Estimating muscle force by surface electromyography (sEMG) is a non-invasive and flexible way to diagnose biomechanical diseases and control assistive devices such as prosthetic hands. To estimate muscle force using sEMG, a supervised method is commonly adopted. This requires simultaneous recording of sEMG signals and muscle force measured by additional devices to tune the variables involved. However, recording the muscle force of the lost limb of an amputee is challenging, and the supervised method has limitations in this regard...

Distal radius fractures (DRF) may trigger, reveal or decompensate acute carpal tunnel syndrome (CTS) in 0.5-21% of cases. Internal fixation and median nerve release must then be carried out urgently. Less invasive approaches have been described for both the median nerve release using an endoscopic device and for the DRF fixation using a volar locking plate. We assessed the feasibility of DRF fixation and median nerve release through a single, minimally-invasive 15mm approach on a series of 10 cases. We reviewed retrospectively 10 consecutive cases of DRF associated with symptomatic CTS in 8 women and 2 men, aged 57 years on average...

PURPOSE: Progressive physical frailty in older adults is associated with increased risk of falls, disability, institutionalization, and mortality. Although associations between diabetes and frailty have been observed, the impact of diabetes on frailty in older Hispanics is largely unexplored. We examine the association of diabetes on the odds of frailty among older Mexican Americans. METHODS: Using data from the Hispanic Established Population for the Epidemiological Study of the Elderly from 1995 until 2012, frailty was assessed by slow gait, weak hand grip strength, exhaustion, and unexplained weight loss (n = 1327)...

BACKGROUND: Spinal cord injury may cause cortical reconstruction. We, therefore, explored thechanges in cortical activation before and after anterior cervical decompression and fusion surgery in patients with Hirayama disease (HD). METHODS: 17 HD cases were performed anterior cervical decompression and fusion surgery. BOLD-fMRI scan was performed preoperatively, 3 months, 6 months and 1 year after surgery. Activated voxels were compared between both hands after adjusting for head motion, slice timing, spatial normalization and image smoothing...

BACKGROUND/OBJECTIVES: Reduced appetite is a recognised physiological symptom in survivors of critical illness. While reduced appetite has been reported by patients after intensive care unit (ICU) discharge, quantification using visual analogue scales (VAS) has not been previously performed, and follow-up duration has been limited. We aimed to describe appetite scores in ICU survivors during the first 3 months after ICU discharge and explore association with systemic inflammation. SUBJECTS/METHODS: Secondary analysis of data collected in a complex rehabilitation intervention trial (RECOVER)...

INTRODUCTION: The beneficial effect of dietary omega-3 supplementation in younger adults or older people with acute or chronic disease is established. Knowledge is now needed about the effect in medically stable older people. The objective of this study is to examine and assess the evidence for a role of dietary omega-3 polyunsaturated fatty acid (PUFA) supplementation in older adults on (1) muscle mass and muscle strength, (2) inflammatory biomarkers and (3) physical activity. METHODS AND ANALYSIS: A systematic review and data synthesis will be conducted of randomised controlled trials in older people not recruited for any given disease diagnosis...

Motor coordination and physical fitness are multidimensional concepts which cannot be reduced to a single variable. This study evaluated multivariate relationships among morphology, physical fitness and motor coordination in 74 pre-pubertal girls 8.0-8.9 years of age. Data included body dimensions, eight fitness items and four motor coordination tasks (KTK battery). Maturity status was estimated as percentage of predicted mature stature attained at the time of observation. Canonical correlation analysis was used to examine the relationships between multivariate domains...

BACKGROUND: Low muscle mass and strength are highly prevalent in inpatients. It is acknowledged that low muscle mass and strength are associated with falls in community-dwelling older adults, but it is unknown if these muscle measures are also associated with falls in a population of older inpatients. This study aimed to investigate the association between muscle measures and pre- and post-hospitalization falls in older inpatients. METHODS: An inception cohort of patients aged 70 years and older, admitted to an academic teaching hospital, was included in this study...

