Poor lumbar spine coordination in acute low back pain predicts persistent long-term pain and disability.

PURPOSE: Sitting balance on an unstable surface requires coordinated out-of-phase lumbar spine and provides sufficient challenge to expose quality of spine control. We investigated whether the quality of spine coordination to maintain balance in acute low back pain (LBP) predicts recovery at 6 months. METHODS: Participants in an acute LBP episode (n = 94) underwent assessment of sitting balance on an unstable surface. Seat, hip and spine (lower lumbar, lumbar, upper lumbar, thoracic) angular motion and force plate data were recorded. Coordination between the seat and hip/spine segments to maintain balance was quantified in the frequency domain to evaluate coordination (coherence) and relative timing (phase angle: in-phase [segments move together]; out-of-phase [segments move opposite]). Center of pressure (CoP) and upper thorax motion assessed overall balance performance. Hip and spine coordination with the seat were compared between those who did not recover (increased/unchanged pain/disability), partially recovered (reduced pain/disability) or recovered (no pain and disability) at 6 months. RESULTS: In both planes, coherence between the seat and lower lumbar spine was lower (and in-phase-unhelpful for balance) at baseline in those who did not recover than those who recovered. Coherence between the seat and hip was higher in partially recovered in both planes, suggesting compensation by the hip. LBP groups had equal overall balance performance (CoP, upper thorax motion), but non-recovery groups used a less optimal strategy that might have consequences for long-term spine health. CONCLUSION: These longitudinal data revealed that individuals with compromised contribution of the lumbar spine to the balance during unstable sitting during acute LBP are less likely to recover.

Coordination of hip and spine to maintain equilibrium in unstable sitting revealed by spectral analysis.

Unstable sitting paradigms have been used to assess the trunk's contribution to postural control. The coordination of spine or hip with an unstable seat that underpin postural control during this task remain unclear. This study aimed to address this issue using analysis in the frequency domain. Seventy-two healthy pain-free participants maintained balance while sitting on a seat fixed to a hemisphere. Angular motion of seat, spinal regions (lower lumber, lumbar, upper lumbar, and thoracic), and hip was recorded with a three-dimensional (3-D) motion capture system. Coordination between spinal regions and hip with the seat was quantified using cross-spectral analyses. In the sagittal plane, amplitude spectrum of hip and lumbar segments were higher than other segments, coherence between these segments and the seat was high, and their motion was generally opposite in direction to the seat. In the frontal plane, amplitude spectrum of lower lumbar and lumbar segments, but not the hip, were higher than other segments, and coherently moved in the opposite direction to the seat. Segments closest to the seat made a direction-specific and greater contribution to maintenance of equilibrium than upper body segments, which were more limited during unstable sitting. Although eye closure and higher body mass index involved larger amplitude of center of pressure movement, rather than inferring poor control, this was associated with enhanced coordination between segments and seat. Understanding how hip/spine segments are coordinated with the seat is important to interpret postural strategies used to maintain equilibrium and to interpret observations for other populations (e.g., back pain).NEW & NOTEWORTHY This is the first multidirectional spectral analysis of how the hip and spine coordinate during unstable sitting and how different factors impact this coordination. Seat movement was coherently counteracted (out-of-phase) by angular motion of the hip and lower lumbar spine in the sagittal plane and by the lumbar spine in the frontal plane. Although higher BMI and balancing with eyes closed increased movement amplitude, this did not compromise coordination between segments to control balance, instead, coherence increased.

Inter-rater reliability of physiotherapists using the Action Research Arm Test in chronic stroke.

