Thoracic Hyperkyphosis: A Survey of Australian Physiotherapists

Survey of Knowledge, Attitudes, and Levels of Confidence Regarding Age-Related Hyperkyphosis and Its Management among Thai Physiotherapists

BACKGROUND

Thorough knowledge of the management of age-related hyperkyphosis is crucial to physiotherapists' effective handling of complex spinal deformities.

OBJECTIVE

This cross-sectional study investigated the knowledge, attitudes, and confidence of Thai physiotherapists regarding age-related hyperkyphosis.

METHODS

An online questionnaire with demographic, work-related, knowledge, attitude, and confidence questions was employed. The data analysis involved descriptive statistics, chi-square tests, and independent t-tests.

RESULTS

Complete responses were obtained from 314 physiotherapists. The correct responses amounted to 68.79% for the definition, 90.00% for causes, 14.97% for age of onset, 22.38% for prevalence, and 64.65% for the gold-standard diagnosis of hyperkyphosis. Most of the diagnostic methods involved visual examination. The respondents reported that hyperkyphosis disrupts respiratory function. The aim of treatment, according to 88.85%, was to increase spine mobility. Corrective posture exercises were the most common treatment strategy, but the range of treatments was diverse. Many cited undergraduate education as their primary evidence source. Respondents had conflicting attitudes towards "age-related hyperkyphosis is a normal aging process" but mostly positive attitudes towards the need for physiotherapy treatment. Approximately 22% reported fair confidence in treating hyperkyphosis.

CONCLUSIONS

This study highlights the importance of raising awareness and enhancing knowledge, attitudes, and confidence among physiotherapists to improve care for older adults with hyperkyphosis.

Effects of Stretching or Strengthening Exercise on Spinal and Lumbopelvic Posture: A Systematic Review with Meta-Analysis

BACKGROUND

Abnormal posture (e.g. loss of lordosis) has been associated with the occurrence of musculoskeletal pain. Stretching tight muscles while strengthening the antagonists represents the most common method to treat the assumed muscle imbalance. However, despite its high popularity, there is no quantitative synthesis of the available evidence examining the effectiveness of the stretch-and-strengthen approach.

METHODS

A systematic review with meta-analysis was conducted, searching PubMed, Web of Science and Google Scholar. We included controlled clinical trials investigating the effects of stretching or strengthening on spinal and lumbopelvic posture (e.g., pelvic tilt, lumbar lordosis, thoracic kyphosis, head tilt) in healthy individuals. Effect sizes were pooled using robust variance estimation. To rate the certainty about the evidence, the GRADE approach was applied.

RESULTS

A total of 23 studies with 969 participants were identified. Neither acute (d = 0.01, p = 0.97) nor chronic stretching (d=-0.19, p = 0.16) had an impact on posture. Chronic strengthening was associated with large improvements (d=-0.83, p = 0.01), but no study examined acute effects. Strengthening was superior (d = 0.81, p = 0.004) to stretching. Sub-analyses found strengthening to be effective in the thoracic and cervical spine (d=-1.04, p = 0.005) but not in the lumbar and lumbopelvic region (d=-0.23, p = 0.25). Stretching was ineffective in all locations (p > 0.05).

CONCLUSION

Moderate-certainty evidence does not support the use of stretching as a treatment of muscle imbalance. In contrast, therapists should focus on strengthening programs targeting weakened muscles.

Comparison of the Radiographic and Clinical Outcome Changes in Patients With Spinal Deformity Before and After Stretching DanceExercise: A Systematic Review and Meta-Analysis

OBJECTIVE

This study aimed to compare radiographic and clinical outcomes of scoliosis and thoracic hyperkyphosis before and after stretching-based exercises.

METHODS

Embase, PubMed, Cochrane Library, Web of Science, and Scopus databases were comprehensively searched for relevant studies from their inception to June 2022. Radiographic outcomes, including the Cobb angle of the main curve and thoracic kyphosis, and clinical outcomes, including the angle of trunk rotation (ATR), chest expansion, Numeric Rating Scale (NRS), and Scoliosis Research Society-22 Patient Questionnaire (SRS-22), were extracted. Pooled and subgroup analyses were performed using random or fixed-effects models based on I2 heterogeneity.

