BACKGROUND: Impaired sensory in acute stroke patients results in dynamic balance, gait and activities of daily living (ADL) impairment. OBJECTIVE: The aim of present study was to examine the correlation between somatosensory-evoked potential (SSEP) parameters and motor recovery in balance, gait and ADL performance in hemiparetic stroke survivors. METHODS: One hundred and one participants with hemiparetic stroke (43 males, 58 females; mean age, 6538 ± 1222 years; post-stroke duration, 199 ± 0.74 month) participated in this study. The Electro Synergy system (Viasys Healthcare; San Diego, CA, USA) was applied to measure SSEP measurement. The 101 stroke survivors were divided into three groups consistent with their SSEP results: sensory normal group; sensory impaired group; sensory absent group. All the subject participated the inpatient rehabilitation intervention for 4 weeks. Analyses of variance (ANOVA) were used to verify the group difference among the three groups after the treatment. RESULTS: ANOVA revealed the significant difference (p< 0.01). The Scheffe test demonstrated that the sensory normal group showed greater increasement in Modified Barthel Index (MBI), Fugl-Myer Assessment (FMA), Trunk Impairment Scale (TIS), Berg Balance Scale (BBS) and Functional Ambulation Category (FAC) scores than the sensory impaired and absent group (p< 0.05). CONCLUSIONS: Our research provides therapeutic evidence that correlation of somatosensory functions on motor recovery, balance, gait, and ADL in patients with hemiplegic stroke.
BACKGROUND: Although patients with frozen shoulders have the range of motion (ROM) of their shoulder’s abduction movements measured at hospital and the physical therapy visits, multiple visits to check for progress is often difficult. Thus, we developed an artificial intelligence-based image recognition detectable sensor (AIRDS) intended for easy use at home. OBJECTIVE: The purpose of this study was to determine the accuracy of a sensor (AIRDS) measuring shoulder abduction angle, thus offering a valid and feasible system for monitoring patients with frozen shoulder. METHODS: Ten patients with frozen shoulder (5 males, 5 females) performed shoulder joint movements while being measured with the AIRDS system and the 3-dimensional Vicon system. The measure of the outcome included the linear regression of the shoulder abduction joint kinematics. RESULTS: Linear regression analysis of the AIRDS system and the Vicon system demonstrated a significant correlation coefficient of R2= 0.9979 (P< 0.05). CONCLUSIONS: Our results provide novel, promising evidence that AIRDS can accurately measure the timing and total spatial characteristics of clinical movements. AIRDS is designed to provide real-time ROM measurements for joint mobility using artificial intelligence instead of the judgement of the physical therapist.
The importance of core stabilization exercises for extremities associated with dynamic spinal stabilization prior to movement has been demonstrated. However, no previous studies have investigated the muscle-coordinated effects on the upper trapezius (UT), anterior deltoid (AD), pectoralis major (PM), bilateral transverse abdominis (TrA), bilateral internal oblique (IO), and bilateral external oblique (EO) in healthy adults. The purpose of this study was to compare the effects of the dynamic neuromuscular stabilization (DNS) breathing technique and the abdominal bracing (AB) technique on UT, AD, PM, bilateral IO/TrA, and bilateral EO motor control in healthy participants during horizontal shoulder adduction. Thirty-six participants, eight of whom were female, were randomized into an AB and a DNS group and performed horizontal shoulder adduction with loads (8 and 17 lb). The clinical outcomes were UT, AD, and PM muscle activation and TrA/IO and EO muscle activation. Paired t-tests were used to analyze electromyography (EMG) data to determine statistically significant differences in muscle activity between the two techniques. For the EMG analysis, the maximal voluntary isometric contraction was measured for normalization and then divided by the EMG amplitude value. The results showed that UT, AD, and PM muscle amplitudes were lower and TrA/IO and EO muscle amplitudes were higher with DNS than with AB ([Formula: see text]). Our findings provide clinical evidence that core exercise with DNS is more effective in lessening UT, AD, and PM muscle activation and improving bilateral TrA/IO motor control than with AB.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
