Effect of the Dynamic Orthotic Garment on Postural Control, and Endurance in Children with Spastic Diplegic Cerebral Palsy: A Randomized Controlled Trial.

Purpose: To investigate the effect of dynamic orthotic garments (Thera togs) on foot pressure distribution, postural control, and endurance in children with spastic diplegic CP. Patients and Methods: This is a single-blind randomized controlled clinical trial involving 34 (8-10 years) with spastic diplegic CP. The control group received conventional physical therapy (CPT), whereas the study group received CPT in addition to wearing TheraTogs. We recorded foot pressure distribution, trunk control measurement scale, trunk position sense, Pediatric Berg Balance Scale (PBS), and six-minute walking distance (6MWD). Results: Both groups showed improvement. The study group had significant improvement in foot pressure distribution (p-value 0.003, 0.001, <0.001 for forefoot, midfoot, and rearfoot mean pressures respectively, and 0.005, <0.001, and 0.005 for forefoot, midfoot, and rearfoot peak pressures respectively), Pediatric balance scale, The trunk control measurement scale, and Trunk position sense (p-value < 0.001) and six-minute walking distance (p-value 0.029). Our data suggest that adding TheraTogs to conventional physiotherapy improves foot pressure, postural control, and endurance in children with spastic diplegic cerebral palsy. Conclusion: Both TheraTogs and conventional physical therapy corrected foot pressure distribution, trunk control, improved balance, and increased 6MWD in children with spastic diplegic CP but the improvement was more significant in TheraTogs group. Clinical Trial Registration: NCT05271149.

Ipsilateral versus contralateral static endurance- balance abilities among healthy college students.

Objectives: This study sought to determine the association and the difference, if any, between the levels of the contralateral and between the levels of the ipsilateral sides during static endurance-balance exercise. Methods: One hundred twelve healthy active- college students (55 females and 57 males) participated in this cross-sectional study. Each participant performed the contralateral (raising one arm and opposite-side leg) quadruped bird dog exercise and balanced in static condition. Side bridge exercise was performed from lying on your side then engaging your core muscles and lifting your upper body and hips off the ground, maintaining a straight line and holding this position as long as tolerated. Results: Wilcoxon signed rank test showed significant difference (p = 0.004) between the contralateral right and left quadruped bird dog but insignificant difference (p = 0.059) between the ipsilateral right and left side bridge endurance-balance exercises. Mann-Whitney U test showed that the holding time was significant across gender for the contralateral but was insignificant for the ipsilateral endurance-balance exercise. Mann-Whitney U test was insignificant (p > 0.05) between those being recreationally active or inactive. Kruskal-Wallis test revealed insignificant difference between body mass index categories. Spearman's rho correlation coefficient showed strong positive correlation equals 0.85 and 0.75 (p < 0.001) of the contralateral quadruped bird dog and the ipsilateral side bridge exercises respectively. Conclusions: A significant difference was observed for contralateral, while no significant difference was found for ipsilateral endurance-balance abilities. Therefore, clinicians and rehab specialist should consider these findings when assessing the endurance-balance abilities to properly devise appropriate exercise progression of different trunk stabilizers.

Clinical and histopathological responses to bee venom phonophoresis in treating venous and diabetic ulcers: a single-blind randomized controlled trial.

