the evidence & framework

Built on theory and research

ErgoMama is guided by the Person-Environment-Occupation-Performance (PEOP) model and the Occupational Therapy Practice Framework (OTPF-4), and grounded in the postpartum musculoskeletal literature.

guiding model

The PEOP model in action

Developed by Christiansen and Baum (1991), PEOP examines how personal factors, environment, and occupational demands interact to shape performance. ErgoMama targets each component.

Person

The mother

Postpartum recovery, joint laxity, fatigue, pain, and ergonomic awareness — addressed through body-mechanics education.

In PEOP, the “Person” is everything a mother brings to a task — her body, her energy, what she knows, and how she moves.

Environment

The setup

Crib and car height, changing stations, and carriers — addressed through home adaptation and equipment recommendations.

The “Environment” is everything around the task — the spaces, heights, and tools that make safe movement easier or harder.

Occupation

The tasks

Lifting, feeding, transferring, and carrying — the routine childcare occupations at the center of the content.

“Occupation” means the meaningful activities that fill a person's day — for a new mom, the everyday work of caring for her baby.

Performance

The outcome

Safer movement patterns, reduced injury risk, and sustained engagement in caregiving occupations.

“Performance” is what happens when the three come together — how safely and sustainably the caregiving actually gets done.

scope of practice

Anchored in the OTPF-4

The OTPF-4 (AOTA, 2020) identifies these as core occupational therapy domains — each one ErgoMama directly supports through education and environmental modification.

Domain

Caregiving

Caring for others — for a new mom, all the hands-on work of looking after her baby: feeding, bathing, lifting, soothing.

Domain

ADLs

Activities of Daily Living — the basics of caring for your own body, like bathing, dressing, and eating, which pain can make harder.

Domain

IADLs

Instrumental ADLs — the bigger tasks that keep a household running: errands, meals, laundry, and managing all that baby gear.

Domain

Health management

Looking after your own health — rest, recovery, managing pain, and building habits that keep you strong for the long run.

The evidence base

Pain is prevalent

97.3% of postpartum women experience musculoskeletal pain, affecting the low back, neck, shoulders, and upper extremities, and interfering with caregiving, daily activities, and sleep.

Adams et al., 2023; Sanders & Morse, 2005; Algabbani et al., 2025; Weis et al., 2021

Tasks drive risk

Biomechanical and observational studies show that lifting car seats, asymmetrical carrying, bending, and twisting during routine childcare alter posture and load distribution, increasing musculoskeletal strain.

Brown et al., 2004; Vincent & Hocking, 2013; Pehlivan et al., 2025; Havens et al., 2020; Li et al., 2023

Education is missing

Only 24% of postpartum women report ever receiving ergonomic or injury-prevention education. Post-discharge education prioritizes infant care while overlooking maternal body mechanics.

Adams et al., 2023; Vincent & Hocking, 2013; Koyasu et al., 2015; Madden et al., 2022

OT is the fit

Task analysis, body-mechanics education, and environmental modification — core occupational therapy tools — directly address these biomechanical risks and support occupational performance.
