The Effectiveness of Cross-training on an Immobilised Forearm

The cross-training phenomenon is the increase in muscle strength in the contralateral limb when one limb is exercised. Limited studies have shown that it prevents immobilisation-induced muscle weakness in healthy volunteers. The aim of this study was to evaluate the effect of strengthening the contralateral extremity on muscle strength and range of motion in the immobilised extremity in patients who had undergone immobilisation for forearm fractures.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Traumatic unilateral forearm fracture (treated surgically or conservatively and immobilised in a cast)

Exclusion criteria

  • Previous upper limb surgery/joint disease - deformity affecting hand-wrist function
  • Any neurological condition affecting the upper extremity (stroke, Parkinson's disease; multiple sclerosis, reflex sympathetic dystrophy, peripheral nerve injury)

Treatment and study plan

isokinetic strengthening exercise

Procedure

Participants' isokinetic strength measurements will be assessed using the Cybex II Humac Norm isokinetic dynamometer. A strengthening programme will be performed for a total of 12 sessions, 3 days a week for 4 weeks, at 20 degrees of flexion, 20 degrees of extension, 60-90 and 180 degrees/s speed.

At the beginning and end of the 12th session, isokinetic and isometric muscle performance tests will be performed on the healthy wrist, and isometric wrist flexor and extensor strength measurements will be performed in neutral position 1 week after removal of the cast on the fractured wrist.

conventional exercise programm

Procedure

The immobilised limb was given finger grip exercises.

Primary outcomes

  1. Wrist isometric flexion muscle strength

    Time frame: 1 year

    The isometric flexion strength of the fractured wrist will be measured using an isokinetic dynamometer at the first week after immobilisation has ceased.

  2. Wrist isometric extansion muscle strength

    Time frame: 1 year

    The isometric extansion strength of the fractured wrist will be measured using an isokinetic dynamometer at the first week after immobilisation has ceased.