Interaction with an object often requires the estimation of its mechanical properties. We examined whether the hand that is used to interact with the object and their handedness affected people's estimation of these properties using stiffness estimation as a test case. We recorded participants' responses on a stiffness discrimination of a virtual elastic force field and the grip force applied on the robotic device during the interaction. In half of the trials, the robotic device delayed the participants' force feedback...

Because several studies have implicated serotonin as a regulator of bone mass, we here explore its potential association on fracture risk and falls, as on bone mineral density (BMD) and muscle strength, in humans. Serum levels of serotonin were analyzed in 950 men (aged 69 to 81 years), participating in the Gothenburg part of the population-based study MrOS Sweden. Men taking selective serotonin reuptake inhibitors (SSRIs) had a mean value of 31.2 μg/L compared with 159.4 μg/L in those not taking SSRIs...

BACKGROUND: Patients with distal radius fractures (DRF) often have limited range-of-motion (ROM) in multiple planes of movement. No studies have comprehensively examined the impact of various ROM limitations on physical function. METHODS: We performed a multi-center, longitudinal study of 138 patients with conservatively managed DRF. ROM measures were taken at initial evaluation, and at 4 and 8 weeks later. Self-reported physical function was indexed by the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH)...

We report the outcomes of scapholunate intercarpal ligamentoplasty in 26 wrists. For 15 wrists with static instability and 11 with dynamic instability, we used a free palmaris longus graft to reconstruct the dorsal part of the scapholunate interosseous ligament and the dorsal intercarpal ligament. These patients were evaluated for pain and active wrist range of motion, grip strength and radiological appearance after a mean follow-up of 36 months (range 12-54) after surgery. Pain score was improved from 4.5 to 1...

Spider monkeys are interesting to study with regard to hand preferences, as they are one of the few primate species that lack a thumb and, thus, are unable to perform a precision grip. Further, being platyrrhine primates, they also largely lack independent motor control of the digits and, thus, have only limited manual dexterity. It was therefore the aim of the present study to assess hand preferences in black-handed spider monkeys ( Ateles geoffroyi ) in 4 tasks differing in task demand: simple unimanual reaching for food and 3 versions of the widely used tube task, including 2 bimanual versions that differ from each other in the degree of fine motor control needed and a unimanual version that does not require coordinated action of the hands...

The present case study details sensations elicited by electrical stimulation of peripheral nerve axons using an implanted nerve cuff electrode, in a participant with a transhumeral amputation. The participant uses an osseointegrated electromechanical interface, which enables skeletal attachment of the prosthesis and long-term, stable, bidirectional communication between the implanted electrodes and prosthetic arm. We focused on evoking somatosensory percepts, where we tracked and quantified the evolution of perceived sensations in the missing hand, which were evoked from electrical stimulation of the nerve, for over 2 years...

Background: In older persons, lower hand grip strength is associated with poorer cognition. Little is known about how the rate of muscle contraction relates to cognition and upper extremity motor function, and sex differences are understudied. Methods: Linear regression, adjusting for age, race, education, body mass index, appendicular lean mass, and knee pain assessed sex-specific cross-sectional associations of peak torque, rate of torque development (RTD) and rate of velocity development (RVD) with cognition and upper extremity motor function...

Background: the appropriateness of lowering systolic blood pressure remains controversial in the oldest-old. We tested whether systolic blood pressure is associated with all-cause mortality and change in cognitive function for patients prescribed antihypertensive treatment and those without treatment. Methods: we studied participants in the population-based Leiden 85-plus cohort study. Baseline systolic blood pressure and use of antihypertensive treatment were predictors; all-cause mortality and change in cognitive function measured using the Mini-Mental State Examination were the outcomes...

The current study examined the effects of an exercise program on health related physical fitness, self-efficacy, and physical activity levels in adults with intellectual disability. The study used pre- and posttest experimental research design with a control group. Total of 23 adults with intellectual disability were recruited with 12 assigned for the exercise group and 11 for the control group, separately. The measures of health related physical fitness included cardio pulmonary endurance (step-test), body composition (bioelectrical impedance analysis), flexibility (sit and reach), muscle endurance (sit-up), and strength (hand grip strength)...
