Summary

The current study is to evaluate the comparative effects of low-level laser therapy and muscle energy technique on pain, range of motion, and functional results in diabetic patients with frozen shoulder. This research aims to enhance the existing data on managing diabetes-related musculoskeletal issues by assessing the comparative advantages of various therapies, therefore assisting physicians in choosing appropriate, patient-centred rehabilitation procedures.

Conditions

• Frozen Shoulder

Interventions

Type	Name	Description
OTHER	Low-Level Laser Therapy (LLLT)	Participants received LLLT using a gallium-aluminium-arsenide (Ga-Al-As) diode laser device (BTL-5000, UK). The laser operated at a wavelength of 830 nm and a power output of 100 mW. Irradiation was applied at three sites (anterior capsule, posterior capsule, subacromial area) using a stationary-contact technique for 60-90 seconds each, delivering 4 J/cm² per site. Sessions were administered three times weekly for eight weeks. Conventional Therapy (for both groups): 15 minutes of moist heat (Chattanooga Hydrocollator) Pendulum exercises Passive and active-assisted ROM exercises Isometric strengthening of rotator cuff and scapular stabilizers Postural correction training
OTHER	Muscle Energy Technique (MET)	Participants received MET for major shoulder muscles (internal/external rotators, flexors, extensors). Each contraction was performed at \~20% of maximum effort, sustained for 10 seconds, followed by 5 seconds relaxation, and then passive stretch to new end range. Three to five cycles per muscle group were performed. Sessions lasted \~20 minutes, three times weekly for eight weeks. Conventional Therapy (same as Arm A): 15 minutes of moist heat Pendulum exercises Passive and active-assisted ROM exercises Isometric strengthening of rotator cuff and scapular stabilizers Postural correction training