Introduction: Chronic venous and diabetic ulcers are hard to treat that cause patients long time of suffering as well as significant healthcare and financial costs. Purpose: The conducted study was to evaluate the efficacy of bee venom (BV) phonophoresis on the healing of chronic unhealed venous and/or diabetic foot ulcers Also, to compare the healing rate of diabetic and venous ulcers. Methodology: The study included 100 patients (71 males and 29 females) with an age range of 40-60 years' old who had chronic unhealed venous leg ulcers of grade I, grade II, or diabetic foot ulcers with type II diabetes mellitus. They randomly assigned into four equal groups of 25: Group A (diabetic foot ulcer study group) and group C (venous ulcer study group) who both received conservative treatment of medical ulcer care and phonophoresis with BV gel, in addition to group B (diabetic foot ulcer control group) and group D (venous ulcer control group) who both received conservative treatment of medical ulcer care and received ultrasound sessions only without BV gel. Wound surface area (WSA) and ulcer volume measurement (UVM) were used to assess the ulcer healing pre-application (P0), post-6 weeks of treatment (P1), and after 12 weeks of treatment (P2). In addition to Ki-67 immunohistochemistry was used to evaluate the cell proliferative in the granulation tissue of ulcers pre-application (P0) and after 12 weeks of treatment (P2) for all groups. Results: This research revealed a statistical significance improvement (p ≤ 0.0) in the WSA, and UVM with no significant difference between study groups after treatment. Regarding Ki-67 immunohistochemistry showed higher post treatment values in the venous ulcer group in comparison to the diabetic foot ulcer group. Conclusion: Bee venom (BV) provided by phonophoresis is effective adjuvant treatment in accelerating venous and diabetic foot ulcer healing with higher proliferative effect on venous ulcer.

Effect of extracorporeal shock wave therapy on spastic equinus foot in children with unilateral cerebral palsy.

Objectives: This study aims to investigate the effects of radial extracorporeal shock wave therapy on selective motor control, spasticity, gross motor function, and balance in children with unilateral cerebral palsy. Methods: This randomised controlled study recruited 34 children aged 7-9 with spastic unilateral cerebral palsy. They were randomly allocated to either the control or study group. Both groups undertook traditional exercises for 12 weeks. The study group received shock waves (one session/week) on the calf muscle (1500 shocks, frequency of 4 Hz, energy of 0.030 mJ/mm2). All children were evaluated at baseline and after 12 weeks using the Modified Ashworth Scale, a Biodex System 4 isokinetic dynamometer, dimensions D (standing) and E (walking) of the Gross Motor Function Measure - 88, the Trost Selective Motor Control test, and the single leg standing test. Results: Mixed analysis of variance and Mann-Whitney results showed significant improvement in eccentric peak torque, torque threshold angles, gross motor function, selective motor control, and balance in the study group compared with the control group (p < 0.05). Conclusions: Shock wave therapy may be a valuable instrument for reducing spasticity, improving the ability to isolate and control movement, and consequently, improving balance and gross motor function in children with unilateral cerebral palsy.

Level of disability and associated factors with musculoskeletal disorders among supermarket cashiers.

OBJECTIVES: This study aimed to determine the severity of symptoms and the level of disability or difficulty associated with MSDs in the neck, shoulders, upper limbs, lower back, and lower limbs as well as the factors associated with MSDs. MATERIAL AND METHODS: This investigation collected demographic, health (36-Item Short Form Survey [SF-36]), and occupational related-factors for supermarket cashiers through the administration of several questionnaires, including the Oswestry Disability Index (ODI), Disabilities of the Arm, Shoulder and Hand (DASH), Neck Disability Index (NDI), Lower Extremity Functional Scale (LEFS), and Numeric Rating Scale (NRS) for pain. RESULTS: One hundred ninety-three supermarket cashiers participated in this study. The mean scores for disability levels included NDI (M±SD 18.62±14.57), ODI (M±SD 20.74±13.89), DASH (M±SD 15.08±13.90), and LEFS (M±SD 63.06±14.24). Regression analyses demonstrated the existence of significant relationships between the experience of MSDs and several other factors, including the number of working days per week, the preferred working position, marital status and the need for awkward positions. CONCLUSIONS: The results indicate MSDs that signified a mild disability level among young participants. The number of working days per week, the preferred working position, the need to assume awkward positions, and marital status were significantly associated with MSDs. The findings indicated the need for preventive to avoid or minimize the prevalence of MSDs among supermarket cashiers. Int J Occup Med Environ Health. 2022;35(4):407-23.

