Clinical Trial Summary

We propose to conduct a randomized, controlled trial among 100 men and women aged 60 or older with hyperkyphosis to an exercise intervention that includes kyphosis-specific spinal muscle strengthening exercises compared to a usual care control group. The study will be conducted in five waves,with 10 participants in the exercise intervention and 10 participants in the control group in each wave.

Description:

The experimental interventions will be provided in small groups meeting three sessions per week for 6 months. At baseline and 6 months after the intervention, we will measure kyphosis, physical function, spine muscle strength and density, and quality of life. We will assess the effect of the intervention on the co-primary outcomes of kyphosis, modified Physical Performance Test (PPT) and gait speed measured as change over 6 months. We will also assess the effect of the intervention on secondary outcomes of physical function and health-related quality of life, measured as change in Timed Up and Go, Timed Loaded Standing, Six-Minute Timed Walk, the Scoliosis Research Society SRS-30, PROMISe Global Health and physical function and PACE questionnaires. Furthermore, we will investigate whether changes in kyphosis, spinal muscle strength and/or density mediate the effect of the intervention on change in physical function. After the 6-month intervention, both groups will continue their usual activity and we will assess the durability of the effects of the intervention at 1-year follow-up.

Intervention

Behavioral:
• Kyphosis-specific spinal strengthening exercises
Investigator developed the intervention protocol (Kyphosis-specific spinal strengthening exercises) of targeted spine exercises during our pilot study based upon the literature and clinical experience.We standardized the protocol with a written script and a video. Each exercise session will be preceded by light aerobic activity, ended with cool-down and stretching the neck, chest and all extremities. All participants will be carefully monitored to ensure that all exercises will be performed slowly, with correct body alignment and technique to minimize risk of injury.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Effect of Exercise Intervention on Kyphosis	Investigators will measure change in Cobb angle on lateral spine radiograph.	1 year post baseline
Other	Effect of Exercise Intervention on Secondary Measure of Physical Function	Investigators will measure change in physical function with Modified Physical Performance Test (PPT), gait speed, Timed Up and Go, Timed Loaded Standing, 6 minute walk and spinal extensor muscle strength.	1-year post baseline
Other	Effect of Exercise Intervention on Health Related Quality of Life (HRQOL)	Investigators will measure change in HRQOL with the Scoliosis Research Society SRS-30 (self image domain) and PROMIS Physical Function and Global Health questionnaires.	6 month post baseline

Other	Effect of Exercise Intervention on Muscle Strength	Investigators will measure change in spinal muscle strength as measured with a Biodex computerized dynamometer, and spinal muscle density as measured with quantitative computed tomography.	6 month post baseline
Primary	Change in Cobb Angle of Kyphosis	The primary outcome is change in kyphosis from baseline to 6 months, measured using the gold standard Cobb angle of kyphosis derived from standing lateral spine radiographs and a standardized protocol for thoracic kyphosis (T4-T12). The study team performed exploratory analyses using the centroid method for measuring Cobb angle from lateral spine radiograph and the Debrunner kyphometer external measurement of kyphosis. Participants stood barefoot with knees straight and arms supported at 90° of flexion; they were instructed to hold full inhalation for the duration of the scan. Measurements were made by a trained radiologist (BF) who read the radiographs paired by participant but blinded to group allocation. A greater Cobb angle indicates more kyphosis severity.	Baseline and 6 months
Secondary	Change in Modified Physical Performance Test (PPT)	Modified Physical Performance Test (PPT) is a composite measure of physical function in aging adults: 50ft [15.2-m] floor walk, putting on and removing a laboratory coat, picking up a penny from the floor, standing up 5 times from a 40.6cm-high [16in-high] chair without the use of arms, lifting a 7-lb book to a shelf, climbing one flight of stairs, and standing with feet together) and 2 additional untimed tasks (climbing up and down 4 flights of stairs and performing a 360° turn).; The test involves 9 functional items, 4 points per item; the range is 0-36 points, and higher values represent a higher physical performance.	Baseline and 6 months
