Abstract Background and Purpose. Visual feedback related to weight distribution and center-of-pressure positioning has been shown to be effective in increasing stance symmetry following stroke, although it is not clear whether functional balance ability also improves. This study compared the relative effectiveness of visual feedback training of center-of-gravity (CoG) positioning with conventional physical therapy following acute stroke. Subjects. Forty-six people who had strokes within 80 days before the study, resulting in unilateral hemiparesis, and who were in need of balance retraining participated. Methods and Materials. Initially, subjects were randomly assigned to visual feedback or conventional physical therapy groups for balance retraining until 16 subjects per group were recruited. The next 14 subjects were assigned to a control group. All subjects received physical therapy and occupational therapy (regular therapy) 2 hours a day, and subjects in the 2 experimental groups received additional balance training 30 minutes a day until discharge. The visual feedback group received information about their CoG position as they shifted their weight during various activities. The conventional therapy group received verbal and tactile cues to encourage symmetrical stance and weight shifting. Static (postural sway) and activity-based measures of balance (Berg Balance Scale, gait speed, and the Timed “Up & Go” Test) were contrasted across the 3 groups at baseline, at discharge, and at 1 month following discharge using an analysis of variance for repeated measures. Results. All groups demonstrated marked improvement over time for all measures of balance ability, with the greatest improvements occurring in the period from baseline to discharge. No between-group differences were detected in any of the outcome measures. Conclusion and Discussion. Visual feedback or conventional balance training in addition to regular therapy affords no added benefit when offered in the early stages of rehabilitation following stroke.

Abstract Background: Visual feedback from the center of pressure (COP) on the benefits of standing quietly remains controversial. The study was to investigate the adaptive effect of COP real-time visual feedback training provided by smart wearable devices on standing in silence. Methods: Thirty healthy female college students were randomly divided into three groups (visual feedback balance training group (VFT), non-visual feedback balance training group (NVFT) and control group (CG)) .Two force plates were used to calculate the coordinates of COP anteroposterior (COPAP) and COP mediolateral (COPML).The motion analysis system is used to calculate the coordinates of the center of mass in two directions. Enhanced visual feedback on the screen in the form of fluctuating in different directions, VFT received real-time visual feedback from Podoon APP for training, the NVFT only performs open eye balance without receiving real-time visual feedback. The CG group did not receive any visual feedback. The training lasted 4 weeks, the training lasts 30 minutes at an interval of 1 days. Results: After four weeks of balance training, the results showed that visual feedback training can improve the stability of human posture control by one leg stance and tandem stance static balance training on VFT intelligent App. The parameters of COPML/AP max displacement, COPML/AP velocity and COP radius and COP area in the VFT were significantly increased (p＜0.05).Conclusion: The conclusion shows that COP real-time visual feedback training provided by smart wearable devices can reduce postural sway better and improve body balance ability than general training when standing quietly.

Balance control with an upright posture is affected by many factors. This study was undertaken to investigate the effects of real-time visual feedback training, provided by smart wearable devices for COP changes for healthy females, on static stance. Thirty healthy female college students were randomly divided into three groups (visual feedback balance training group, non-visual feedback balance training group, and control group). Enhanced visual feedback on the screen appeared in different directions, in the form of fluctuations; the visual feedback balance training group received real-time visual feedback from the Podoon APP for training, while the non-visual feedback balance training group only performed an open-eye balance, without receiving real-time visual feedback. The control group did not do any balance training. The balance training lasted 4 weeks, three times a week for 30 min each time with 1–2 day intervals. After four weeks of balance training, the results showed that the stability of human posture control improved for the one leg static stance for the visual feedback balance training group with smart wearable devices. The parameters of COP max displacement, COP velocity, COP radius, and COP area in the visual feedback balance training group were significantly decreased in the one leg stance (p < 0.05). The results showed that the COP real-time visual feedback training provided by smart wearable devices can better reduce postural sway and improve body balance ability than general training, when standing quietly.

