Immediate effects of Mulligan and Maitland mobilization techniques on grip strength and grip force sense in healthy young women
Design
A single-blind study with two arm parallel groups with outcome assessment.
Settings and conduct
This study is conducted at Shahid Beheshti University of Medical Sciences, Tehran, Iran. The Maitland group will receive 3 minutes of grade III passive Maitland mobilization on the proximal row of the carpal bones, especially scaphoid, lunate and triquetrum (Radiocarpal extension). While the Mulligan group will receive 3 sets of 6 lateral glide for non–weight- bearing wrist flexion and extension with overpressure. Participants are not aware of the type of technique.
Participants/Inclusion and exclusion criteria
Inclusion criteria: females (age 18- 30 years) with normal BMI between 20-25 who state that they are healthy and have no problem (asymptomatic). The following are considered as exclusion criteria: The job of the participants depends on heavy manual tasks, a history of carpal tunnel syndrome, wrist tendonitis, fracture and immobilization of the wrist or hand during the 6 previous months. Also receiving manual therapy techniques such as massage, joint mobilization, muscle energy techniques, manipulation during the 6 previous months. In addition, if the participant is not interested in remaining in the study, she would be excluded.
Intervention groups
The Maitland mobilization group and the Mulligan mobilization group.
Main outcome variables
Grip strength, absolute, constant and variable errors were assessed at
baseline and immediately after interventions were applied to participants.

Intervention groups
1
Description
Intervention group one: Maitland mobilization grade III with a frequency of 1 Hz is applied on the subject’s wrist to promote wrist extension. In grade III of Maitland mobilization technique, a large amplitude of oscillating mobilizing movements are applied rhythmically to the barrier of the range of movement. Application of the Maitland mobilization technique takes 3 minutes. In this technique, the subject is in the supine position and her forearm is placed in mid position. The physiotherapist is standing in front of the subject and grasps the radio-carpal joint of the dominant hand. Therapist’s both thumbs are placed on the dorsal side of the proximal carpal row just distal to the radial and ulnar styloid processes. Thumb and index fingers hold the scaphoid, lunate and partially triquetrum. Other fingers are placed on the palmar side of carpal bones. Before beginning the mobilization in palmar direction, joint slack is taken. Index fingers and thumbs are the major contact points which apply the force. Extension movement is applied through local grip with simultaneous wrist extension. Oscillation is finished while forearm turns back to primary position(12).

Description
Intervention group: The technique was done in 3 sets of 6 movements and lasted about 2/5 minutes. The Mulligan technique includes carpal lateral glide with non-weight bearing wrist flexion/extension. The subject is in sitting position with the elbow in 90˚ flexion, the forearm in mid pronation, the wrist in resting position and the hand in neutral position. The therapist is in front of the subject and fixes the distal end of the radius laterally with the first web space. The therapist’s other hand grasped the medial side of the subject’s wrist joint. Then through the first web space a lateral glide was applied to the proximal carps. While the therapist was maintaining the lateral glide, the subject was asked to flex and extend her wrist and apply the pressure at the end of movement in favor of wrist extension. If required, slight adjustments were made to the intensity and direction of the lateral glide. Because the wrist joint was small, the mobilization was done slowly.
