Participant Flow

We will recruit up to 140 participants. We aim to enroll 6 participants/month, enabling full trial accrual of 94 evaluable participants within 16 months. This estimate accounts for eligible individuals who may refuse based on the distance required to travel for testing and/or treatments at OSU. We plan for expected attrition of participants before they are randomized to one of the two arms and between surgery and the primary timepoint.

Long wait times (8-10 weeks) are common between the clinic visit when participants are enrolled and scheduled surgery date, and it is also common for surgeries to get postponed because of various medical reasons. During this time period some participants lost interest in the study and decided to withdraw. Enrolled participants who were found to have hernia widths \< 2.0cm during surgery were withdrawn before assignment. For these reasons, 26 enrolled participants withdrew before group assignment.

PROMIS-Physical Function is a computer-adaptive patient-reported questionnaire asking questions about physical function. The responses are converted to a t-score which is then reported as a percentile, where 50th percentile represents the average individual. Higher scores indicate greater physical function. This outcome is reported as a change in percentile, where a change of 0 indicates no change in physical function between the two timepoints and a positive change in percentile points indicates an improvement in physical function relative to the rest of the population.

PRIMARY outcome

Timeframe: Baseline before surgery, 10 weeks after surgery

Population: The number of participants for this outcome measure is less than the overall population because some participants were unable to come for in-person testing at this timepoint.

Sit on an inflated cushion that creates an unstable surface for 60 seconds with eyes closed and arms crossed while counting to a metronome. The raw measurement is the center of pressure excursion (cumulative amount of postural sway) of the participant during the 60 seconds. QUeST is scored as a scaled Z-score, where 0 represents the mean value for a healthy control population. A negative score indicates how many multiples of the standard error of measurement the participant is worse than the mean value for a healthy normal population. A positive change indicates improvement in core stability, with an MCID for change ≥1. The total range of the measure can be as high as 0 and has no explicit negative bound.

Population: Some participants did not complete this survey at baseline or at this post-operative timepoint.

The Hernia-related Quality of Life Survey (HerQLeS) patient-reported questionnaire asks questions about how abdominal wall function affects activities of daily living, independent mobility, and mental health. The survey is scored on a 0-100 scale, where 100 indicates the highest quality of life and 0 indicates the worst.

Starting seated in a standard chair, stand, walk forward 3 m, turn 180 deg, walk back to chair, sit down. Do all of these as quickly as can be done safely. The test is scored in seconds, and a lower time indicates better mobility.

Population: Trial began with iPAQ-long form but then we switched to iPAQ-short form to reduce participant burden. Hence the smaller number of participants analyzed. In addition, some participants chose not to complete the survey.

Self-reported physical activity questions spanning sedentary behavior, job activity, transportation activity, household activity, and recreational activity. The test is scored in Metabolic Equivalent of Task (MET)-minutes per week. More minutes means greater physical activity, either by increasing time or the intensity of the activity or both.

Patient-reported questionnaire asking questions regarding a recurrence of the hernia based on pain and presence of a physical bulge. A recurrence is determined by if the patient reports thinking the hernia has come back, feeling or seeing a bulge, or having pain or symptoms at the site. A positive response to any of these 3 questions is considered a recurrence. A recurrence is considered a suboptimal outcome.

PROMIS-Physical Function is a computer-adaptive patient-reported questionnaire asking questions about physical function. The responses are converted to a t-score which is then reported as a percentile, where 50th percentile represents the average individual. Higher scores indicate greater physical function. This outcome is reported as a change in percentile, where a change of 0 indicates no change in physical function between the two timepoints and a positive change in percentile points indicates an improvement in physical function relative to the rest of the population.

Participants in the control group will be told upon post-operative discharge that they should follow the post-operative instructions.
Supervised Physical Therapy
n=53 Participants
Participants in the physical therapy group will be scheduled for visits to the physical therapy clinic beginning two weeks after surgery, and will undergo supervised physical therapy treatments approximately twice per week for eight weeks according to a standardized evidence-based post-operative abdominal core surgery rehabilitation program.

OTHER_PRE_SPECIFIED outcome

Timeframe: baseline before surgery, 30 days after surgery

Population: The number of participants for this outcome measure is less than the overall population because some participants were unable to come for in-person testing at this timepoint, and/or they were uncomfortable performing the test.

Sit on an inflated cushion that creates an unstable surface for 60 seconds with eyes closed and arms crossed while counting to a metronome. The raw measurement is the center of pressure excursion (cumulative amount of postural sway) of the participant during the 60 seconds. QUeST is scored as a scaled Z-score, where 0 represents the mean value for a healthy control population. A negative score indicates how many multiples of the standard error of measurement the participant is worse than the mean value for a healthy normal population. A positive change indicates improvement in core stability, with an MCID for change ≥1. The total range of the measure can be as high as 0 and has no explicit negative bound.

Timeframe: baseline before surgery, 6 months after surgery

Population: Some participants did not complete this survey at baseline or at this post-operative timepoint.

The Hernia-related Quality of Life Survey (HerQLeS) patient-reported questionnaire asks questions about how abdominal wall function affects activities of daily living, independent mobility, and mental health. The survey is scored on a 0-100 scale, where 100 indicates the highest quality of life and 0 indicates the worst.

Starting seated in a standard chair, stand, walk forward 3 m, turn 180 deg, walk back to chair, sit down. Do all of these as quickly as can be done safely. The test is scored in seconds, and a lower time indicates better mobility.

Population: Stopped measuring this outcome in favor of iPAQ-short form after a few participants got through the study.

Self-reported physical activity questions spanning sedentary behavior, job activity, transportation activity, household activity, and recreational activity. The test is scored in Metabolic Equivalent of Task (MET)-minutes per week. More minutes means greater physical activity, either by increasing time or the intensity of the activity or both.
