“…Thus, different parts of the fingers have different receptors, thresholds, and types of sensations. Post-stroke sensory dysfunction is caused by a variety of factors, including damage to the focal brain areas that can affect hand function ( Tyson et al, 2008 ; Umeki et al, 2018 ).…”

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.

“…We know that patients suffering from stroke and contralesional paresis of arm and/or leg usually also experience sensory impairment at the paretic limb(s). The degree of sensory impairment is related to the severity of motor paralysis [ 14 ]. Beyond, it has been suggested that stroke patients may have an impairment in own body size perception, e.g.…”

Recent studies have suggested that people’s intent and ability to act also can influence their perception of their bodies’ peripersonal space. Vice versa one could assume that the inability to reach toward and grasp an object might have an impact on the subject’s perception of reaching distance. Here we tested this prediction by investigating body size and action capability perception of neurological patients suffering from arm paresis after stroke, comparing 32 right-brain-damaged patients (13 with left-sided arm paresis without additional spatial neglect, 10 with left-sided arm paresis and additional spatial neglect, 9 patients had neither arm paresis nor neglect) and 27 healthy controls. Nineteen of the group of right hemisphere stroke patients could be re-examined about five months after initial injury. Arm length was estimated in three different methodological approaches: explicit visual, explicit tactile/proprioceptive, and implicit reaching. Results fulfilled the working hypothesis. Patients with an arm paresis indeed perceived their bodies differently. We found a transient overestimation of the length of the contralesional, paretic arm after stroke. Body size and action capability perception for the extremities thus indeed seem to be tightly linked in humans.

Constraint-induced movement therapy (CIMT) is used for the rehabilitation of motor function after stroke. The aim of this review was to investigate its effect on persons-reported outcomes of health status (PROsHS) compared with conventional therapy. The study was a systematic review and meta-analysis registered in PROSPERO (CRD42019142279). Five databases PubMED, PEDro, OTSeeker, CENTRAL and Web of Science were searched. Randomized controlled trials were included if they assessed PROsHS. Mean scores of PROsHS, sample size and dose of CIMT and control groups interventions were extracted. The result was analyzed using qualitative and quantitative syntheses. Nine studies (n = 558) were included in the review. From the result, CIMT significantly improved PROsHS postintervention. However, postintervention, there was no statistically significant difference between groups for the upper limb [Mean difference (MD) = 6.67, 95% confidence interval (CI) = –2.09 to 15.44, P = 0.14] and the lower limb (MD = –1.86, 95% CI = –16.29 to 12.57, P = 0.80). Similarly, there was no statistically significant percentage of variation across studies, upper limb (I 2 = 0%, P = 0.92) and lower limb (I 2 = 0%, P = 0.86). For the lower limb at follow-up, there was no statistically significant difference between groups (MD = 0.97, 95% CI = –13.59 to 15.53, P = 0.90). When upper and lower limbs studies were pooled, there was no statistically significant difference between groups postintervention (MD = 0.22, 95% CI = –0.15 to 0.58, P = 0.24) and at follow-up (MD = 0.03, 95% CI = –0.43 to 0.49, P = 0.90). CIMT improves PROsHS after stroke. However, it is not superior to conventional therapy based on the current literature.
