Turk J Phys Med Rehabil 2023; 69:479-487. [PMID: 38766579 PMCID: PMC11099859 DOI: 10.5606/tftrd.2023.11875] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Accepted: 04/14/2023] [Indexed: 05/22/2024] Open
Abstract
Objectives This study aimed to investigate the effect of Tecar therapy on neuropathy symptoms and tibial nerve conduction velocity in individuals with diabetes. Patients and methods The single-blind, randomized, sham-controlled clinical trial was conducted between January 2019 and October 2019. Twenty-four type 2 diabetics (8 males, 16 females; mean age: 60.4±8.9 years; range, 40 to 78 years) with peripheral neuropathy were randomly allocated to control (n=12) and study (n=12) groups. The study group received the capacitive Tecar therapy with 10 to 30% intensity and infrared radiation in 10 sessions. The controls received the same protocol with zero intensity. The neuropathy symptoms and nerve conduction velocity were evaluated at baseline, after 10 sessions, and six weeks after the end of sessions. Results There were no significant differences in variables (p>0.05). In this way, the homogeneity of the data variables was confirmed. Moreover, the results of two-way mixed analysis of variance showed that improvement of neuropathy symptoms in the study group was significantly more than controls in all stages (p<0.001). After 10 sessions, the results of post hoc analysis showed that the neuropathy symptoms and tibial nerve conduction velocity were significantly improved in both groups (p<0.05). However, there was no change in these outcomes after six weeks in the control group (p>0.05). Conclusion Tecar therapy could improve neuropathy symptoms and tibial nerve conduction velocity in diabetic individuals with peripheral neuropathy. Therefore, the use of this method to control the symptoms of diabetic patients can be recommended.

Comparing the effectiveness of flexi-bar and stability exercises on postural control in chronic nonspecific low back pain: A randomized controlled study. Turk J Phys Med Rehabil 2023; 69:510-519. [PMID: 38766585 PMCID: PMC11099866 DOI: 10.5606/tftrd.2023.10726] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Accepted: 10/25/2022] [Indexed: 05/22/2024] Open
Abstract
Objectives This study aimed to compare the effect of flexi-bar and stabilization exercises on static and dynamic postural control in patients with chronic nonspecific low back pain. Patients and methods In this randomized controlled study conducted between November 2019 and March 2020, 38 patients (19 males, 19 females; mean age: 33.8±6.2 years; range, 20 to 45 years) were randomly assigned into flexi-bar (n=19) and stabilization (n=19) groups. Both groups received general physiotherapy for three sessions per week, a total of 10 sessions. Besides, the flexi-bar group received flexi-bar exercises, and the stabilization group received stabilization exercises. Postural sway was assessed with a force platform in three difficult conditions, including open eye, close eye, and one-leg standing and dynamic posture with the modified Star Excursion Balance Test. Results After the intervention, both groups showed a significant improvement in static and dynamic postural control (p<0.05). However, no significant differences were found between groups after treatment, while only the phase-plane portrait of opened eyes condition was significantly improved (p=0.03), in the flexi-bar group compared to the stabilization group. Conclusion Both flexi-bar and stabilization exercises effectively improved static and dynamic postural control, but none of the exercises was superior to the other. Flexi-bar is recommended as an effective tool in low back pain rehabilitation.

Comparison of 4 weeks of cupping and Kinesio-taping on clinical and ultrasound outcomes of carpal tunnel syndrome during pregnancy. J Bodyw Mov Ther 2023; 35:57-63. [PMID: 37330803 DOI: 10.1016/j.jbmt.2023.04.048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2021] [Revised: 01/16/2023] [Accepted: 04/12/2023] [Indexed: 06/19/2023]
Abstract
OBJECTIVE To explore effect of cupping and Kinesio-taping techniques on clinical and ultrasound outcomes of carpal tunnel syndrome (CTS) during pregnancy. METHODS Thirty pregnant women suffering from CTS were randomly assigned into Kinesio-taping (n = 15) and cupping (n = 15) groups. In Kinesio-taping group, individuals underwent Kinesio-taping for three days, one day with no treatment, and three days with Kinesio-taping, continuing this procedure for four weeks. In cupping group, cupping was moved for 5 min with pressure of 50 mm-Hg on the carpal tunnel area. This procedure continued longitudinally in forearm area for 2 min. The therapeutic intervention of cupping group continued with eight sessions, two days a week for 4 weeks. Ultrasound outcomes including median nerve cross-sectional area through ultrasonography, and clinical outcomes including pain through visual analog scale and severity of symptoms and functional status through Boston questionnaire were measured in both groups before and after therapeutic program. RESULTS In both groups, a significant reduction was observed in all variables after treatment compared to pre-treatment (P < 0.001). In inter-group comparison, a significant improvement was found in outcomes of Boston questionnaire and ultrasound results about median nerve cross-sectional area at pisiform and hook of hamate in cupping group compared to Kinesio-taping at end of four weeks (P < 0.001). CONCLUSION Both cupping and Kinesio-taping improved clinical and ultrasound outcomes of CTS. However, efficacy of cupping compared to Kinesio-taping was better in improvement of median nerve cross-sectional area at hamate hook and pisiform levels, symptoms severity scale, and functional status scale, which makes the results clinically more applicable.