This study aims to explore the effect of real-time visual feedback (VF) information of the pres-sure of center (COP) provided by intelligent insoles on balance training in a one leg stance (OLS) and tandem stance (TS) posture. Thirty healthy female college students were randomly assigned to the visual feedback balance training group (VFT), non-visual feedback balance training group (NVFT), and control group (CG). The balance training includes: OLS, tandem Stance (dominant leg behind, TSDL), tandem stance (non-dominant leg behind, TSNDL). The training lasted 4 weeks, the training lasts 30 minutes at an interval of 1 days. There was a sig-nificant difference in the interaction effect between Groups*Times of the COP parameters (p&lt;0.05) for OLS. There was no significant difference in the interaction effect between Groups*Times of the COP parameters (p&gt;0.05) for TS. The main effect of the COP parameters was a significant difference in Times (p&lt;0.05). The COP displacement, velocity, radius, and area in VFT significantly decreased after training (p &lt; 0.05). Therefore, the visual feedback technology of intelligent auxiliary equipment during balance training can enhance the benefit of training. The use of smart wearable devices in OLS balance training may improve the visual and physical balance integration ability.

Frequency Stimulation

Electrotherapy is commonly used for myalgia alleviation. Low-frequency stimulation (LFS) is primarily used for controlling acute and chronic pain and is a non-invasive therapy that can be easily performed with electric stimulation applied on the skin. However, little evidence exists regarding the pain alleviation effects of personal low-frequency stimulation device for home use. Moreover, no studies have compared myalgia alleviation effects between personal low-frequency stimulation (PLS) and physical therapy (PT), which are most commonly used for patients with myalgia in hospitals and clinics. Therefore, we aimed to investigate the pain alleviation effects of PLS in patients with myalgia and compare these effects with those of conventional PT (transcutaneous electrical nerve stimulation + ultrasound). In total, 39 patients with myalgia in the neck, shoulder, back, and waist areas were randomly assigned to the personal low-frequency stimulation group (PLSG: n = 20) and physical therapy group (PTG: n = 19). Both groups were treated for 3 weeks (20 min per session and 5 sessions per week). Patients were assessed for pain intensity by surface electromyography (sEMG), visual analogue scale (VAS) and a short-form McGill pain questionnaire (SF-MPQ) before and after the intervention period. Our results showed that PLSG showed a tendency of muscle relaxation with a significant decrease in sEMG in the neck (p = 0.0425), shoulder (p = 0.0425), and back (p = 0.0046) areas compared to the control group. However, there was no significant difference in waist area. Additionally, VAS scores significantly decreased between pre- and post-treatment in both PTG (p = 0.0098), and PLSG (p = 0.0304) groups, but there was no significance difference between the groups. With respect to SF-MPQ, the PLSG showed greater pain alleviation (5.23 ± 0.25) effects than the PTG (6.23 ± 0.25). Accordingly, our results suggest that PLS treatment using a home device might offer positive assistance in pain alleviation for patients with myalgia that is as equally effective as conventional PT treatment. However, further detailed studies are required considering larger samples to fully claim the effectiveness of this device.

This study was conducted to investigate the effects of balance training with electromyogram-triggered functional electrical stimulation (EMG-triggered FES) to improve static balance, dynamic balance, and ankle muscle activation in stroke patients. Forty-nine participants (>6 months after stroke) were randomly assigned to the experimental group (n = 25) and the control group (n = 24). The experimental group underwent balance training with EMG-triggered FES for 40 min a day, 5 days a week, for a 6-week period in addition to general rehabilitation. The control group underwent balance training without EMG-triggered FES along with conventional therapy. Outcome measures included static balance ability, dynamic balance ability, and leg muscle activation. The static and dynamic balance abilities were significantly improved after intervention in both groups (p < 0.05), although the experimental group showed considerably greater improvement than the control group (p < 0.05). Leg muscle activation on the affected side resulted in significant improvements in the experimental group (p < 0.05) when compared with baseline but not in the control group. Balance training with EMG-triggered FES is an acceptable and effective intervention to improve the static balance, dynamic balance, and ankle muscle activation in stroke patients.

