Clinical Trial Summary

The goal of this clinical trial is to learn more about and compare the effectiveness of standard of care (SOC) physical therapy (PT), PT with photobiomodulation therapy (PBMT; low-level laser therapy), PT with shockwave therapy (SWT; high-energy acoustic wave therapy), and PT with PBMT and SWT, to improve function, decrease pain, and resolve symptoms in individuals with non-insertional Achilles tendinopathy. The main question it aims to answer is:

• What is the most effective treatment method for non-insertional Achilles tendinopathy?

Participants will

Researchers will compare PT, PT + SWT, PT + SWT and PBMT to assess the most effective treatment for Achilles tendinopathy.

Description:

Non-insertional Achilles Tendinopathy (AT) is a common overuse injury in adults who are both athletes and nonactive. Tendinopathy occurs when there is either a failed healing response or the failure of normal turnover or remodeling response, and results in pain and limited movement. In the military, lower-extremity injuries due to overuse, (e.g., AT) are the most common category of injuries. The most common treatment of choice for AT is exercise loading programs, however eccentric strengthening (ECC) may only improve symptoms in approximately 60% of patients. Laser-induced photobiomodulation (PBM) has been shown to increase cell proliferation and metabolism, which may aid in the repair and remodeling process. Studies have found that PBM was effective in the treatment of AT. Extracorporeal shockwave therapy (ESWT) is a process in which energy is delivered to the muscles or tendons for pain relief. Current literature supports the use of ESWT as an effective treatment for AT in combination with ECC. Overall, studies indicate that ESWT and photobiomodulation therapy (PBMT) will be effective in treating tendon injuries such as AT, however, these treatment methods have not been evaluated in comparison or combination with each other. The sub-section of AT amongst Active-Duty personnel has very limited research and given the high prevalence, should be addressed. Therefore, our study will compare three different treatment arms utilizing traditional physical therapy (PT), PT plus ESWT, PT plus PBMT, and PT plus ESWT and PBMT. Both self-reported questionnaires and measured outcomes will be used to assess the most effective treatment for AT.

Intervention

Other:
• Physical Therapy
All participants may complete a PT program as standard of care (SOC) treatment addressing individual strength, mobility, and flexibility deficits in both proximal (e.g. spine and hip girdle) along with distal (thigh, leg, and foot/ankle) muscle groups. The provider may also use other modalities to address distal issues. To standardize the loading program, all participants will be given an at-home exercise program designed by Dr. Karin Sibernagel for progressive Achilles tendon loading. The participants will also follow the University of Delaware Return to Sport protocol for return to running. This will be completed alongside the standard of care PT participants will be receiving.

Device:
• Shockwave Therapy
A medical provider will conduct SWT on study participants using the OrthoPlus Ultra 100. This Extracorporeal Pressure Activation Treatment device will be used at a radial shockwave of 3000 counts treatment settings of 15 Hz minimum 2 bars with a focus applicator head at mid-portion of Achilles using clinical focusing technique, and 3000 counts at 15 Hz minimum 2.5 bars using broad oscillator to myotendinous region and over symptomatic areas of gastrocnemius and soleus, treatment will be applied distally to proximally to facilitate lymphatic return adjusting treatment air pressure and amount of force applied by applicator head by patient comfort. The maximum setting for each treatment applicator will be 4 bars of air pressure, and the first 500 counts using each applicator will be applied at 1.5 bars to help desensitize the tissue prior to increasing energy settings. The settings used for each participant will be recorded and followed in a similar approach to treatment.
• Photobiomodulation Therapy
PBMT is delivered with the LightForce® XPi 25W device through the Smart Hand Piece technology. The therapy is transmitted with a rolling glass massage ball at 10 Joules/cm^2 that is applied in a serpentine manner over the site of injury.
