Simple Explanation

This study looked at the shoulders of people with spinal cord injuries who use manual wheelchairs to see how common rotator cuff and biceps problems are. The researchers found that most participants had some level of tendon damage (tendinopathy) and many had partial tears in their rotator cuff tendons. Those with tears were generally older and had used a wheelchair for a longer time. The study suggests that regular check-ups for shoulder problems in this group should focus on age and years of wheelchair use, rather than just relying on what the patient reports about pain.

Study Duration
Not specified
Participants
Forty-four adult MWC users with SCI (36 men and 8 women) with an average age (SD) of 42 (13) years. SCI levels ranged from C6 to L1; complete and incomplete SCI.
Evidence Level
Cross-sectional study

Key Findings

  • 1
    The prevalence of any tendinopathy across the rotator cuff and the long head of biceps tendon was 98%.
  • 2
    The prevalence of any tears was 68%.
  • 3
    Participants without tendon tears were significantly younger (P < 0.001) and had been wheelchair user for a significantly shorter time (P = 0.005) than those with tendon tears.

Research Summary

This study investigated the prevalence of shoulder pathologies in manual wheelchair users with spinal cord injury using MRI. The results showed a high prevalence of tendinopathy and partial-thickness tendon tears, particularly in the supraspinatus and infraspinatus tendons. Age and duration of wheelchair use were significant risk factors for tendon tears, while patient-reported pain was not strongly associated with the presence of these pathologies.

Practical Implications

Monitoring Strategies

Strategies for monitoring shoulder pathologies in manual wheelchair users with spinal cord injury should consider age and years of wheelchair use.

Early Intervention

Early intervention might reduce the rate of disease advancement.

Further Research

Further longitudinal investigation with a larger population of MWC users with SCI is necessary to elucidate the natural history of shoulder pathology progression and pain development due to MWC use.

Study Limitations

  • 1
    Relatively small sample size
  • 2
    Cross-sectional data limited analysis of age and wheelchair use effects
  • 3
    Addition of multiple readers would improve the rigor of the study.