Objective: To explore the effects of an eight-week core stability program on balance ability in persons with Parkinson’s disease. Design: Randomized controlled trial. Setting: A local Parkinson’s association. Subjects: A total of 44 participants with a clinical diagnosis of Parkinson’s disease were randomly assigned to an experimental ( n = 22) or control group ( n = 22). Intervention: The experimental group received 24 sessions of core training, while the control group received an intervention including active joint mobilization, muscle stretching, and motor coordination exercises. Main measures: The primary outcome measure was dynamic balance evaluated using the Mini-Balance Evaluation Systems Test. Secondary outcomes included the balance confidence assessed with the Activities-specific Balance Confidence Scale and standing balance assessed by the maximal excursion of center of pressure during the Modified Clinical Test of Sensory Interaction on Balance and the Limits of Stability test. Results: After treatment, a significant between-group improvement in dynamic balance was observed in the experimental group compared to the control group (change, 2.75 ± 1.80 vs 0.38 ± 2.15, P = 0.002). The experimental group also showed a significant improvement in confidence (change, 16.48 ± 16.21 vs 3.05 ± 13.53, P = 0.047) and maximal excursion of center of pressure in forward (change, 0.86 ± 1.89 cm vs 0.17 ± 0.26 cm, P = 0.048), left (change, 0.88 ± 2.63 cm vs 0.07 ± 0.48 cm, P = 0.010), and right (change, 1.63 ± 2.82 cm vs 0.05 ± 0.17 cm, P = 0.046) directions of limits of stability compared to the control group. Conclusion: A program based on core stability in comparison with non-specific exercise benefits dynamic balance and confidence and increases center of mass excursion in patients with Parkinson’s disease.

9105 Background: It is well-documented that treatment side-effects cause physical and psychosocial de-conditioning in cancer patient. Decrease in functional performance (FP), as measured by activities of daily living (ADL), is a major contributor to a decline in patient quality of life (QOL). Relatively little information is available on the effects of a specific exercise regimen targeting muscle groups/energy systems involved in FP. Methods: 30 male and female cancer patients receiving treatment were randomly assigned to either the experimental (EX) or control (C) groups. EX participated in two exercise sessions per week for 17 weeks. Sessions included a combination of aerobic, resistance, flexibility, and balance training. C did not participate in any structured exercise. Data were collected post-diagnosis (1), post- surgery (2), at 9 weeks post-diagnosis (3), and at 17 weeks post-diagnosis (4). Measurements included resting heart rate (RHR), fatigue, physical activity level (PA), QOL, and the FP tasks of: treadmill walking (TRED), stair climb/descent (STAIR), lifting/carrying (CARRY), sit to stand (STAND), and balance (REACH). Results: Factor analysis yielded four variables: FP1 = [(0.5 × TRED) - (0.5 × RHR)]; FP2 = [(STAIR) + (CARRY) + (STAND)]/3]; FP3 = [(0.333 × QOL) + (0.333 × PA) - (0.333 × FT)]; FP4 = REACH. Repeated-measures ANOVA with within-subjects contrasts detected significant differences between groups. No significant differences existed at 1 or from 1 to 2. Significant differences were found on all variables from 1 to 4, 1 to 3 and 3 to 4 (p < 0.001) (significant improvement for experimental group vs. significant decline for control group). Mean changes for the experimental vs. control groups from 1 to 4 are as follows: FP1 (+65.5 vs. -29.5); FP2 (-5.3 vs. +3.6); FP3 (+1.8 vs. -3.4); FP4 (+1.7 vs. -0.81). Conclusions: Specifically-designed exercise interventions promote positive adaptations that elicit significant improvement in ADL, QOL, and decrease fatigue. Prescriptive exercise is a viable therapy during treatment for mitigating side effects and avoiding de-conditioning. No significant financial relationships to disclose.

