Adolescents with hemophilic knee arthropathy can improve their gait characteristics, functional ability, and physical activity level through kinect-based virtual reality: A randomized clinical trial

Background

Hemophilic arthropathy is caused by recurrent intra-articular bleeding, most commonly in the knee joints. In terms of physical impact, this arthropathy causes significant disability and hampers the physical activity and functionality of he affected individuals.

Objective

This study intended to examine the effect of a physical rehabilitation program incorporating Kinect-based virtual reality (KBVR) on gait characteristics, functional ability, and physical activity level in adolescents diagnosed with hemophilic knee arthropathy (HKA).

Materials and methods

In a randomized clinical trial, 56 boys, aged 10-14 years, with moderate HKA, were randomly allocated into two groups. The control group (n = 28) received conventional physical therapy (CPT), while the KBVR group (n = 52) received a 30-min KBVR exercise program in addition to the CPT. Training was conducted three times/week for 12 successive weeks. Gait characteristics (step length, cadence, velocity, peak knee extension moment during stance, and knee flexion amplitude during swing) were assessed using a gait analysis system, the functional ability was assessed through the 6-min walk test, and physical activity level assessed by the Adolescents' Physical Activity Questionnaire on the pre- and post-treatment occasions.

Results

The KBVR group achieved more favorable changes in the gait characteristics [step length (P = 0.015), cadence (P = 0.004), velocity (P = 0.024), peak knee extension moment during stance (P = 0.018), and Knee flexion amplitude during swing (P = 0.032)], functional capacity (P = 0.002), and physical activity levels (P = 0.007) compared to the control group.

Conclusion

The use of KBVR exercises within a rehabilitation program is a potentially effective therapeutic option for the total care of adolescents with HKA.

Efficacy of accommodating variable-resistance training on muscle architecture, peak torque, and functional performance in patients with juvenile idiopathic arthritis: A randomized controlled trial

Purpose

This study sought to find out if a 6-week accommodating variable-resistance (AcVR) training might enhance muscle architecture, peak torque, and functional performance in patients with juvenile idiopathic arthritis (Juv-IA).

Methods

Fifty-eight patients with polyarticular Juv-IA (aged 12-18 years) were involved in a randomized controlled trial. They were allocated into two groups: the AcVR group (n = 29; underwent AcVR training, and the control group (n = 29; received the usual exercise regimen). Interventions were applied three times a week over six consecutive weeks. Measurements were done at baseline and after the intervention. The primary outcome measures were muscle architecture and peak torque, with functional capacity being the secondary measure.

Results

Compared to the control group, the AcVR group showed favorable pre-to-post changes in muscle architecture [fascicle length (P = 0.0007, η2p = .18), pennation angle (P = 0.0004, η2p = .20), and muscle thickness (P = 0.001, η2p = .17)]. Further, the AcVR group revealed a greater increase in peak concentric torque of knee extensors at angular speeds of 120°/sec [right side (P = 0.0032, η2p = .08); left side (P = 0.039, η2p = .07)] and 180°/sec [right side (P = 0.01, η2p = .11); left side (P = 0.014, η2p = .10)]. Furthermore, The AcVR group achieved more conducive changes in functional performance [6-min walk test (P = 0.003, η2p = .15), timed up and down stair test (P = 0.009, η2p = .12), and 4 × 10 m shuttle run test (P = 0.036, η2p = .08)].

Conclusion

A 6-week AcVR training is potentially effective for improving muscle architectural qualities, enhancing peak muscle torque, and boosting functional performance in patients with Juv-IA without experiencing any detrimental side effects.

Effects of Plyometric-Based Hydro-Kinesiotherapy on Pain, Muscle Strength, Postural Stability, and Functional Performance in Children with Hemophilic Knee Arthropathy: A Randomized Trial

AIM

To explore how plyometric-based hydro-kinesiotherapy (Plyo-HKT) would affect pain, muscle strength, postural stability, and functional performance in a convenience sample of children with hemophilic knee arthropathy (HKA).

