OBJECTIVE
Little is known about how specific radiographic features are related to hand strength in osteoarthritis (OA). This study examined associations of radiographic variables with pinch and grip strength among individuals with radiographic hand OA.
METHODS
Participants (n = 700, 80% female, mean age 69 years) were part of a study on the genetics of generalized OA. All had bilateral radiographic hand OA. Linear models were used to examine associations of grip and pinch strength with 1) OA in joint groups (proximal interphalangeal, metacarpophalangeal [MCP], carpometacarpal [CMC]), 2) OA in rays (first through fifth), and 3) summed Kellgren/Lawrence (K/L) grades for severity of OA in all joints. Adjusted models controlled for age, sex, hand pain, chondrocalcinosis, and hand hypermobility. Mixed models accounted for clustering within families.
RESULTS
In bivariate analyses, all joint groups, all rays, and total summed K/L grades were significantly negatively associated with grip and pinch strength (P < 0.05). In adjusted models, the only joint group significantly associated with grip strength was the CMCs, and only OA in the MCP joint was significantly associated with pinch strength (P < 0.05). The only ray significantly associated with grip strength (P < 0.05) was ray 1, and no individual rays were significantly associated with pinch strength. A higher summed K/L grade was significantly associated with both lower grip strength and lower pinch strength.
CONCLUSION
Among individuals with radiographic hand OA, increasing radiographic severity is associated with reduced grip and pinch strength, even when controlling for self-reported pain. Individuals with radiographic OA in specific locations (CMC joints, MCP joints, and ray 1) may be at particular risk for reduced hand strength.

Information regarding the relationship between the degree of hand function among the elderly as measured by traditional assessments and the ability to manipulate touchscreens is lacking. This study aimed to examine the correlation between the ability to manipulate a touchscreen device, as assessed using the touchscreen assessment tool (TATOO) (University of Haifa, Israel & Universetiy of Bologna, Italy), and hand strength and manual dexterity among independent community-living older individuals. Thirty-four community-living older adults (average age 79.4 ± 6.7 years) participated in single-session assessments lasting 45 min each. The assessment included hand strength measurement using the manual hand dynamometry and hydraulic pinch gauge, a functional dexterity test (FDT), and TATOO. No significant correlations were observed between most of the TATOO items (22 out of 26) and handgrip strength, pinch strength, and FDT results. Moderately significant correlations were demonstrated between the number of drag attempts in the "Drag to different directions" task and handgrip strength and manual dexterity ( value: -0.39, value: 0.02; value: 0.36, value: 0.04, respectively). In addition, a moderately significant correlation was noted between the number of double taps and manual dexterity ( value: 0.32, value: 0.07). These results indicate that more complex gestures that require greater accuracy (dragging task) or rapid movements (double tapping) are related to hand strength and manual dexterity. These results suggest that the manual gestures necessary for touchscreen operation entail unique and specific capabilities that are generally not captured by traditional tools. The clinical implication is that the hand function assessment toolbox should be expanded. Tools such as the TATOO should be used to capture skills required for touchscreen manipulation in the context of the modern digital milieu.

Patients with neurogenic thoracic outlet syndrome report pain and upper-limb weakness. They complain about weakness occurring on the entire upper-limb, especially at the hand and the shoulder levels. Hydraulic dynamometers can reliably assess the strength of the hand, and isokinetic shoulder testing can provide accurate and reliable evaluations of the rotators strength. Yet, isokinetic proximal assessment needs expensive tools, whereas hydraulic hand dynamometers are cheap and easy to use. We aimed to assess the correlation between the isokinetic shoulder strength and the hand grip and the key pinch strength. The grip strength was evaluated with a hydraulic hand dynamometer and the key pinch with a pinch gauge. Isokinetic rotators strength tests were performed using a Humac Norm® dynamometer at 60 and 180°/s. One-hundred and thirty patients had been included, 72% of women, mean age of 39.8 ± 9.5. Symptomatic hands presented a strength deficit of 12.2% on the grip ( < 0.0001) and 10% on the key pinch ( = 0.01). Isokinetic strength was lower on the symptomatic shoulders at 60 and 180°/s concerning medial rotators [-10.3 and -8.8%, respectively ( = 0.02)] and lateral rotators [-10.8 and -10%, respectively ( = 0.04 and = 0.03)]. There was a moderate correlation between the grip strength of the symptomatic upper-limbs and the isokinetic rotators strength ( < 0.001). The key pinch strength was moderately correlated to the isokinetic medial and lateral rotators strength at 60°/s ( < 0.001). Hand dynamometers could prove useful during medical consultations or in outpatient management to assess upper-limb overall weakness, but isokinetic measurement remains the gold standard for a precise evaluation.

