Grip strength measurements at two different wrist extension positions in chronic lateral epicondylitis-comparison of involved vs. uninvolved side in athletes and non athletes: a case-control study

Table 2 Grip strength comparisons within- and between- groups.

Group	Wrist extension position (in degrees)	Side of testing. Symptomatic- S Asymptomatic- AS	Grip strength in pound sq.inch (Mean ± SD)	Comparison within-group between sides and between positions. Mean difference (Mean ± SD)	Comparison between athletes and non-athletes. Mean difference (Mean ± SD)
Athletes	15°	S ₁	27.75 ± 4.2	S₁S₂ 2.5 ± .67	S₁S₃ 11.3
		AS ₁	31 ± 3.7	S₁AS₁ 2.25 ± .95

Non-athletes	15°	S ₃	16.45 ± 4.2	S₃S₄ 2.27 ± .67	AS₁AS₃ 10.1

Within-group comparison was done between symptomatic and asymptomatic sides at both 15 and 35 degrees wrist extension positions and between-group comparison was done between athletes and non-athletes.
