“…We found that grip strength assessment with the Jamar dynamometer and the Vigorimeter demonstrated comparable validity and reliability, as suggested in prior studies (Mathiowetz et al, 1984;Solgaard et al, 1984;Jones et al, 1991;Bellace et al, 2000;Merkies et al, 2000;Rosen et al, 2000;Mathiowetz, 2002; Smidt et al, 2002;Bohannon and Schaubert, 2005;Guerra and Amaral, 2009;Lindstrom-Hazel et al, 2009;Espana-Romero et al 2010). Only one other study, in healthy children, directly compared reliability aspects of the Vigorimeter and a Jamar-like tool (Lode dynamometer) and showed significantly lower intra-class correlation coefficients for the Vigorimeter (Molenaar et al, 2008).…”

“…The Jamar dynamometer and the Vigorimeter are the most commonly used tools to assess grip strength in immune-mediated neuropathy trials (Hahn et al, 1996;Federico et al, 2000;Hughes et al, 2001;Hughes et al, 2008). Both have showed good scientific properties (Mathiowetz et al, 1984;Solgaard et al, 1984;Jones et al, 1991;Bellace et al, 2000;Merkies et al, 2000;Rosen et al, 2000;Mathiowetz, 2002;Smidt et al, 2002;Bohannon and Schaubert, 2005;Guerra and Amaral, 2009;Lindstrom-Hazel et al, 2009;Espana-Romero et al 2010), although a clinimetric comparison between these measures has never been performed in immune-mediated neuropathies (Merkies and Lauria, 2006). If one of these devices is a superior measure of handgrip strength, it could be used as a standard for future clinical trials, thereby increasing precision, reliability, and responsiveness within a treatment trial, and allowing comparability between therapeutic trials.…”

The Jamar dynamometer and Vigorimeter have been used to assess grip strength in immune-mediated neuropathies, but have never been compared to each other. Therefore, we performed a comparison study between these two devices in patients with immune-mediated neuropathies. Grip strength data were collected in 102 cross-sectional stable and 163 longitudinal (new diagnoses or changing condition) patients with Guillain-Barré syndrome (GBS), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), gammopathy-related polyneuropathy (MGUSP), and multifocal motor neuropathy (MMN). Stable patients were assessed twice (validity/reliability studies). Longitudinal patients were assessed 3-5 times during 1 year. Responsiveness comparison between the two tools was examined using combined anchor-/distribution-based minimum clinically important difference (MCID) techniques. Patients were asked to indicate their preference for the Jamar or Vigorimeter. Both tools correlated highly with each other (ρ = 0.86, p < 0.0001) and showed good intra-class correlation coefficients (Jamar [Right/Left hands]: ICC 0.997/0.96; Vigori: ICC 0.95/0.98). Meaningful changes were comparable between the two instruments, being higher in GBS compared to CIDP patients. In MGUSP/MMN poor responsiveness was seen. Significant more patients preferred the Vigorimeter. In conclusion, validity, reliability, and responsiveness aspects were comparable between the Jamar dynamometer and Vigorimeter. However, based on patients' preference, the Vigorimeter is recommended in future studies in immune-mediated neuropathies.

“…These devices are easy for therapists to use (Bohannon, 1999), and readings by different raters have been proven reliable when researchers follow the American Society of Hand Therapists (ASHT) standard protocol and raters receive training in reading the gauges accurately (Lindstrom-Hazel, Kratt, & Bix, 2009;Sebastin, Lim, Bee, Wong, & Methil, 2005). These interrater reliability studies support the use of students, nonhealth care professionals, and therapists to collect the strength measurements, but examination of the validity of the norms used for comparison regarding geographic relevancy is necessary.…”

“…In an earlier published study, four student raters in six different "teams" who were trained by the same procedure for administration of the grip and pinch testing were found to have an ICC that ranged from .996 to .998 for the Jamar dynamometer; ICC scores ranged from .951 to .993 for key pinch and from .944 to .988 for 3-point pinch readings for those six teams of student data collectors (Lindstrom-Hazel et al, 2009). …”

“…Intrarater reliability and validity for determining hand and pinch grip strength, using a dynamometer, are very high if the mean of three trials and a standardized test position are used. 30,31 Physical examination tests and measures revealed several impairments of body structures and function (Table 1). Visual observation of the left index finger PIP showed signs of peri-articular edema (Fig.…”

Finger injuries are common and can greatly affect a musician's quality of life. A 55-year-old man, who had injured the proximal interphalangeal joint of the left index finger 6 months prior to any intervention, was treated with a manual therapy approach incorporating instrument-assisted soft tissue mobilization (IASTM). Initial examination findings included self-reported pain and functional limitations and physical impairments that significantly impeded his ability to play the acoustic guitar. He was treated once a week for 6 weeks with IASTM, joint mobilization, therapeutic exercise, and ice massage. Additionally, a home exercise program and self-care instructions were provided. The patient gained positive outcomes with improvements in pain (Numerical Pain Rating Scale while playing the guitar: initial 5/10, discharge 1/10) and function (Disability Arm Shoulder Hand Sports-Performing Arts Optional Module: initial 75; discharge 6.25), each reaching a minimum clinically important difference. Importantly, he was able to play the guitar with minimal to no pain as desired. Physical measures also improved, including an immediate gain in finger range of motion with IASTM alone. Manual therapy approaches integrating IASTM may provide an effective conservative treatment strategy for patients with finger/hand conditions in the performing arts and other patient populations.
