“…Consistent with our findings, Uğurlu et al found that among stroke patients, four (12.1%) had hemorrhagic and the others (87.9%) had ischemic stroke (10) . Similar to our results, When the stroke types were examined by İsnaç et al it was discovered that 63.7 percent (n = 19) were of the ischemic cases, and 36.7 percent (n= 11) of them were hemorrhagic (12) .…”

Background: Stroke is the primary cause of long-term disability and mortality among adults and is classified as a chronic illness. After suffering a stroke, spasticity manifests in around thirty percent of cases. Aim: To evaluate the effect of spasticity in chronic hemiplegic upper extremities on electrophysiological and morphological characteristics of the median and ulnar nerves. Subjects and methods: This was cross-sectional research that was performed on 50 patients with chronic stroke at the

In the early stage of stroke, due to the weak deltoid and supraspinatus on the HUE, combined with the effect of gravity, the humeral head could not be effectively xed into the glenoid, which may lead to the occurrence of SS [1,19] .…”

“…Then, the degree of SS and upper limb dysfunction could be further aggravated [1,3] . Electrodiagnosis and ultrasound medicine studies show that, in post-stroke patients, the peripheral nerves of the HUE could exist different degrees of impairment which seriously delays the function recovery of the HUE [6][7][8] . However, the impacts of SS on the HUE electroneurographic characteristics in post-stroke are rarely reported.…”

Background: After stroke, the peripheral nerves of the hemiplegic upper extremity (HUE) could exist impairments which seriously delay the function recovery of the HUE. However, the impacts of shoulder subluxation (SS) on the HUE electromyography characteristics in post-stroke are rarely reported. Therefore, this study was to investigate the impact of SS on peripheral nerve conduction and function of the HUE in post-stroke patients.Methods: A retrospective, matched-pair study was conducted. 30 post-stroke in-patients (15 patients for each group) were selected and their peripheral nerves of bilateral upper limbs were used to be underdone by the electroneurographic examination. The characteristics of patients, such as age and type of stroke, were recorded and paired. The electroneurographic parameters of upper limb motor/sensory nerves contained: the compound muscle action potential (CMAP) amplitude and latency of suprascapular, axillary, musculocutaneous, radial, median and ulnar nerves; the motor conduction velocity/ the sensory nerve action potential (SNAP) amplitude and latency of median, ulnar and radial nerves. The Brunnstrom stage scale was used to evaluate the motor function of the HUE.Results: The CMAP amplitude of each nerve in the HUE of both groups was lower than that in the healthy side (P < 0.05). CMAP amplitude of peripheral nerves (except ulnar) in the HUE of SS group was decreased (P < 0.05). The CMAP latency of the suprascapular, axillary and musculocutaneous nerves was longer than that of the healthy side in the SS group (P < 0.05). The axillary nerve CMAP latency in the SS group was prolonged more (P < 0.05). The motor conduction velocity of the median nerve on the HUE in the SS group was lower than that of the HUE in the N-SS group (P < 0.05). The SNAP amplitudes of the nerves in the HUE in both groups were lower than those in the healthy side (P < 0.05). The Brunnstrom stage of HUE in the SS group was lower (P < 0.05).Conclusions: Stroke may lead to extensive damage of the HUE nerves, and SS may aggravate the damage of these nerves, delaying the recovery of upper limb function.