Effects of behavioural therapy versus interferential current on bladder dysfunction in multiple sclerosis patients; a randomised clinical study.

OBJECTIVES: This study examines the effect of behavioural therapy (biofeedback) and interferential current on bladder dysfunction in multiple sclerosis patients. METHODS: Fifty patients with secondary progressive type multiple sclerosis (SPMS) suffering from bladder dysfunction were divided equally into two groups randomly. Group A (GA) received behavioural therapy (biofeedback training), while Group B (GB) received interferential current training. Both groups were assessed by urodynamics for detrusor pressure and maximum flow rate before and after eight weeks of behavioural therapy and interferential training. RESULTS: Both groups, GA and GB, showed significant increase in the detrusor pressure and maximum flow rate after eight weeks of training. There was no significant difference between both methods. However, GA showed more improvement by close observation. CONCLUSIONS: Both behavioural therapy and interferential current training effectively managed bladder dysfunction in patients with SPMS, with more evident effects in behavioural therapy patients by close observation.

Effect of Low Versus High-Heeled Footwear on Spinopelvic Alignment at Different Phases of Menstrual Cycle in Young Adult Women: A Biopsychosocial Perspective.

High-heeled shoes adversely affect spinal curvature, increase the risk of low back pain, and disturb the normal gait pattern. The purpose of this study was to examine, from a biopsychosocial point of view, the combined effect of wearing two different heel heights and of hormonal oscillation throughout different phases of the menstrual cycle on spinopelvic alignment. Notably, 70 females with an average age of 20.42 ± 1.51 years participated in this study, wearing each female two different heel heights as follows: low (2.5 cm) and high (7 cm). Spinopelvic alignment was evaluated by rasterstereography formetric 3D analysis during early follicular, ovulatory, and mid-luteal phases of the menstrual cycle. Statistical analysis showed that there was no significant difference (p > 0.05) on spinopelvic alignment [kyphotic angle (KA), trunk inclination (TI), and pelvic inclination] between wearing low- or high-heeled shoes during early follicular, ovulatory, and mid-luteal phases of the menstrual cycle. Considering that high-heeled shoes are traditionally associated with femininity, body image, beauty, and charm, this research has important biopsychosocial implications that should be explored in detail in future studies.

Isokinetic trunk muscle performance in adolescents with different body mass indices.

OBJECTIVE: This study aims to evaluate the isokinetic performance for the peak torque and average power of the spinal flexor and extensor muscles in adolescents aged 12 to 18 years. The study also analyses the differences between the trunk muscle peak torque and average power with body mass index (BMI). METHOD: The peak torque and average power of the trunk flexor and extensor muscles were measured in 180 adolescents (aged 12-18 years). The participants were classified into four groups according to BMI. The Biodex isokinetic dynamometer in concentric mode at speeds of 60° and 120°/sec was used for assessment. RESULTS: One-way multivariate analysis of variance MANOVA results demonstrated a significant difference in trunk muscle peak torque and average power with different BMI (F = 14.692, p = 0.0005). A Pearson's correlation analysis demonstrated a significantly negative correlation between weight and peak torque of trunk flexors and extensors (r = - 0.43, p = 0.0001; r = -0.31, p = 0.007, respectively). Finally, the results showed a negative correlation between weight and average power of trunk flexors and extensors (r = -0.54, p = 0.0001; r = -0.31, p = 0.007). CONCLUSION: In this study, overweight and obese adolescents are found to be correlated with decreased trunk muscle torque and power. Thus, therapeutic interventions for overweight and obese adolescents, along with exercise training programmes, may help improve muscle performance including peak torque and power. Finally, these measures may enhance the quality of life of such adolescents.

Self-Reported Musculoskeletal Disorders and Quality of Life in Supermarket Cashiers.