OBJECTIVES: The purpose of this study is to establish whether physiotherapists' ratings are consistent, when using the Action Research Arm Test (ARAT) to score a chronic stroke patient. METHODS: This was part of a large project establishing the reliability in chronic stroke. This study used a correlational design comparing the association between physiotherapist scores of the same patient, to establish the ARAT's inter-rater reliability. The COSMIN checklist was followed to enhance the methodology of the study. RESULTS: Twenty physiotherapists (8 female and 12 male) aged between 25 and 53 years were selected. There were no participant dropouts or withdrawals. The sample size was normally distributed. The physiotherapists appeared representative of the UK physiotherapy population, with the exception of gender. The distribution of scores showed a normal distribution with standard deviation of score of 1.9. The Kendall's W test showed 0.711 of agreement between the raters. The scores achieved statistical significance showing consistency between physiotherapists' scores with chronic stroke. Limitations of the study were the use of a small single center convenience sample that may reduce the generalizability of the findings. CONCLUSIONS: The ARAT is consistent when scored by physiotherapists in a chronic stroke population. The inter-rater reliability range was (0.70 to 0.90) which is categorized as good.

The effectiveness of McKenzie method compared to manual therapy for treating chronic low back pain: a systematic review.

The aim of this study was to evaluate the effectiveness of the McKenzie method compared to manual therapy in the management of patients with chronic low back pain (CLBP). Randomised controlled trials evaluating the McKenzie method in treating CLBP in adults compared to manual therapy (MT) were searched in MEDLINE, CINAHL, Cochrane Library, and PEDro. The primary outcomes were pain and disability. Five trials were eligible for inclusion in the review, of which, most had a score of 8 out of 11 on the PEDro scale. At 2-3 months, all studies reported significant improvement in the pain level in the McKenzie group, and more than that in the MT group. At 6 months, significant improvements had occurred in the disability index reported by two trials in the McKenzie group than the MT group. At 12 months follow-up, there were no significant differences in measures of LBP, but three studies reported that the McKenzie method group had a better disability level than the MT group. In patients with CLBP, many pain measures showed that the McKenzie method is a successful treatment to decrease pain in the short term, while the disability measures determined that the McKenzie method is better in enhancing function in the long term.

A meta-analysis of meta-analyses of the effectiveness of FIFA injury prevention programs in soccer.

FIFA has a Medical and Research Centre (F-MARC) which has designed a comprehensive program targeting muscle strength, kinesthetic awareness, and neuromuscular control during static and dynamic movements to decrease injury risk for soccer players. A number of meta-analyses now exist on how effective FIFA's programs to prevent and reduce injury actually are, with various degrees of injury reduction reported. This research aimed to carry out a systematic review and to meta-analyse the existing meta-analyses so that a conclusion can be drawn on how effective the injury programs are. Relevant studies were identified by searching five databases for the period January 1990 till 1 July 2018. Results of each meta-analysis were combined together using risk ratios (RR) in a summary meta-analysis. QUOROM checklist and AMSTAR 2 assessment were used to assess the quality of reporting and methodology in the meta-analyses. Four meta-analyses met the inclusion criteria covering fifteen primary studies. All four meta-analyses scored quite highly on QUOROM, but two were rated by AMSTAR 2 as moderate quality, and two were found to be of critically low quality. An overall risk reduction in 34% (RR = 0.66 [0.60-0.73]) for all injuries and a reduction in 29% (RR = 0.71 [0.63-0.81]) for injuries to the lower limbs were revealed by this meta-analysis of meta-analyses. Combining every previous meta-analysis into a single source in this paper produced decisive evidence that the risk of injuries while playing soccer is reduced as a result of FIFA's injury prevention programs.

Can the stroke impact scale 3.0 detect cognitive impairments in patients with a recent stroke?

[Purpose] The aim of this study was to identify cognitive impairments in patients with a recent stroke using Stroke Impact Scale 3.0 (SIS). [Participants and Methods] A retrospective cohort study was conducted to evaluate 50 medical records in patients with a recent stroke who have completed a stroke rehabilitation programme. All data were evaluated at St. Finbarr's Hospital in Cork, Ireland. [Results] A total of 41 records met the inclusion criteria, of which 53.7% were male. Regarding the risk factors, most patients complained of hypertension (85.4%), with most being diagnosed with embolic stroke (56.1%). The SIS identified numerous issues in stroke patients, such as persistent problems with memory (36.6%), concentration (29.3%), and solving everyday problems (43.9%). In addition, some patients' responses were negative regarding their emotion such as feeling sad (51.2%), not enjoying things as much as ever (39%), feeling life is not worth living (85.4%) and not smiling or laughing at least once a day (80.5%). [Conclusion] The inclusion of the SIS in the stroke review clinic identified cognitive deficits that may not have otherwise been detected. By using SIS in a systematic and standardised way, deficits can be identified, and appropriate rehabilitation can be provided.