METHODS

Forty-eight children with HKA (age: 8-16 years) were randomly allocated to the Plyo-HKT group (n = 24; underwent the Plyo-HKT for 45 min, twice/week over 12 wk in succession) or the comparison group (n = 24; performed the standard exercise rehabilitation at an equivalent frequency and duration). Pain, peak concentric torque of quadriceps and hamstring (produced at two angular velocities: 120 and 180 o/sec), dynamic limits of postural stability (DLPS), and functional performance [Functional Independence Score in Hemophilia (FISH) and 6-Minute Walk Test (6-MWT)] were assessed pre- and post-intervention.

RESULTS

In contrast with the comparison group, the Plyo-HKT group achieved more favorable pre-to-post changes in pain (p = .028, η2p = 0.10), peak torque of quadriceps [120°/sec (p = .007, η2P = 0.15); 180°/sec (p = .011, η2P = 0.13)] and hamstring [120°/sec (p = .024, η2P = 0.11); 180°/sec (p = .036, η2P = 0.09)], DLPSdirectional [forward (p = .007, η2P = 0.15); backward (p = .013, η2P = 0.12); affected side (p = .008, η2P = 0.14); non-affected side (p = .002, η2P = 0.20)], DLPSoverall (p < .001, η2P = 0.32), and functional performance [FISH (p < .001, η2p = 0.26); 6-MWT (p = .002, η2p = 0.19)].

CONCLUSION

Plyo-HKT is likely helpful for reducing pain, improving strength, enhancing postural stability, and boosting functional capabilities in children with HKA. Physical rehabilitation practitioners should, therefore, consider this intervention strategy.

Effect of melatonin on reproductive function in propylthiouracil induced hypothyroidism in adult male rats

OBJECTIVE

Thyroid hormones are essential for regulating metabolism, reproduction, and growth. Hypothyroidism is connected with lower sperm count and motility, leading to male infertility. Oxidative stress is likely to be linked to this interaction. Melatonin, being known as an oxidative scavenger, may offer a feasible treatment method for reproductive dysfunction accompanying hypothyroidism in adult male rats. The purpose of this investigation was to determine the mechanism by which melatonin treatment affected spermatogenic and steroidogenic function in an experimental model-induced hypothyroidism in adult male rats.

MATERIALS AND METHODS

Twenty-one male albino adult rats weighing between 150 and 210 g were used in this experiment. Rats were split into three groups and studied for 11 weeks. The control euthyroid group, in which rats received 0.9% Sodium Chloride (NaCl) solution by intraperitoneal injection [solvent for 6-propyl 2-thouracil (PTU)], 6 days/week for 8 weeks; the PTU-induced hypothyroid group, in which chemical thyroidectomy was induced by intraperitoneal injection of PTU at a dose of 10 mg/kg body weight, 6 days/week for 8 weeks; and the melatonin-treated hypothyroid group, which received 3 mg/kg melatonin intraperitoneally daily for 21 days plasma free Triiodothyronine (T3), free Thyroxin (T4), thyroid stimulating hormone (TSH), free testosterone, Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH) and prolactin were measured. Also, semen analysis, testicular tissue malondialdehyde (MDA), and tumor necrosis factor-α (TNF-α) were accessed.

RESULTS

The results indicated that melatonin significantly increased sperm viability and motility compared to the untreated PTU-induced hypothyroid group (p<0.001). Testicular MDA and TNF-α showed a significant decrease in the melatonin-treated hypothyroid group compared with the PTU-induced hypothyroid group (p<0.05). In addition, plasma testosterone levels were significantly increased, accompanied by a significant reduction of plasma prolactin levels compared to the untreated hypothyroid group (p<0.05 for both).

CONCLUSIONS

Based on the study findings, melatonin could mitigate gonadal dysfunction induced by hypothyroidism by improving several components of semen analysis, such as sperm motility and sperm viability, as well as by enhancing testosterone production focusing on oxidative and inflammatory stress as the underlying mechanisms.

