The Effectiveness of Cross-training on an Immobilised Forearm

NCT06562218 | Completed

Brief Summary

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.

Conditions

Forearm Fracture

Keywords

fracture; immobilisation; cross-education; muscle strength

Outcome Measures

Primary Outcomes (2)

• Wrist isometric flexion muscle strength

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

  1 year

• Wrist isometric extansion muscle strength

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

  1 year

Study Arms (2)

cross training group

EXPERIMENTAL

Group whose healthy arm (unbroken side) is strengthened

Procedure: isokinetic strengthening exercise

control group

EXPERIMENTAL

group given conventional exercise to the fractured arm

Procedure: conventional exercise programm

Interventions

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.

cross training group

conventional exercise programm PROCEDURE

The immobilised limb was given finger grip exercises.