Test-retest reliability of physiotherapists using the action research arm test in chronic stroke.

[Purpose] The aim of this study was to determine whether physiotherapists (PT) scores are consistent over time when using Action Research Arm Test (ARAT) to assess upper limb (UL) function on a videotaped chronic stroke patient. [Participants and Methods] Quantitative correlational study. A convenience-snowball sample of 20 international PT (mean age and experience=32 ± 6.8 and 7.55 ± 7.4 years) used ARAT to score chronic stroke patient's UL function, observing a video at baseline and again ≈ 2 weeks later. Two sets of non-parametric ordinal data were assessed with Spearman's (rho) and the alpha (a) value was set at 0.01. Line of equality, Bland-Altman plots and Wilcoxon signed rank test were also considered. [Results] Spearman's rho was found ≈ 0.78 at a significance level of 0.00. ARAT was scored with a mean difference of 16.6 days and a mean change of 0.6 points was observed. Limits of agreement and coefficient of reproducibility were ± 2.3 and ± 2.6 respectively. The patient's arm impairment was categorised as moderate and floor or ceiling effects were not detected. [Conclusion] The results suggest that ARAT is consistent, valid and should be used by PT in chronic stroke.

The effectiveness of manual therapy in treating cervicogenic dizziness: a systematic review.

[Purpose] This review provides an evaluation of the evidence for the effectiveness of using manual therapy to treat cervicogenic dizziness. [Subjects and Methods] The literature was systematically searched on the May 2, 2016 using the following online databases: Medline, EMBASE, CINAHL and PEDro. This review included randomised controlled trials and compared the efficacy of manual therapy for the treatment of cervicogenic dizziness, compared to other types of intervention. This study measured changes based on dizziness intensity and frequency. [Results] The primary search found 30 articles, but only four articles met the inclusion criteria. Assessment of methodological quality was performed by two researchers using the PEDro scale. The level of evidence was determined using a recognised grading scale. Three out of the four articles were deemed to have high methodological quality, while the fourth was rated as moderate quality. The attributed level of evidence was moderate (level 2). [Conclusion] Manual therapy is potentially effective for managing cervicogenic dizziness. However, due to the heterogeneity of the results and techniques and the low number of studies, further research is recommended to provide conclusive evidence.

The feasibility of using exergames as a rehabilitation tool: the attitudes, awareness, opinions and experiences of physiotherapists, and older people towards exergames.

[Purpose] The aim of this study was to investigate the feasibility of using exergames as a rehabilitation tool by determining the attitudes, awareness, opinions and experiences of physiotherapists, and older people towards exergames. [Subjects and Methods] A cross-sectional study was conducted and two short self-developed questionnaires (for physiotherapists and older people) were distributed in three hospitals in Cork (Ireland) to assess the attitudes towards and familiarity with exergames among physiotherapists and older people. The data were analysed using Microsoft Excel version 2013. [Results] The results show that a lot of older people have seen exergames devices but have not attempted to play them. This may indicate a lack of interest in or information about these devices and how to use them. With regard to the second group, physiotherapists underestimate older people's knowledge about exergames. [Conclusion] Older people were not very familiar with exergames but they were willing to try them. In addition, despite physiotherapists being familiar with exergames, they see them as an additional tool that will not replace or change any traditional exercise methods.

The awareness of healthcare staff towards post-stroke cognitive impairment: a cross sectional study.

