    This pilot study measured the effectiveness of using origami to improve the overall hand function of outpatients attending an NHS hand injury unit. The initiative came from one of the authors who had used origami informally in the clinical setting and observed beneficial effects. These observed effects were tested experimentally. The design was a pilot non-randomised controlled trial with 13 participants. Allocation of the seven control group members was based on patient preference. The experimental group members attended a weekly hour of origami for six weeks, in addition to their conventional rehabilitation. Hand function of all participants was measured using the Jebsen-Taylor Hand Function Test before and after the six-week period, and additional qualitative data were gathered in the form of written evaluations from patients. The quantitative data were analysed using the Mann Whitney U test or Fisher’s exact test. Themes were highlighted from the qualitative data. The results show that there was a greater difference in the total score of the experimental group using the impaired hand between pre- and post-intervention of 11.8 seconds, compared with 4.3 seconds in the control group, but this was not statistically significant at the 5% level (p=0.06). Additionally, differences in the sub-test scores show a markedly larger improvement in the experimental group. Qualitative data indicate that the experimental group experienced the origami sessions as being enjoyable and beneficial. Further research with a larger sample and randomised group allocation is recommended to verify and expand these preliminary findings

    Objective: To investigate the impact of upper extremity deficit in subjects with tetraplegia.\ud \ud Setting: The United Kingdom and The Netherlands.\ud \ud Study design: Survey among the members of the Dutch and UK Spinal Cord Injury (SCI) Associations.\ud \ud Main outcome parameter: Indication of expected improvement in quality of life (QOL) on a 5-point scale in relation to improvement in hand function and seven other SCI-related impairments.\ud \ud Results: In all, 565 subjects with tetraplegia returned the questionnaire (overall response of 42%). Results in the Dutch and the UK group were comparable. A total of 77% of the tetraplegics expected an important or very important improvement in QOL if their hand function improved. This is comparable to their expectations with regard to improvement in bladder and bowel function. All other items were scored lower.\ud \ud Conclusion: This is the first study in which the impact of upper extremity impairment has been assessed in a large sample of tetraplegic subjects and compared to other SCI-related impairments that have a major impact on the life of subjects with SCI. The present study indicates a high impact as well as a high priority for improvement in hand function in tetraplegics.\ud \u

    Two-photon calcium imaging is already well-established in flies, fish and rodents, and is providing truly revolutionary insight into the neural basis of animal behaviour. Our critical foundational milestone is applying two-photon microscopy to NHP subjects while performing hand function tasks, given their higher brain complexity and translation potential to the human brain.https://ir.lib.uwo.ca/brainscanprojectsummaries/1038/thumbnail.jp

    Hand Function Evaluation for Dental Hygiene Students

    Dental hygiene students may struggle in dental hygiene curriculum in regards to hand function. Currently, this is not an aspect dental hygiene programs screen for or have protocol in place to help students. The research in the study examined if hand function could improve with hand function exercises and if exercises improved instrumentation scores. During a 6-week pilot study, an occupational therapist tested the hand function of a cohort of dental hygiene students. The results were recorded and the students began a 6-week hand function exercise regimen. After 6 weeks the same evaluations were preformed and the pre- and posttest data were compared. Statistical tests showed a significant improvement in hand function. After the hand function testing was complete, the scores of the cohort on the periodontal probe and 11/12 explorer were compared to students in the previous 5 cohorts. No significant improvement was made on the instrumentation scores

    Hand function improving in patients with cerebral palsy

    Get PDF
    The hand is an organ of our body that fulfills a lot of different functions. Through efficiently functioning upper limbs, we experience and learn, communicate with the world, and gain independence. In the cerebral palsy, the role of the therapist is to properly plan the hand therapy process, it requires him to have a good knowledge of what MPD is, which is associated with movement symptoms and coexisting disorders that affect the child's abnormal development. The physiotherapist must properly assess the child's functional level, anticipate and plan therapy so that the child reaches its maximum development potential. This is not an easy task because virtually every child with cerebral palsy is different, other are its movement limitations, accompanying symptoms and the environment in which he is brought up

    Predicting hand function in older adults: evaluations of grip strength, arm curl strength, and manual dexterity

    Get PDF
    Background Hand function is critical for independence in activities of daily living for older adults. Aims The purpose of this study was to examine how grip strength, arm curl strength, and manual dexterous coordination contributed to time-based versus self-report assessment of hand function in community-dwelling older adults. Methods Adults aged ≥60 years without low vision or neurological disorders were recruited. Purdue Pegboard Test, Jamar hand dynamometer, 30-second arm curl test, Jebsen-Taylor Hand Function Test, and the Late-Life Function and Disability Instrument were administered to assess manual dexterous coordination, grip strength, arm curl strength, time-based hand function, and self-report of hand function, respectively. Results Eighty-four adults (mean age = 72 years) completed the study. Hierarchical multiple regressions show that older adults with better arm curl strength (β = −.25, p < .01) and manual dexterous coordination (β = −.52, p < .01) performed better on the time-based hand function test. In comparison, older adults with better grip strength (β = .40, p < .01), arm curl strength (β = .23, p < .05), and manual dexterous coordination (β = .23, p < .05) were associated with better self-report of upper extremity function. Conclusions The relationship between grip strength and hand function may be test-specific. Grip strength becomes a significant factor when the test requires grip strength to successfully complete the test tasks. Arm curl strength independently contributed to hand function in both time-based and self-report assessments, indicating that strength of extrinsic muscles of the hand are essential for hand function

    Feasibility of a second iteration wrist and hand supported training system for self-administered training at home in chronic stroke

    Telerehabilitation allows continued rehabilitation at home after discharge. The use of rehabilitation technology supporting wrist and hand movements within a motivational gaming environment could enable patients to train independently and ultimately serve as a way to increase the dosage of practice. This has been previously examined in the European SCRIPT project using a first prototype, showing potential feasibility, although several usability issues needed further attention. The current study examined feasibility and clinical changes of a second iteration training system, involving an updated wrist and hand supporting orthosis and larger variety of games with respect to the first iteration. Nine chronic stroke patients with impaired arm and hand function were recruited to use the training system at home for six weeks. Evaluation of feasibility and arm and hand function were assessed before and after training. Median weekly training duration was 113 minutes. Participants accepted the six weeks of training (median Intrinsic Motivation Inventory = 4.4 points and median System Usability Scale = 73%). After training, significant improvements were found for the Fugl Meyer assessment, Action Research Arm Test and self-perceived amount of arm and hand use in daily life. These findings indicate that technology-supported arm and hand training can be a promising tool for self-administered practice at home after stroke.Final Accepted Versio
