Background and study aims
Osteoarthritis is the most common joint disorder in the United States and one of the leading causes of disability in the elderly. It develops relatively frequently at the trapeziometacarpal joint (TMJ) of the thumb, often as a result of athletic injury or an arduous occupation or hobby. Thumb carpometacarpal osteoarthritis occurs more often in women, typically in their fifth and sixth decade of life. The main cause of thumb CMC osteoarthritis is deterioration of the surfaces of the joint and abnormal bone growth, leading to pain and hand function impairment. The aim of this study is to find out whether mobilization of the TMJ decreases pain and increases pinch and grip strength in patients with thumb carpometacarpal osteoarthritis.
Who can participate?
Patients aged between 70 and 90 with thumb carpometacarpal osteoarthritis
What does the study involve?
Participants are randomly allocated to be treated with either glide mobilization or sham treatment. Participants in the sham treatment group attend the same number of sessions as those in the glide mobilization group, but they receive ultrasound sham treatment for 10 minutes on the dominant hand. Pain, pinch and grip strength are measured before treatment and after one and two weeks.
What are the possible benefits and risks of participating?

| Scientific title | Hypoalgesic effects of glide mobilization on elderly patients with secondary thumb carpometacarpal osteoarthritis - a randomized, controlled trial |
| Study objectives | The aim of this study was to determine whether specific mobilization of posterior-anterior gliding of the trapeziometacarpal joint (TMJ) decreases mechanical hyperalgesia and increase the strength of the tip pinch and tripod pinch in patients with secondary carpometacarpal osteoarthritis in the dominant hand. |

| Intervention | 1. Glide mobilization 1.1. We performed a glide mobilization also known as mobilization of posterior-anterior gliding of the TMJ, taking into account the convex/concave rule 1.2. The direction of decreased joint gliding in a hypomobile joint and thus appropriate treatment can be deduced by this rule 1.3. Movement of a concave joint partner the glide occurs in the same direction 1.4. The form of the joint surface has been considered to induce its gliding movement: a female (concave) joint surface glides in the same direction as the bone movement, while a male (convex) surface is gliding in the opposite direction of the bone movement 1.5. The subject is seated with his arm in the anatomic position, the elbow at 90° flexion, and the forearm and hand with the cubital face downwards and the dorsal face against the body of the physiotherapist 1.7. The physiotherapist takes the right thumb metacarpal bone of the subject with his right thumb and index finger and makes a specific glide mobilization of posterior-anterior gliding of the TMJ for 3 minutes with a 1 minute pause; the action is repeated three times 1.8. The physiotherapist glides the first metacarpal bone in a posterior-anterior orientation 1.9. In the posterior-anterior gliding movement of the first metacarpal bone, the head and body must slide in the same way because the articular surface of the trapezium is convex and the surface of the first metacarpal bone is concave 1.10. The gliding movement respects the rule of convexity-concavity of the joint 2. Sham group 2.1. Participants in the sham group attended the same number of sessions as did those in the glide mobilization group, but they received applying intermittent ultrasound with non-therapeutic actions for 10 minutes on in the hypothenar area of the dominant hand 2.2. Gel was used as required |

| Primary outcome measure | 1. Pain measurement 1.1. The pressure pain threshold (PPT) was measured by using a mechanical pressure algometer (Wagner Instruments, Greenwich, CT, USA) with a 1cm2 rubber-tipped plunger mounted on a force transducer 1.2. The PPT is defined as the minimum amount of pressure that results in the sense of pressure changing to pain 1.3. The mean of three measurements (intra-examiner reliability) was calculated and used for the main analysis 1.4. The range of values of the pressure algometer was 0 to 10 kg, with a minimal sensibility of 0.1 kg 1.5. For these specific cases, the algometry has higher reliability (Intra-class correlation coefficient [ICC]=0.91, Interval confidence [IC] del 95%: 0.82-0.97) for PPT measurement in older patients 1.6. In addition, previous studies have reported an intra-examiner reliability for this procedure ranging from 0.6 to 0.97, and the inter-examiner reliability ranged from 0.4 to 0.98 1.7. PPT measurements were collected at both thecarpometacarpal (CMC) joint at the bottom of the anatomical snuffbox and tubercle of the scaphoid bone 2. Strength measurements 3. Pinch strength 3.1 The pinch strength was measured by a mechanical pinch gauge (Baseline, NY, USA) while the patient was in the sitting position with the shoulder adducted and neutrally rotated and the elbow flexed at 90° 3.2. Two different measurements were taken: first, the tip pinch between the index finger and thumb and, then, the tripod pinch between the index and medial fingers and the thumb 3.3. The reliability of this procedure to measure the pinch strength has been found to be on the order of 0.93 4. Grip strength measurements 4.1. Grip strength measurements were taken with a grip dynamometer (Baseline, NY, USA) while the patient was also in the sitting position, which has a precision and reliability of ± 3% for grip strength measurements 4.2. The reliability of the measurements was expressed by ICC between 0.82 and 0.97 for grip strength measurements 5. Pinch strength 5.1. The pinch strength was measured by a mechanical pinch gauge (Baseline, NY, USA) while the patient was in the sitting position with the shoulder adducted and neutrally rotated and the elbow flexed at 90° 5.2. Two different measurements were taken: first, the tip pinch between the index finger and thumb and, then, the tripod pinch between the index and medial fingers and the thumb 5.3. The reliability of this procedure to measure the pinch strength has been found to be on the order of 0.93 |
