Clinical and electrophysiological examination of pinch strength in patients with amyotrophic lateral sclerosis.

The split-hand concept has highlighted the preferential wasting of the thenar side of the hand in amyotrophic lateral sclerosis (ALS). Our objective is to re-explore pinch grip strength to assess whether it has the potential to be a practical biomarker of ALS. We measured different pinch grip strengths (thumb, index, and fifth) using a pinch gauge from both hands of 54 ALS patients and correlated this with the Medical Research Council (MRC) score, the upper-limb component of the revised ALS Functional Rating Scale - Revised (ALSFRS-R) score, and compound muscle action potentials (CMAPs) that comprise the split-hand index. Pinch grip strength using any of the three fingers showed a positive correlation with its corresponding CMAP, MRC grading, and upper-limb ALSFRS-R score. The thumb pinch showed the strongest correlation with the split-hand index and MRC grading. Pinch grip strength test using a simple gauge deserves further study as a potentially practical biomarker of ALS.

Validation of a new hand function outcome measure in individuals with Charcot-Marie-Tooth disease.

The symptomatology of Charcot-Marie-Tooth (CMT) disease mainly involves the feet and the hands. To date, there is no consensus on how to evaluate hand function in CMT. The aim of this study is to correlate the data of the engineered glove Hand Test System (HTS) with specific tests and the CMT examination score (CMTES). We analyzed 45 patients with the diagnosis of CMT using HTS, which measures the hand dexterity by specific sequences performed at maximum velocity. We completed the evaluation with the CMTES, tripod pinch and hand grip strength tested by a dynamometer, thumb opposition test (TOT), and Sollerman Hand function test (SHFT), and we conducted a test-retest with 20 normal subjects. Finger tapping (FT) and index-medium-ring-little (IMRL) sequence showed a significant correlation with CMTES (FT: dominant hand (DH): P = .036; non-dominant hand (NDH): P = .033; IMRL: DH: P = .009; NDH: P = .046). TOT correlated with CMTES significantly in both hands (P < .0001). tripod pinch showed a statistically significant correlation with CMTES (DH: P = .002; NDH: P = .005). Correlation between the hand grip and CMTES was significant only in DH (DH: P = .002). SHFT had a significant correlation with the CMTES (DH: P = .002). Test-retest showed a good reliability. HTS parameters correlate with CMTES confirming that this tool is sensitive to the hand deficits. In conclusion, we can state that HTS is a good, simple to use, and objective instrument to evaluate the hand function of CMT patients, but more studies on responsiveness and sensitivity are needed.

Is Boston questionnaire an alternative to electromyography for evaluation of the surgical outcome for carpal tunnel syndrome?

Objectives This study aims to identify the optimal follow-up method for evaluation of the surgical outcome for carpal tunnel syndrome (CTS).Patients and methods Between January 2006 and December 2010, 61 hands of a total of 46 patients (7 males, 39 females; mean age 56.0±10.4 years; range, 20 to 71 years) with a diagnosis of CTS were retrospectively analyzed. All operations were performed by a single surgeon with a mini-incision distal to the transverse carpal ligament. At a mean follow-up of seven years after surgery, electromyography (EMG) was repeated for all patients. The Boston Carpal Tunnel Questionnaire (BCTQ), Boston Symptom Severity Scale, Boston Functional Status Scale, palmar pinch strength, grip strength, and EMG of the patients were compared before and after surgery.Results The mean follow-up was 84±10 (range, 72 to 104) months. There were significant improvements in the Boston Symptom and Functional Scale scores postoperatively, as well as in the grip and pinch strength. After surgery, EMG findings improved in 83.6% of the patients. However, there was no significant correlation between pre- and postoperative Boston Symptom Severity Scale scores, functional status, pinch and grip strengths, and pre- and postoperative EMG results.ConclusionOur study results demonstrate that the symptom severity and functional status scores of the BCTQ are favorable, and this tool is reliable and easy-to-apply for the diagnosis and follow-up of CTS surgeries.

