Objective: The purpose of this study was to investigate the effects of resistance exercise in comparison with those of common exercise on chronic neck pain (CNP) to provide useful clinical guidelines for reducing pain or increasing cervical range of motion (ROM), upper trapezius tone, disability level, and quality of life (QOL). Methods: The subjects were randomized into a cervical and scapula-focused resistance exercise group (CSREG, n = 21) or trapezius massage group (TMG, n = 20). All groups received a 4-week, five times per week CSRE or TM program for CNP. The visual analogue scale (VAS) score, cervical ROM, myotonometer measures (upper trapezius tone, stiffness, and elasticity), neck disability index (NDI), and short form-36 (SF-36) were identified as the primary outcomes. Results: Within-group changes in VAS, cervical ROM, myotonometer measures, NDI, and SF-36 were significant in the CSREG and TMG (P < .05). The between-group changes in VAS, cervical rotation, myotonometer (upper trapezius tone and stiffness), NDI, and SF-36 after intervention showed significant differences between the CSREG and TMG (P < .05). Conclusion: These results suggest that the CSRE program is effective in improving pain, cervical ROM, upper trapezius tone, disability level, and QOL in patients with CNP. More comprehensive studies with longer follow-up durations are needed to better understand the potential effects of the CSRE program in patients with CNP.

Gait characteristics are closely associated with executive functions including basic and high-level cognitive processes such as attention, working memory, decision-making, and problem-solving. Impaired cognitive function resulting from dementia is associated with loss of balance and poor activities of daily living (ADLs). If associations between gait parameters, balance, and ADLs are observed, then quantitative gait analysis may be optimal for reinforcing balance and ADL assessments in people with dementia. This study aimed to determine the association between balance, gait, and ADLs in older adults with dementia. A cross-sectional study was conducted in 46 older adults who have been diagnosed with dementia. Measurements including the Mini-Mental Statement Examination-Korean version (MMSE-K), Berg Balance Scale (BBS), 10-meter walk test (10MWT), Modified Barthel index (MBI), and GAITRite were used to assess cognitive function, balance, walking speed, ADLs, and gait parameters, respectively. The Pearson product correlation coefficient (r) was used for correlation analysis. Among the gait parameters, velocity was positively associated with the BBS, 10MWT, and MBI (r = 0.341-0.516, P > .05). Step length (r = 0.301-0.586, P > .05), stride length (r = 0.329-0.580, P > .05), and walk ratio (r = 0.324-0.556, P > .05) were positively associated with the MMSE-K, BBS, 10MWT, and MBI. A moderate positive association between single support time and MBI was observed (r = 0.308, P = .039). Additionally, a moderate negative association between double support time and the MBI was observed (r = −0.349, P = .019). This study presents the first empirical evidence on the association between balance, gait, and ADLs in older adults with dementia. This study identified important associations between balance, gait, and ADL assessments in people with dementia. Further studies involving targeted interventions addressing gait parameters and improving balance and functional performance in people with dementia are required in the future.

Background: Patients with stroke generally have diminished balance and gait. Mobilization with movement (MWM) can be used with manual force applied by a therapist to enhance talus gliding movement. Furthermore, the weight-bearing position during the lunge may enhance the stretch force. Objectives: This study aimed to compare the effects of a 4-week program of MWM training with those of static muscle stretching (SMS). Ankle dorsiflexion passive range of motion (DF-PROM), static balance ability (SBA), the Berg balance scale (BBS), and gait parameters (gait speed and cadence) were measured in patients with chronic stroke. Methods: Twenty patients with chronic stroke participated in this study. Participants were randomized to either the MWM (n = 10) or the SMS (n = 10) group. Patients in both groups underwent standard rehabilitation therapy for 30 min per session. In addition, MWM and SMS techniques were performed three times per week for 4 weeks. Ankle DF-PROM, SBA, BBS score, and gait parameters were measured after 4 weeks of training. Results: After 4 weeks of training, the MWM group showed significant improvement in all outcome measures compared with baseline (p < 0.05). Furthermore, SBA, BBS, and cadence showed greater improvement in the MWM group compared to the SMS group (p < 0.05). Conclusions: This study demonstrated that MWM training, combined with standard rehabilitation, improved ankle DF-PROM, SBA, BBS scores, and gait speed and cadence. Thus, MWM may be an effective treatment for patients with chronic stroke.

The elastic-taping method of the proprioceptive neuromuscular facilitation (PNF) concept is nonexistent. Therefore, our study aimed to investigate the effect of treadmill training (TT) using PNF lower-leg taping (PNFLT) on walking and balance ability in patients with stroke. There were a total of 27 patients: a stroke allocated control group (n=13) and an experimental group (n=14). The control group performed the TT and the experimental group performed the TT using PNF taping five times a week for 6 weeks. Walking and balance ability were measured using the 6-min walk test (6MWT), the 10-m walking test (10MWT), and the timed up and go test (TUG). Before and after the intervention, a paired t-test was performed to compare different within-group differences. Independent t-tests were performed to compare different between-group differences. All statistical significance levels were set at α of 0.05. After intervention, 6MWT, 10MWT and TUG improved significantly in PNFLT-TT and TT group (P<0.01). After intervention, the PNFLT-TT group showed more effective changes that the TT group in 6MWT, 10MWT, and TUG (P<0.05 and <0.01) between PNFLT-TT and TT group. The intervention of PNFLT-TT was effective in improving walking and balance ability in patients with stroke. Basic elastic tape for the PNF concept and TT may be useful interventions as a program to improve walking and balance ability in patients with stroke.

Vision and eye movements play a crucial role in maintaining postural stability. This study investigated the relationship between eye movements and postural control in healthy adults using mobile eye-tracking technology and posturography. Forty healthy participants underwent assessments of eye movements using a mobile eye-tracking system and postural stability using Tetrax posturography under various sensory conditions. Pearson correlation coefficients were computed to examine associations between eye movement parameters and postural control indices. Significant correlations were found between eye movement parameters and postural stability indices. Faster and more consistent horizontal eye movements were associated with better postural stability (r = −0.63, p < 0.05). Eye movement speed variability positively correlated with weight distribution indices under normal eyes open (r = 0.65, p < 0.05) and closed (r = 0.59, p < 0.05) conditions. Coordination of horizontal and vertical eye movements positively correlated with postural control (r = 0.69, p < 0.01). Negative correlations were observed between eye movement coordination and Fourier indices in various frequency bands (p < 0.05) and the stability index under different head positions (p < 0.05). The findings provide insights into sensory integration mechanisms underlying balance maintenance and highlight the importance of integrated sensory processing in postural stability. Eye movement assessments have potential applications in balance evaluation and fall risk prediction.
