Brief Summary

One of the most common complications after breast cancer surgery is a functional limitation of the upper body. Up to 67% of breast cancer patients experience arm or shoulder impairment, including pain, numbness, loss of strength, and reduced ROM, after surgery. Graded motor imagery is effective in reducing pain interference with function using a graded sequence of strategies including left/right judgements (implicit motor imagery), imagined movements (explicit motor imagery) and mirror therapy.

Outcome Measures

Primary Outcomes (2)

• Digital goniometer

  A device which measures joint ranges.

  From baseline to 6 weeks

• Handgrip dynamometer

  A valid tool for measuring handgrip strength in kilograms that provides an objective overview of upper limb functional integrity

  From baseline to 6 weeks

Secondary Outcomes (2)

• Visual analog scale

  From baseline to 6 weeks

• Shoulder Pain and Disability Index

  From baseline to 6 weeks

Study Arms (2)

Group A (study group)

ACTIVE COMPARATOR

This group includes 27 patients who will receive graded motor imagery (GMI) along with the conventional physiotherapy (It will include exercise like codman's pendulum exercises in flexion-extension, abduction-adduction, and circular motion, active assisted ROM exercises with a wand, capsular stretching, wall ladder, and shoulder wheel exercises). GMI is consists of a three-step process. Each step of will be carried out for two weeks, for 30 minutes on two separate days, for total 6 weeks

Other: Graded Motor Imagery (GMI); Other: Physical therapy program

Group B (control group)

PLACEBO COMPARATOR

This group includes 27 patients who will receive conventional physiotherapy treatment for improving ROM and decreasing pain. It will include exercise like codman's pendulum exercises in flexion-extension, abduction-adduction, and circular motion, active assisted ROM exercises with a wand, capsular stretching, wall ladder, and shoulder wheel exercises, 2 times / week for 6 weeks

Other: Physical therapy program

Interventions

Graded Motor Imagery (GMI) OTHER

1. Left/right judgements: It includes left/right judgments of photographs that depict the affected area. 2. Imagined movements: Movement visualizations will be performed. 3. Mirror therapy: It includes observation of the movements of unaffected body part in the mirror, 2 times / week for 6 weeks.

Group A (study group)

Physical therapy program OTHER

It will include exercise like codman's pendulum exercises in flexion-extension, abduction-adduction, and circular motion, active assisted ROM exercises with a wand, capsular stretching, wall ladder, and shoulder wheel exercises, 2 times / week for 6 weeks.

Also known as: A group of exercises