[PMID: 37252218 PMCID: PMC10225034 DOI: 10.18502/jthc.v18i1.12580] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Accepted: 12/09/2022] [Indexed: 05/31/2023] Open
Abstract
Background The long-term effects of aerobic exercise on the cardiorespiratory system have been studied extensively. This study aimed to evaluate the effects of aerobic exercise with and without external loads on blood glucose, cardiovascular, respiratory, and body temperature indices in patients with type II diabetes. Methods The present randomized control trial recruited participants from the Diabetes Center of Hamadan University through advertisement. Thirty individuals were selected and divided into an aerobic exercise group and a weighted vest group via block randomization. The intervention protocol included aerobic exercise on the treadmill (0 slopes) with an intensity of 50% to 70% of the maximum heart rate. The exercise program for the weighted vest group was identical to that of the aerobic group, except that the subjects wore a weighted vest. Results The mean age of the study population was 46.77±5.11 years in the aerobic group and 48±5.95 years in the weighted vest group. After the intervention, blood glucose in the aerobic group (167.07±72.48 mg/dL; P<0.001) and the weighted vest group (167.75±61.53 mg/dL; P<0.001) was decreased. Additionally, resting heart rate (aerobic: 96.83±11.86 bpm and vest: 94.92±13.65 bpm) and body temperature (aerobic: 36.20±0.83 °C and vest: 35.48±0.46 °C) were increased (P<0.001). Decreased systolic (aerobic: 117.92±19.27 mmHg and vest: 120.91±12.04 mmHg) and diastolic (aerobic: 77.38±7.54 mmHg and vest: 82.5±11.32 mmHg) blood pressure and increased respiration rate (aerobic: 23.07±5.45 breath/min and vest: 22±3.19 breath/min) were seen in both groups but were not statistically significant. Conclusion One aerobic exercise session with and without external loads reduced blood glucose levels and systolic and diastolic blood pressure in our 2 study groups.

Abstract
Background/aims Older adults with different physical activity levels have often demonstrated individual differences in motor performance and learning. Serial reaction time task training and anodal transcranial direct current stimulation of the primary motor cortex were used in this study to evaluate how these interventions affected motor learning in older adults with low activity levels. Methods In this randomised controlled trial, 28 healthy, right-handed, older adults with low activity levels, with a mean age of 69.92 years, were randomly allocated to an anodal transcranial direct current stimulation group (n=14) or sham transcranial direct current stimulation group (n=14), based on a simple non-probability sampling method. The experimental group was exposed to 20 minutes of anodal transcranial direct current stimulation of the motor cortex, using a tDCS device, alongside eight sequenced or randomised blocks of serial reaction time task activities, for 5 consecutive days. In the control group, the tDCS device was automatically switched off after 1 minute. To assess implicit motor learning, the response time and error rate of two sequenced blocks of serial reaction time task activities were collected before, immediately following, 1 day and 1 week after the completion of the intervention. Results Immediately following the end of the intervention, at day 5, the mean response time and error rate were 925.09 and 2.55 in the experimental group, and 1016.52 and 4.10 in the control group. At 1 day after the completion of the intervention, the mean response time and error rates were 927.40 and 3.03 in the experimental group and 1021.91 and 4.34 in the control group. At 1 week after the completion of the intervention, the mean response time and error rates were 942.26 and 3.63 in the experimental group and 1050.08 and 5.11 in the control group. These findings indicate that response time and error rate were significantly decreased in both stimulation groups at different time points (P<0.001). At the same time, there were no significant differences in the response time and error rate between the two groups at different time points: immediately (P=0.07, P=0.31), 1 day (P=0.06, P=0.41) and 1 week (P=0.04, P=0.35) after the completion of the intervention respectively. Conclusions Serial reaction time task training, with or without applying anodal transcranial direct current stimulation, can improve motor learning in low-activity older adults. Therefore, it appears that anodal transcranial direct current stimulation did not affect or improve motor learning in older adults with low motor activity. Motor learning training can be used alone as a practical and helpful intervention to improve performance and implicit motor skill learning with long-lasting effects in older adults with low levels of activity.