RESULTS

In total, 334 patients from ten studies, including 255 patients with scoliosis and 79 patients with thoracic hyperkyphosis, were included in the meta-analysis. After stretching, the pooled results showed that the Cobb angle of the main curve and thoracic kyphosis significantly decreased (P < 0.001) in patients with scoliosis, and thoracic kyphosis, respectively. Angle of trunk rotation (ATR) decreased significantly (P = 0.003), and chest expansion improved significantly (P = 0.04) after stretching-based exercise. In addition, our pooled results showed that the NRS score was significantly reduced (P < 0.001) and that the SRS-22 scores of mental health (P = 0.003) and self-perceived image (P < 0.001) were significantly increased after stretching.

CONCLUSIONS

Partial correction can be achieved using stretching-based exercises. Moreover, stretching-based exercises can reduce pain in patients and improve their quality of life. However, the optimal duration required further elucidation.

Monitoring Expression of Balance during Therapy in Children with Postural Disorders

In the literature, we find information about the impact of changes in the shape of the spine on the efficiency of equivalent reactions, and we also find information about the methods and effects of physiotherapy in improving equivalent reactions. However, there is a lack of publications showing the process of changes taking place over time and defining their nature at individual stages of treatment. The aim of this study is to present the process of monitoring the expression of balance in patients aged 8-12 years with postural disorders, in the course of the therapeutic process. The shape of the spine and the efficiency of equilibrium reactions in standing posture and during gait were assessed in all the subjects. The subjects were put into two groups: with a shape-of-spine disorder and without one. The recommended set of therapeutic activities in home conditions lasted about 20 min and was performed by the child with a parent's supervision. The therapeutic program was based on elements of neurophysiological methods: Vojta and PNF. The following parameters were measured: the maximum movement of the center of pressure (CoP) in the frontal plane during gait, the maximum movement of the CoP in the sagittal plane, the movement of the CoP in the frontal plane in static conditions and the movement of the CoP in the sagittal plane in static conditions. Six statistically significant differences were recorded, and all of them were related to measurement I. The Friedman test result was statistically significant for all the indexes. Post hoc analyses were performed using the Dunn-Bonferroni test. The children with shape-of-spine disorders had a lower efficiency of equivalent reactions in relation to the children without disorders. The therapy with the application of neurophysiological methods in the treatment of shape-of-spine disorders improved equilibrium reactions in these patients. Long-lasting and thorough observations of the therapeutic process in children with shape-of-spine disorders should include the monitoring of the efficiency of equilibrium reactions.

A randomized controlled study of the effect of functional exercises on postural kyphosis: Schroth-based three-dimensional exercises versus postural corrective exercises

PURPOSE

To compare the effects of postural corrective and Schroth-based three-dimensional exercises on thoracic kyphosis angle (TKA), lumbar lordosis angle (LLA), balance and quality of life (QoL) in individuals with postural kyphosis.

METHODS

This was a single-blind randomized controlled clinical trial with a total of 63 subjects (57 women, 6 men) with TKA of ≥40°. Subjects were separated into three groups: postural corrective exercise group (PCEG), Schroth-based three-dimensional exercise group (SBEG) and control group (CG). Participants in the exercise groups participated in the exercise program twice a week for eight weeks under the supervision of a physiotherapist: CG performed no exercise but was generally informed. The primary outcome variable was TKA. Secondary outcome variables were LLA, balance and QoL.

RESULTS

After the functional exercise programs, TKA (mean change for PCEG, SBEG: -9.71, -14.76, p < 0.001), static postural stability index overall (-0.22, -0.40, p < 0.05), and QoL (-0.41, -0.37, p < 0.001) significantly improved in both training groups compared with CG. The LLA (-3.95, p = 0.003) was significantly lower in the SBEG group than in CG.

CONCLUSION

This study demonstrated that Schroth-based three-dimensional exercises are an effective treatment for individuals with postural kyphosis and have a large effect size that improves TKA, LLA, balance and QoL. Clinical trial registration number: NCT03706495 Implications for rehabilitationEight weeks of postural corrective or Schroth-based three-dimensional functional exercise programs are effective in addressing thoracic kyphosis angle (TKA), balance, and quality of life in individuals with postural kyphosis.An eight-week Schroth-based three-dimensional exercise program was more effective than postural corrective exercises in improving TKA, lumbar lordosis angle, and balance for patients with postural kyphosis.Schroth-based three-dimensional exercise programs could promote balance and spinal health in young adults with thoracic kyphosis.

