A Comparative Study of PENS VS Shockwave Therapy on Lateral Epicondylitis in Housekeeping Staff

Abstract

BACKGROUND:  Lateral Epicondylitis is a pathologic condition of the wrist extensor muscles at their origin on the lateral epicondyle. Work-related musculoskeletal disorders are the most frequent health problems affecting housekeeping staff, they use uncomfortable postures, over extensions, forceful exertions, and repetitive movements over a long period of time, Lateral epicondylitis is one such condition.

METHODOLOGY: Simple random sampling was used in this comparative study, which had a sample size of 48. There were two groups, each with 24 participants: Group A (PENS) and Group B (ESWT). Pressure Algometer and Patient Rated Tennis Elbow Evaluation were primary outcome measures and Visual Analogue Scale and Goniometry were used as secondary outcome measures.

RESULTS:

FOR GROUP A (PENS ) AND B (SHOCKWAVE THERAPY) Regarding ROM and PRTEE  Between group analysis did not Report Statistically Significant Difference (P>0.05), Within Group Analysis did not report Statistically Significant difference(P>0.05)in ROM and reported statistically significant difference in PRTEE.Regarding VAS and Pressure Algometer Within group analysis reported statistically significant difference (P<0.05), Between group analysis Reported Statistically Significant  Difference (P<0.05) regarding VAS and not reported statistically significant difference (P>0.05)regarding Pressure algometer.There was significant improvement seen in pain and functional disability based on VAS, PRTEE, Pressure Algometer in both groups ,On comparison both group showed improvement post 6 session with statistical significance.

CONCLUSION:  Statically both PENS and ESWT are adequate enough for abating pain, improving functional disability, improving pain pressure threshold and painless Range of motion of elbow flexion in housekeeping staff with lateral epicondylitis. Housekeeping staff have work shift of 8 hours approximately which include long hours of mopping floor and cleaning window glasses, walls, desks therefore their hand muscles are in continuous stress  .Hence work place analysis, ergonomic modifications and postural correction cannot be overlooked.
