Insights
Physical therapy utilization for infants with Congenital Muscular Torticollis (CMT) increases with condition severity. More severe cases (grades 1-3) require more units billed, longer episodes, and more visits.
Area of Science:
- Pediatric Physical Therapy
- Musculoskeletal Disorders
- Infant Health
Background:
- Congenital Muscular Torticollis (CMT) is a common condition in infants.
- Understanding physical therapy utilization patterns is crucial for resource allocation and treatment planning.
Purpose of the Study:
- To investigate the relationship between Congenital Muscular Torticollis severity and physical therapy utilization.
- To analyze how physical therapy service delivery varies across different grades of CMT severity.
Main Methods:
- Retrospective medical record review of 81 infants with CMT over 3 years.
- Analysis of 46 complete care episodes for infants aged 6 months or younger.
- Correlation of physical therapy utilization metrics (units billed, episode duration, visits) with CMT severity grades.
Main Results:
- Physical therapy utilization, including units billed, episode duration, and total visits, increased with CMT severity grades 1 to 3.
- Cervical rotation restriction was positively correlated with total units billed.
- Half of the infants with complete care episodes achieved full resolution of asymmetries.
Conclusions:
- Physical therapy utilization for Congenital Muscular Torticollis is directly associated with condition severity.
- The findings support the use of the 2018 CMT Severity Grading Scale in predicting resource needs.
- Increased severity correlates with higher demands on physical therapy services.
Purpose:
To determine how physical therapy utilization varies with Congenital Muscular Torticollis (CMT) Severity Grading Scale, considering episode of care and clinical practice guidelines.
Methods:
A 3-year retrospective medical record review was conducted. Data were collected for 81 infants receiving physical therapy for CMT. Sample and service characteristics are described; 46 complete records (infants 6 months or younger) were analyzed to determine how physical therapy utilization varied across severity grades.
Results And Conclusions:
Of the 46 infants with complete care episodes, half had fully resolved all asymmetries. Units billed, episode duration, and total visits each increased across CMT severity grades 1 to 3. Cervical rotation restrictions correlated with total units billed, indicating a positive relationship between CMT severity and service utilization.
What This Adds To The Evidence:
This study supports that as CMT severity increases, physical therapy utilization increases for grades 1 to 3 of the 2018 CMT Severity Grading Scale.