Optimization of Postural Control, Balance, and Mobility in Children with Cerebral Palsy: A Randomized Comparative Analysis of Independent and Integrated Effects of Pilates and Plyometrics

The paradigm of comprehensive treatment approaches for children with cerebral palsy has gained traction, prompting clinicians to deliberate between independent and integrated treatment delivery. However, this decision-making process is often hindered by the dearth of empirical evidence available to inform optimal therapeutic strategies. This study, therefore, sought to compare the effects of Pilates-based core strengthening (PsCS), plyometric-based muscle loading (PlyoML), and their combination on postural control, balance, and mobility in children with unilateral cerebral palsy (ULCP). Eighty-one children with ULCP (age: 12-18 years) were randomized to PsCS (n = 27), PlyoML (n = 27), or a combined intervention (n = 27; equated for total sets/repetitions) group. The three interventions were applied twice/week over 12 successive weeks. Postural control (directional and overall limits of stability-LoS), balance, and mobility (Community Balance and Mobility Scale-CB&M; Functional Walking Test-FWT; Timed Up and Down Stair test-TUDS) were assessed pre- and post-intervention. The combined group exhibited greater increases in directional LoS compared to PsCS and PlyoML including the backward (p = 0.006 and 0.033, respectively), forward (p = 0.015 and 0.036, respectively), paretic (p = 0.017 and 0.018, respectively), and non-paretic directions (p = 0.006 and 0.004, respectively)], and this was also the case for overall LoS (p < 0.001 versus PsCS and PlyoML). In addition, the combined group displayed greater improvements compared to the PsCS and PlyoML groups regarding CB&M (p = 0.037 and p = 0.002, respectively), FWT (p = 0.012 and p = 0.038, respectively), and TUDS (p = 0.046 and p = 0.021, respectively). In conclusion, the combined PsCS and PlyoML exercise program promotes considerably greater improvements in postural control, balance, and mobility compared to unimodal training in children with ULCP.

Virtual reality-based exercises' effects on pulmonary functions, cardiopulmonary capacity, functional performance, and quality of life in children with repaired congenital diaphragmatic hernia

OBJECTIVE

The long-term consequences of congenital diaphragmatic hernia (CDH), which include altered lung functions and compromised cardiopulmonary capacity, impact functional performance and quality of life. This study investigates the effects of virtual reality-based exercise programs on pulmonary functions, cardiopulmonary capacity, functional performance, and quality of life in children with repaired CDH.

PATIENTS AND METHODS

A randomized controlled clinical trial was performed. Fifty-two children with repaired CDH (aged 6-10 years) were enrolled and randomly allocated to virtual reality-based exercises plus traditional physical therapy (VR-EX group, n = 26) or traditional physical therapy alone (control group, n = 26). Interventions were conducted three times a week for 12 weeks. Pulmonary functions, cardiopulmonary capacity, functional performance, and quality of life were assessed before and after the intervention.

RESULTS

The VR-EX group demonstrated significantly enhanced post-treatment pulmonary functions and cardiopulmonary capacity compared to the control group after accounting for the pre-treatment values (p < 0.05). In addition, the values in functional performance and quality of life measures showed significantly larger improvements in the VR-EX group (p < 0.05).

CONCLUSIONS

Children with repaired CDH may benefit more from VR-based exercises when combined with traditional physical therapy than from traditional physical therapy alone regarding their pulmonary functions, cardiopulmonary capacity, functional performance, and quality of life.

Parental knowledge of children's motor development: A cross-sectional study in Saudi Arabia

BACKGROUND

This study was undertaken to explore parental knowledge of normal motor development. In addition, the association between parental knowledge and characteristics was investigated.

METHODS

A cross-sectional design was adopted for this study. An online survey was used to administer a four-part questionnaire designed for this study. The first part of the questionnaire focused on demographic information, such as age, age at birth of first child, and educational level. The second part consisted of questions about birth-related information sources, and the third part included questions about normal motor development. The fourth part was directed to participants who had children with DDs. The data were analysed descriptively and reported using absolute and relative frequencies. Linear regression was used to investigate the association between parental knowledge level and gender, age, education, age at first birth, number of children, and self-rated knowledge level.