A Cross Sectional Study on Middle Finger Tip Pinch, Ring Finger Tip Pinch, Little Finger Tip Pinch Strengths : The Correlations with Anthropometric Variables in North Indian Population

Introduction: Pinch strength in addition to handgrip strength is considered an important factor in the assessment of proper hand muscle function. Various parameters like nutritional status, physical activities and muscle pathologies can affect the overall gripping capabilities of the fingers .The unique abilities of opposition in human hand is because of the distinct articular surfaces in the miniature bones and intrinsic muscles of the hand. Due to fine neuromuscular coordination and sensory perception in the digits, firm grasping abilities and in the hand pinches have developed. These grasps can be very useful for sensory and motor capabilities of the hand specially in sports like cricket, baseball and volleyball. AIM: To generate data for middle finger tip pinch, ring finger tip pinch, little finger tip pinch strengths and to evaluate their correlations with other anthropometric indices. Materials and Methods: Four hundred and fifty healthy young adult individuals were selected for the study. A pinch gauze was used to measure pinch grip strengths in both the sides. Pearson’s correlation test and independent t-tests were used. SPSS Version 20 was used for statistical analysis. Result: Mean age of the population was 22 years and all the subjects were males. Pinch grip strength in all the pinches were found to be greater in dominant side than non dominant side (p<0.001). There was significant association between middle finger tip pinch and anthropometric indices. No statistically significant correlation of little finger tip pinch with waist circumference, waist to hip ratio and BMI was observed. Conclusion: The analysis provides normative data for pinch grip strengths and their correlation with other anthropometric indices in adult North Indian population.

Grip strength and pen pressure are not key contributors to handwriting difficulties in children with developmental coordination disorder

Introduction Children with developmental coordination disorder have significant difficulties with handwriting. Factors such as hand grip strength and pen pressure are often assumed by clinicians to play a role, although empirical evidence is lacking. The aim of this study was to measure grip strength and pen pressure to examine their relationships with handwriting performance in children with developmental coordination disorder. Method Sixteen 8–14-year-old children with developmental coordination disorder were compared with 20 typically developing age- and gender-matched controls. Palmar, pinch and tripod grip strength were measured using hand dynamometers. The mean pressure exerted on a writing tablet by the pen was obtained during a handwriting task. Group comparisons were made and correlations conducted between grip strength and pen pressure and a range of handwriting product and process measures. Results There were no group differences on the three measures of grip strength. However, the developmental coordination disorder group exerted less pressure on the writing surface compared to typically developing peers. There were no significant correlations between grip strength or pen pressure and handwriting performance in children with developmental coordination disorder. Conclusion Clinicians should be cautious when using measures of grip strength or pen pressure to inform them about aspects of handwriting skill in children with developmental coordination disorder.

Evaluating hand performance and strength in children with high rates of smartphone usage: an observational study.

[Purpose] This study investigated the interaction effects between the levels of smartphone use and hand dominance on handgrip, pinch strengths, and functional hand performance in children. [Participants and Methods] A total of 60 children aged between 9 and 15 were assigned into two groups: Group A (high-frequency smartphone users) and Group B (low-frequency smartphone users). Use levels were determined according to the smartphone addiction scale-short version. A hand dynamometer and pinch gauge were used to measure handgrip and pinch strength respectively. Functions of the upper extremity and hand were scored using the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire. [Results] Group A participants had reduced measurements in hand grip and pinch strength, especially in the dominant hand. However, Quick Disabilities of the Arm, Shoulder, and Hand scores indicated that hand function was decreased in the dominant hand whether the child was a high- or low-frequency smartphone user. [Conclusion] Results indicated that high levels of smartphone use diminished hand and pinch-grip strengths as well as and hand function. That is, hand and pinch-grip strengths were reduced in the dominant hands of high-frequency smartphone users. However, hand functions were affected in the dominant hands among both high and low-level smartphone users.

Functional outcomes after flexor tendon repair of the hand.

This study aims to evaluate the hand function after flexor tendon repair (FTR) and to investigate factors associated with functional outcomes. Between January 2013 and September 2015, a total of 126 patients (84 males, 42 females; mean age 31 years; range, 15 to 62 years) who underwent FTR due to flexor tendon injuries (FTIs) were included. The hand function was assessed using the Jebsen Hand Function Test (JHFT) and Quick Disabilities of the Arm, Shoulder and Hand (Quick DASH) at three and six months following FTR. Of the patients, 94 (75%) and 72 (56%) completed the three-month and six-month assessment visits, respectively. A total of 65 patients (51.1%) had both three and six-month follow-up data. The patients regained a fair amount of power grip strength and more than half of their pinch grip strength compared to the unaffected hand. The results of assessment of hand function at activity and participation levels (JHFT and Quick DASH) showed slightly higher levels of disability. Of 41 patients who were employed prior to injury, 29 (71%) returned to work at six months after surgery. Zone IV injury and language barrier were associated with poor functional outcomes at six months. Our study results showed that the JHFT and Quick DASH scores of the patients were less than the established norms, although functional outcomes improved over time. Based on these results, we suggest that the presence of zone IV FTI and language barrier are associated with poor functional outcomes.

