    The purpose of this study was to establish norms for fine motor dexterity skills on elementary school children five to ten years old and conduct reliability and validity studies utilizing the Nine-Hole Peg Test. Sample included 1,020 students in ten elementary schools in the Las Vegas area. As children got older, their fine motor speed increased. Significant gender differences were indicated in dexterity in all ages, but only in the dominant hand. Moderately high test-retest reliability and high interrater reliability were obtained. Strong correlation between the NHPT and Purdue Pegboard Test scores provided concurrent validity of the NHPT. Significant difference in dexterity scores between regular and special education groups provided construct validity evidence. Students provided with demonstration and verbal directions showed faster dexterity speed than those with only verbal directions. This study has supported the Nine-Hole Peg Test as an effective screening tool for fine motor dexterity in school-age children

    ¬© 2023, IARIA.Abstract‚ÄĒEEG microstates are brief periods of time during which the brain‚Äôs electrical activity remains stable. The analysis of EEG microstates can help to identify the background neuronal activity at the millisecond level. The main objective of this study is to observe changes in brain microstates by varying demand during different experiment phases, involving a fatiguing exercise. The hypothesis explored in this paper is that resting state and fine motor states involve different neural assemblies and that physical fatigue induced using a wrist dumbbell flexion/extension exercise impacts these microstates. An experiment is conducted with 5 healthy participants, exploring this. Three distinct microstates are observed during the resting state and a separate set of 3 states are observed during the Nine Hole Peg Test. Changes are assessed by utilising microstate parameters such as occurrence, coverage, duration, and global explained variance. It is found that the coverage of microstate C for resting states decreases for all the participants after the dumbbell exercise. During the fine-motor task, the coverage of microstate MS3 decreases for all participants except one. These results support the involvement of different neural assemblies, but also highlight the potential that physical fatigue can be observed and identified by assessing changes in microstate features, in this case, a parameter such as coverage.Peer reviewe

    Title: Videomanual for the Administration of the Nine-Hole Peg Test according to the Czech Extended Version of the Manual for the Nine Hole Peg Test (NHPT) Abstract: Fine motor skills are a complex motor function for humans, thanks to which a person can participate in social and working life. This important function can be impaired by various diseases, traumatic injuries or degeneration. As part of comprehensive rehabilitation, an occupational therapist is a specialist who provides effective treatment. Occupational therapist uses standardized tests to evaluate the development of fine motor skills during treatment. These tests focus on various aspects of fine motor skills such as: muscle strength, range of motion, dexterity, manipulation and grip strength. The Nine Hole Peg Test assesses all of these aspects and is a very sensitive tool for evaluating treatment. Proper administration is essential for standardized tests, which should be performed exactly as instructed. For the Nine Hole Peg Test, an expanded Czech version of the NHPT manual was published in 2021, which contains new rules on how to proceed and evaluate situations arising during testing that did not have a uniform published solution in previous publications. The aim of this bachelor thesis was to create a videomanual for the administration of...BAKAL√ĀŇėSK√Č PR√ĀCE Jm√©no, pŇô√≠jmen√≠: Johana Hradilov√° Vedouc√≠ pr√°ce: Mgr.

    Question: In people who have undergone surgical carpal tunnel release, do sensorimotor-based exercises performed on the touchscreen of a tablet device improve outcomes more than a conventional home exercise program prescribed on paper? Design: Randomised, parallel-group trial with concealed allocation, assessor blinding, and intention-to-treat analysis. Participants: Fifty participants within 10 days of surgical carpal tunnel release. Intervention: Each participant was prescribed a 4-week home exercise program. Participants in the experimental group received the ReHand tablet application, which administered and monitored exercises via the touchscreen. The control group was prescribed a home exercise program on paper, as is usual practice in the public hospital system. Outcome measures: The primary outcome was functional ability of the hand, reported using the shortened form of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire. Secondary outcomes were grip strength, pain intensity measured on a 10-cm visual analogue scale, and dexterity measured with the Nine-Hole Peg Test. Outcomes were measured by a blinded assessor at baseline and at the end of the 4-week intervention period. Results: At Week 4, functional ability improved significantly more in the experimental group than the control group (MD ‚Äď21, 95% CI ‚Äď33 to ‚Äď9) on the QuickDASH score (0 to 100). Although the mean estimates of effect on the secondary outcome also all favoured the experimental group, none reached statistical significance: grip strength (MD 5.6 kg, 95% CI ‚Äď0.5 to 11.7), pain (MD ‚Äď1.4 cm, 95% CI ‚Äď2.9 to 0.1), and dexterity (MD ‚Äď1.3 seconds, 95% CI ‚Äď3.7 to 1.1). Conclusion: Use of the ReHand tablet application for early rehabilitation after carpal tunnel release is more effective in the recovery of functional ability than a conventional home exercise program. It remains unclear whether there are any benefits in grip strength, pain or dexterity. Trial registration: ACTRN12618001887268

    Preliminary validity of the Draw a Shape Test for upper extremity assessment in multiple sclerosis

