ABSTRACT
Background: Effectiveness of any individualized therapeutic modality in reducing pain in frozen shoulder is questionable and the combination of therapies has contradictory results.
Objectives: The purpose of this study was to check the effectiveness of Ultrasound with end range mobilization over Cryotherapy with end range mobilization in alleviating pain of patients with frozen shoulder.
Method: Forty subjects diagnosed to have frozen shoulder were randomly assigned to two groups. Subjects in Group I received Ultrasound and End range mobilization of shoulder while subjects in Group II got Cryotherapy and End range mobilization of shoulder. Both the groups were treated once a day, 6 days a week for 4 weeks. Response to pain was considered as the outcome measure.
Results: Data analysis was done considering p<0.05 as statistically significant and the't' values were estimated. It was found that ultrasound when combined with end range mobilization had a't' value of 1.8342 in comparison to that of cryotherapy combined with End range mobilization group.
Conclusion: Ultrasound with end range mobilization produced better pain relief compared to cryotherapy with end range mobilization and therefore can be recommended as a safe treatment for frozen shoulder.

INTRODUCTION
Frozen shoulder clinically referred to as adhesive capsulitis has been described as a condition of "unknown etiology characterized by gradually progressive, painful restriction of all joint motion with spontaneous restoration of partial or complete motion over months to years"1. Its clinical course is divided into stages of freezing, lasting from onset to between 10 and 36 weeks, characterized by severe pain and a gradual diminution of articular volume, frozen stage lasting between 4 and 12 months when pain decreases gradually but without appreciable improvement in motion and thawing stage which is marked by gradual return of motion and may last between 12 months to few years 2.
Ultrasound therapy (UST), one of the modalities used to treat frozen shoulder elevates tissue temperature to depths of more than 5 cm causing increased collagen tissue extensibility, pain threshold, and enzymatic activity. It also changes nerve conduction velocity, contractile activity of the skeletal muscle.3 Cryotherapy is another important modality which controls pain by directly and rapidly modifying the sensation of pain and controlling the pain transmission with...