CMT AND NEUROPATHY: P.90Reduced power and manual dexterity have an effect on fine motor function in children with CMT1A

The Dubowitz neuromuscular service at Great Ormond Street Hospital for Children sees approximately 180 children per year with a diagnosis of Charcot-Marie-Tooth (CMT), the majority having type 1A. Routine physiotherapy assessment of these children includes measurement of grip strength by "Citec" myometry and manual dexterity using the 16-Peg Functional Dexterity Test (FDT). Fine motor function and daily living activities are evaluated using an adapted Pedi scale for CMT. The aim of this study was to evaluate whether the reduced power in grip strength and manual dexterity difficulties affect fine motor function. Normal myometry data was collected for gross, thumb and pinch grip strength in 4 age groups, 4-7, 7-10, 11-14 and 15-18, from 20 boys and 20 girls in each group. Handedness was not defined as there was no significant difference found when establishing normal ranges. The Citec myometer was chosen as it allows to measure the specific grips, selected as most frequently used in daily function. The independent measurement reduces problems of inter and intra-relater reliability. Normative values established by Gorgola in 2013 for the Functional Dexterity Test (FDT) were used. Measurements from the 40 children with CMT1A were compared to these normal values. Information included ethnicity, laxity, hand dominance and regular hand activities. Findings for the children with CMT show that 100% presented with reduced power and dexterity. This resulted in all children over the age of seven reporting fatigue with writing longer than 30 minutes, and 85% need assistance to fasten open ended zips, laces and use small buttons which is not found in the normal population By routinely assessing hand power and dexterity we have been able to better address issues of difficulty with writing in school and obtain increased support for activities of daily living; enabling children to perform to their maximum ability and increase their independence as reported by parents.

Scaphometacarpal Space and Postoperative Outcomes: A Systematic Review.

Background A common notion is that more complex techniques for treating trapeziometacarpal arthritis such as ligament reconstruction and tendon interposition (LRTI) better preserve the scaphometacarpal (SMC) space compared to a simple trapeziectomy and that this leads to superior functional outcomes. Purpose The purpose of this systematic review is to evaluate the relationship between scaphometacarpal space and objective outcomes such as grip and pinch strength as well as subjective patient-reported outcomes. Methods A systematic review of the literature was conducted according to PRISMA guidelines. Inclusion criteria were studies reporting SMC space and outcomes after surgery for carpometacarpal arthritis. The primary outcomes of these studies included any measure of postoperative scaphometacarpal space (trapezial height/trapezial index) as well as key pinch strength, grip strength, or lateral pinch strength. Studies that did not assess for association between SMC space and outcomes were excluded. Results Fourteen studies were included in this systematic review. Three (21.4%) studies found a statistically significant correlation between postoperative SMC space and postoperative pinch or grip strength. The correlation was weakly positive in one study (key pinch vs. scaphometacarpal space, r = 0.13), positive but unlisted in another (lateral pinch vs. trapezial ratio), and negative in the third study (key pinch vs. trapezial space ratio, r = -0.47). Conclusion Preservation of the SMC space postoperatively is not associated with postoperative outcomes. Further research is necessary to better characterize the importance of maintaining the SMC space in patients undergoing LRTI in order to substantiate claims by proponents of the procedure.

Percentage difference of hand dimensions and their correlation with hand grip and pinch strength among schoolchildren in Saudi Arabia.