The Relationship Between the Shape of the Spine and the Width of Linea Alba in Children Aged 6-9 Years. Case-Control Study

INTRODUCTION

Civilization development coupled with contemporary lifestyle leads to a systematic increase in postural disorders. An analysis of factors that may provoke postural disorders indicates that such a stimulus may be the diastasis of the rectus abdominis muscles. Moreover, abnormal activity of the rectus abdominis muscles may affect balance disorders through reduced spinal stabilization and disturbed body statics. There is an increase in body posture abnormalities between the ages of 6 and 9 related to new school duties.

PURPOSE OF THE STUDY

The purpose of the study was to evaluate the relationship between the shape of the spine and the width of the linea alba in children aged 6-9 years.

MATERIAL AND METHOD

The study was designed to evaluate parameters determining the shape of the spine, and the width of the linea alba in healthy children aged 6-9 years. The study participants were divided into two groups based on the width of the linea alba. The study group with the width of the linea alba >10 mm and the control group with the width of the linea alba ≤ 10 mm. The study group were included 37 children and the control group 24 children. The examination of the linea alba width was performed by a radiology specialist using a linear transducer and SAOTE- My Lab Classc-type ultrasound at rest and during contraction of the rectus abdominis muscles. Parameters describing the shape of the spine were measured using the Diers Formetric 4D system: trunk inclination, trunk imbalance, pelvis tilt, pelvic torsion, kyphotic apex, lordotic apex, kyphotic angle, lordotic angle, rotation angle, trunk torsion, lateral deviation. The obtained results were statistically analyzed using a Paired t test for comparison of differences between the results in the study and control groups and Pearson's test to assess the correlation between the width of the linea alba and parameters describing spinal alignment.

RESULTS

In both groups, the parameters describing the shape of the spine did not differ from the norms accepted as typical for the age norm. The only statistically significant difference between the study and control group concerned the trunk inclination, which was negative in the study group, signifying a shift of the entire spine axis backwards beyond the vertical.

CONCLUSIONS

There is a correlation between the shape of spine and the width of the linea alba in terms of selected parameters determining the body posture in the sagittal plane, which concern: the position of the lumbar lordotic apex, trunk inclination and the depth of the lumbar lordotic angle. The width of the linea alba is not explicitly related to abnormalities of pelvic and spinal alignment in the frontal and transverse planes.

Decreasing thoracic hyperkyphosis - Which treatments are most effective? A systematic literature review and meta-analysis

BACKGROUND

A variety of treatments aim to reduce thoracic hyperkyphosis in adults, thereby improving posture and reducing possible complications.

OBJECTIVE

To investigate the effectiveness of treatments to reduce thoracic hyperkyphosis.

DESIGN

Systematic review and meta-analysis.

METHODS

MEDLINE, EMBASE, CINAHL, and CENTRAL were searched from inception to March 2021. Two authors independently selected randomised controlled trials assessing the effectiveness of treatments to reduce thoracic hyperkyphosis in adults. Raw data on mean change in thoracic kyphosis were extracted and standardised mean differences (SMD) calculated. Meta-analysis was performed on studies homogenous for study population and intervention. Strength of evidence was assessed using GRADE.

RESULTS

Twenty-eight studies were included, with five meta-analyses performed. Low to moderate-quality evidence found structured exercise programs of three-months duration or less effective in reducing thoracic hyperkyphosis in younger (SMD -2.8; 95%CI -4.3 to -1.3) and older populations (SMD -0.3; 95%CI -0.6 to 0.0). Low-quality evidence found bracing for three months or more effective in older participants (SMD -1.0, 95%CI -1.3 to -0.7). A single study demonstrated the effectiveness of multimodal care in younger participants. The available evidence suggests multimodal care, structured exercise programs over three months duration, and taping in older adults, and biofeedback and muscle stimulation in younger adults, are ineffective in reducing thoracic hyperkyphosis.

CONCLUSION

Low to moderate-quality evidence indicates that structured exercise programs are effective to reduce thoracic hyperkyphosis. Low-quality evidence indicates that bracing is effective to reduce thoracic hyperkphosis in older adults.

Effects of scapular stabilization exercises on posture and muscle imbalances in women with upper crossed syndrome: A randomized controlled trial

BACKGROUND

Scapular stabilization exercises can improve forward shoulder posture in young women. However, the effects of optimal exercise protocols on neck and shoulder postures, scapular muscle imbalance and thoracic kyphosis are still unclear.