BACKGROUND
Carpal tunnel syndrome (CTS) is the most common peripheral entrapment neuropathy with a high morbidity and healthcare-related costs. Currently there is no consensus about the best treatment option. The purpose of this prospective cohort study conducted at a single institution was to evaluate the clinical outcomes and patient satisfaction following a mini-open carpal tunnel release for idiopathic CTS.
METHODS
A total of 72 patients (53 female and 19 male patients; mean age, 57.8±15.3 years; range, 24-94 years) had a mini-open carpal tunnel release performed by a single senior surgeon between June 2015 and June 2016. The patients were evaluated preoperatively, and at 3 and 12 months post-intervention. At every follow-up, the Boston Carpal Tunnel Syndrome Questionnaire (BCTSQ) and visual analogue scale (VAS) scores for pain and satisfaction were completed. Digital sensibility (using Semmes- Weinstein monofilaments) was assessed and pinch and grip strengths were measured.
RESULTS
Statistically significant and clinically relevant improvement was found in terms of digital sensibility, grip and pinch strength (except for 2-point pinch), BCTSQ scores and pain scores. The complication rate was minimal, and no major complications occurred. Two patients experienced recurrence. The availability of follow-up records (including patient-reported outcomes, BCTSQ and VAS scores, and the complication rate) at 1-year post-intervention varied between 69% and 74% (50-53 patients) depending on which parameter was assessed. Patient satisfaction was high (mean, 80.9±26.0; range, 0-100).
CONCLUSIONS
This study demonstrates that mini-incision carpal tunnel release is clinically effective in the short and long term.

UNLABELLED
Arthroscopic partial trapeziectomy with suture-button suspensionplasty was developed for the surgical treatment of thumb carpometacarpal arthritis. However, the relationship between clinical results and radiographic evidence is unclear.
METHODS
The authors retrospectively reviewed 33 consecutive patients who underwent arthroscopic partial trapeziectomy with suture-button suspensionplasty for thumb carpometacarpal arthritis between 2016 and 2021. Clinical and radiographic outcomes were recorded, and the correlations between them were evaluated.
RESULTS
The average patient age at surgery was 69 years. Patient radiologic evidence was Eaton stage Ⅱ in three thumbs, Ⅲ in 25 thumbs, and Ⅳ in five thumbs. The average trapezial space ratio (TSR) was 0.36 immediately after the operation but declined to 0.32 after 6 months. In contrast, the average joint subluxation was reduced to 0.005 immediately after the operation compared with 0.28 before, and was maintained at 0.04 at final follow-up. A statically significant correlation was detected between grip strength and TSR ( = 0.03), and between pinch strength and TSR ( = 0.02). A significant correlation was detected between TSR and trapezium height ( = 0.0215), which remained after partial trapeziectomy. No correlation was detected between rope position and other clinical or radiographic scores.
CONCLUSIONS
Suture-button can have an effect on the medialization of the first metacarpal base. Excessive trapeziectomy can result in functional deficiency of the thumb through metacarpal subsidence, which potentially causes loss of grip and pinch strength.

The Journal of International Medical... Nov 2018The study aim was to examine the hand function (hand strength and dexterity) and intervention effects of training in adults with Prader-Willi syndrome (PWS).
OBJECTIVE
The study aim was to examine the hand function (hand strength and dexterity) and intervention effects of training in adults with Prader-Willi syndrome (PWS).
METHODS
Six adults with PWS (two females; mean age 26.14 years) underwent hand muscle strength and dexterity training for 3 months (2 hours per week). The following hand function tests were performed pre- and post-intervention: (1) hand grip, lateral pinch, and tip pinch hand strength tests, (2) the Box and Block test (BBT) for gross manual dexterity and (3) the Purdue Pegboard test for finger dexterity.
RESULTS
Before treatment, all subjects showed lower hand grip, lateral pinch, tip pinch strength, and poorer manual/finger dexterity relative to healthy adults. After training, hand function scores improved on many test items, but only the left hand tip pinch and the right hand BBT performance showed significant improvements.
CONCLUSIONS
All subjects showed lower hand strength and poorer manual/finger dexterity compared with healthy adults; this should be considered during physical training programs. Owing to limitations in the intervention intensity and possible subject behavioral deficits, further research is needed to clarify the effects of this intervention on hand function in PWS patients.

The Journal of International Medical... Oct 2020To evaluate the effectiveness and safety of allogeneic tendons for functional reconstruction of severe hand injuries.
OBJECTIVE
To evaluate the effectiveness and safety of allogeneic tendons for functional reconstruction of severe hand injuries.
METHODS
From August 2007 to July 2014, we performed functional reconstruction with tendon allografts for severe hand injuries affecting two or more tendons. At the final follow-up, we assessed total active motion (TAM); pincer pinch strength; grip strength; Disabilities of the Arm, Shoulder, and Hand (DASH) score; degree of satisfaction; and adhesion. We measured the white blood cell count, C-reactive protein concentration, erythrocyte sedimentation rate, total T-cell count, and CD4T/CD8T ratio to evaluate the immune response and check for infection.
RESULTS
Ten patients received 26 allogeneic tendons to reconstruct hand function. The average follow-up period was 50.0 months (range, 24-82 months). The TAM was 126.4° (12°-253°), pincer pinch strength was 0.83 kg (0-4.5 kg), and grip strength was 13.69 kg (4-41.5 kg). The DASH score was 14.25 (3.3-30.8), and seven and three patients were satisfied and partially satisfied, respectively. One patient developed tendon adhesion. All immune and infectious parameters were within the reference range.
CONCLUSION
Functional reconstruction using allogeneic tendons for severe hand injuries with multiple tendon defects was effective and safe; however, more research is needed.