[PMID: 33553048 DOI: 10.1007/s40200-020-00652-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Revised: 09/29/2020] [Accepted: 10/01/2020] [Indexed: 12/20/2022]
Abstract
Purpose Diabetic peripheral neuropathy (DPN) leads to decreased sole sensation and balance disorder, all of which increase the risk of falls and socioeconomic costs. Since the physiotherapists do not use the same manner to lessen the complications of this problem. Therefore, this review study was directed to appraise physiotherapy intervention efficiencies in diminishing DPN's symptoms and complications. Method A database search of Pubmed, Elsevier, Google Scholar, and Embase was performed to determine DPN's published documents. Finally, studies of DPN and treatments available in this field, particularly physiotherapy that included electrotherapy, exercise therapy, and other therapies, were identified. Result According to a database search on August 1, 2019, from 1989 to 2019, in the last 30 years, about 968 articles were found, 345 of which were free full text available, and finally, 19 articles were approved. These articles examined the effects of physiotherapy interventions, including exercise therapy, electrotherapy, and other treatment techniques on DPN patients. Conclusions The results showed that most diabetic peripheral neuropathy patients suffer from muscle weakness, pain, loss of balance, and lower limb dysfunction. As a result, their daily activity and Life satisfaction are gradually impaired. Exercise therapy, electrotherapy, and other physiotherapy methods have been used to reduce the mentioned cases. Among these interventions, exercise therapy has been the most effective. Although there was little evidence of aerobic exercise in these patients, further studies should be done on other therapies' effects.

Abstract
OBJECTIVES The Flexi-Bar and Bodyblade are oscillatory tools used in rehabilitation centers worldwide to enhance muscle activity. Because of a lack of reports on the Flexi-Bar, this study focused on erector spinae (ES) muscle activation under different conditions. METHODS Twelve university students (age 21 ± 2.5 years old) were recruited in this study and were tested while using a loaded Flexi-Bar for 10 seconds. Comparison between muscle activation on the right and left sides in the cervical, thoracic, and lumbar regions was measured by electromyography during two-leg and one-leg (left and right) standing. RESULTS The results showed that during oscillation using the right hand, the right cervical muscles showed significantly higher activation levels than the left cervical muscles, while the thoracic and lumbar regions showed significantly higher muscle activities on the left side. CONCLUSION The current study showed that the Flexi-Bar might be used for muscle activation and reeducation, as well as for specific exercise therapy in spinal muscle imbalance.

Abstract
Background: Diabetes is a chronic disease that reduces cardiorespiratory fitness and increases systolic and diastolic blood pressures as well as resting heart rate due to the activity level of the sympathetic nervous system. The aim of this study was to assess the effectiveness of 2 types of aerobic exercise, with and without external loading, on cardiac parameters in diabetic patients. Methods: This randomized controlled trial was carried out on 45 volunteers. These individuals were randomly divided into aerobic, weighted vest, and control groups. The aerobic protocol comprised 24 sessions of aerobic exercise. The exercise program for the weighted vest group was identical to that of the aerobic group, except that the subjects wore a weighted vest. The parameters were measured before and after the 24 sessions. Results: The mean age of the study population was 48.30±5.02 years in the aerobic group, 48.33±5.74 years in the weighted vest group, and 48.60±4.79 years in the control group. Males comprised 7 (53.8%) patients in the aerobic group, 7 (58.3%) in the weighted vest group, and 8 (53.3%) in the control group. After 8 weeks, maximum oxygen consumption in the aerobic group (mean±SD=37.54±8.02 mL/kg/min, 95% CI: 5.48 to 11.60; P<0.001) and the weighted vest group (mean±SD=35.92±3.96 mL/kg/min, 95% CI: 4.36 to 9.64; P<0.001) was increased, similar to metabolic equivalent of task in the aerobic group (mean±SD=11.60±1.62 kcal/kg×h, 95% CI: 1.48 to 2.72; P<0.001) and the weighted vest group (mean±SD=11.21±1.11 kcal/kg×h, 95% CI: 1.23 to 2.28; P<0.001). Furthermore, resting heart rate decreased significantly in the aerobic group (mean ± SD=90.23±8.90 bpm, 95% CI: -13.93 to -1.29; P=0.022) and the weighted vest group (mean±SD=90.58±9.19 bpm, 95% CI: -0.16 to - 12.33; P=0.045). Conclusion: These findings suggest that 24 aerobic exercise sessions might improve cardiac parameters in type 2 diabetes.