RESULTS

A total of 4081 participants responded to the survey. Most participants were found to have low levels of parental knowledge, as 88.87% answered ≤ 50% of the developmental milestone questions correctly. Being a female and having a university education were significantly associated with high knowledge levels (p < 0.001 for both variables). Further, undergoing an awareness programme about normal child development was significantly associated with high knowledge levels (p = 0.02). No association was found between the factors of age, age at first birth, number of children, and knowledge rating and the level of parental knowledge about normal physical development.

CONCLUSION(S)

There is a lack of appropriate knowledge about normal motor development among parents in Saudi Arabia, which raises serious concerns about children's health in the country.

IMPLICATIONS

Effective health education programmes on normal developmental milestones should be implemented by the Ministry of Health to improve the developmental outcomes of children in Saudi Arabia.

Combined effect of graded Thera-Band and scapular stabilization exercises on shoulder adhesive capsulitis post-mastectomy

PURPOSE

The main aim of the trial was to assess the combined impact of graded Thera-Band strengthening exercises and scapular stabilization exercises on shoulder pain, physical function, and quality of life (QoL) in post-mastectomy adhesive capsulitis (AC).

METHODS

Seventy females with unilateral post-mastectomy AC partook in the trial. Participants were subdivided equally into two groups at random. Both groups obtained the traditional physical therapy program; in addition, the intervention group received graded Thera-Band exercises for shoulder muscles and scapular stabilization exercises 5 days a week for 8 weeks. Range of motion (ROM) and muscle power of shoulder were assessed by digital goniometer and handheld dynamometer, respectively. Disability of the Arm, Shoulder, and Hand questionnaire (DASH) was utilized for assessment of shoulder function and visual analogue scale (VAS) for pain measurement while short-form (SF-36) for QoL assessment. All evaluation data was recorded prior to the trial and at the eighth week of interventions for both groups.

RESULTS

All participants achieved improvements in shoulder ROM, muscle power, pain, and all aspects of QoL; however, higher statistical improvements were reported in all measurements with respect to strengthening exercises group (p < 0.001).

CONCLUSION

The addition of graded Thera-Band strengthening exercises and scapular stabilization exercises in post-mastectomy AC rehabilitation program has significant benefits in shoulder function and patients' QoL.

Effects of intermittent aerobic training on exercise capacity, pulmonary functions, and gait parameters in asthmatic children with cerebral palsy: a randomized controlled trial

OBJECTIVE

There is no evidence that exercise training program is effective in improving aerobic capacity, musculoskeletal abnormalities, and quality of life in asthmatic children with cerebral palsy (CP). Therefore, the effects of intermittent aerobic training on exercise capacity, pulmonary function, and gait parameters in asthmatic CP children have been evaluated in the current study.

PATIENTS AND METHODS

This clinical trial included thirty-six asthmatic CP children between January and December 2021. Their ages were between 7 and 12 years old. They were randomly allocated to the intermittent aerobic exercise group (IAEG) and a control group (CG), with 18 per each group. The children have been recruited for the 10-week interventional program. The 6-minute walk test (6MWT), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), stride length, cadence, gait speed, and pediatric asthma quality of life (PAQLQ) were all measured before and after treatment.

RESULTS

Pre-post analysis in the IAEG showed noteworthy changes (6MWT, p=0.005; FVC, p=0.002; FEV1, p<0.001; overall score of PAQLQ, p<0.001; stride length, p<0.001; cadence, p<0.001; and gait speed, p˂0.001), while the control group showed non-significant changes (p>0.05). There were noteworthy differences between IAEG and CG post-treatment (6MWT, p=0.019; FVC, p=0.031; FEV1, p<0.001; overall score of PAQLQ, p=0.031; stride length, p<0.001; cadence, p=0.009; and gait speed, p<0.001) in favor of the IAEG.