Supermarket cashiers face a significant amount of stress, including time constraints, mental pressure, and physical demands that require repetitive movements. The job description of a supermarket cashier involves work-related risk factors that may lead to musculoskeletal disorder (MSD) symptoms. This study aimed to investigate supermarket cashiers to determine the prevalence of MSD symptoms and their quality of life. Data were collected from a convenience sample of supermarket cashiers working in Saudi Arabia. Information included direct questions on pain in the previous 12 months, demographic data, and health- or occupation-related factors. Moreover, data was collected based on the 36-item short form survey (SF-36), and descriptive statistics were computed. A total of 193 supermarket cashiers participated in this study. The sample included 140 men (72.5%) and 53 women (27.5%), with a mean age of 27.2 ± 6.4 years. The majority of the participants (90%) had MSD symptoms in at least one body region, with the neck (66.84%) and lower back (65.80%) constituting the most prominent regions. The mean SF-36 scores were higher in participants without pain compared to participants with pain in all domains, except for the physical functioning domain. The high prevalence of MSD symptoms among young cashiers suggest the need for additional investigations to determine the risk factors of these disorders. Additionally, this study recommends preventive procedures to reduce the prevalence of MSD symptoms among cashiers.

Peak torque substantially varies between patients with non-specific low back pain; belong to directional preference classification, and healthy individuals-clinical biokinesiologic perspectives.

[Purpose] To compare flexion and extension peak torque of patients with nonspecific-chronic low back pain who were classified as directional preference subgroups, and their matched healthy controls. [Participants and Methods] Fifty male volunteers (25 with non-specific chronic low back pain and 25 healthy-matched controls) consented to participate. The investigator collected all demographic data, hips, knees and spinal mobility in addition to the peak torque using the Biodex isokinetic dynamometer. The measurement protocol consisted of 2 sets of 10 consecutive flexion-extension efforts performed at 120°/sec and 60°/sec angular velocity. A two minutes rest period was given between sets. The preset 50° range of motion included 20°(+20°) of trunk extension and 30°(-30°) of trunk flexion. [Results] A 2 × 2 mixed-design ANOVA showed a significant group X isokinetic velocity interaction. The main effect of isokinetic velocity was also significant. In reference to the peak torque of the flexors of the trunk, the main effect of group was significant. [Conclusion] The extension peak torque significantly depends on the velocity of the isokinetic dynamometer; however the flexion peak torque significantly depends on the participants' group attribution.

Clinical measurements of spinal mobility, static balance, and functional performance in healthy participants: a simple biokinesiological analysis of performance.

[Purpose] To explore the relationship between functional outcome measurements of spinal mobility, static balance and functional performance. [Participants and Methods] Fifty two healthy participants aged between 18-36 years participated. Spinal mobility included forward bending and side bending. Balance was tested via maintaining single-leg stance position with eyes open and with eyes closed. Functional testing included five times squat to stand, walking on heels and walking on tiptoes. [Results] Two-way mixed intraclass correlation coefficients (ICCs) consistency model average measure (ICC3,K) for single-leg standing with the eyes are open and closed was excellent (0.85) and very good (0.79) respectively. Mean forward spinal mobility score of the recreationally active group (M= 3.3 ± 5.7) was significantly lower (M= 9.5 ± 10.5) than inactive group. Regarding five times squat to stand, the mean score of the recreationally active group (10.4 ± 4.3) was not significantly different from the mean of the recreationally inactive group (9.5 ± 2.6). [Conclusion] Walking on heels significantly took more time and perceived with more exertion than tiptoes walking. Also, standing on one leg was harder when eyes are closed. Recreationally active had shown significant forward mobility but no difference between sidebending mobility. The relationships between different outcome measures need to be furtherly explored.

Effect of cardiac surgery on respiratory muscle strength.

