“…Pinch strength was measured with a reliable and accurate hand-held pinch metre, where participants were instructed to exert maximum force to perform three types of pinches: tip pinch, Palmar pinch and lateral pinch strength. The hand-held dynamometer and pinch metre are sensitive and repeatable testing instruments 26…”

ObjectivesTo compare the efficacy of a traditional cock-up splint, which supports the wrist only, with a modified splint that supports the wrist and the metacarpophalangeal (MCP) joints of the medial four digits in the treatment of carpal tunnel syndrome (CTS).DesignAn assessor-blind randomised controlled trial.SettingHospital-based hand therapy clinics.ParticipantsFifty-nine adults with mild-to-moderate CTS were randomly assigned to wear a wrist splint (control group) or an MCP splint (intervention group) for 6 weeks.Outcome measuresThe standardised outcome measures used included grip and pinch strength, the static two-point discrimination test, Phalen’s manoeuvre test, Tinel’s sign and the Boston CTS Questionnaire.ResultsBoth groups improved significantly from splint use in some clinical features. The wrist splint and the MCP splint groups had significant improvements in lateral pinch strength (p=0.032 and p=0.002, respectively), two-point discrimination of the thumb (p=0.003 and p=0.041, respectively), two-point discrimination of the index (p=0.035 and p=0.023, respectively) and the Phalen’s manoeuvre symptoms (p=0.025 and p=0.002, respectively). The MCP splint group had additional improvements over the wrist splint group in tip pinch (p=0.012) and Palmar pinch (p=0.011) strength.ConclusionSplinting is a practical and effective intervention option for improving the symptoms of CTS. A wrist splint that incorporates the MCP joints is more effective than the traditional wrist-only splint, with long-lasting improvements that remained consistent after 6 months of the splint intervention. Using the more effective MCP splint may consequently reduce disability, facilitate return to work and lower the associated costs.Trial registration numberISRCTN13189602.

“…The Biometric E-Link Evaluation System (Biometrics Ltd, Newport, UK) was used to determine the grip and pinch strengths. Grip and pinch measurements were taken in the standardized sitting position with the shoulder of the patient kept in the neutral position and the elbow flexed to 90° [ 22 ]. The grip strengths of patients with single digit replantation ( n = 14) or amputation ( n = 20) were recorded in the standardized level II position.…”

Background The success of digit replantation is mainly based on survival rates. The functional outcome as well as the recovery of sensibility are essential parameters for judging the outcome after digit replantation but have been poorly assessed in previous studies. Patients and methods Forty-eight patients with 56 complete traumatic digit amputations occurring between 2008 and 2013 returned for a follow-up examination, the earliest being 6 months postoperatively. Each patient’s range of motion, fingertip-to-table distance, fingertip-to-palm distance, grip and pinch strengths, static two-point discrimination (2-PD), and Semmes–Weinstein monofilament (SWM) test level were assessed in order to compare functional outcome and recovery of sensibility between successful replantation (n = 19) and primary or secondary amputation (n = 37). Subjective assessments of the pain level and function of the upper extremity were performed using the numerical rating scale and the DASH score, respectively. Results Replanted digits achieved 58% of the median total range of motion of the corresponding uninjured digits. Grip and pinch strength were not significantly different after thumb or finger replantation or amputation. Recovery of sensibility was excellent after replantation, with a median static 2-PD of 5 mm and a reduction of pressure sensibility of two levels of the SWM test compared to the contralateral side. After amputation, the median static 2-PD was also very good, with a median value of 6 mm and a reduction of pressure sensibility of only one level according to the SWM test. There was significantly less pain after replantation at rest (p = 0.012) and under strain (p = 0.012) compared to patients after amputation. No significant differences were observed in the DASH score between the two groups. Conclusion Comparable functional results and sensory recovery but significantly less pain at rest and under strain can be expected after digit replantation when compared to digit amputation. Level of evidence IV.

“…Based on the high values of the intraclass correlation coefficient (ICC), the tip pinch (0.783–0.895) and palmar pinch (0.752–0.903) force sense tests demonstrated good reliability for all the variables. The ICCs for the key pinch (0.712–0.881) indicated fair to good relative test-retest reliability ( Li et al, 2020 ).…”

Pinch force sense plays an important role in the performance of daily finger movements, including tip, key, palmar pinch. The present study investigated the roles of pinch type in the sensation of pinch force among healthy participants in the ipsilateral force reproduction trial. This study instructed forty healthy adult subjects (20 women and 20 men) in producing reference forces at different levels [10, 30, 50% maximal voluntary isometric contraction (MVIC)] by adopting 3 pinch types (tip, key, and palmar pinches) and in reproducing the above force levels with the identical hand. Our study revealed that subjects are significantly more sensitive detecting alterations of pinching forces with tip pinch but not key or palmar pinch under high forces (30 and 50% MVIC) but not at lower force levels (10% MVIC).