[Purpose] This study aimed to determine the awareness amongst healthcare staff of post-stroke cognitive impairment in a university teaching hospital and supporting stroke rehabilitation unit. [Subjects and Methods] A cross sectional study was employed to collect data from 20 healthcare staff about post-stroke cognitive impairment. This study was conducted in Ireland at two sites, the Acute Stroke unit in Cork University Hospital, and the Stroke Rehabilitation unit and Assessment and Treatment Centre in St. Finbarr's Hospital. [Results] Approximately 75% of participants felt that they had knowledge about post-stroke cognitive deficits, with around 50% of them having patients with persistent cognitive decline between 40% and 60%. Most participants (70%) agreed that cognitive function should be routinely assessed and the majority (85%) discussed the potential impact of post-stroke cognitive deficits with patients and their families. However, some participants need to be aware of post-stroke cognitive deterioration. [Conclusion] Although there was evidence of good practice, a small number of healthcare staff felt that they did not have sufficient knowledge about post-stroke cognitive deficits. Thus, further professional education should be provided to improve the knowledge of healthcare staff about potential cognitive impairments after stroke.

Effect of pulsed high intensity laser therapy on delayed caesarean section healing in diabetic women.

[Purpose] The objective of this study was to determine the effect of pulsed high intensity laser therapy on delayed caesarean section healing in diabetic women. [Subjects and Methods] This study was conducted on forty diabetic women with delayed caesarean wound healing, ranging in age from 28 to 38 years. They were randomly assigned into two groups; the group I (n=20) received pulsed high intensity laser therapy for 6-weeks, 3 times per week plus standard medical treatment for treatment of diabetes and caesarean wound patients, the group II (n=20) received sham laser treatment for 6 weeks, 3 times per week plus standard medical treatment for treatment of diabetes and caesarean wound patients. The wound size and appearance in all participants were measured by the tracing method and pressure sore status tool before and after the 6-week treatment. [Results] Pulsed high intensity laser therapy produced a significant difference in wound size and appearance in comparison to the sham laser treatment in diabetic women with delayed caesarean wound healing. [Conclusion] Pulsed high intensity laser therapy is effective in the treatment of delayed caesarean section healing in diabetic women.

Efficacy of high intensity laser therapy in the management of foot ulcers: a systematic review.

[Purpose] The aim of this systematic review was to assess the efficacy of high intensity laser therapy (HILT) on wound surface area in patients with foot ulcers. [Methods] Four databases including PubMed, MEDLINE, the Cochrane library, and the Physiotherapy Evidence Database (PEDro) were searched up to the end of April 2018 to identify relevant studies. Studies were included if they met the following criteria: randomised controlled trial (RCT), assessed the efficacy of HILT in patients with foot ulcers, evaluated wound surface area, and written in English language with available full text. The PEDro scale was used to evaluate the quality of studies. [Results] A total of three RCTs met the inclusion criteria, with two studies of the efficacy of HILT in adult patients with diabetic foot ulcers and one in spina bifida children with neuropathic foot ulcers. According to the PEDro scale assessment, all three studies were rated as a fair quality. All studies found that HILT provided significantly better outcomes compared to sham laser or standard medical therapy. [Conclusion] This systematic review suggests that HILT is an effective modality for wound healing in patients with foot ulcers, but further large-scale studies are required to confirm its efficacy.

Factors affecting the extent of utilization of physiotherapy services by physicians in Saudi Arabia.

[Purpose] To investigate physicians' attitudes, opinions and experiences towards physiotherapy services as well as to identify the potential factors that may affect the extent of utilization of physiotherapy services (based on physicians' beliefs) in Saudi Arabia (SA). [Subjects and Methods] A cross-sectional study was conducted. [Results] A total of 108 respondents met the inclusion criteria. The respondents' attitude towards physiotherapy was slightly low (53.5%), while their opinions and experiences of physiotherapy indicated some important issues. For example, 50% of them believed that physiotherapists did not create a good awareness about physiotherapy services and 55.5% admitted that they did not have enough information about physiotherapy services. The most potential factor reported by physicians that may affect the extent of utilization of physiotherapy services was the lack of physiotherapist's skills and knowledge to assess and treat patients (55.3%), followed by the limited knowledge of physicians regarding the types of physiotherapy services (44.5%) and the lack of cooperation between physicians and physiotherapists (40.7%). [Conclusion] There were some factors that limited the extent of utilization of physiotherapy services in SA. Physiotherapy academics and clinicians should attempt to change physicians' negative attitudes, promoting awareness to provide them with a better understanding of physiotherapy services.

The impact of closed versus open kinetic chain exercises on osteoporotic femur neck and risk of fall in postmenopausal women.

