“…However, the findings of this study appear to be consistent with those from other studies that assessed the reliability of hand-held dynamometers. Regarding intra-rater reliability, ICC values for shoulder abduction ranged from 0.87 to 0.98 [ 25 ] or 0.83 to 0.85 [ 26 ] and the minimal detectable change (MDC) ranged from 15% to 35%, whereas ICC values for shoulder adduction ranged from 0.77 to 0.98 and an MDC of 51% [ 25 ]. Similarly, for hip adduction and abduction, ICC values ranged from 0.94 to 0.95 [ 27 ], or 0.97 to 0.98 [ 28 ], or 0.63 to 0.89 [ 26 ], and the SEM ranged from 2.3 to 6.8 [ 27 ].…”

Despite the fact that the positions used in the current study were functional, influenced by gravity, and without stabilization, in contrast to previous studies, the results of this study are comparable or in some cases, even better.…”

Background: Pole dancing is a physically demanding sport that combines dance and acrobatic movements on a vertical pole. Despite its highly growing popularity, there is currently limited research in the field. The aim of this study was to create and evaluate a strength assessment protocol for athletes in pole dancing, with a specific focus on functional positions on the pole. Methods: Thirty-two female pole dancing athletes participated in this study. Maximal voluntary isometric contractions (MVIC) were measured at three different sport-specific positions on the pole (shoulder abduction and adduction, and hip adduction), on two separate days (test and re-test) with a five to seven day interval between them. A hand-held dynamometer (Activ5- Activbody) stabilized on the pole was used for this study. Results: The intra-session reliability was good to excellent for all sports-specific positions and for both sides of the body, across all different movements (ICC = 0.837–0.960, SEM = 5.02Kg-2.24Kg, and SDD = 27.46%-14.92%). Slightly better results were found regarding inter-session reliability (ICC = 0.927–0.970, SEM = 3.72Kg-1.97Kg, and SDD = 22.86%-15.19%). There was not a statistically significant difference between the MVICs between the left and right or dominant and non-dominant side in shoulder abduction (p = 0.105) and hip adduction (p = 0.282), in contrast to shoulder adduction (p = 0.00). Conclusion: The strength assessment protocol developed in the current study has proven to be a reliable and functional tool, with the potential for utilization in clinical practice as part of objective strength testing. Further studies are needed in order to expand the protocol to other muscle groups and positions and to generalize the results in all pole dancing populations such as male athletes.

“…The EasyForce dynamometer can be considered a reliable tool for assessing knee extension strength. 58 Isometric handgrip strength: will be performed using the Jamar Smart digital hand dynamometer (Patterson Medical, Warrenville, IL, USA) at baseline and at follow-up at 4 months and 12 months and will be measured as the highest score out of three attempts. The Jamar Smart digital hand dynamometer has been validated and has proven excellent inter-instrument reliability and strong concurrent validity.…”

Background Despite the great individual and societal burden associated with multimorbidity, little is known about how to effectively manage it. Objective The aim of this multicenter randomized controlled trial (RCT) is to investigate the 12-month effects of a personalized exercise therapy and self-management support program in addition to usual care in people with multimorbidity. Design This is a protocol for a pragmatic, parallel-group (1:1 ratio), superiority RCT conducted at five intervention sites (two hospitals, a private practice physiotherapy clinic and two municipal rehabilitation centers) in Region Zealand, Denmark. A total of 228 persons with multimorbidity aged 18 years or older, will be randomly allocated to one of two groups. Both groups will receive usual care, defined as routine care for multimorbidity at the discretion of the treating doctor, while the intervention group will also participate in a 12-week exercise therapy and self-management support program tailored to people with multimorbidity at one of the intervention sites. The primary outcome will be the between-group difference in change in EQ-5D-5L from baseline to the follow-up at 12 months. Secondary outcomes include objectively-measured physical function and physical activity, inflammatory markers, disease and treatment burden, anxiety, depression, stress, sleep, pain and other self-reported parameters. In parallel with the RCT, an observational cohort will follow persons aged ≥18 years with multimorbidity not adhering to all eligibility criteria, as well as people fulfilling all eligibility criteria, but unwilling to participate in the RCT. This study was approved by the Regional Committee on Health Research Ethics for Region Zealand (SJ-857) and results will be communicated in scientific papers, at relevant conferences and to a broader audience. Discussion Exercise therapy and self-management support is safe and effective in people with single conditions. However, it is still unclear whether this holds true for individuals with multimorbidity. This pragmatic, multicenter RCT will provide high-quality evidence on the benefits and harms of exercise therapy and self-management support and, if the results support it, lead to the development of a plan for implementation in clinical practice.

“…Other than muscle mass, muscle strength should also be evaluated for sarcopenia diagnosis, albeit guidelines only suggest sit-to-stand tests and hand grip strength test, with the latter showing wide variability among subjects [ 9 ]. In this context, Trajković et al [ 12 ] investigated the interrater and intra-rater reliability of a belt stabilized handheld dynamometer measuring isometric strength of 23 young adults in knee extension, knee flection, hip adduction, hip abduction, shoulder internal rotation, and shoulder abduction. The results supported the good to high inter- and intra-rater reliability with an intraclass correlation coefficient range of 0.63–0.91.…”
