Efficacy of Two Distinct Photo biomodulation Therapy Intensities on Muscle Strength and Fatigue in Type 2 Diabetes Mellitus

Abstract

Background: Diabetes mellitus refers to a collection of metabolic illnesses characterized by deficiencies in insulin secretion, insulin action, or both, as well as disruptions in carbohydrate, lipid, and protein metabolism, resulting in decreased muscular performance. Photo biomodulation therapy is also called as Low-level laser therapy. It has thought to improve muscle strength and minimize muscle fatigue in type 2 diabetes patients. The aim of this research is to determine the effectiveness of two different intensities of low-level laser treatment (LLLT) on muscle strength and tiredness in patients with type 2 diabetes mellitus.

Methods: A quasi-experimental study was conducted on 30 participants with type 2 diabetes mellitus, who were divided into three groups. Pre-interventional measures included the MRC grading scale for strength evaluation and the FSS for tiredness. Experimental group A (n=10) received 5J/cm2 LLLT, experimental group B (n=10) received 7J/cm2 LLLT, and group C (n=10) underwent moderate intensity resistance training, 12 repetitions, 3 sets for ankle plantar flexors and dorsi flexors once a day, four days a week, for four weeks. Post-interventional outcomes were assessed with the MRC grading scale for strength and FSS for fatigue.

Results: The statistical analysis of the data reveals that experimental group B subjects have made significant improvements in their muscle strength and fatigue levels. The p-values for MRC and FSS in experimental group B participants are 0.0002 and 0.0001, respectively.

Conclusions: Low-level laser therapy is beneficial in improving muscle strength and reducing muscle fatigue in people with type 2 diabetes. The statistical analysis revealed that group A (LLLT at 7 Joules of intensity) improved muscular performance more than group B or the control group.