The study aimed to assess the percentage difference of hand dimensions and their correlation with grip and pinch strength among school children in Saudi Arabia. Anthropometric measurements, hand dimensions, grip, and pinch strength measurements were obtained from 200 healthy schoolchildren in both genders aged 6-16 years. A Jamar electronic handgrip dynamometer was used to measure handgrip strength in kg. Pinch dynamometer was used to measure the two-point pinch strength, three-point pinch strength and lateral pinch strength in kg. Hand circumference was measured following hand arch at the maximum palm level. Hand span from the tip of the thumb to the tip of the little finger with the hand opened as broad as possible. Hand length from the tip of the middle finger to the midline of the distal wrist crease. Palm length from the distal wrist crease to the base of the middle finger. The percentage of difference of hand dimensions between both the genders was statistically significant. Both handgrip and pinch strength were significantly correlated with anthropometric measurements and hand dimensions. Body mass index had mild correlation with both handgrip strength and pinch strength (P < 0.05). Age, hand circumference, hand span, hand length and palm length had moderate to strong correlation with both grip and pinch strength (P < 0.01). The current study provides a source of perspective reference values in clinical settings for hand dimensions. The present study showed significant correlations with handgrip and pinch grip strengths among schoolchildren in Saudi Arabia.

Effects of dry needling on tendon-pulley architecture, pain and hand function in patients with trigger finger: a randomized controlled trial study.

[Purpose] The purpose of this study was to determine the effect of dry needling on tendon-pulley architecture, pain and hand function in patients with trigger finger. [Participants and Methods] A randomized controlled trial was conducted. Fifty eight patients having trigger finger were randomly assigned as either an experimental group that received a single session of dry needling over pulleyA1 and flexor tendon or a control group that received no intervention. Thickness of tendon-pulley, and pain-hand function (by disability arm-shoulder questionnaire score and pinch grip strength) were measured by a blinded assessor before and one week after intervention. [Results] The two way mixed ANOVA in the experimental group showed that the thickness of pulley-tendon decreased, pinch grip power increased and DASH questionnaire score was decreased in comparison to the control group. [Conclusion] This study results suggest that a single session of Dry Needling (DN) was effective in decreasing pain, DASH score, pulley-tendon thickness and improving pinch grip power in patients with trigger finger.

A comparative assessment of static muscular strength among female operative’s working in different handicraft occupations in India

An ergonomic assessment of static muscular strength like hand grip-and pinch strength in handicraft occupation was made. In total, 170 female participants were selected for the case-control study, out of which 120 handicraft and 50 office workers were examined as exposed and control groups. Their maximum static handgrip- and pinch strength were measured using hand and pinch dynamometers. We analyze our findings to indicate static muscular strength varies significantly due to repetitive use of hand tools. The decrement in pinch grip strength was evident due to long cycle repetitive pinching movements of distal phalanx during hand knotting and pearl drilling. Based on our results we propose the need for ergonomically designed hand tool interventions that may reduce the accumulation of loss in static muscle strength.

Measuring static muscular strength among female operatives: a cross-sectional comparison in different handicraft occupations

Purpose. Loss of static muscular strength is the most common work-related problem among handicraft workers involved in hand-intensive jobs. A cross-sectional comparative assessment was carried out to determine the muscular strength among workers involved in the manufacturing of three different crafts: weaving, hand block printing and imitation jewelry. Methods. 120 female operatives were selected, and digital grip dynamometers were used to measure their maximum hand grip and pinch strength. Results. Static muscular strength varies significantly among the different occupational groups of workers. The difference in grip strength in the right and left hands shows that exposure to hand tools for a prolonged period plays a vital role in muscle strength. These findings indicate that static muscular strength varies significantly due to repetitive use of hand tools. The observed values of muscle strength in the dominant hand were significantly lower in jewelry workers while block printing workers had the highest strength. Conclusion. The decrement in pinch grip strength was evident due to long-cycle repetitive pinching movements of the distal phalanx during hand knotting and pearl drilling. This study proposes the need for ergonomically designed hand tool interventions that may reduce the accumulation of loss in static muscle strength.

Measuring dexterity in the podiatrist population: a cross-sectional comparison of novice students and experienced podiatrists

BackgroundThere is no ‘gold-standard’ for the evaluation of dexterity for the health professional or podiatrist populations. This has resulted in a broad array of generalised tests to evaluate dexterity. Thus, the aim was to determine which objective generalised dexterity tests are best suited to evaluating dexterity in a podiatry student population.MethodsA cohort of Novice podiatry students and Experienced podiatrists were recruited and evaluated on a battery of dexterity tests selected to evaluate a variety of different elements. Group differences were evaluated statistically and regression undertaken on significant test outcomes.ResultsA total of 108 participants were recruited with 54 participants in each of the Novice and Experienced groups. Five of the eight tests were able to discriminate dexterous ability of participants in the Novice and Experienced groups. These included the Grip-lift task, GPT, P-MVC, G-MVC and the AsTex® sensory discrimination test. These tests comprised a total of 11 significant dependent variables (p < 0.05). From the test battery, outcomes were able to predict 79% of the group membership. Age and experience did not explain within-group variability for the Experienced group.ConclusionWhilst the Experienced group displayed superior performance in strength and speed, the Novice group showed superior coordination and sensory ability. From these findings, we would recommend that outcomes from the Grooved Pegboard Test, Grip-lift task, Grip Strength test and Pinch Grip strength test be used to evaluate elements of dexterity in this population.