The aim of this study was to compare the effects of dynamic balance exercises with and without visual feedback on recovery from total knee arthroplasty. The participants were 30 women who underwent total knee arthroplasty more than one week before the study, and were randomly allocated into two groups. The average ages of the experimental and control groups were 70.13 and 69.00 years, respectively. The dynamic balance exercise with visual feedback (VF) group practiced dynamic balance exercises using a laser pointer for five 30-min sessions over a 4-week period. The dynamic balance exercise without visual feedback (control) group practiced dynamic balance exercises for five 30 min sessions over a 4 week period. The following clinical measures were used for assessing physical function, balance ability, and depression. Compared with the control group, the VF group showed significant improvements in the physical performance test, Western Ontario and McMaster Universities Arthritis Index (WOMAC), confidence ellipse area (CEA), path length (PL), average velocity (AV), and Timed Up and Go test (TUG test) (p < 0.05). Furthermore, the VF group showed significant improvements in all post-surgery outcome measures compared with the pre-surgery values (p < 0.05). The above results indicated that the dynamic balance exercises based on visual feedback improved physical function and balance ability in patients following total knee arthroplasty, suggesting the need for effective rehabilitation programs for patients with total knee arthroplasty.

Objective: To investigate the effectiveness of Maitland’s joint mobilization and therapeutic exercises on the functionality of the hands in patients with systemic sclerosis. Design: Randomized controlled trial. Setting: Tertiary university hospital. Subjects: Twenty-four patients diagnosed with systemic sclerosis according to ACR/EULAR 2013 criteria; age ⩾18 years and Cochin Hand Functional Scale (COCHIN) score ⩾10. They were randomized to physical therapy group ( n = 12) or control group ( n = 12). Interventions: The physical therapy group received joint mobilization and undertook therapeutic exercises, twice a week, for 12 weeks, and received a booklet with information about the disease. The control group only received the booklet about the disease. Main measures: The primary outcome measure was functionality of the hands (COCHIN). The secondary outcomes measures were disability (SHAQ), pain (visual analogic scale), range of motion (HAMIS and Delta finger-to-palm), grip strength (JAMAR dynamometer), and quality of life (SF12). Results: Twenty-two patients were female, with a mean age of 47.4 ± 11.1 years and 18 had limited cutaneous form. The physical therapy group showed a decrease of 11.33 points in the COCHIN in comparison with the control group ( P = 0.09). There was a significant increase in range of motion by HAMIS (3.00 ± 1.48 vs 5.42 ± 2.64, P = 0.008), reduction in pain VAS (3.42 ± 2.78 vs 7.75 ± 2.53, P < 0.001), and increase in the physical component of SF12 (38.51 ± 9.60 vs 32.65 ± 9.10, P = 0.038). Conclusion: Maitland’s joint mobilization and therapeutic exercises improved the functionality of the hands, reduced pain in the hands and wrists, increased range of motion, and improved quality of life in patients with systemic sclerosis.

This study evaluated the one-year effect of physical therapy on pain and mandibular dysfunction associated with anterior disc displacement without reduction of the temporomandibular joint (closed lock). Forty-nine individuals were randomly assigned to either a physical therapy group [n = 23, mean age (SD) 34.7 (14.0) yrs] or a control group [n = 26, mean age 38.5 (15.1) yrs]. At baseline and after 3, 6, 12, 26, and 52 wks, pain and mandibular function were evaluated. All patients received extensive information about avoiding parafunctions and oral habits on all evaluation days. The physical therapy group received, in a 6-week period, 9 sessions of physical therapy, including joint mobilization, exercises, and massage, and the information on avoiding parafunctions and oral habits was repeated each time. All pain variables decreased, and all function variables increased significantly over time for both groups. The interaction between time and treatment group was not significant. Hence, physical therapy had no significant additional effect in patients with anterior disc displacement, without reduction, of the temporomandibular joint ( ClinicalTrials.gov number, CT01475630).