CONCLUSIONS

Depending on the study findings, 10 weeks of intermittent aerobic exercise may improve exercise capacity, pulmonary function, gait parameters, and quality of life in asthmatic CP children. Based on what we found, this protocol should be used in pulmonary rehabilitation programs for children with CP who have breathing problems.

Impact of Clinical Pilates Exercise on Pain, Cardiorespiratory Fitness, Functional Ability, and Quality of Life in Children with Polyarticular Juvenile Idiopathic Arthritis

Objective: This study intended to examine the effects of Pilates exercise on pain, cardiorespiratory fitness, functional ability, and quality of life in children with polyarticular juvenile idiopathic arthritis. Methods: Forty children with polyarticular JIA aged 10−14 years old were randomly allocated into two groups: the control group (n = 20) received conventional physical therapy (CPT), and the experimental group (n = 20) received clinical Pilates exercises combined with CPT. Patients in both groups received their program three times/week for 3 months. Pain, cardiorespiratory fitness, functional ability, and quality of life were assessed through the visual analogue scale, cardiopulmonary exercise test, 6 min walk test, and PedsQL scale, respectively, just before and after treatment. Results: Pain (p = 0.001), cardiorespiratory markers (all p < 0.05), functional ability (p = 0.002), and overall quality of life (p = 0.007) improved significantly in the experimental groups compared to the control group. Conclusion: Incorporating Pilates exercises into CPT is likely more effective for decreasing pain intensity, improving cardiorespiratory fitness, augmenting functional ability, and promoting quality of life in children with JIA than CPT alone.

Effect of Chest Resistance and Expansion Exercises on Respiratory Muscle Strength, Lung Function, and Thoracic Excursion in Children with a Post-Operative Congenital Diaphragmatic Hernia

BACKGROUND

Congenital diaphragmatic hernia (CDH) is a life-threatening condition with long-term complications including respiratory tract infections, respiratory muscle weakness, and abnormal lung functions. This study was designed to ascertain the effects of chest resistance and chest expansion exercises on respiratory muscle strength, lung function, and chest mobility in children with post-operative CDH.

METHODS

This randomized controlled clinical study was conducted in the outpatient physiotherapy clinic at Prince Sattam bin Abdulaziz University. Thirty-two children with CDH aged 10-14 years between May 2020 and February 2021 were randomly allocated to the study group (n = 16) and the control group (n = 16). The control group underwent a usual chest physiotherapy program; however, the study group underwent a 12-week chest resistance exercise combined with chest expansion exercise in addition to usual chest physiotherapy, with three sessions per week. Respiratory muscle strength, lung function, and thoracic excursion were assessed pre- and post-treatment.

RESULTS

Using the 2 × 2 repeated ANOVA, significant time × group interactions were detected in favor of the study group, FVC (F = 4.82, 95% CI = -15.6 to -0.97, p = 0.005, and η² = 0.16), FEV1 (F = 4.54, 95% CI = -11.99 to -2.8, p ˂ 0.001, and η² = 0.14), PImax (F = 5.12, 95% CI = -15.71 to -5.3, p ˂ 0.001, and η² = 0.15), and thoracic excursion (F = 4.41, 95% CI = -2.04 to -0.16, p = 0.036, and η² = 0.17).

CONCLUSIONS

Concurrent chest resistance and expansion exercises may improve respiratory muscle strength, lung function, and thoracic excursion in children with post-operative CDH. The study findings suggest that concurrent chest and chest expansion exercises be part of an appropriate pulmonary rehabilitation program in children with a history of CDH.

The effect of McKenzie protocol vs. deep neck flexor and scapulothoracic exercises in subjects with chronic neck pain - a randomized controlled study

OBJECTIVE

This study investigated the impact of McKenzie exercises against deep neck flexor (DNF) combined with scapulothoracic exercises on improving pain severity, cervical mobility, and functional disability.

