The Effectiveness of Exercise on Reducing the Angle of Kyphosis
The Effectiveness of Kyphosis-specific Exercise on Reducing the Angle of Kyphosis Among Chinese Older Adults With Thoracic Hyperkyphosis - a Randomized Control Trial
Thoracic hyperkyphosis, an exaggerated curvature between the first thoracic vertebra body (T1) and the 12th thoracic vertebra body (T12), has a high prevalence among older adults. The cross-sectional study conducted by the Principal Investigator found 72% of older adults in the Chinese community have thoracic hyperkyphosis.
Thoracic kyphosis has been found having negative effects on self-image, physical function, respiratory function, pain, balance, and gait performance. Treatment options of thoracic hyperkyphosis included surgery, peptides injection, menopausal hormone therapy, bracing, traditional Chinese medicine therapies, and exercise.
The previous studies reported that different types of exercise such as strength training, pilates, yoga, and corrective exercise were effective in reducing the thoracic hyperkyphosis. However, the previous studies either excluded older adults who have exercise habits or lack of information about participants' daily activity levels. Besides, all the group spine exercise interventions in previous studies were delivered by professional trainers or physical therapists in the form of face-to-face exercise classes.
The current RCT will be conducted to provide kyphosis-specific exercise in the form of short video and face to face exercise classes as the intervention to Chinese older adults with thoracic hyperkyphosis. The RCT can test the effects of such kyphosis-specific exercise intervention on the angle of kyphosis, physical performance, pain, and self-image among Chinese older adults with thoracic hyperkyphosis. The investigator hypotheses that older adults receive kyphosis-specific exercise intervention (video and exercise class) have reduced the angle of kyphosis. And older adults receive kyphosis-specific exercise intervention (video and exercise class) have decreased pain, better self-image, and improved overall physical performance.

Detailed Description
Thoracic hyperkyphosis, an exaggerated curvature between the first thoracic vertebra body (T1) and the 12th thoracic vertebra body (T12), has a high prevalence among older adults. The cross-sectional study conducted by the Principal Investigator found 72% of older adults in the Chinese community have thoracic hyperkyphosis.
Thoracic kyphosis has been found having negative effects on self-image, physical function, respiratory function, pain, balance, and gait performance. Treatment options of thoracic hyperkyphosis included surgery, peptides injection, menopausal hormone therapy, bracing, traditional Chinese medicine therapies, and exercise.
The previous studies reported that different types of exercise such as strength training, pilates, yoga, and corrective exercise were effective in reducing the thoracic hyperkyphosis. However, the previous studies either excluded older adults who have exercise habits or lack of information about participants' daily activity levels. Besides, all the group spine exercise interventions in previous studies were delivered by professional trainers or physical therapists in the form of face-to-face exercise classes.
The exercise protocol used by the current RCT was based on that developed by Katzmen and team. The previous studies using the same protocol reported three to five degrees decrease in the angle of kyphosis. Current RCT provides kyphosis-specific exercise in the form of short video and face to face exercise classes. The intervention of the proposed study contains two parts. One is the group kyphosis-specific exercise class given by a certified physical trainer. Another is the home practice following kyphosis-specific exercise videos. The intervention arrangement is : 1. Group learning and practice: a 1-hour kyphosis-specific exercise training session will be provided two times in the first week; 2. Weekly follow-up: a 1-hour kyphosis-specific exercise will be conducted with reinforcement of learning and remedial teaching by a certified physical trainer once a week for five consecutive weeks after the group learning and practice; 3. Self-practice: the participant will following the kyphosis-specific exercise videos doing self-practice every day for the whole intervention period lasting 6 weeks.
The group kyphosis-specific exercise class will be led by a licensed physical trainer and a trained assistant. The participant to instructor (assistant) ratio will no less than 5:1. The content of kyphosis-specific exercise videos is the same as an exercise class.
The participants are to be selected from the communities located in different regions in Wuhan by convenient sampling. Every potential participant will have a trained research assistant responsible for explaining the RCT details with the information sheet and re-assuring the respondents that data collected in the study will be kept strictly confidential, and then seeking permission for conducting the screening. The potential participants will be screened according to inclusion and exclusion criteria. The eligible participants will sign the written consent and accomplish the baseline questionnaire and assessments (T0). After that, the participant will be randomly divided into the intervention group or the control group.
A block randomization method will be used. The investigator will randomly select block sizes such as two, four, or six, to make randomization sequences for 156 participants (sample size calculation results). Then randomization sequences will be printed and placed in a sequentially numbered opaque sealed envelope. After older adult sign consent and finishing the baseline questionnaire and assessments, the researcher will open the envelope according to the numbered sequence for the grouping allocation.
The intervention group will receive a group kyphosis-specific exercise class, kyphosis-specific exercise video, and a logbook. Before every exercise class, the researcher will send them time and location as reminders. Class attendance is recorded every time. The participants are asked to record the time of home kyphosis-specific exercise practice and other daily exercises. The participants will also be encouraged to write down questions or comments in the logbook. The investigator will check the logbook and respond once a week. The Control group will receive a booklet introducing general health education material, and a logbook recording the time of daily exercises. After the end of 6 weeks of intervention, all participants will be invited to finish the postintervention assessment (T1). The data will be analyzed according to the intention to treat after T0 and T1.

The kyphosis-specific exercise is based on the protocol published by Katzman and team in 2016. It includes warm-up, back muscle strength training, spine mobility training, spine alignment training, and stretching. The class will last around 60 minutes. The exercise videos have the same content as the kyphosis-specific exercise class. The participants are asked to practice everyday at home following the videos. |
