra-class correlation coefficient. Results: Thirty-eight patients with a confirmed diagnosis of OA of the CMCJ referred to hand therapy took part in the study. There were no statistically significant differences in mean pain scores (NPRS 0-10) between the Jamar and the MIE (mean difference 0.3, p ¼ 0.24, 95% CI À0.214 to 0.846). There was no clear preference for one or the other instrument. Test-retest reliability using a single trial of pinch strength was excellent with both instruments (MIE, ICC ¼ 0.914; Jamar ICC ¼ 0.891). Conclusions: Although patients had a slightly lower pain score with the MIE these differences were not statistically significant and an almost equal number of patients preferred each instrument. The use of a single trial of pinch strength still confers high reliability when using the MIE and Jamar justifying the continued use of both instruments for clinical practice and research

“…Participants will be encouraged to grasp strongly without feeling pain or discomfort (39). In patients with hand RA, a single trial is recommended to avoid discomfort and burden from subsequent measures (40). The threshold for the MCID for power grip is estimated between 5-6 Kg (41).…”

• Background: Therapeutic exercise is a safe and cost-effective approach to alleviate hand rheumatoid arthritis (RA) related symptoms. This study aims to investigate the differences in self-management between a smartphone app (CareHand), using hand exercises and educational advices, compared with a standard approach, on hand overall function, pain intensity, stiffness, and grip and pinch strength in patients with hand RA.• Methods: The project is a prospective, longitudinal, superiority, randomized controlled trial. Fifty-eight participants with hand RA will be randomly assigned into an experimental group (CareHand app) or a control group (conventional treatment). Control intervention involves a paper sheet with exercises and recommendations, and the experimental group includes the use of a smartphone app, which provides individualized exercise programmes, self-management and educational strategies to promote adherence to treatment. Both intervention protocols will last for 3 months. The principal investigator will conduct an educational session at baseline for all participants. Primary outcome comprises the overall hand function, assessed with the Michigan Hand Outcome Questionnaire (MHQ). Secondary outcomes include self-reported functional ability with the Quick DASH questionnaire, self-reported pain intensity and morning stiffness using a Visual Analogue Scale (VAS), and hand grip and pinch strength (dynamometer). Outcome measures will be collected at baseline, and at 1 month and 3-month follow-up.• Discussion: This study will evaluate the effectiveness of a telerehabilitation tool, which uses exercise and self-management strategies, compared to a conventional approach, in patients with hand RA. The smartphone app will allow to monitor the patient´s status, and to enhance patient-therapist communication. Some limitations may be related to the short follow-up duration and the lack of evaluation of psychosocial factors. Overall, this new way of promoting long-term effects in patients with a chronic rheumatic disease could be feasible and easy to implement in daily life clinical practice and current musculoskeletal care.• Trial registration: ClinicalTrials.gov Identifier: NCT04263974.