OBJECTIVES

To investigate the effects of scapular stabilization exercises on neck and shoulder postures, scapular muscle imbalance and thoracic kyphosis in young women with upper crossed syndrome.

METHODS

Thirty-nine women aged 18-25 years with upper crossed syndrome were recruited. Participants were randomly allocated intotwo groups. The exercise group performed scapular stabilization exercises using elastic bands at 10 repetitions/set, 3 sets/day, and 3 days/week for 4 weeks. The control group did not perform any exercises during the experimental period. The cervical and shoulder angles were evaluated using the Kinovea program. A caliper, handheld dynamometer and flexi ruler were used to evaluate the length of the pectoralis minor, strength of the scapular stabilizer muscles and degree of the mid-thoracic curve, respectively.

RESULTS

The exercise group showed significant differences (p< 0.05) in the increase in cervical and shoulder angle, length of the pectoralis minor, and strength of the scapular muscles, except in the degree of mid-thoracic curve compared to the control group.

CONCLUSION

This study indicated that scapular stabilization exercises can improve forward head and shoulder posture, increase the flexibility of the pectoralis minor and strengthen the scapular muscles.

Effects of obesity on breast size, thoracic spine structure and function, upper torso musculoskeletal pain and physical activity in women

PURPOSE

This study investigated the effects of obesity on breast size, thoracic spine structure and function, upper torso musculoskeletal pain and physical activity participation in women living independently in the community.

METHODS

A total of 378 women were divided into 3 groups (Not Overweight: body mass index (BMI) = 22.5 ± 0.2 kg/m² (mean ± SE); Overweight: BMI = 27.4 ± 0.3 kg/m²; Obese: BMI = 35.4 ± 0.3 kg/m²). Outcome variables of breast volume (mL), thoracic flexion torque (N·m), thoracic kyphosis (degrees), upper torso musculoskeletal pain (score) and time spent in physical activity (min) were calculated and compared among the 3 groups, adjusting for between-group differences in age.

RESULTS

There was a significant main effect of BMI on all outcome variables. Participants classified as Obese displayed significantly larger breasts, had greater thoracic flexion torques and reported less time participating in physical activity relative to the participants who were classified as Not Overweight and Overweight. Participants in the Obese group also displayed significantly more thoracic kyphosis and reported significantly more upper torso musculoskeletal pain compared to their counterparts who were classified as Not Overweight.

CONCLUSION

This study is the first to demonstrate that increased obesity levels were associated with compromised kyphosis and loading of the thoracic spine, as well as increased symptoms of upper torso musculoskeletal pain and reduced time spent in physical activity in women living in the community. We recommend further research to determine whether evidence-based interventions designed to reduce the flexion torque generated on the thoracic spine can improve these symptoms of upper torso musculoskeletal pain and the ability of women with obesity to participate in physical activity.

Can breast characteristics predict upper torso musculoskeletal pain?

BACKGROUND

Several studies have associated a large breast size with an increased prevalence and severity of musculoskeletal pain, particularly pain in the upper torso. Despite this evidence, no research has explored whether breast size or related characteristics are risk factors for upper torso musculoskeletal pain.

METHODS

A backward multiple regression analysis was performed to identify whether characteristics of the breasts and upper torso, as well as physical factors known to be associated with musculoskeletal pain, could predict musculoskeletal pain among a cohort of 378 Australian women aged 18 years and over who had a wide range of breast sizes.

FINDINGS

The model identified that breast volume, age and nipple-to-nipple distance predicted 23% of the variance in upper torso musculoskeletal pain reported by the participants.

INTERPRETATION

Women with a larger breast volume, lower age and a greater nipple-to-nipple distance were predicted to report a higher upper torso musculoskeletal pain score.

Management of Spinal Deformities and Evidence of Treatment Effectiveness

INTRODUCTION

The review evaluates the up-to-date evidence for the treatment of spinal deformities, including scoliosis and hyperkyphosis in adolescents and adults.

MATERIAL AND METHODS

The PubMed database was searched for review articles, prospective controlled trials and randomized controlled trials related to the treatment of spinal deformities. Articles on syndromic scoliosis were excluded and so were the articles on hyperkyphosis of the spine with causes other than Scheuermann's disease and osteoporosis. Articles on conservative and surgical treatments of idiopathic scoliosis, adult scoliosis and hyperkyphosis were also included. For retrospective papers, only studies with a follow up period exceeding 10 years were included.