Effectiveness of Lavendula stoechas essential oil in treatment of mild to moderate carpal tunnel syndrome: A randomized controlled clinical trial

In this study, we investigated the effectiveness of topical Lavender (Lavendula stoechas) essential oil on pain intensity, isometric pinch strength, specific parameters of electro-diagnosis study (EDS), symptom severity and functional status of patients with mild to moderate carpal tunnel syndrome (CTS). Forty-eight patients with mild to moderate CTS were enrolled in this randomized placebo-controlled trial. Group A was treated with night wrist splint and topical Lavender oil ointment. Group B was treated with night wrist splint and a placebo ointment. Patients were evaluated at baseline and after 40 days of intervention with Boston CTS questionnaire (BCTQ), Visual Analog Scale (VAS) for pain, pinch grip strength (PGS), power grip (PG), median compound motor action potential latency (MCMAPL) and median sensory nerve action potential latency (MSNAPL). At the end of the study period, both groups improved significantly in terms of BCTQ, VAS, isometric pinch powers, and EDS parameters. However, group A showed significantly greater improvements in BCTQ (mean difference: 0.39 ± 0.31 VS. 0.6 ± 0.35; P = 0.03), VAS (3.37 ± 1.86 VS. 1.33 ± 2.07; P = 0.001), and PGS (0.73 ± 0.63 VS. 0.27 ± 0.54; P = 0.01) than group B. No significant differences in PG, MCMAPL and MSNAPL were seen between the two groups. This study was the first trial of topical Lavender oil used in patients with CTS. The results of this study suggested that splinting therapy combined with topical Lavender oil is more effective than splinting and placebo in treatment of mild to moderate CTS.

Two stage reconstruction of flexor tendon injuries in zone II after missed injury or failed repair

Background: Reconstruction of flexor tendon injury of the hand after failed tendon repair or missed injury is a technically challenging problem. Repair of the tendon within the thin tight pulley system usually invites the formation of adhesion and failure of repair. A combination of a technique described by Paneva-Holevich and Hunter has been used for this problem with variable results. Methods: Twenty-five flexor tendons in 20 patients were reconstructed using a two-stage reconstruction of the flexor tendon injury. The preoperative condition of the finger was evaluated using Boyes and Stark grading modified by Wehbe et al. and all had a poor prognosis. The primary tendon injury was missed in nine patients. Primary tendon repair failed in seven patients and free tendon graft failed in three. One patient had two operative interventions: one failed primary tendon repair and one failed free tendon graft. The dominant hand was affected in (70%) of patients. Results: The average time between the original injury and the first stage operation was 10.6 mo. The mean follow-up after the second stage was 72 mo. The mean strength of pinch grip and power grip were 92.4% and 94.8%, respectively. The mean pulp to distal flexion crease distance was 12.32 mm. According to Buck-Gramcko scoring, excellent results were achieved in 18 fingers (72%), good in five fingers (20%), fair in one (4%), and poor in one (4%). No additional surgery was required after the second stage. Conclusions: The two-stage pedicled flexor digitorum superficialis technique provided a reliable and effective method for reconstruction of failed repair or missed injury of the flexor tendon in the hand in zone II. The modification of the technique presented in this study achieved a high rate of excellent and good results without increasing the rate of complications. Patient compliance is critical for the success of this procedure.

Trapeziectomy with Interpositional Arthroplasty using Acellular Dermal Matrix: Description of Technique and Early Outcomes.