PATIENTS AND METHODS

Fifty-five subjects suffering from chronic neck pain participated in this randomized controlled study. They were randomly assigned to three groups; the DNF group, which was treated by traditional physical therapy (i.e., physical therapy agents, stretching, and isometric exercises), combined with DNF, and scapulothoracic exercises; the McKenzie group, treated by traditional physical therapy, combined with McKenzie exercises; and finally, a control group, treated by traditional physical therapy. Before and after 6 weeks of treatment, they were assessed for neck pain severity, cervical range of motion (ROM), and functional disability using a visual analog scale (VAS), a gravity-reference goniometer, and the Copenhagen neck functional disability scale (CNFDS), respectively.

RESULTS

Compared to baseline, all groups showed a significant decrease in neck pain severity and disability (p <0.05), and there was a significant increase in neck flexion/extension, lateral right flexion/left flexion, and right/left rotation ROMs (p<0.05). The improvement of the McKenzie group was significantly higher than the DNF group, and control group. Moreover, the improvement of the DNF group was significantly higher than the control group (p<0.05).

CONCLUSIONS

The McKenzie exercises were better than DNF combined with scapulothoracic exercises to treat neck pain, functional disability, and mobility.

Block-sequence of plyometric and balance training is superior to the alternating-sequence for enhancing motor function in children with hemiplegic cerebral palsy: A comparative randomized clinical trial

BACKGROUND: Postural control deficits are prevalent in children with hemiplegic cerebral palsy (CwHCP). Therefore, the best rehabilitative strategies for remediating these deficits are warranted, which could then enhance function. OBJECTIVE: To examine effects of a block versus an alternating sequence of balance training (BT) and plyometric training (PT) on postural control in CwHCP. METHODS: Forty-eight CwHCP (812 years) were randomized to a block or an alternating BT/PT training. The block BT/PT group (n= 24) received a sixweek BT followed by a sixweek PT, twice/week over 12 consecutive weeks. The alternating BT/PT group (n= 24) received an interchanging sequence of BT and PT changed every two weeks for 12 weeks. Postural control [center-of-pressure reaction time (RT), movement velocity (MV), maximum excursion (ME), end-point excursion (EE), and directional control (DC)], functional balance (indicated by pediatric balance scale; PBS), and balance/risk-of-falls during walking (denoted by dynamic gait index; DGI) were assessed before and after training. RESULTS: The block BT/PT group showed greater enhancements in postural control variables [RT (P= 0.004), MV (P= 0.028), ME (P= 0.002), EE (P= 0.003), and DC (P= 0.012)] and functional balance (P= 0.006), and lesser risk-of-falls during walking (P= 0.018) when compared to the alternating BT/PT group. CONCLUSION: The block BT/PT sequence is more effective to enhance postural control than the alternating sequence in CwHCP.

Distinct effects of trampoline-based stretch-shortening cycle exercises on muscle strength and postural control in children with Down syndrome: a randomized controlled study

OBJECTIVE

The aim of the study was to investigate the effect of a 3-month, trampoline-based stretch-shortening cycle (SSC) exercises on muscle strength and postural control in children with Down's syndrome (DS).

PATIENTS AND METHODS

Thirty-two children with DS aged between 7-9 years were enrolled and randomly assigned into the control group (n = 16); received standard physical therapy (sPT) or SSC group (n = 16); received sPT in addition to a 15-minute, trampoline-based SSC training program twice per week for 12 successive weeks. Lower limb muscle strength and postural stability [anterior/posterior stability index (A/P-SI), medial/lateral stability index (M/L-SI)], and overall stability index (O-SI) were assessed pre- and post-treatment.

RESULTS

Strength of hip extensor (p=0.034) and adductor (p=0.015), knee extensor (p=0.028) and flexor (p=0.01), and ankle dorsi (p=0.033) and plantar flexor (p=0.007) muscles increased significantly in the SSC group when compared with the control group. Also, the A/P-SI (p=0.019), M/L-SI (p=0.002), and O-SI (p=0.021) decreased significantly in the SSC group when compared with the control group, suggesting better postural control.

CONCLUSIONS

Twelve weeks of trampoline-based SSC exercises are likely effective for enhancing muscle strength and postural control in children with DS and should consequently be included in the rehabilitation programs for these children.

