“…Augurelle et al (2003) reported that 7/10 participants dropped an object during anaesthesia of the fingerpads, while none would normally drop it. Power grip of larger objects is less affected (but see Enders and Seo 2017). Based on such work (see also Shibata and Santello 2017), one might expect that the range and variation of multi-digit hand postures would be altered after the loss of haptic feedback.…”

Loss of haptic feedback impairs control of hand posture: a study in chronically deafferented individuals when grasping and lifting objects

Previous work has highlighted the role of haptic feedback for manual dexterity, in particular for the control of precision grip forces between the index finger and thumb. It is unclear how fine motor skills involving more than just two digits might be affected, especially given that loss of sensation from the hand affects many neurological patients, and impacts on everyday actions. To assess the functional consequences of haptic deficits on multi-digit grasp of objects, we studied the ability of three rare individuals with permanent large-fibre sensory loss involving the entire upper limb. All three reported difficulties in everyday manual actions (ABILHAND questionnaire). Their performance in a reach–grasp–lift task was compared to that of healthy controls. Twenty objects of varying shape, mass, opacity and compliance were used. In the reach-to-grasp phase, we found slower movement, larger grip aperture and less dynamic modulation of grip aperture in deafferented participants compared to controls. Hand posture during the lift phase also differed; deafferented participants often adopted hand postures that may have facilitated visual guidance, and/or reduced control complexity. For example, they would extend fingers that were not in contact with the object, or fold these fingers into the palm of the hand. Variability in hand postures was increased in deafferented participants, particularly for smaller objects. Our findings provide new insights into how the complex control required for whole hand actions is compromised by loss of haptic feedback, whose contribution is, thus, highlighted.

“…As a feasible and optimum choice for clinical use, the SWME is a well-established test for improved sensitivity of quantitative sensory testing, and widely applied in the assessment of neuropathy in the hospitals [45,46]. The SWME has been used in previous studies to determine sensory dysfunction at least 6 months post stroke [47].The SWME is composed of a hierarchical set of twenty monofilaments (Touch Test Sensory Evaluators, Stoetling Co., Wood Dale, IL, USA) [48].The range of monofilaments can distinguish significant sensory thresholds, including normal sensation, diminished tactile sensation, decreased protective sensation, and loss of protective sensation [49]. The assessors will start each test with a stiffness of filament with the participants' eyes closed.…”

Background An important reason for the difficulty in recovering sensorimotor dysfunction of the upper extremity in chronic stroke survivors, is the lack of sensory function, such as tactile and proprioception feedback. In clinical practice, single sensory training is only for the restoration of sensory function. Increasing evidence suggests that use of task-oriented training (TOT) is a useful approach to hand motor rehabilitation. However, neither approach is optimal since both methods are trained only for specific functional recovery. Our hypothesis is that multi-sensory feedback therapy (MSFT) combined with TOT has the potential to provide stimulating tasks to restore both sensory and motor functions. The objective of the trial is to investigate whether novel MSFT is more effective in improving arm sensorimotor function in chronic stroke phase than single TOT.Methods/Design: The study will be conducted as a multicenter, randomized, double blind controlled trial. Participants (n = 90) will be randomised into three groups to compare the effect of the multi-sensory feedback therapy group against task-oriented training group and conventional group. Participants will receive treatment at the same intensity (60 min, 5 days a week, 4 weeks, 20 hours total). Primary outcome measures for assessment of sensory function are the Semmes Weinstein monofilaments examination (SWME),two-point discrimination test (2PD) test. Secondary measures are the Action Research Arm Test (ARAT)༌Nine-Hole Peg Test (NHPT), Wolf Motor Function Test (WMFT), Box and Blocks Test (BBT), Modified Barthel Index (MBI), Instrumental activities of daily living (IADL) and Generalized Anxiety Disorder 7-Item Scale (GAD-7). Outcome mearsures will be evaluated at baseline, post treatment, and two months follow-up. All assessments will be conducted by trained assessors blinded to treatment allocation.Discussion This study will determine the acceptability and efficacy of the intervention on the hemiparetic upper limb, it may be promising tools for sensorimotor functional recovery after stroke.

“…Current measurement points for sensory assessment are mainly selected in the areas of the hand and upper limb where the function is achieved, such as the thumb and the index finger. Patients with stroke have been shown to have different sensory thresholds among the five fingers on the affected side ( Enders and Seo, 2016 ). Suda et al (2021) suggested that the light touch sensations of the thumb and the index finger were similar.…”

BackgroundAssessing hand sensation in stroke patients is necessary; however, current clinical assessments are time-consuming and inaccurate.ObjectiveThis study aimed to explore the nature of light touch sensation and two-point discrimination (2-PD) of different hand sites in convalescent stroke patients based on somatosensory evoked potentials (SEP).MethodsLight touch sensation and 2-PD of the thumb, the index finger, the little finger, thenar, and hypothenar were measured (n = 112) using sensory measurement tools. Sensory differences among the hand sites were then compared. The correlation analysis between SEP and the hemiplegic hand function was made. Sensory functions were divided into three levels: sensory intactness, sensory impairment, and sensory loss.ResultsLight touch sensations were mainly associated with sensory impairment in the finger and palm region. The 2-PD of the finger region was mainly sensory loss and that of the palm region was mainly sensory impairment. There was no statistical difference in the light touch sensation among the sites of the hand. The correlation coefficients between the 2-PD and SEP N20 amplitudes differed. The correlation coefficients of the thenar and hypothenar were the smallest, and that of the finger was the largest. Light touch sensation and 2-PD in patients with stroke were related to the hemiplegic hand function.ConclusionAny site on the hand could be selected as the measurement site for light touch sensation. The little finger and hypothenar may be appropriate sites when screening for 2-PD. To improve the patient’s recovery they could receive more sensory stimulation of the hand.
