Background: *Adedoyin RA PhD (Department of Medical Rehabilitation, Obafemi Awolowo University, Ile-Ife, Nigeria) Erhabor GE, MBBS, Obaseki D.O MBBS, (Department of Medicine, Obafemi Awolowo University, Ile-Ife), Nigeria Ojo O, BMR, PT, Oyadeyi O, BMR, PT (Department of Medical Rehabilitation, Obafemi Awolowo University, Ile-Ife, Nigeria).

Evidence exist that COPD results in prolonged activity limitation and can quickly reverse the hard won benefits of exercise programme. There is lack of evidence on the physical fitness status of patients who have post tuberculosis lung disorder (Post-TBLD) who usually show stable restrictive or mixed ventilatory disorder. The study compared some physical fitness indicators of patients with COPD and patients with post tuberculosis lung disorders.

Methods:
Thirty six (19 males and 17 females) with COPD patients and 32 (16 males and 16 females) age matched patients with post tuberculosis lung disorders were enrolled in the study. Patients who had apparent complications from COPD were excluded. Non of the subjects showed any musculoskeletal disorders, that could limit the exercise participation. All the subjects underwent a 6-minutes walk test over a 30 meters course on a level walk way at a self determined speed. The pre and post exercised blood pressure, heart rate were assessed. Hand grip strength was measured using standardized procedure with the aid of Jamar dynamometer. Estimated maximum oxygen consumption (VO2) was calculated using ACSM equation.

Results:
Anthropometric parameters of the 2 groups are comparable. There were no significant differences in distance covered in 6minutes, estimated VO2 and grip strength between the 2 groups (p >0.05) between the two groups. Estimated V02 correlate positively with grip strength (COPD, r=0.546; post-TBP, r=0.576); and also 6-min walk distance (COPD, r= 0.998; post-TBLD, r= 0.997).

Conclusion:
COPD and post-TBLD are both associated with reduced functional capacity compared with apparently healthy individuals of similar age group. Functional assessments using grip strength and 6-min walk may be useful in monitoring progress of these conditions during rehabilitation.