Incorporation of Pilates-based core strengthening exercises into the rehabilitation protocol for adolescents with patellofemoral pain syndrome: a randomized clinical trial

OBJECTIVE

The objective of this study was to evaluate how a Pilates-based core strengthening exercise program affected pain, lower limb muscle strength, functional status, and health-related quality of life in adolescents with patellofemoral pain syndrome (PFPS).

MATERIALS AND METHODS

In this randomized controlled clinical trial, 34 teenagers with PFPS (ages 14-17) were randomly assigned to receive either a standard PT program (control group) or Pilates exercises plus the conventional program (study group). Both groups continued the treatment sessions for 3 months (3 sessions/week). Pain intensity, lower limb muscle strength (hip abductors and external rotators and knee extensors), functional status, and health-related quality of life were evaluated pre-and post-intervention.

RESULTS

Pain intensity (p =.005) reduced significantly post-treatment in the study group as compared to the control group, when controlled for the pre-treatment value. Also, muscle strength of hip abductors (p =.002) external rotators (p < .001), knee extensors (p = .013), functional status (p = .002), and health-related quality of life (p < .001) increased significantly in the study group when compared to the control group.

CONCLUSIONS

The results of this study show that Pilates-based core strengthening exercises can help adolescents with PFPS reduce pain, enhance muscle strength, and improve their functional status and quality of life.

Optimization of pulmonary function, functional capacity, and quality of life in adolescents with thoracic burns after a 2-month arm cycling exercise programme: A randomized controlled study

BACKGROUND

Burns to the thorax are at high risk for long-term pulmonary complications due to chest muscle contractures and chronic inflammation in both adolescents and young adults. Few studies have investigated the effects of arm cycling exercise in those individuals. For that reason, this study examined pulmonary function, functional capacity, and quality of life (QOL) in adolescents with thoracic burns subsequent to 2-month arm cycling exercise programme.

METHODS

A single-blinded, two-month randomized prospective controlled study was carried out between July 2019 and March 2020 on thirty adolescents with chest burns aged 11-17 years. They were randomized into two equal groups (n = 15), traditional physiotherapy programme (control group), and arm cycling exercise plus traditonal physiotherapy (arm cycling exercise group) for 2 consecutive months. Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), six-minute walk test (6MWT), and Pediatric Quality of Life Inventory (PedsQL) were measured in both groups at baseline and after 2-month after intervention.

RESULTS

No statistical significance was detected at baseline between control and arm cycling exercise groups (FVC, p = 0.903, FEV1, p = 0.835, 6MWT, p = 0.817, and PedsQL, p = 0.612). 2 months after intervention showed statistical improvements in the arm cycling exercise group in all measures (FVC, p = 0.001, FEV1, p < 0.0001, 6MWT, p = 0.001, and PedsQL, p = 0.001) however, the control group showed statistical improvements in FVC, p = 0.044 and FEV1, p = 0.024 with non-statistically significant changes in 6MWT, p = 0.145 and PedsQL, p = 0.067. The arm cycling exercise group showed greater improvements than control group in the outcome measures (FVC, p = 0.034, FEV1, p < 0.017, 6MWT, p = 0.037, and PedsQL, p = 0.021).

CONCLUSIONS

This prospective study clearly demonstrated positive and beneficial influences of two-month arm cycling exercise in the optimization of pulmonary functions, functional performance, and QOL in adolescents suffering from chest burns and thereby eliminating post-burn complications.

