About this trial
The aim of this study is to examine the relationship between hand grip strength, measured in different shoulder positions, and upper extremity muscle strength, and to reveal the clinical significance of position-dependent strength variation.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Being 65 years of age or older
Being an independent volunteer living in the community
Being able to actively use the upper extremities
Having the cognitive level to understand and follow the measurement instructions
Disqualifiers
Presence of severe shoulder pain or rotator cuff pathology
Loss of upper extremity function due to rheumatological disease
Presence of significant visual or vestibular impairment that may affect measurements
Presence of another systemic or musculoskeletal disease that may prevent the safe and accurate completion of tests

Muscle Strenght Assessment
Other interventionHand grip strength measurements will be performed using a calibrated hydraulic hand dynamometer (JAMAR®). Measurements will be performed according to the standard protocol recommended by the American Society of Hand Therapists: the participant will be positioned in a seated position with shoulder adduction and neutral rotation, elbow 90° flexion, forearm in neutral position, and wrist 0-30° extension. Three repetitions will be performed for each position, with a 30-second rest period between repetitions to minimize fatigue, and the highest value (kg) will be used in the analysis. Hand grip strength will be assessed in four different shoulder positions: (1) standard measurement position, (2) shoulder 90° flexion, (3) shoulder 90° abduction, and (4) shoulder 30° extension. The measurement order will be randomized to minimize learning and fatigue effects. All measurements will be performed by the same researcher independent of the researcher performing the measurements.

Hand grip strength measurements
Hand grip strength measurements will be performed using a calibrated hydraulic hand dynamometer (JAMAR®, Lafayette Instrument, USA). Measurements will be performed according to the standard protocol recommended by the American Society of Hand Therapists (ASHT): the participant will be positioned in a seated position with shoulder adduction and neutral rotation, elbow 90° flexion, forearm in neutral position, and wrist 0-30° extension (Fess and Moran, 1981; Roberts et al., 2011). Three repetitions will be performed for each position, with a 30-second rest period between repetitions to minimize fatigue, and the highest value (kg) will be used in the analysis. Hand grip strength will be assessed in four different shoulder positions: (1) standard measurement position, (2) shoulder 90° flexion, (3) shoulder 90° abduction, and (4) shoulder 30° extension. The measurement order will be randomized to minimize learning and fatigue effects. All measurements will be performed by the same research