[Purpose] This study aimed to investigate how closed and open kinetic chain exercises differed in their impact on bone mineral density (BMD) and fall risk in postmenopausal women with osteoporosis. [Subjects and Methods] The research sample consisted of 40 postmenopausal women with osteoporosis with ages between 51 and 58 years old. They were divided at random into two groups of 20 each, respectively receiving closed and open kinetic chain exercises. These exercises were administered three times per week over a period of four sequential months. Prior to and following the treatment, Dual X-ray Absorptiometry (DEXA) was used to measure the BMD of the femur neck in every participant, while the Biodex Stability System (BSS) was used to estimate how likely each participant was to sustain a fall. [Results] The strongest effect on BMD and fall risk was recorded by the closed kinetic chain exercise. [Conclusion] Osteoporotic postmenopausal women should be prescribed closed kinetic chain exercise to diminish the effects of the disease and minimise their risk of fall.

Cognitive behavioural therapy and pain coping skills training for osteoarthritis knee pain management: a systematic review.

[Purpose] To investigate the effectiveness of cognitive-behavioural therapy (CBT) and pain coping skills training (PCST) on pain level in adults with osteoarthritis of the knee (KOA) in comparison with usual care. [Subjects and Methods] Five databases were systematically searched for relevant randomised controlled trials (RCTs) according to the selected eligibility criteria (inception to June 7, 2016). PEDro scale was used to assess the validity of included studies. [Results] Four studies met the inclusion criteria and all studies had high methodological quality. The total number of participants was 665 across the four included studies. All participants had been diagnosed with KOA (clinical and radiographic evaluation). The majority of the population were female (71.13%). The interventions utilised were: CBT, CBT for insomnia (CBT-I), PCST, and PCST combined with behavioral weight management (BWM) in one study and with exercise in another study. The outcome measure for pain in KOA was the WOMAC scale. Overall, three studies have reported clinical improvement in KOA pain perception after 12-month follow-up time point. [Conclusion] This review has recognised the need for future studies that have rigorous methodological quality, and investigate the effect of mutual CBT and PCST protocols on KOA pain and pain-related functional and psychological abilities.

The effectiveness of short-term high-intensity exercise on ventilatory function, in adults with a high risk of chronic obstructive pulmonary disease.

[Purpose] This study sets out to investigate whether a short-term high-intensity arm ergometer exercise plan can be of benefit to adults whose poor ventilatory function places them at risk of developing chronic obstructive pulmonary disease. [Subjects and Methods] A pre-experimental design with a convenience sample was employed. The study enrolled 30 adult smokers, aged between 18-25 years old, all of whom were at a high risk of chronic obstructive pulmonary disease. The participants did a daily 20-minute high-intensity arm ergometer exercise, at 75% target heart rate, at the same time over a period of three days. The forced vital capacity test manoeuvre was carried out before the sessions, and once all three had been done. [Results] The study demonstrated a sizeable increase in the mean values of forced vital capacity and forced expiratory volume in one second. The mean values of expiratory volume in one second/forced vital capacity as well as peak expiratory flow rate were not significant statistically. [Conclusion] Although further studies, using larger sampling groups, need to be carried out, this research demonstrates that adults at high risk of chronic obstructive pulmonary disease improve lung function by following short-term high-intensity arm ergometer exercise.

Efficacy of high intensity laser therapy in the treatment of male with osteopenia or osteoporosis: a randomized placebo-controlled trial.

[Purpose] To investigate the effect of high intensity laser therapy, alone or combined with exercise on pain, health related quality of life and fall risk in male with osteopenia or osteoporosis. [Subjects and Methods] 100 male patients with osteopenia or osteoporosis participated in the study. They had T-scores ≤-1.5. Patients were randomly assigned into four groups and treated with laser plus exercise, placebo laser plus exercise, laser alone and placebo laser in groups I, II, III, and IV respectively. Laser was applied to the lower back and hip regions. Exercises included aerobic exercises, weight-bearing, flexibility, and strengthening and balance exercises. Treatment were performed 3 times/week for 12 weeks. The measured outcomes were pain, health related quality of life and fall risk. [Results] All measured outcomes were significantly decreased post-treatment in all treatment groups. Laser plus exercises showed a higher significant effect than exercises with a least significant effect in the laser group in reduction of pain and quality of life. [Conclusion] High intensity laser is an effective modality for male patients with osteopenia or osteoporosis. Laser combined with exercise is more effective than exercises or laser alone in decreasing pain, fall risk an increasing quality of life after 12 weeks of treatment.