RESULTS

The review showed that early-onset idiopathic scoliosis has a worse outcome than late-onset idiopathic scoliosis, which is rather benign. Patients with AIS function well as adults; they have no more health problems when compared to patients without scoliosis, other than a slight increase in back pain and aesthetic concern. Conservative treatment of adolescent idiopathic scoliosis (AIS) using physiotherapeutic scoliosis-specific exercises (PSSE), specifically PSSR and rigid bracing was supported by level I evidence. Yet to date, there is no high quality evidence (RCT`s) demonstrating that surgical treatment is superior to conservative treatment for the management of AIS. For adult scoliosis, there are only a few studies on the effectiveness of PSSEs and a conclusion cannot as yet be drawn.For hyperkyphosis, there is no high-quality evidence for physiotherapy, bracing or surgery for the treatment of adolescents and adults. However, bracing has been found to reduce thoracic hyperkyphosis, ranging from 55 to 80° in adolescents. In patients over the age of 60, bracing improves the balance score, and reduces spinal deformity and pain. Surgery is indicated in adolescents and adults in the presence of progression of kyphosis, refractory pain and loss of balance.

DISCUSSION

The available evidence reviewed has suggested that different approaches are needed towards the management of different spinal deformities. Specific exercises should be prescribed in children and adolescents with a Cobb angle in excess of 15°. In progressive curves, they should be used in conjunction with bracing. Clarity regarding differences and similarities is given as to what makes PSSE and PSSR specific exercises. As AIS is relatively benign in nature, conservative treatment should be tried when the curve is at a surgical threshold, before surgery is considered. Similarly, bracing and exercises should be prescribed for patients with hyperkyphosis, particularly when the lumbar spine is afflicted. Surgery should be considered only when the symptoms cannot be managed conservatively.

CONCLUSION

There is at present high quality evidence in support of the conservative treatment of AIS. The current evidence supports the use of PSSE, especially those using PSSR, together with bracing in the treatment of AIS. In view of the lack of medical consequences in adults with AIS, conservative treatment should be considered for curves exceeding the formerly assumed range of conservative indications.There is, however a lack of evidence in support of any treatment of choice for hyperkyphosis in adolescents and spinal deformities in adults. Yet, conservative treatment should be considered first. Yet to date, there is no high quality evidence (RCT`s) demonstrating that surgical treatment is superior to conservative treatment for the management of AIS and hyperkyphosis. Additionally, surgery needs to be considered with caution, as it is associated with a number of long-term complications.

Exercise for improving age-related hyperkyphotic posture: a systematic review

OBJECTIVE

To evaluate previous research to determine if exercise can improve preexisting hyperkyphosis by decreasing the angle of thoracic kyphosis in adults aged ≥45 years.

DATA SOURCES

PubMed, Embase, and the Cumulative Index to Nursing and Allied Health Literature databases were searched for studies related to posture, exercise, and age ≥45 years. Online conference proceedings of the American Society for Bone and Mineral Research, American Physical Therapy Association, and Gerontological Society of America were also searched.

STUDY SELECTION

Two independent reviewers screened the titles and abstracts and selected studies that tested the effect of exercise on measures of kyphosis, or forward head posture, in individuals with hyperkyphosis at baseline (defined as angle of kyphosis ≥40°). Reviews, letters, notes, and non-English language studies were excluded.

DATA EXTRACTION

A pilot-tested abstraction form was used by each reviewer to extract data from each study regarding details of exercise intervention, participant characteristics, safety, adherence, and results. The Cochrane Collaboration's tool for assessing risk of bias was used to assess methodologic quality. Discrepancies on the abstraction forms between the 2 reviewers were resolved by a third reviewer. A formal meta-analysis was not performed.

DATA SYNTHESIS

Thirteen studies were abstracted and included in the review; of these, 8 studies saw improvements in ≥1 measure of posture. The main sources of bias were related to blinding participants and incomplete outcome data. The adherence reported across studies suggests that exercise is an acceptable intervention for individuals with age-related hyperkyphosis.

CONCLUSIONS

The scarcity and quality of available data did not permit a pooled estimate of the effect of exercise on hyperkyphotic posture; however, the positive effects observed in high-quality studies suggest some benefit and support the need for an adequately designed randomized controlled trial examining the effect of exercise on hyperkyphosis.
