Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Hand grip strength
Time Frame: change between baseline and 4 weeks

Participants will perform three separate handgrip strength tests using a Jamar Plus digital hand dynamometer, (Sammons Preston, Bolingbrook, Illinois).

In each test, participants will do three trials resting for 15 seconds between trials, the average of the three trials will be recorded. To perform the hand grip strength test, the participant will hold the dynamometer in their dominant hand, with the arm at a right angle, and with the elbow by the side of the body. The participant then squeezes the hand dynamometer with maximum isometric effort for at least five seconds. Participants are required to not move any other part of the body and are encouraged to use maximum effort.
