Does a Pre-operative Exercise Program Improve Post-operative Outcomes for Fusion Patients

October 6, 2023 updated by: Firoz Miyanji, University of British Columbia

Does a Pre-operative Exercise Program Improve Post-operative Outcomes in Patients Undergoing Spinal Fusion Surgery for Adolescent Idiopathic Scoliosis?

A study found that in 1744 patients undergoing fusion surgery for adolescent Idiopathic scoliosis, 12% had back pain remaining after recovering from surgery. Rehabilitation prior to spine surgery or prehabilitation (prehab), has been shown to reduce costs and improve functional outcomes in patients who have had total hip or total knee arthroplasties. There is a lack of literature looking at prehab in the context of spine surgeries. The purpose of this study is to see if prehab can improve patient outcomes such as decreased pain, decreased length of stay in the hospital, and improved functional outcomes in patients undergoing fusion surgery for adolescent idiopathic scoliosis.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Adolescent idiopathic scoliosis (AIS) is the most common spinal deformity in adolescents and literature suggests that the link between back pain and AIS is underreported. Core stabilization exercises and scoliosis specific exercises have been shown to increase SRS scores related to pain (higher SRS scores indicate lower levels of pain). Additionally, higher SRS scores at pre-op were associated with a lower risk of residual postoperative pain following a fusion surgery. This suggests that preoperative exercise programs should lead to an increase in SRS pain scores post-operatively however, this direct relationship has not been researched. Rehabilitation exercises prior to surgery has been shown to improve functional outcomes in knee and hip arthroplasties however, the rehabilitation preoperatively has not been studies in the context of spine surgeries. The purpose of this study is to evaluate whether the prehabilitation exercise program can improve post-op outcomes including length of stay, decreased pain, decreased length of stay, and improved functional outcomes.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Included patients will have a diagnosis of AIS (ages 11-18). They will have a curve angle requiring surgery and be on the waitlist for surgery.

Exclusion Criteria:

  • Patients will be excluded if they are currently enrolled in a physiotherapy designed exercise program prior to being enrolled in the study.
  • They will be excluded if they have additional medical issues, limiting their ability to participate fully in the exercise program.
  • Individuals with any cognitive disability that affects their ability to complete the questionnaires or follow instructions for the exercise program will also be excluded.

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

  • Primary Purpose: Supportive Care
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Standard of Care Group
Experimental: Prehabilitation Exercise Group
The exercise arm participants will be asked to complete weekly questionnaires which will take around 10 minutes each week and the exercise program which takes 30 minutes each day.
Behavioral: Prehabilitation Exercise Group
A set of core stabilization exercises and scoliosis specific exercises will be given to patients.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Primary Outcome
Time Frame: 2 years
The primary analysis for the primary outcome length of stay is to determine if the prehab program reduces the average length of stay. It will follow the intention to treat approach, which will include all randomized participants retained in the group to which they are allocated. A complete analysis will be conducted to compare the outcomes between the two arms, utilizing the Student's t test or Wilcoxon-Mann-Whitney test, as appropriate for the distribution of the data. If more than 10% of randomized participants have missing length of stay outcomes, the missing data will be imputed using the Last Observation Carried Forward approach, as a sensitivity analysis.
2 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Pain Outcome
Time Frame: 2 years
The pain outcomes will be measured using the Visual Analogue Scale (VAS); a scale ranging from 0 - 10, where 0 indicates no pain, and 10 indicates extreme pain.
2 years
Functional Outcome
Time Frame: 2 years
The functional outcomes will be measured using the Scoliosis Research Society 22-item questionnaire (SRS-22). In this questionnaire, responses correspond to numbers 1 - 5, where 1 is the worst possible outcome and 5 is the best possible outcome. There will be a total SRS-22 score (average of all the scores) and five sub scores. The sub scores will be divided into five groups: function, pain, self-image, mental health, and satisfaction with management. Answers to questions relating to these categories will be averaged for each sub score.
