OBJECTIVE: To assess the relation of pectoralis minor muscle (PMm) length and
extensibility to shoulder pain, shoulder girdle motion, and duration of manual
wheelchair (MWC) use, and to compare differences in muscle length, muscle
extensibility, peak humeral elevation, and pain among groups based on duration of
wheelchair use. DESIGN: Cross-sectional cohort study.
SETTING: Laboratory
setting. PARTICIPANTS: Individuals with spinal cord injury (SCI) who used an MWC
for daily community and home mobility (N=22; 18 men; mean age, 41.7y; duration
wheelchair use, 14.6y). Participants were stratified into groups based on
duration of wheelchair use: <5 years (n=6), 5 to 15 years (n=8), and >15 years
(n=8). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Clinical measures of
PMm length and extensibility, shoulder girdle motion, and shoulder pain
(Wheelchair User's Shoulder Pain Index). RESULTS: Significant high correlations
were found among duration of wheelchair use, passive PMm length, passive PMm
extensibility, and peak humerothoracic elevation. Moderate correlation of peak
humerothoracic elevation to pain was found. Individuals with >15 years wheelchair
use had reduced PMm extensibility and reduced peak humerothoracic elevation than
those with <5 years duration of use. CONCLUSIONS: To our knowledge, this is the
first investigation to identify the association of reduced PMm extensibility with
reduced shoulder girdle mobility, pain, and duration of wheelchair use in
individuals with SCI.
