Is the occiput-wall distance valid and reliable to determine the presence of thoracic hyperkyphosis?

The Association Between Physical Function and Hyperkyphosis in Older Females: A Systematic Review and Meta-analysis

BACKGROUND AND PURPOSE

Thoracic hyperkyphosis may adversely influence physical function in older adults, but the literature is mixed and confounded by possible sex differences. This systematic review and meta-analysis aimed to examine the association between hyperkyphosis and physical function in older females.

METHODS

Scopus, ISI Web of Science, Cochrane Library, PubMed, CINAHL, and PEDro databases were searched through 2021 for studies that included measures of thoracic hyperkyphosis and physical function with extractable data for women older than 60 years. Studies were excluded if they were qualitative, case reports, case series, ecological studies, reviews, or were not published in English. The study quality and risk of bias were assessed using checklists from the National Heart, Lung, and Blood Institute. Data were synthesized using Cohen's d effect size and 95% confidence interval (CI), and random-effects models were used for the meta-analyses.

RESULTS AND DISCUSSION

Three cohort and 22 cross-sectional studies of fair to good quality met the inclusion criteria. Eight studies reporting single-group data showed a moderate association between greater kyphosis angles and lower physical function ( d = -0.57; 95% CI -0.73, -0.40). Fourteen studies reporting 2-group data showed a large negative effect on physical function for groups with greater kyphosis angles ( d = -1.16; 95% CI -1.53, -0.78). Three studies that reported multivariate data also tended to show negative associations between physical function and hyperkyphosis. Limitations include a relative lack of causal evidence; confirming causation requires additional longitudinal studies. Studies have assessed various physical function categories, including strength, gait, and balance. Future studies could determine the categories of function most affected so that preventive interventions could target hyperkyphosis appropriately.

CONCLUSIONS

Hyperkyphosis was associated with lower physical function in older women. Three cohort studies suggest that greater kyphosis angles may predict greater loss of physical function over time. These results imply that therapies that help to minimize hyperkyphosis may help preserve function in older women.

The seventh cervical vertebra is an appropriate landmark for thoracic kyphosis measures using distance from the wall

Background

Hyperkyphosis is frequently found nowadays due to the change in current lifestyles and age-related system decline. A simple hyperkyphosis measurement can be made easily using the perpendicular distance from the landmark to the wall. However, the existing evidence applied two different landmarks [occiput and the seventh cervical vertebra (C7)] and the measurement using rulers was susceptible to error due to their misalignment.

Objective

To assess an appropriate landmark for thoracic kyphosis measurement using distance from the wall (KMD), by comparing between occiput and C7, as measured using rulers and verified using data from a specially developed machine, the so-called infrared-gun kyphosis wall distance tool (IG-KypDisT), and the Cobb angles.

Methods

Community-dwelling individuals with a risk of thoracic hyperkyphosis (age ≥ 10 years, n = 43 ) were cross-sectionally assessed for their thoracic hyperkyphosis using the perpendicular distance from the landmarks, occiput and C7, to the wall using rulers and IG-KypDisT. Then the Cobb angles of these participants were measured within seven days.

Results

The outcomes from both landmarks differed by approximately 0.8 cm (p =  0.084). The outcomes derived from C7 were more reliable (ICCs>0.93, p < 0.001), with greater concurrent validity with the radiologic data (r =  0.738, p < 0.001), with the overall variance predicted by the regression models for the Cobb angles being higher than that from the occiput (47-48% from C7 and 38-39% from occiput). The outcomes derived from rulers and IG-KypDisT showed no significant differences.

Conclusion

The present findings support the reliability and validity of KMD assessments at C7 using rulers as a simple standard measure of thoracic hyperkyphosis that can be used in various clinical, community, and research settings.

Good construct validity of the CT Syndesmophyte Score (CTSS) in patients with radiographic axial spondyloarthritis

OBJECTIVES

To assess construct validity of the CT Syndesmophyte Score (CTSS) for the measurement of structural spinal damage in patients with radiographic axial spondyloarthritis.

METHODS

Low-dose CT and conventional radiography (CR) were performed at baseline and 2 years. CT was assessed with CTSS by two readers and CR with modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS) by three readers. Two hypotheses were tested: (1) syndesmophytes scored with CTSS are also detected with mSASSS at baseline or 2 years later; (2) CTSS is non-inferior to mSASSS in correlations with spinal mobility measures. Presence of a syndesmophyte was determined per reader per corner for all anterior cervical and lumbar corners on CT at baseline and CR at baseline and 2 years. Correlations of CTSS and mSASSS with six spinal/hip mobility measurements plus Bath Ankylosing Spondylitis Metrology Index (BASMI) were tested.