Abstract
OBJECTIVE The main objective of the present study was to analyze how supra spinal motor control mechanisms are altered in different directions during anticipatory postural phase of gait initiation in chronic ankle instability patients. It seems that supra spinal pathways modulate anticipatory postural adjustment phase of gait initiation. Yet, there is a dearth of research on the effect of chronic ankle instability on the anticipatory postural adjustment phase of gait initiation in different directions. METHOD A total of 20 chronic ankle instability participants and 20 healthy individuals initiated gait on a force plate in forward, 30° lateral, and 30° medial directions. RESULTS According to the results of the present study, the peak lateral center of pressure shift decreased in forward direction compared to that in other directions in both groups. Also, it was found that the peak lateral center of pressure shift and the vertical center of mass velocity decreased significantly in chronic ankle instability patients, as compared with those of the healthy individuals. CONCLUSION According to the results of the present study, it seems that chronic ankle instability patients modulate the anticipatory postural adjustment phase of gait initiation, compared with healthy control group, in order to maintain postural stability. These changes were observed in different directions, too.

Abstract
OBJECTIVE To investigate the immediate effect of electrical stimulation of the common peroneal nerve on the maximum voluntary activation of the quadriceps muscle in patients with knee osteoarthritis. METHODOLOGY Fifteen subjects with knee osteoarthritis (mean age: 50.5 ± 13 years) participated in this study. To measure the arthrogenic inhibition ratio of quadriceps, a burst of electrical stimulation was superimposed on the maximum voluntary contraction, and the percentage of change in the force production was computed. The same measurement was also performed with concurrent electrical stimulation of the common peroneal nerve. RESULTS All the patients with knee osteoarthritis showed significant arthrogenic inhibition of the quadriceps muscle. The stimulation of the common peroneal nerve was able to reduce this inhibition and increase the capacity of the muscle to produce a significantly higher knee extension force (p = 0.028). CONCLUSIONS Electrical stimulation of the common peroneal nerve concurrent with the maximum voluntary effort can remove the arthrogenic inhibition of the quadriceps muscle in patients with knee osteoarthritis. This finding could have clinical implications in the management of patients with knee disorders.

Abstract
OBJECTIVE Craniocervical (CC) muscles control posture of the CC area. Muscle imbalance at this area induces musculoskeletal disorders. The purpose of this study was to develop a device for measuring isometric force of CC flexor and extensor muscles and to evaluate its intra-rater reliability. METHOD Isometric force of CC flexor and extensor muscles was measured in 20 women by one examiner on two days with a custom-made device. The intra-class correlation coefficient (ICC), standard error of measurements (SEM), smallest detectable difference (SDD), and Pearson correlation coefficient were computed. RESULTS The results of this study revealed that this device had excellent reliability (ICC: 0.98, SEM: 2.29 N, SDD: 6.36 N, Pearson correlation coefficient: 0.97 for CC flexor muscles and ICC: 0.97, SEM: 2.13 N, SDD: 5.91 N, Pearson correlation coefficient: 0.94 for CC extensor muscles). DISCUSSION This new device can improve knowledge about the CC muscle and efficacy of treatments in patients with poor posture.

Abstract
OBJECTIVE The stability of the craniocervical (CC) area is provided by CC muscles. Muscle imbalance between forces of these muscles may lead to forward head posture (FHP). FHP is one of the most prevalent abnormal postures in patients with neck pain. The aim of the present study was to compare isometric force of the CC flexor and extensor muscles between women with and without FHP. METHOD Isometric force of the CC flexor and extensor muscles was measured by a custom-made device and compared between 70 women with and without FHP (35 in each group). RESULTS No significant difference was observed between the two groups regarding isometric force of the CC flexor and extensor muscles, but the ratio of the isometric force of the CC muscles (flexor to extensor) revealed significant difference between the two groups, and it was greater in the control group compared with that in the FHP group. DISCUSSION The ratio of isometric force of the CC muscles (flexor to extensor) may be a good indicator for assessment of patients with FHP. This ratio may also be valuable to follow the results of therapeutic intervention for these patients.

Abstract
OBJECTIVE To investigate the effects of base of support (BOS) and external loads on electromyographic (EMG) onset in the shoulder muscles during push-up exercises. METHODS Two levels of external load were applied at two levels of BOS stability during push-up exercises. EMG onset in six shoulder muscles was measured in 30 healthy participants. RESULTS With load set at 4% of body weight (BW), EMG onset in the lower trapezius (LT) (P = 0.003) and biceps brachia (BB) (P = 0.001) was significantly decreased with no load. Conversely, in other muscles (the upper trapezius (UT), teres major (TM), seratus anterior (SA) and deltoid posterior (DP)), time to EMG onset did not change significantly. No significant changes in EMG onset were observed with load at 2% of BW. The average time to EMG onset was significantly decreased for different stages of BOS instability in the LT (P = 0.04) and UT (P = 0.001). CONCLUSION Both load and BOS instability reduce time to EMG onset, but BOS instability produces greater reductions.