OBJECTIVES: Pulmonary complications, such as atelectasis, pulmonary oedema, pleural effusion, bronchospasm, and pneumonia, have been reported following cardiac surgery. Shallow breathing leading to impaired lung function is the major cause of respiratory complications. Decreases in respiratory muscle strength can be measured using the maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) produced in the oral cavity. This study aimed to determine the decrease in respiratory muscle strength 8 weeks following cardiac surgery. Moreover, the relationship between lung function and respiratory muscle strength was studied. METHODS: In this observational study, 42 adult cardiac surgery patients (10 women, 32 men; mean age 65 ± 7 years) were investigated. Lung function and respiratory muscle strength were measured preoperatively and at 2 months postoperatively. RESULTS: The pre- and postoperative respiratory muscle strengths were in accordance with the predicted values. The MIP was 81.75 ± 22.04 cmH2O preoperatively and 74.56 ± 18.86 cmH2O at the 2-month follow-up (p = 0.146). The MEP was 98.55 ± 22.24 cmH2O preoperatively and 88.86 ± 18.14 cmH2O at the 2-month follow-up (p = 0.19). The preoperative lung function was in accordance with the predicted values; however, lung function significantly decreased postoperatively. At the 2-month follow-up, there was a moderate correlation between the MIP and forced expiratory volume (r = 0.59, p = 0 .0078). CONCLUSIONS: The respiratory muscle strength was not impeded either before or 2 months after cardiac surgery. However, the exact mechanism for the alteration in lung function remains unclear. Measures to re-establish the ideal postoperative lung capacity should concentrate on different perioperative pulmonary exercises.

Assessment of hand-grip and key-pinch strength at three arm positions among healthy college students: Dominant versus non-dominant hand.

OBJECTIVE: Grip strength is important for independent self-care and is a predictor of functional decline. This study aimed to determine if healthy individuals would demonstrate different hand-grip and key-pinch strengths at three different arm positions and in comparisons between dominant and non-dominant hands. METHODS: A total of 61 right-hand-dominant male college students aged 19-23 years were consecutively recruited from the College of Medical Rehabilitation Sciences. Three researchers performed the measurements. All tests were performed with the JAMAR® hand-grip dynamometer handle set in its second position. Participants were instructed to squeeze the handle of the hand-grip dynamometer in the 90° elbow flexion, 90° shoulder flexion, and arm dangled positions. For assessment of key-pinch strength, every participant had to squeeze the thumb pad against the lateral aspect of the middle phalanx of the index finger. Key-pinch strength was measured in the same positions used for assessment of hand-grip strength. Participants were blinded for the outcome measurements. The significance level was set at p < 0.05. RESULTS: The hand-grip and key-pinch strengths did not show significant effects. Comparison of right and left hand-grip strengths also showed insignificant differences. However, the key-pinch strength showed a significant increase in favour of the dominant hand. CONCLUSIONS: Clinicians can choose any upper-extremity position to measure hand-grip and key-pinch strength. Furthermore, clinicians should aim to maintain and restore almost equal scores for hand-grip and pinch strength of the dominant and non-dominant hands to ensure better hand function.

Incidence of First Time Stroke: A Saudi Experience.

BACKGROUND: Stroke is one of the major causes of morbidity and mortality throughout the world. A number of studies were conducted in Saudi Arabia. However, there were no studies conducted in Al-Madinah Al-Munawarah city. OBJECTIVE: The aim of this study was to ascertain the incidence rate of first time stroke and the age-specific incidence in both genders in Al-Madinah Al-Munawarah city. METHODS: A prospective hospital based study was conducted over a 1-year period (2014). The cases were included in the study when they were admitted with a diagnosis of cerebrovascular accident. RESULTS: A total 164 patients (91 men and 73 women) who had first time stroke were found in this study with no significant difference between them (p = 0.565). The crude incidence rate of stroke was 13.89 per 100,000 persons. The age-specific incidence rate increased with age in the current study, where the peak was in the age group of more than 75 years old for men and women. CONCLUSIONS: Total crude and the age-specific rates for first time stroke patients revealed in this study were markedly lower than the range reported from the developed countries. However, they were within the range that showed previously in Saudi Arabia and Arabian Peninsula countries.