RESULTS

Data from 48 patients (85% male, 85% HLA-B27+, mean age 48 years) were available for hypothesis 1 and 41/48 were available for hypothesis 2. At baseline, syndesmophytes were scored with CTSS in 348 (reader 1, 38%) and 327 (reader 2, 36%) corners out of 917. Of these, depending on reader pairs, 62%-79% were also seen on CR at baseline or after 2 years. CTSS correlated well (r_s 0.46-0.73), and with higher correlation coefficients than mSASSS (r_s 0.34-0.64), with all spinal mobility measures and BASMI.

CONCLUSIONS

The good agreement between syndesmophytes detected by CTSS and mSASSS and the strong correlation of CTSS with spinal mobility support the construct validity of the CTSS.

Intraoperative stretching microbreaks reduce surgery-related musculoskeletal pain in otolaryngologists

OBJECTIVE

The purpose of this study was to examine the role intraoperative otolaryngology stretching microbreak (OSMB) has on musculoskeletal (MSK) pain and discomfort in otolaryngologists.

BACKGROUND

Otolaryngology procedures subject surgeons to significant amounts of pain and strain over their years of training. MSK pain is a serious concern for otolaryngologists' career longevity as well as their general wellbeing.

METHODS

Participants from two different hospitals and one private practice were recruited to participate in this study. An initial ergonomic survey was obtained to assess baseline MSK pain, and its subjective impact on operative performance. The participants then completed three control days without OSMB exercises, followed by three intervention days with OSMB exercises which were completed at 20-40 minute intervals. Preoperative and postoperative pain rating surveys were completed before and after each procedure and at the end of the day to determine changes in pain and/or discomfort.

RESULTS

Ten otolaryngologists (50 % men, 50 % women; mean age 35.6 years) participated in this study. Half of the participants indicated that they were concerned their pain would limit their ability to operate in the future. 70 % of participants indicated that they have not attempted to treat this pain and 60 % did not try any stretching exercises outside the operating room (OR) to mitigate their symptoms. Participants reported neck, upper back, and lower back to be the primary MSK discomfort. OSMB improved participants' pain scores in neck, shoulders, hands, and lower back pain (p < 0.05).

CONCLUSION

MSK pain has shown to be a serious concern for the ability of otolaryngologists to continue performing surgery in the future. OSMB may be an effective strategy that can be implemented by otolaryngologists intraoperatively to improve MSK pain and overall well being.

Effects of Classical Breathing Exercises on Posture, Spinal and Chest Mobility among Female University Students Compared to Currently Popular Training Programs

Worldwide, university students’ physical health and posture are declining due to a sedentary lifestyle. The aim of our study was to evaluate the effectiveness of physiotherapeutic breathing exercises on posture and spinal mobility among healthy female university students compared to other training methods. Sixty-one female students of the University of Debrecen were assigned to breathing exercise (BE; n = 15), yoga (Y; n = 16), Pilates (P; n = 15) programmes and interval-training (IT; n = 15). Each training session lasted one hour, performed twice a week for 7 weeks. Students were assessed using standardized clinical tests. All programmes resulted in significant improvement in chest expansion. Results of Schober’s test showed substantial improvement using BE (p < 0.05), Y, P (p ≤ 0.01) programmes. Significant changes in occiput-to-wall distance (Y, P p ≤ 0.01) (BE p ≤ 0.001) were observed in three groups except the IT group. Fingertip-to-floor test (Y, P p < 0.05) results showed significant changes in two groups. The most outstanding effects on lateral flexion were achieved using BE (right, left p ≤ 0.001) programme. A comparison with results achieved using yoga and Pilates revealed that the physiotherapeutic breathing exercise programme is an equally effective method to significantly improve spinal mobility and correct postural problems in healthy young women.

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.

The Influence of Nordic Walking on Spinal Posture, Physical Function, and Back Pain in Community-Dwelling Older Adults: A Pilot Study

Nordic walking is an increasingly popular form of exercise among the elderly. Using poles is thought to facilitate a more upright posture; however, previous studies primarily investigated the effects of Nordic walking on respiratory function and physical fitness. The aims of this study were to investigate the influence of Nordic walking on spinal posture, physical functions, and back pain in community-dwelling older adults. Thirty-one community-dwelling older adults aged ≥ 60 years participated in a twice weekly Nordic walking training program for 12 weeks. The outcome measures, including spinal posture, physical functions, back pain, and the strength and endurance of back extensor muscles were assessed before and after a 12-week program. After training, spinal posture, back pain, and the strength and endurance of back extensor muscles did not show any statistically significant changes. Among the seven clinical tests of physical function, only the 30 s arm curl test, the 30 s chair stand test, and the single leg stance test showed significant improvements. Nordic walking has limited influence on age-related hyperkyphosis and back pain, but may be effective for physical function. The results of this study can provide useful information for people involved in the prevention and treatment of physical dysfunction in community-dwelling older adults.