BACKGROUND
The relationship between mild cognitive impairment (MCI) and pinch strength in patients with cardiovascular disease is unclear. The purpose of the present study was to examine the associations among MCI and pinch strength and to determine a pinch strength cut-off value for use in the assessment of MCI.
METHODS
We conducted a cross-sectional study of 135 patients with cardiovascular disease but without probable dementia. MCI was estimated with the Japanese version of the Montreal Cognitive Assessment. We classified patients into the normal cognitive group and MCI group and compared their clinical characteristics, handgrip strength, and pinch strength. The relation between MCI and pinch strength was clarified with logistic regression analysis, and the cut-off value for three-fingered pinch strength was determined by receiver operating characteristic curve analysis.
RESULTS
The incidence of MCI was 37.0 %. Significant differences between the two groups were identified for age, body mass index, hemoglobin, estimated glomerular filtration rate, albumin, dyslipidemia, use of nitrates, educational background, handgrip strength, and pinch strength. After multivariate analysis, three-fingered pinch strength was significantly associated with MCI (odds ratio 0.77, p= 0.02). The cut-off value of three-fingered pinch strength for predicting MCI was 6.75 kgf (area under the curve = 0.71; p< 0.001).
CONCLUSIONS
Pinch strength was one independent factor significantly associated with MCI in patients with cardiovascular disease. The determination of a cut-off value for three-fingered pinch strength that can predict MCI may be one important factor in the early screening for MCI in the daily clinical setting.

OBJECTIVE
The aim of this study was to demonstrate a new robotic technique for the fixation of the fracture of the hook of hamate.
METHODS
In this retrospective study, six patients who had undergone treatment of the hook of hamate fracture with a new technique using robot navigation were included. Patients were evaluated postoperatively with flexion - extension and radial-ulnar range of wrist motion, and were measured using a goniometer. Grip strength and pinch strength were measured and compared with the contralateral wrist at the final follow-up. The Visual Analog Scale (VAS) and the Mayo Wrist Score were used to evaluate and record the recovery outcome of the wrist.
RESULTS
Primarily, healing was achieved at 12.3 weeks postoperatively. At the final follow-up (5-22 months, average 13.1 months) the VAS score of the wrist was an average of 0.3 (0-2); the mean radial-ulnar deviation was 64.7°; the average of the flexion and extension range of motion was 141.9°; the average grip strength was 40.9 Kg; the average pinch strength was 11.8 Kg and the average Mayo Wrist Score was 95.8.
CONCLUSION
This study has shown us that treatment of nondisplaced or minimal displaced fractures of the hook of the hamate with robot navigation is a viable technique with satisfactory clinical and radiological results.

OBJECTIVE
Little is known about the frequency and severity of hand dysfunction in individuals with multiple sclerosis (MS). Hence, we sought to determine the extent that quantitative tests of hand function detect changes over time, evaluate their relationship to global disability measures, and identify predictors of hand function.
METHODS
One-hundred and forty-seven individuals with MS were included (96 women, 84 relapsing-remitting MS [RRMS]) along with 35 age-and-sex matched controls. Quantitative tests of hand function (grip strength, pinch strength, 9 hole peg test [9HPT], finger tapping) and leg strength were acquired and normalized to age and sex. Expanded Disability Status Scale (EDSS) and timed 25 foot walk were also obtained. Spearman correlations, multivariate regression models and mixed effects linear regression were used for analysis.
RESULTS
Our cohort had an EDSS of 3.6 ± 2.2 (median ± SD) and age 44.6 ± 11.9 years. Follow up time was up to 5 years. At baseline, 14/63 individuals with progressive MS (PMS) required more than twice as much time to complete the 9HPT using their dominant hand, compared to controls. Similarly, 11 individuals with PMS had less than 50% of grip strength and 6 had less than 50% of pinch strength, compared to controls. Additionally, 7 individuals with PMS were found to be at least 50% slower than controls in finger tapping. Over two years, 27/85 individuals with MS had more than 20% worsening in their 9HPT results from baseline (17 RRMS, 10 PMS) and 37/74 (20 RRMS, 17 PMS) had more than 20% worsening in their grip strength compared to baseline.
CONCLUSIONS
Hand function is commonly impaired in individuals with MS. Assessing hand dysfunction with dynamometry and the 9HPT could help improve the precision of detecting changes in hand function over time in MS, and may be more sensitive in detecting changes in PMS. These quantitative tests may be useful as outcome measures in clinical trials using neuroprotective or reparative therapies and rehabilitative interventions.