Beyond the acute phase: understanding relationships among cardio-respiratory response to exercises, physical activity levels, and quality of life in children after burn injuries

The long-term cardiorespiratory function in burn-injured children can be jeopardized due to complications brought on by the injury. This study sought to assess the cardio-respiratory responses to maximal exercise in children who sustained a burn injury and explore the relationships among cardio-respiratory response, physical activity levels (PALs), and health-related quality of life (HRQL). Forty-five burn-injured children (age:13.89±2.43 years; duration since burn-injury: 3.13±0.93 years) and 52 age- and gender-matched healthy children (14.15±2.27 years) participated in this study. Both cohorts were evaluated for the maximal exercise capacity [defined by peak oxygen uptake (VO2peak), maximum heart rate (HRmax), minute ventilation (VE), ventilatory equivalent (VEq), respiratory rate (RR), and respiratory exchange ratio (RER)], PALs, and HRQL. The burn-injured children had significantly lower VO2peak (P=.0001) and VE (P=.003) and higher VEq (P<.0001) and RR (P=.007) than their healthy controls, indicating less efficient cardio-respiratory capacity. However, the HRmax (P=.092) and RER (P=.251) were similar. The burn-injured children reported significantly lower PALs (P=.014) and HRQL (P<.0001). The PALs [r (95%CI) = 0.411 (0.132 to 0.624); P = .005] and HRQL [r (95%CI) = 0.536 (0.284 to 0.712); P = .0001] were significantly correlated with the cardio-respiratory capacity represented by VO2peak in burn-injured group. The variations in VO2peak explained ⁓ 17% and 28.7% of the variations in PALs and HRQL, respectively. In conclusion, the cardio-respiratory efficiency of the burn-injured children may remain limited, even up to a few years following the injury. The limited cardio-respiratory capacity account in part for the reduced PALs and HRQL.

Potential impacts of Acu-TENS in the treatment of adolescents with moderate to severe bronchial asthma: A randomized clinical study

OBJECTIVE

The purpose of this study was to evaluate the efficacy of transcutaneous electrical nerve stimulation over the acupuncture points (Acu-TENS) on total serum immunoglobulin E (IgE_total), pulmonary function, and quality of life in adolescents with asthma.

METHODS

In a double-blind randomized clinical trial, 32 adolescents (age; 12-16 years) with asthma participated and were assigned randomly to receive either the breathing retraining program (control group) or the breathing retraining program plus Acu-TENS application (Acu-TENS group). Acu-TENS was applied for 40 min' day-after-day session for two successive months, with no side-effects reported. Serum IgE_total, pulmonary function [forced vital capacity (FVC), forced expiratory volume at one second (FEV₁), and FEV₁/FVC], and quality of life were evaluated pre- and post-treatment.

RESULTS

Serum IgE_total (P = 0.028, η_p² = 0.15), Pulmonary function [FVC (P = 0.043, η_p² = 0.13), FEV₁ (P = .046, η_p² = 0.12)], and quality of life (P < .001, η_p² = 0.17) increased significantly in the Acu-TENS group when compared to the control group.

CONCLUSION

This study demonstrates that the Acu-TENS is an impending asthma treatment that may be used to reinforce the immune system response, ameliorate lung function, and increase the quality of life in adolescents with asthma.

Therapeutic value of kinesio taping in reducing lower back pain and improving back muscle endurance in adolescents with hemophilia

OBJECTIVE

This study evaluated whether the use of kinesio taping (KT) would enhance the effect of physical therapy in relieving pain, improving muscle endurance, and boosting functional capacity in adolescents with hemophilia who experience low back pain.

METHODS

Forty-five adolescents with hemophilia (age; 10-13 years) assigned randomly into three treatment arms; KT applied paraspinal alongside a physical exercise program conducted three times/week for three successive months (KT group; n=15), placebo taping plus physical exercise (Placebo group; n=15), or physical exercise only (Control group; n=15). Lower back pain, back muscle endurance, and functional capacity assessed pre- and post-treatment.

RESULTS

Lower back pain reduced significantly in the KT group as compared to the control group (P=.001), but not to the placebo group (P=.19). Back muscle endurance increased significantly in the KT group relative to either the placebo (P=.004) or the control group (P=.043). Additionally, functional capacity improved significantly in the KT group as compared to the control (P=.039) group but not to the placebo group (P=.58).

CONCLUSION

KT is an effective adjunctive therapy to reduce lower back pain, improve back muscle endurance, and enhance functional capacity in adolescents with hemophilia.
