Detailed Description
-----------------
Frozen shoulder, also known as adhesive capsulitis, is defined as a condition of uncertain aetiology, characterized by significant restriction of both active and passive shoulder motion that occurs in the absence of a known intrinsic shoulder disorder. Prevalence ranges from 2% to 5% in general population. It is relatively more common in women than men, often in non-dominant arm and age between 40 and 60 years. Frozen shoulder was also termed as adhesive capsulitis (AC) due to its chronic inflammatory process. Painful stiffness of the shoulder can adversely affect activities of daily living and consequently impair quality of life. Adhesive capsulitis can be primary or secondary. Primary (or idiopathic) adhesive capsulitis can occur spontaneously without any specific trauma or inciting event. Secondary adhesive capsulitis is often observed after periarticular fracture dislocation of the glenohumeral joint or other severe articular trauma. Dr. Lawrence Jones, an osteopathic physician, is credited with the discovery of the therapy; he initially called it Positional release technique (PRT) and later coined the term strain counterstrain. Originally termed strain-counterstrain, is a therapeutic technique that uses trigger points (TrPs) and a position of comfort (POC) to resolve the associated dysfunction. A gentle and passive technique, SCS has been advocated for the treatment of acute, subacute and chronic dysfunction in people of all ages.A number of studies have reported the use of strain/counterstrain in combination with other interventions for treating a variety of disorders, including chondromalacia patellae, low back pain, and cervicothoracic pain. Active Release Techniques (ART) is a soft tissue method that focuses on relieving tissue tension via the removal of fibrosis/adhesions which can develop in tissues as a result of overload due to repetitive use. The goals of ART are to restore optimal tissue texture, tension and movement, restore the strength, flexibility, function, and relative translation between soft tissue layers, release any soft tissue restrictions, entrapped nerve, restricted circulatory structures, or lymphatic restrictions. ART is used to find the specific tissues that are restricted, physically work on the soft tissues back to their normal texture, tension, and length by using various hand positions and soft tissue manipulation methods. Active release technique and capsular stretch with conventional therapy is more effective in increasing ROM and decreasing pain of frozen shoulder rather alone capsular stretch with conventional therapy. These changes are clinically significant. Both positional release and muscle energy techniques were shown to be effective in improving functional ability of shoulder in Adhesive Capsulitis, but muscle energy technique was better than positional release technique..Both ART and SCS technique play important role in decreasing hamstring tightness but Active Release Technique is more effective physiotherapeutic intervention than strain counterstrain technique in reducing hamstrings tightness instantly. Active Release Techniqueand Strain Counterstrain have been proved to be effective in many conditions like low back pain, chronic neck pain, tennis elbow, CTS and shoulder pain. ART and SCS has also been proved effective in treating upper trapezius, subscapularis SCM, hamstring muscle trigger point in comparison with other treatment protocol. But there is limited studies done on comparing these two techniques i.e ART and SCS for the adhesive capsulitis and specifically the use of ART and SCS for AC induced trigger points in different muscles of shoulder. Hence, the aim of present study is to compare the effectiveness of Active release technique and Strain counterstrain technique in adhesive capsulitis induce trigger points in different shoulder muscle in term of pain, ROM and muscle strength.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: STRAIN COUNTER STRAIN GROUP<br>Strain Counter Strain Technique in combination with conventional physiotherapy | Other: STRAIN COUNTER STRAIN GROUP<br>* Strain Counterstrain Technique in combination with conventional physiotherapy (Hot pack, Codmans exercises, active assisted exercises, Pendulum exercises, Finger Ladder Exercise, Maitland mobilization of shoulder joint. Therapist palpate surrounding and opposing tissues to locate trigger point by using one or two finger pads to monitor fasciculation and MTrP. Hold the POC (position of comfort) until fasciculation decreases significantly or ceases. Average positions hold time while pressure is 90 s to 3 min. Release tissue or joint slowly and reassess. Each patient will receive total 6 sessions (3sessions/week) over a period of 2 weeks. Assessment would be done on baseline and after every three sessions.<br>|
| Experimental: ACTIVE RELEASE TECHNIQUE GROUP<br>Active Release Technique in combination with conventional physiotherapy | Other: ACTIVE RELESAE TECHNIQUE GROUP<br>* Active Release Technique in combination with conventional physiotherapy (Hot pack, Codmans exercises, active assisted exercises, Pendulum exercises, Finger Ladder Exercise, Maitland mobilization of shoulder joint. The targeted muscle will be palpated while the therapist will looks for localized tenderness or trigger points with referred pain elicitation. With the thumb therapist will relieve the trigger point. In ART the particular muscle is taken from shortened to lengthened position or from lengthened to shortened position. Duration of treatment will be 8-15 minutes. Each patient will receive total 6 sessions (3sessions/week) over a period of 2 weeks. Assessment would be done on baseline and after every three sessions.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Numerical Rating Scale (NRS): | In a Numerical Rating Scale (NRS), patients are asked to circle the number between 0 and 10, 0 and 20 or 0 and 100 that fits best to their pain intensity [1]. Zero usually represents 'no pain at all' whereas the upper limit represents 'the worst pain ever possible. | 4th week | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Range of motion | A goniometer is an instrument that measures the available range of motion at a joint. The art and science of measuring the joint ranges in each plane of the joint are called goniometry. | 4th week | 
| Shoulder Pain and Disability Index (SPADI): | The Shoulder Pain and Disability Index (SPADI) is a self-administered questionnaire that consists of two dimensions, one for pain and the other for functional activities. The pain dimension consists of five questions regarding the severity of an individual's pain. Functional activities are assessed with eight questions designed to measure the degree of difficulty an individual has with various activities of daily living that require upper-extremity use. The SPADI takes 5 to 10 minutes for a patient to complete and is the only reliable and valid region-specific measure for the shoulder. To answer the questions, patients place a mark on a 10cm visual analogue scale for each question. Verbal anchors for the pain dimension are 'no pain at all' and 'worst pain imaginable', and those for the functional activities are 'no difficulty' and 'so difficult it required help'. The scores from both dimensions are averaged to derive a total score. | 4th week | 
| Manual Muscle Testing (MMT): | Manual muscle testing (MMT) is a very common practice of orthopedic examination specifically designed to assess function and strength of various muscles, usually when rehabilitating sports injuries or recovering from an illness, MMT grades are usually labelled with the following terms: zero, trace, poor, fair, good, and normal. In addition, manual muscle testing grades can be further described using a numerical scale from 0 through 5. | 4th week |
