Clinical Trial Summary

The patients with distal radius fracture treated with immobilization (cast) and percutaneous pinning it will be to able to participate in this randomized trial. The investigators will be able to determine if the laser acupuncture is a good therapy for the rehabilitation in this type of patients. And if they are more comfortable to begin his rehabilitation exercise after the application of this therapy

Description:

Distal radius fractures are very common, ranging between 17 and 20% of all diagnosed fractures, and are the most common fractures treated by orthopedic surgeons in adult patients. It is defined as a fracture of the distal radius, which is less than 2.5 cm from the radiocarpal joint. Usually it is the result of falling on the outstretched hand. These fractures occur in all age groups and a bimodal distribution is observed with a peak incidence predominantly young adult patients and another peak in older women.

In order to achieve successful functional results in distal radius fracture both an adequate treatment and timely and specific rehabilitation are required. The distal radius fracture guidelines generally indicate that rehabilitation therapy should begin at four to six weeks post injury or surgery after cast or external fixator is removed initiating passive/active ranges of motion exercises for the fingers, wrist and forearm. Patients are encouraged to use the wrist at home for light activities. At nine to 12 weeks post injury patients can initiate grip strengthening.

There is limited available literature on the effect of acupuncture in the treatment of fractures. Two case reports claim to have achieved an acceleration of bone healing and pain management of patients with proximal humerus fracture when treated with a combination of acupuncture, electro-acupuncture and herbal medicine. Another study concluded that electroacupuncture plus radiation therapy with infrared rays and passive exercises was clearly superior to therapy with only exercises after surgery for humerus fracture.

There is a modality of acupuncture using low level laser therapy, which is useful for tissue regeneration in general and to stimulate acupuncture points. Current clinical research has confirmed the therapeutic usefulness of laser acupuncture in and equine laminitis and in humans in treating myofascial pain, tennis elbow, knee osteoarthritis and other musculoskeletal diseases.

The low level laser therapy, is a type of noninvasively phototherapy that has been shown to modulate various biological processes depending on the power density, wavelength and frequency. A recent study using rats showed that laser stimulation of acupuncture point (located in the leg) caused a significant antinociceptive effect controlling the behavior induced in rats caused by pain after peritoneal injection of acetic acid and injection of formalin in rat paws. The effect is mediated by activation of the opioidergic and serotoninergic systems (5HT-1 and 5HT-2A receptors).

Investigators will try to determine whether laser acupuncture has a positive effect on the rehabilitation of patients with distal radius fracture and to establish a safe therapy without adverse effects that may alleviate pain and restore the functionality of the joint as soon as possible.

This study will be a prospective, longitudinal, randomized, double-blind trial which will include 32 volunteers. All patients with a diagnosis of distal radius fracture type 23-A2, A3, B1, and B2 of the Orthopedic Trauma Association classification that comply with the inclusion criteria will be included. Patients will be randomly assigned to one of two groups: control or experimental group.

The sessions will start as soon as the patient has their cast removed. Control group will receive conventional rehabilitation exercises and "fake" laser acupuncture (device turned off). Experimental group A will receive treatment with conventional rehabilitation plus real laser acupuncture on the following points: bilateral Hegu (IG4), ipsilateral Yangxi (IG5), ipsilateral Yangchi (SJ4), ipsilateral Yanggu (ID5), ipsilateral Waiguan (SJ15), ipsilateral Daling (PC7), contralateral Taixi (R3), contralateral Shenmai (V62) and contralateral Kunlun (V60). All patients will receive a total of 10 sessions with a frequency of 3 times a week. The laser that will be used in this study is a low level laser therapy device (980nm, 50 mW). Each acupuncture point will be irradiated for 30 seconds at 8,000 Hz.

All patients will undergo clinical evaluation to assess improvement using the Patient-Rated Wrist Evaluation Scale. Patients also will be evaluated with the Visual Analogue Scale. The investigators will also measure improvement in range of motion of the wrist (flexion, extension, radial deviation, ulnar deviation, pronation and supination) and grip strength.

The first assessment will be made right before starting rehabilitation and acupuncture, the day of the 5th session, again on the day of the 10th session and finally one week after completing the 10 sessions. All evaluations should be performed by blinded investigator. The investigators will compare the two groups to determine the degree of improvement with each treatment modality used.

Intervention

Procedure:
• Rehabilitation
The investigators will be apply fake laser therapy in the patients with distal radius fracture, with the device in an off position; plus the patients will be teaching to do rehabilitation exercise in flexion, extension, pronation and supination of the wrist and forearm, and to do cubital and radial deviation exercise. The investigators delivered to all patients a graphic demonstration of the exercise

Device:
• Low Lever Laser acupuncture
The investigators will be used a low lever laser device, to apply in ten selected acupuncture points, each point will be irradiated for 30 seconds at 8000 Hz, this therapy is useful for tissue regeneration and stimulate the acupuncture points, plus an antinociceptive effect.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Patient-Rated Wrist Evaluation (PRWE)	The PRWE assesses pain and the inability to perform daily acitivities. Is a 15-item questionnaire designed to measure wrist pain and disability in activities of daily living. It yields a score of 0 to 100, with lower scores indicanting better performance.; Only the final results of the study are reported.	6 weeks
Secondary	Wrist Mobility	The degrees of wrist mobility in flexion, extension, pronation, supination, and radial and ulnar deviation were measured in all patients.; Only the final measures of movements of the study are reported.	6 weeks
Secondary	Visual Analogue Scale (VAS)	The VAS has a score of 0 to 10. The lowest score (0) represents the absence of pain, while the highest score (10) corresponds to the maximum pain possible.; Only the final results of the study are reported.	6 weeks