Background:Trapeziectomy with interpositional arthroplasty using Repriza acellular dermal matrix is a novel technique to treat primary and secondary carpometacarpal joint arthritis. Early studies with nonautograft interposition indicate promising post-trapeziectomy space maintenance with results similar to ligament reconstruction with tendon interposition, without the potential risks and increased operating time of harvesting a tendon autograft.Methods:Eleven patients in a retrospective cohort were followed for a minimum of 6 weeks (mean, 12). Subjective and objective data were collected to assess pain, subjective improvement of symptoms, radiographic measurements of first metacarpal subsidence, key pinch strength, grip strength, and range of motion.Results:Early outcomes in our cohort compare favorably to other treatment series. On average, patients received a significant pain reduction of 63%, with 36% of patients admitting to complete pain resolution. One hundred percentage of patients admitted to overall subjective improvement in symptoms. Ninety-one percentage of patients achieved postoperative opposition of the thumb and fifth digit. Comparison with preoperative x-rays showed mean thumb metacarpal subsidence of 27%. Zigzag deformity and extra-articular acellular dermal matrix migration, due to lack of patient compliance with splint, were observed complications. Only 8.3% subsidence was observed with an impressive 45% pain reduction, in a salvage patient after revision surgery for a NuGrip implant.Conclusions:In conclusion, this is a safe and effective primary or salvage technique for Eaton grades III and IV thumb carpometacarpal arthritis with a mean subsidence within the range observed with ligament reconstruction with or without tendon interposition. Long-term study with a larger sample size is needed to investigate this technique further.

RELATIONSHIP BETWEEN POSTURAL CONTROL AND HAND FUNCTION IN THE SUBJECTS AGED 65 YEARS AND OVER

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 26.0px 'Helvetica Neue'} Purpose: This study was aimed to investigate the relationship between postural control and hand function in the elderly. Methods: One hundred-five elderly individuals that are 65 years old or over and living in a nursing home were included in the study. Postural control status (Berg Balance Scale) and hand function (manual dexterity: Nine Hole Peg Test, hand grip strength: handheld dynamometer, pinch grip strength: pinchmeter) of elderly individuals were evaluated. Results: The mean age of the subjects was 76.59±6.92 years, and there were 25 females (23.8%) and 80 males (76.2%). There was a statistically significant correlation between postural control and manual dexterity (dominant hand: r=0.857, p=0.001 and non-dominant hand: r=0.794, p=0.001). A statistically significant correlation between postural control and hand grip strength (dominant hand: r=0.430, p=0.001 and non-dominant hand: r=0.423, p=0.001), and a statistically significant relationship was found between postural control and pinch grip strength (dominant hand: r=0.390, p=0.001 and non-dominant hand: r=0.305, p=0.002). Conclusion: Our study showed that there was a significant relationship between postural control and hand function. This suggests that postural control-enhancing exercise programs might be useful. Therefore, we thought that further study is needed to investigate the effects of postural control to protect and improve the hand function for the elderly enhancing exercise programs for the elderly on the hand function to clarify the issue.

Long-term functional, subjective and psychological results after single digit replantation

ObjectiveThe aim of this study was to analyse the long-term functional, subjective, and psychological results after single-digit replantation. MethodsThirty cases of digital replantation (14 thumbs, 12 index fingers, 2 middle fingers, 1 ring finger, and 1 little finger) in 30 patients (7 females and 23 males) with a mean age of 44.2 years (20–65 years) were evaluated at the end of a mean follow-up time of 36 months (19–50 months). The active range of motion of joints, grip and pinch strength, cutaneous sensibility, upper-extremity functioning, and subjective satisfaction were determined using the Disability of Arm, Shoulder, and Hand (DASH) questionnaire and the Michigan Hand Outcomes questionnaire (MHQ). Psychological sequelae, including depression, anxiety, and posttraumatic stress disorder (PTSD), were assessed. A correlation analysis among variables was also performed. ResultsThe mean score for the DASH questionnaire was 6.6 (range: 0–39.2). The symptom of cold intolerance occurred in 53% of the patients. Two patients were diagnosed with depression, and only one patient exhibited PTSD. The DASH score had a good statistical correlation with total grip strength, pinch grip strength, and static two-point discrimination (S-2PD) (P < 0.05). Several aspects of the MHQ were also statistically relevant to some or all of the three objective results. Furthermore, the grip strength showed significant correlation with DASH and most aspects of the MHQ in multivariate logistic regression analysis (P < 0.05). ConclusionTotal grip strength is the most important factor positively related to subjective outcomes. The incidence rates of psychological symptoms after digit replantation are very low at long-term follow-up. Level of evidenceLevel IV, therapeutic study.
