Brief Summary
Proximal humerus fractures (PHFs) frequently occur in the elderly and osteoporotic population, but these fractures are also common in individuals under age 60 years. Conservative treatment of PHF usually involves a short period of immobilization followed by orthopedic rehabilitation. However, the severe pain of some patients with fractures limits their participation in the exercise programme, and shoulder muscle atrophy and frozen shoulder may occur in these patients due to immobilization. There are conflicting results regarding the use of physical therapy modalities in the shoulder pain management. Interferential current (IFC) therapy is believed to be effective for the pain-relieving through several mechanisms. Although IFC has been investigated in many painful shoulder disorders, there is no reported study on the effectiveness of IFC therapy in patients with PHF. This study aimed to investigate the effectiveness of IFC added to exercise on shoulder function, pain, and disability compared with placebo in patients with conservative treated PHF. Patients were evaluated within the first week of PHF and divided into two groups to receive either IFC or sham using a simple randomization method. The orthopedic rehabilitation programme was applied to all patients three times a week for four weeks under the guidance of the same physiotherapist. IFC or sham therapy was applied three times a week for 20 minutes before each exercise session by another physiotherapist. Shoulder functions, pain (visual analogue scale), disability and range of motion was evaluated at the end of the rehabilitation program, at 6-weeks and 18-weeks post-treatment by the physiatrist (ED) who did not know which group the patients belonged to. In addition, the amount of acetaminophen usage was noted at each visit.

Outcome Measures
Primary Outcomes (1)
Constant-Murley Score
The primary outcome was shoulder global function which was measured by the Constant-Murley score (CMS). The questionnaire assesses four shoulder functions: 1) pain; 2) activities of daily living (sleeping, work, leisure); 3) range of motion; and 4) muscle strength. The total score ranges from 0 to 100, with a higher score indicating better shoulder function.
1. At the end of the treatment 2. The second evaluation: Six weeks after the first one (6th week post-treatment) 3. The last evaluation: Three months after the second one (18th week post-treatment)
Secondary Outcomes (2)
Visual Analogue Scale
Visual analogue scale was recorded at the end of the treatment, at 6-weeks and 18-weeks post-treatment
Disabilities of the Arm, Shoulder and Hand (DASH) Score
Disabilities of the Arm, Shoulder and Hand (DASH) Score was recorded at the end of the treatment, at 6-weeks and 18-weeks post-treatment
Study Arms (2)
Rehabilitation and interferential current therapy
ACTIVE COMPARATORFlipping a coin was used for simple randomization (tails - interferential current). In this arm, interferential current therapy was applied to the patients in addition to the rehabilitation program.
Rehabilitation and sham therapy
SHAM COMPARATORFlipping a coin was used for simple randomization (heads - sham). In this arm, sham therapy was applied to the patients in addition to the rehabilitation program.
Interventions
Interferential current or sham were applied to the patients before the each exercise session. Pre-modulated bipolar method with the currier frequency of 4 kHz by a combination therapy unit (Sonopuls 692, Enraf-Nonius) with two electrodes (8×6 cm) was used. One electrode was placed on the lateral part of the deltoid muscle; the other was placed on the trapezium muscle close to the shoulder. Subjects were told that in order to produce an effect, the intensity of the stimulator must be maintained at a "strong but comfortable level" at all times. The sham interferential current therapy consisted of the placement of the same pads for the same time but no electrical stimulation was applied to the probes.
The orthopedic rehabilitation programme was applied to all patients three times a week for 4 weeks under the guidance of the same physiotherapist. The first phase (0-3 weeks) involved the elbow, wrist, and hand active range of motion (ROM) and pendulum (clockwise and counterclockwise) exercises in the 0-2 weeks of the non-displaced fracture. For displaced fractures, elbow, wrist, and hand active range of motion was started immediately, but pendulum exercises were initiated two weeks later. The patients were instructed to continue exercises 3-5 times per day for 30 minutes. After two weeks, active assistive ROM and isometric exercises were performed supine position. During the second phase (3-6 weeks), active forward elevation in supine was carried out and then progressed to sitting and standing position. At the end of the sixth week, a home exercise program was given by the physiotherapist, including resistance exercises using an elastic band (Thera-Band).
Eligibility Criteria
You may not qualify if:
- Any surgery history for shoulder pathologies
- Previous electrotherapy experience before the fracture (to ensure blinding of therapy)
- Any contraindication such as pacemaker, malignancy, pregnancy, etc. for IFC
- Rheumatic disease such as rheumatoid arthritis and ankylosing spondylitis
- Shoulder subluxation; having other fractures in addition to the PHF
- Known or suspected joint infection or a specific condition such as peripheral or central nervous system lesions
- Neoplasm; diabetes mellitus or osteonecrosis
- Any mental disorder that may make it difficult to adapt to exercise