The effectiveness of physiotherapy interventions for sacroiliac joint dysfunction: a systematic review.

[Purpose] The aim of this study is to investigate the effectiveness of physical therapy interventions in the treatment of sacroiliac joint dysfunction (SIJD). [Subjects and Methods] MEDLINE, PUBMED, CINAHL, AMED, PEDro, and CIRRIE databases were searched and only relevant data from studies that matched the inclusion criteria were included. CASP tools for critical appraisal were used to assess the quality of studies included. [Results] Nine articles met the inclusion criteria, of which, three examined the effect of exercise on SIJD, three used kinesio tape and four studies examined the effect of manipulation. Various outcomes were used including the visual analogue pain scale (VAS), Oswestry disability questionnaire (ODQ), numerical pain rating scale (NPRS) and pelvic position measurement (PALM, pelvimeter and photogrammetry). The quality of included studies ranged from low to average as the CASP tools revealed several limitations that affect the validity of the studies. The results showed that physiotherapy interventions are effective in reducing pain and disability associated with SIJD, with manipulation being the most effective approach and most commonly used within physical therapy clinics. [Conclusion] Manipulation, exercise and kinesio tape are effective in the treatment of pain, disability and pelvic asymmetry in SIJD.

High-intensity laser therapy versus pulsed electromagnetic field in the treatment of primary dysmenorrhea.

[Purpose] To determine the efficacy of high intensity laser therapy (HILT) versus pulsed electromagnetic field (PEMF) in the treatment of primary dysmenorrhea. [Subjects and Methods] This was a randomized clinical trial that included 52 girls diagnosed with primary dysmenorrhea and who were assigned randomly into two groups of equal numbers. The treatment was three sessions every cycle for three consecutive cycles where group (A) included those participants treated with HILT 15 min/session and group (B) those who were treated with PEMF 30 min/session. All patients were evaluated before starting the treatment as well as after the end of treatment by present pain intensity scale and the prostaglandin level in blood and pain relief scale at the end of treatment for both groups. [Results] The results showed a significant decrease in the severity of pain, statistically significant decrease in prostaglandin level in blood, and a statistically significant pain alleviation in both groups. With comparison between both groups there was a statistically significant decrease in the severity of pain, significant decrease in the blood levels of PGF2α, in group (A) than group (B). [Conclusion] Both HILT and PEMF are effective in the treatment of primary dysmenorrhea with HILT being superior to PEMF.

Physiotherapists' awareness and use of red flags for the assessment of low back pain in Saudi Arabia.

BACKGROUND: Physiotherapists must identify potential red flags that may impede recovery and function in individuals with low back pain (LBP) or put them at risk. OBJECTIVES: This study aimed to (1) investigate physiotherapists' awareness and use of red flags for individuals with LBP in Saudi Arabia and (2) identify factors associated with their awareness and use of LBP red flags. METHODS: This cross-sectional study collected data using an anonymous online questionnaire (February-July 2023). It included physiotherapists working in private/public hospitals in Saudi Arabia. The questionnaire asked about the participants' characteristics, their awareness of LBP red flags, and their use of red flags for LBP assessment. RESULTS: A total of 643 participating physiotherapists (26.2 ± 3.8 years), 63.8% of whom were females, completed the survey. Most participants (94.4%) had adequate awareness of LBP red flags, and more than half (61%) had good utilization of red flags when assessing individuals with LBP. There was a positive correlation between the physiotherapists' awareness and use of LBP red flags. CONCLUSION: The majority of the participating physiotherapists in Saudi Arabia were aware of LBP red flags, and many reported to have good use of red flags in clinical practice when assessing and managing individuals with LBP.