Effect of a short term pulmonary rehabilitation programme on exercise capacity, pulmonary function and health related quality of life in patients with COPD.

OBJECTIVES: Patients with chronic obstructive pulmonary disease (COPD) have been shown to benefit from pulmonary rehabilitation programmes. The purpose of this study was to ascertain the effects of a short-term pulmonary rehabilitation programme (PRP) on exercise capacity, pulmonary function and quality of life in patients with COPD. METHODS: A pre-test and post-test experimental design was conducted on patients from the outpatient physical therapy department. Thirty stable COPD patients with mild to severe airflow obstruction, (mean age 54.1 ± 5.22, FEV1, between 0.80 and 0.30 predicted; FEV1/FVC < 0.70) were recruited for a 6-week comprehensive pulmonary rehabilitation programme (PRP) that included education and exercise training. Exclusion criteria included the following: cardiovascular conditions likely to be aggravated by exercise, locomotor impairment, haemoptysis, cognitive impairment, severe pulmonary hypertension, and metastatic cancer. The patients were randomly divided into experimental and control groups. RESULTS: Six-minute walk distance (6MWD), pulmonary function (FEV1, FVC, FEV1/FVC), and St. George's Respiratory Questionnaire (SGRQ) scores were measured at baseline, at the end of the 3rd week and at the end of the 6th week. The results showed significant improvements in 6MWD and SGRQ (p < 0.05). CONCLUSION: A 6-week outpatient-based PRP significantly improves exercise capacity and quality of life, irrespective of the degree of airflow obstruction.

The use of phototherapy in peripheral nerve regeneration: an updated critical review.

This review describes the possible factors that may have contributed to the variability of the results between studies that have assessed the effects of phototherapy on peripheral nerve regeneration. Furthermore, it aims to make recommendations to overcome the methodological shortcomings identified. A search of the literature was conducted. In vitro and in vivo experimental studies and clinical trials were included. Twenty five studies were critically reviewed and showed considerable variability in irradiation parameters, techniques, approaches, length of irradiation courses, experimental injury tools and procedures. Many studies that have investigated the use of phototherapy in nerve regeneration produce positive results. However, the majority of these studies suffered from a number of shortcomings: no evidence of blinding and/or randomizing procedures, lack of specification of irradiation parameters, unspecified and/or inadequate tests in their experimental injury procedures, inappropriate irradiation parameters and/or poor experimental conditions.

Test-retest reliability of myofascial trigger point detection in patients with rotator cuff tendonitis.

OBJECTIVES: To investigate the test-retest reliability of the following clinical diagnostic characteristics of myofascial trigger points: taut band, spot tenderness, jump sign, pain recognition, referred pain and local twitch responses (LTRs). DESIGN: Test-retest reliability study. SETTING: This study was undertaken in an outpatient physiotherapy department. SUBJECTS: Fifty-eight patients (31 males and 27 females) with rotator cuff tendonitis were recruited into this study. INTERVENTION: Rotator cuff muscles were assessed by an expert for the presence or absence of the main clinical diagnostic characteristics of trigger point assessment. The process was then repeated three days later by the same expert. MAIN MEASURES: Outcomes included the presence or absence of: a taut band, spot tenderness, jump sign, pain recognition, referred pain and LTRs. RESULTS: Kappa values between testing situations for the taut band, spot tenderness, jump sign and pain recognition were 1. Kappa scores for referred pain ranged between 0.79 and 0.88 and for the local twitch response between 0.75 and 1 depending on the muscles under investigation. CONCLUSIONS: The presence or absence of the taut band, spot tenderness, jump sign and pain recognition was highly reliable between sessions. Referred pain and local twitch response reliability varied depending on the muscle being studied.
