“…When participants did consult primary literature, this included familiar sources such as the guideline for Screening Hand Skills described in the Occupational Therapy for Children textbook. Furthermore, their familiarity with the UFS IHM-C, which was published in the South African Journal of Occupational Therapy (SAJOT) 13,25 attested to participants accessing research published locally.…”

“…Most of the participants (n=242; 82.9%) indicated that they were not familiar with any of the listed formal assessment methods. Of the remaining 50 (17.1%) that indicated their familiarity 28 , (9.6%), indicated that the Screening Activities of Hand Skills guideline described by Exner in the Occupational Therapy for Children 6th Edition textbook was the most familiar to participants, followed by an additional fine motor assessment, the FDT for children (n=17; 5.8%), and the in-hand manipulation assessment, UFS IHM-C, developed in South Africa by Visser et al 13,25 (n=15, 5.1%). However, for all the instruments, there were fewer responses of their reported use in comparison to the familiarity indicated.…”

“…Ideally, a formal method should include a norm-or criterion-referenced evaluation with established standardised procedures for administration and scoring determined according to a formal instrument development process, which includes evaluated psychometric properties 16,23,24 . The instruments described in the literature that have evidence of formal instrument development, include the UFS In-Hand Manipulation Checklist (UFS IHM-C) 13,25 , the In-hand Manipulation Test -Quality section (IMT-Q) 6,26 , Test of In-hand Manipulation (TIHM) 4,27 that was refined into the TIHM-Revised (TIHM-R) 12 , the Observational Protocol of In-Hand Manipulation 5,28 , the unnamed test of Pehoski 15,22 , the Test of In-hand Manipulation Skills (TIMS) 14 , the unnamed test of Bonnier 29 , and the Timed-Test of In-Hand Manipulation (TIHM-T) 30 . An occupational therapist can also use formal hand function assessments that include features of in-hand manipulation to guide their clinical observations.…”

“…During the assessment of the child's functional limitations, obtaining adequate and accurate information on in-hand manipulation by means of a suitable assessment instrument is vital, as this guides the intervention plan and ensures quality service delivery 10 . Instruments used for assessing in-hand manipulation in clinical practice have been described in the literature 5,[11][12][13][14][15] . A review of these instruments, based on the Instrument Evaluation Framework of Rudman and Hannah 16 , was performed by the principal investigator.…”

“…None of these instruments met all the criteria related to clinical utility, standardisation, purpose, psychometric properties, and the client's perspective required for hand function assessments 17 . Arguably, this could be the reason why therapists appear to assess in-hand manipulation informally by using checklists or clinical observations 13 . However, no research was found to substantiate these assumptions.…”

INTRODUCTION: Assessment of in-hand manipulation is fundamental to guide treatment for children with fine motor delays. Limited literature is available on how South African occupational therapists assess in-hand manipulation. This study aimed to describe which current in-hand manipulation assessment methods are used and what the preferences of occupational therapists in all areas of paediatric practices are regarding a suitable instrument METHODS: Quantitative cross-sectional study design with a non-probability purposive sampling method was used. Participants completed an EvaSys survey system online questionnaire RESULTS: Two-hundred-and-ninety-two (n=292) occupational therapists registered with the HPCSA participated. Limited familiarity (n=50; 17.1 %) with the formal assessment instruments described in literature was reported. The informal assessment methods most commonly used were subjective observation of tasks (n=287; 98.3%) of scholastic tasks (n=261; 89.4%) and play tasks (n=255; 87.3%) for children between the ages of five to six years (n=273; 93.5%). Preferences supported a descriptive instrument accompanied by a user manual that is administered under 15 minutes, in multiple languages, and with attention to the quality of movements and compensatory techniques used by the child CONCLUSION: Results showed that the current and preferred assessment methods used by occupational therapists might provide guidance for the future development of a contextual, relevant in-hand manipulation instrument for paediatric practices in South Africa Keywords: in-hand manipulation; assessment methods; paediatric practice

MOGrip: Gripper for multiobject grasping in pick-and-place tasks using translational movements of fingers

Humans use their dexterous fingers and adaptable palm in various multiobject grasping strategies to efficiently move multiple objects together in various situations. Advanced manipulation skills, such as finger-to-palm translation and palm-to-finger translation, enhance the dexterity in multiobject grasping. These translational movements allow the fingers to transfer the grasped objects to the palm for storage, enabling the fingers to freely perform various pick-and-place tasks while the palm stores multiple objects. However, conventional grippers, although able to handle multiple objects simultaneously, lack this integrated functionality, which combines the palm’s storage with the fingers’ precise placement. Here, we introduce a gripper for multiobject grasping that applies translational movements of fingertips to leverage the synergistic use of fingers and the palm for enhanced pick-and-place functionality. The proposed gripper consists of four fingers and an adaptive conveyor palm. The fingers sequentially grasp and transfer objects to the palm, where the objects are stored simultaneously, allowing the gripper to move multiple objects at once. Furthermore, by reversing this process, the fingers retrieve the stored objects and place them one by one in the desired position and orientation. A finger design for simple object translating and a palm design for simultaneous object storing were proposed and validated. In addition, the time efficiency and pick-and-place capabilities of the developed gripper were demonstrated. Our work shows the potential of finger translation to enhance functionality and broaden the applicability of multiobject grasping.

Aim Accurate assessment of in-hand manipulation is imperative when treating children with fine motor delays. A clinically suitable instrument for in-hand manipulation is required to inform the paediatric developmental and rehabilitation context. Critical evaluation of the available instrument is required to make an informed decision and direct future research. The aim of the study was to assess the available literature with a view to writing a scoping review on in-hand manipulation assessment instruments for children. Methods The Arskey and O'Malley six-stage scoping review was applied. Fifteen databases were sourced for articles published between 1 January 1990 and 31 December 2020. After identifying 33 eligible articles that met the inclusion criteria, the data obtained from the articles were charted. Results Eleven in-hand manipulation assessment instruments were identified and summarised according to (i) the constructs of in-hand manipulation included; (ii) clinical utility aspects of applicability and practicality and (iii) psychometric properties. Conclusion At the time of the review, none of the instruments had comprehensively completed the instrument development process to the point of standardisation with evaluated psychometric properties. Further research is recommended for the development of a gold standard in-hand manipulation assessment instrument.