    Objective To validate the smartphone sensor-based Draw a Shape Test - a part of the Floodlight Proof-of-Concept app for remotely assessing multiple sclerosis-related upper extremity impairment by tracing six different shapes. Methods People with multiple sclerosis, classified functionally normal/abnormal via their Nine-Hole Peg Test time, and healthy controls participated in a 24-week, nonrandomized study. Spatial (trace accuracy), temporal (mean and variability in linear, angular, and radial drawing velocities, and dwell time ratio), and spatiotemporal features (trace celerity) were cross-sectionally analyzed for correlation with standard clinical and brain magnetic resonance imaging (normalized brain volume and total lesion volume) disease burden measures, and for capacity to differentiate people with multiple sclerosis from healthy controls. Results Data from 69 people with multiple sclerosis and 18 healthy controls were analyzed. Trace accuracy (all shapes), linear velocity variability (circle, figure-of-8, spiral shapes), and radial velocity variability (spiral shape) had a mostly fair/moderate-to-good correlation (|r| = 0.14-0.66) with all disease burden measures. Trace celerity also had mostly fair/moderate-to-good correlation (|r| = 0.18-0.41) with Nine-Hole Peg Test performance, cerebellar functional system score, and brain magnetic resonance imaging. Furthermore, partial correlation analysis related these results to motor impairment. People with multiple sclerosis showed greater drawing velocity variability, though slower mean velocity, than healthy controls. Linear velocity (spiral shape) and angular velocity (circle shape) potentially differentiate functionally normal people with multiple sclerosis from healthy controls. Interpretation The Draw a Shape Test objectively assesses upper extremity impairment and correlates with all disease burden measures, thus aiding multiple sclerosis-related upper extremity impairment characterization

    OBJECTIVES: The effect of interferon-beta1a (INF-beta1a; Rebif) was studied in patients with chronic motor neuropathies not improving after conventional treatments such as immunoglobulins, steroids, cyclophosphamide or plasma exchange. METHODS: A prospective open study was performed with a duration of 6-12 months. Three patients with a multifocal motor neuropathy and one patient with a pure motor form of chronic inflammatory demyelinating polyneuropathy were enrolled. Three patients had anti-GM1 antibodies. Treatment consisted of subcutaneous injections of IBF-beta1a (6 MIU), three times a week. Primary outcome was assessed at the level of disability using the nine hole peg test, the 10 metres walking test, and the modified Rankin scale. Secondary outcome was measured at the impairment level using a slightly modified MRC sumscore. RESULTS: All patients showed a significant improvement on the modified MRC sumscore. The time required to walk 10 metres and to fulfil the nine hole peg test was also significantly reduced in the first 3 months in most patients. However, the translation of these results to functional improvement on the modified Rankin was only seen in two patients. There were no severe adverse events. Motor conduction blocks were partially restored in one patient only. Anti-GM1 antibody titres did not change. CONCLUSION: These findings indicate that severely affected patients with chronic motor neuropathies not responding to conventional therapies may improve when treated with INF-beta1a. From this study it is suggested that INF-beta1a should be administered in patients with chronic motor neuropathies for a period of up to 3 months before deciding to cease treatment. A controlled trial is necessary to confirm these findings

    Performance evaluation of a six-axis generalized force-reflecting teleoperator

    Work in real-time distributed computation and control has culminated in a prototype force-reflecting telemanipulation system having a dissimilar master (cable-driven, force-reflecting hand controller) and a slave (PUMA 560 robot with custom controller), an extremely high sampling rate (1000 Hz), and a low loop computation delay (5 msec). In a series of experiments with this system and five trained test operators covering over 100 hours of teleoperation, performance was measured in a series of generic and application-driven tasks with and without force feedback, and with control shared between teleoperation and local sensor referenced control. Measurements defining task performance included 100-Hz recording of six-axis force/torque information from the slave manipulator wrist, task completion time, and visual observation of predefined task errors. The task consisted of high precision peg-in-hole insertion, electrical connectors, velcro attach-de-attach, and a twist-lock multi-pin connector. Each task was repeated three times under several operating conditions: normal bilateral telemanipulation, forward position control without force feedback, and shared control. In shared control, orientation was locally servo controlled to comply with applied torques, while translation was under operator control. All performance measures improved as capability was added along a spectrum of capabilities ranging from pure position control through force-reflecting teleoperation and shared control. Performance was optimal for the bare-handed operator

    BACKGROUND: Despite the growing diffusion of robotic devices in neurorehabilitation, no previous study investigated the effects of robotic training on arm impairment due to Parkinson's disease. The aim of this pilot study was to evaluate whether robot-assisted arm training might improve upper limb function in patients with Parkinson's disease.FINDINGS: Ten patients with Parkinson's disease (Hoehn and Yahr stage 2.5-3) received ten, 45-minute, treatment sessions, five days a week, for two consecutive weeks. Robot-assisted arm training was performed with the Bi-Manu-Track (Reha-Stim, Berlin, Germany) that provides a computer-controlled, repetitive, bilateral, mirror-like practice of forearm pronation/supination and wrist extension/flexion. Patients were trained according to the following modalities: passive-passive (both arms moved by the machine) and active-active (both arms actively moving against resistance). The dominant upper limb was evaluated before and immediately after treatment as well as at two weeks of follow-up. Outcomes were the nine-hole peg test, the Fugl-Meyer assessment (upper limb section) and the Unified Parkinson's Disease Rating Scale. After treatment, a significant improvement was found in the nine-hole peg test (P\u2009=\u20090.007) as well as in the upper limb section of the Fugl-Meyer assessment (P\u2009=\u20090.012). Findings were confirmed at the 2-week follow-up evaluation only for the nine-hole peg test (P\u2009=\u20090.007). No significant improvement was found in the Unified Parkinson's Disease Rating Scale at both post-treatment and follow-up evaluations.CONCLUSIONS: Our findings support the hypothesis that robot-assisted arm training might be a promising tool in order to improve upper limb function in patients with Parkinson's disease
